Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of computer application, in particular to a display device and a poster data scraping method. BACKGROUND

[0002] With the rapid development of television and streaming media technology, users' requirements for the clarity and audio-visual experience of audio-visual content are increasing, and 4K Dolby sound and other ultra-high-definition film sources are widely used. More and more users tend to save such film sources through NAS devices. The management and browsing experience requirements of users for audio-visual content are also increasing. The list or grid layout of the traditional television media center needs the user to know the file name to find or search, which is inconvenient to operate. Therefore, the movie wall function emerges as the times require. This function can be integrated into the pre-installed application of the television manufacturer, the adapted application of the NAS manufacturer, and the third-party application.

[0003] The implementation of the existing movie wall function depends on the poster scraping technology. The mainstream tool needs to perform fuzzy matching between the information of the video file itself, such as the video file name, and an online database. The matching request is initiated through a network API, and the average request for a single film is 3 to 5 times to complete the information matching.

[0004] There may be video files with complex formats, such as Blu-ray original discs, which contain a STREAM subdirectory and multiple m2ts segments. Each video-related file under the directory needs to be scraped accordingly, which may cause repeated scraping, affect the scraping efficiency, and generate a large amount of redundant metadata. SUMMARY

[0005] Therefore, it is necessary to provide a display device and a poster data scraping method to reduce repeated scraping in view of the above technical problems.

[0006] In a first aspect, the present application provides a display device, comprising:

[0007] a display configured to display an image and / or a user interface;

[0008] a controller configured to:

[0009] scan a file directory in which audio-video files are stored, and obtain a storage path of each of the audio-video files, the storage path comprising a folder name at a previous level and an audio-video file name at a last level;

[0010] extract a field from the folder name and the audio-video file name to obtain a metadata field of the audio-video file, and combine the metadata field of the audio-video file to obtain a structured object of the audio-video file;

[0011] Based on the structured objects of the plurality of audio and video files, in the case of identifying the plurality of audio and video files as related files of the same audio and video work, merging the network scraping requests of the plurality of audio and video files to initiate a preset number of network scraping requests, and the preset number is less than the number of the plurality of audio and video files.

[0012] The technical scheme has the following advantages or beneficial effects: The metadata fields are extracted from the folder name and the audio and video file name to form the structured object by scanning the audio and video file storage path, the path hierarchy semantics is fully mined, and the problem of inaccurate matching of non-standard naming files is effectively solved, and the adaptability to non-standard naming scenarios is improved. Based on the core information in the structured object, the related files of the same audio and video work are identified, and the network scraping requests of the related files are merged, thereby effectively reducing the number of network scraping requests, reducing the network transmission bandwidth occupation and the server request pressure, and improving the response efficiency of the scraping request. At the same time, with the help of path information extraction metadata and the same work identification mechanism, the accuracy and relevance of the audio and video file metadata acquisition can be ensured, the problems of resource waste and redundant data caused by repeated scraping are improved, the metadata management process of multiple audio and video files is simplified, and the efficiency and practicability of the overall audio and video file metadata processing are improved.

[0013] In one of the embodiments, the controller performs field extraction on the folder name and the audio and video file name to obtain the metadata fields of the audio and video file, and is configured to:

[0014] The audio and video file name is taken as the current level object, and the metadata fields in the current level object are obtained by performing field extraction on the current level object;

[0015] The last level folder name of the current level object is taken as the current level object, and the step of performing field extraction on the current level object is returned and continued to be executed until the current level object does not have the last level folder name.

[0016] The technical scheme has the following advantages or beneficial effects: The extraction method of gradually tracing back from the last level of the audio and video file name to the last level folder name is adopted, the metadata information contained in each level of the storage path is fully mined, and the problem of metadata omission caused by single level extraction is improved. At the same time, the tracing back extraction logic can fully utilize the path hierarchy semantics, maximize the mining of key information such as classification, year, and technical parameters scattered in the non-standard naming file path, effectively solve the defect of insufficient data integration capability of the prior art, provide more comprehensive and complete metadata support for subsequent structured object construction and same audio and video work identification, and further improve the comprehensiveness and accuracy of metadata processing in complex path and non-standard naming scenarios.

[0017] In one of the embodiments, the controller performs field extraction on the current hierarchical object to obtain the metadata field in the current hierarchical object, which is configured to:

[0018] Call the naming rule template corresponding to the type of the audio and video file to match the current hierarchical object, and in the case of successful matching, obtain the metadata field in the current hierarchical object;

[0019] In the case of failed matching, based on the preset invalid field dictionary, the invalid field in the current hierarchical object is cleaned up; based on the preset valid word dictionary, the current hierarchical object after cleaning is matched to obtain the metadata field in the current hierarchical object.

[0020] The above technical solution has the following advantages or beneficial effects: by calling the naming rule template corresponding to the type of the audio and video file, the current hierarchical object is accurately matched to quickly extract the metadata field, which effectively improves the efficiency and accuracy of metadata extraction in the standard naming scenario. For the case of failed matching, the invalid field in the current hierarchical object is first cleaned up with the help of the preset invalid field dictionary, and then the metadata field is extracted by secondary matching with the preset valid word dictionary, which not only solves the problem of insufficient data integration capability when parsing the file name and difficulty in parsing the semantics of non-standard naming file path, but also further expands the adaptation range of non-standard naming and complex format files, improves the situation of metadata extraction omission or misjudgment caused by non-standard naming, and guarantees the consistency and reliability of metadata field extraction in different naming scenarios, provides high-quality data support for subsequent identification of the same audio and video works and merging of network scraping requests, and comprehensively optimizes the overall effect of audio and video file metadata processing.

[0021] In one of the embodiments, the controller performs field extraction on the current hierarchical object to obtain the metadata field in the current hierarchical object, which is configured to:

[0022] In the case of extracting multiple metadata fields of the same type and the multiple metadata fields of the same type are derived from different levels in the storage path, based on the level distance between the source level and the last level of the metadata field, the metadata field with the smallest level distance is retained in the multiple same metadata fields.

[0023] The above technical solution has the following advantages or beneficial effects: For scenarios where multiple metadata fields of the same type may be extracted from different levels of the storage path, by using the distance between the source level and the last level (the level where the audio / video file name is located) of the metadata field as the criterion, and retaining the metadata field corresponding to the smallest distance, it can accurately filter out metadata information that is strongly related to and semantically fits the audio / video file. This effectively improves the problems caused by metadata redundancy or ambiguity due to the coexistence of multiple levels of the same type of fields. At the same time, this method does not require additional complex verification logic; it can achieve efficient deduplication and accurate filtering solely through the distance between levels. This ensures the uniqueness and accuracy of the metadata fields and provides high-quality data support for subsequent processes such as identification of the same audio / video work and merging of network scraping requests. It further optimizes the metadata processing effect in complex scenarios such as non-standard naming and multi-level paths, improving the practicality and reliability of the overall technical solution.

[0024] In one embodiment, the metadata fields include audio / video titles and audio / video names; the controller performs identification based on the structured objects of multiple audio / video files, and is configured as follows:

[0025] When different structured objects have the same audio and video names and types, the corresponding different audio and video files are identified as related files of the same audio and video work.

[0026] The above-mentioned technical solution has the following advantages or beneficial effects: using audio and video names and types as the basis for identifying the same audio and video work, and identifying related files of the same work by judging the consistency of these two fields in different structured objects, can effectively solve the problem of misjudging multiple fragment files in complex formats such as Blu-ray discs in existing technologies, and avoid repeated scraping caused by misjudging fragment files of the same work as independent files. At the same time, this identification method does not rely on complex additional verification logic, and can quickly associate audio and video files with non-standard naming but consistent core information, further improving the adaptability to non-standard naming scenarios, laying a reliable foundation for subsequent merging of network scraping requests, reducing network dependence, and improving scraping efficiency, and ensuring the relevance and efficiency of audio and video file metadata processing in multiple scenarios.

[0027] In one embodiment, the controller performs a scan of the file directory where the audio and video files are stored to obtain the storage paths of the various audio and video files, and is configured as follows:

[0028] Scan the directory where the audio and video files are stored to obtain the original paths of each audio and video file;

[0029] Remove redundant levels from the original path to obtain the storage paths for each of the multiple audio and video files. The redundant levels must include at least the device root directory level.

[0030] The technical scheme has the advantages or beneficial effects as follows: by cutting the redundant levels in the original path which at least contain the device root directory level, a simplified storage path is obtained, effectively eliminating the path information irrelevant to the audio and video file classification and attributes, reducing the interference when extracting the metadata field from the path subsequently, and improving the efficiency and accuracy of field extraction. Meanwhile, the simplified storage path focuses more on the actual classification level and identification information of the audio and video file, which not only facilitates the analysis of the hierarchical structure semantics in the path, but also better adapts to the metadata extraction needs of non-standard named files, and provides clear and high correlation path data support for subsequent structured object construction and same audio and video work identification, further optimizing the smoothness and reliability of the overall audio and video file metadata processing flow.

[0031] In a second aspect, the application further provides a poster data scraping method applied to the display device provided in various possible implementation manners of the first aspect, and the method comprises:

[0032] scanning a file directory where the audio and video files are stored to obtain a storage path of each of the plurality of audio and video files, the storage path comprising a folder name at a previous level and an audio and video file name at a last level;

[0033] extracting a metadata field of the audio and video file from the folder name and the audio and video file name to obtain a structured object of the audio and video file;

[0034] identifying the structured object of each of the plurality of audio and video files, and in the case that the plurality of audio and video files are identified as related files of a same audio and video work, merging network scraping requests of the plurality of audio and video files to initiate a preset number of network scraping requests, the preset number being less than the number of the plurality of audio and video files.

[0035] The technical scheme has the following advantages or beneficial effects: the metadata fields are extracted from the folder name and the audio / video file name to form a structured object by scanning the audio / video file storage path, the path hierarchy semantics are fully mined, the problem of non-standard naming files being difficult to accurately match is effectively solved, and the adaptability to non-standard naming scenarios is improved. Based on the core information in the structured object, related files of the same audio / video work are identified, the network scraping requests of the related files are merged, the number of network scraping request initiations is effectively reduced, the network transmission bandwidth occupation and server request pressure are reduced, and the response efficiency of the scraping request is improved. At the same time, with the help of path information extraction metadata and the same work identification mechanism, the accuracy and relevance of audio / video file metadata acquisition can be ensured, the problems of resource waste and redundant data caused by repeated scraping are improved, the metadata management process of multiple audio / video files is simplified, and the efficiency and practicability of the overall audio / video file metadata processing are improved.

[0036] In one of the embodiments, the folder name and the audio / video file name are subjected to field extraction to obtain metadata fields of the audio / video file, including:

[0037] The audio / video file name is taken as a current hierarchical object, the current hierarchical object is subjected to field extraction to obtain metadata fields in the current hierarchical object.

[0038] The last hierarchical folder name of the current hierarchical object is taken as a current hierarchical object, and the step of field extraction on the current hierarchical object is returned and continued to be executed until the current hierarchical object does not have a last hierarchical folder name.

[0039] The technical scheme has the following advantages or beneficial effects:

[0040] The metadata information contained in each level of the storage path is fully mined by adopting the way of gradually tracing back from the last level of the audio / video file name to the last hierarchical folder name, and the problem of metadata omission caused by single level extraction is improved. At the same time, the tracing back extraction logic can fully utilize the path hierarchy semantics, maximize the mining of scattered classification, year, technical parameter and other key information in the non-standard naming file path, effectively solve the defects of insufficient data integration capability of the prior art, provide more comprehensive and complete metadata support for subsequent structured object construction and same audio / video work identification, and further improve the comprehensiveness and accuracy of metadata processing in the complex path and non-standard naming scenarios.

[0041] In one of the embodiments, the current hierarchical object is subjected to field extraction to obtain metadata fields in the current hierarchical object, including:

[0042] The type corresponding naming rule template of the audio and video file is matched with the current hierarchical object, and in the case of successful matching, the metadata field in the current hierarchical object is obtained.

[0043] In the case of failed matching, based on the preset invalid field dictionary, the invalid field in the current hierarchical object is cleaned up; and based on the preset valid word dictionary, the current hierarchical object after cleaning is matched to obtain the metadata field in the current hierarchical object.

[0044] The technical solution has the following advantages or beneficial effects: by calling the naming rule template corresponding to the type of the audio and video file, the current hierarchical object is accurately matched to quickly extract the metadata field, and the efficiency and accuracy of metadata extraction in the standard naming scene are effectively improved. For the case of failed matching, the invalid field in the current hierarchical object is first cleaned up with the help of the preset invalid field dictionary, and then the metadata field is extracted by secondary matching with the preset valid word dictionary, which can solve the problems of insufficient data integration capability when parsing the file name and difficulty in parsing the semantics of non-standard naming file path, further expand the adaptation range of non-standard naming and complex format files, improve the situation of metadata extraction omission or misjudgment caused by non-standard naming, and ensure the consistency and reliability of metadata field extraction in different naming scenes, providing high-quality data support for subsequent identification of the same audio and video work and merging of network scraping requests, and comprehensively optimizing the overall effect of audio and video file metadata processing.

[0045] In one of the embodiments, before the metadata fields of the audio and video file are combined to obtain the structured object of the audio and video file, the following steps are further included:

[0046] In the case of extracting multiple same metadata fields and the multiple same metadata fields being derived from different levels in the storage path, based on the level distance between the source level and the last level of the metadata field, the metadata field with the smallest level distance is retained in the multiple same metadata fields.

[0047] The technical scheme has the following advantages or beneficial effects: for the scenario that multiple same-type metadata fields are extracted from different levels of storage paths, by taking the level distance between the source level of the metadata field and the last level (the level of the audio and video file name) as the basis for judgment, the metadata field corresponding to the minimum level distance is retained, which can accurately filter out metadata information that is strongly associated with the audio and video file and has a strong semantic fit, effectively improving the problem of metadata redundancy or judgment ambiguity caused by the coexistence of multiple levels of same-type fields. At the same time, this method does not require additional complex verification logic, and can achieve efficient deduplication and accurate filtering only by level distance, which not only guarantees the uniqueness and accuracy of the metadata field, but also provides high-quality data support for subsequent identification of the same audio and video work, merging of network scraping requests, and other processes, further optimizing the metadata processing effect in complex scenarios such as non-standard naming and multi-level paths, and improving the practicality and reliability of the overall technical solution.

[0091] It should be noted that the operating system can be a native operating system based on a specific operating platform, a third-party operating system deeply customized based on a specific operating platform, or an independent operating system specially developed for the display device.

[0092] The operating system can be divided into different modules or levels according to the functions implemented, for example, as shown in FIG. 2, in some embodiments, the system is divided into four layers, from top to bottom, an application layer (referred to as “application layer” for short), an application framework layer (referred to as “framework layer” for short), a system library layer, and a kernel layer.

In specific implementation, the application programs in the application layer are not limited to the above examples.

[0094] ​The framework layer provides an application programming interface (API) and a programming framework for applications. The application framework layer includes some pre-defined functions. The application framework layer is equivalent to a processing center that decides which application in the application layer to act.

[0096] In some embodiments, the activity manager is used to manage the life cycle of each application and the general navigation back function, such as controlling the exit, opening, back, etc. of the application. The window manager is used to manage all window programs, such as obtaining the size of the display screen, judging whether there is a status bar, locking the screen, intercepting the screen, controlling the display window change, for example, reducing the display window, shaking the display, twisting the display, etc.

[0097] In some embodiments, the system runtime library layer can provide support for the framework layer. When the framework layer is used, the operating system runs the instruction library included in the system runtime library layer, for example, the C / C++ instruction library, to realize the functions of the framework layer.

[0098] In some embodiments, the kernel layer is a functional layer between the hardware and the software of the display device 200. The kernel layer can realize the functions of hardware abstraction, multitasking, memory management, etc. For example, as shown in Figure 4As shown, the kernel layer can be configured with hardware drivers, and the kernel layer contains at least one of the following drivers: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor driver (such as fingerprint sensor, temperature sensor, pressure sensor, etc.), and power supply driver, etc.

[0099] It should be noted that the above examples are only a simple division of the operating system functions, and do not constitute a limitation on the specific operating system form of the display device 200 in the embodiments of the present application. According to the function of the display device, the type of the operating system, and other factors, the number and specific type of the levels contained in the operating system can be in other forms.

[0100] In combination with the foregoing principle, the embodiments of the present application provide a display device, comprising:

[0101] a display configured to display images and / or user interfaces;

[0102] a controller configured to:

[0103] scan a file directory in which audio and video files are stored to obtain a storage path of each of the audio and video files, the storage path including a folder name at a previous level and an audio and video file name at a last level;

[0104] extract a field from the folder name and the audio and video file name to obtain a metadata field of the audio and video file; and combine the metadata field of the audio and video file to obtain a structured object of the audio and video file;

[0105] identify the structured object of each of the audio and video files, and in a case where the audio and video files are identified as related files of a same audio and video work, merge network scraping requests of the audio and video files to initiate a preset number of network scraping requests, the preset number being less than a number of the audio and video files.

[0106] In some embodiments, a breadth-first scan can be performed on the file directory in which the audio and video files are stored. Specifically, all subdirectories can be scanned layer by layer, ensuring that the files in the same level directory are completely traversed before entering the next layer. A queue (Queue) is used to store the storage paths to be accessed, and each storage path is scanned one by one in accordance with the first-in first-out principle. The form of the storage path can be as follows: "NAS / storage / movies / 2023 / Earth_Extended_Dolby_4K_Blu-ray / Earth_Repaired.mkv". As can be seen, the storage path includes the audio and video file name at the last level, i.e. "Earth_Repaired.mkv", and also includes the files and names at the previous levels, such as "Earth_Extended_Dolby_4K_Blu-ray".

[0107] In some embodiments, when field extraction is performed on the folder name and the audio / video file name, the text data corresponding to the folder name and the audio / video file name can be processed based on an audio / video field-specific entity dictionary using a named entity recognition technology. The audio / video field-specific entity dictionary pre-collects standard terms, aliases, and format rules corresponding to target metadata fields such as film type, year format, resolution, audio encoding, and carrier format. After performing redundant character elimination, format standardization, and word segmentation preprocessing on the text data, a named entity recognition model incorporating the field-specific entity dictionary is used to perform entity recognition and field matching on the preprocessed text, locate and extract information corresponding to metadata fields such as film type, year, and technical parameters, and filter invalid data, mark missing fields, and remove duplicate information through preset rules, to finally obtain structured audio / video file metadata fields.

[0108] In some embodiments, when the metadata fields of the audio / video file are combined, the structured object can be combined from the field type and the field content. For example, structured object A: {type: movie; name: earth; year: null; resolution: 4K; audio: Dolby}. Null indicates a missing key field in the field extraction process, which is an automatic filling placeholder. In addition, if the extracted field has illegal characters, it can also be automatically replaced.

[0109] In some embodiments, when identification is performed based on the structured objects of the plurality of audio / video files, the key metadata fields representing the core identity of the audio / video work in each structured object can be extracted. The key metadata fields can at least include a work name field and a work type field. The work name field corresponds to the core identification name of the audio / video file, and the work type field corresponds to the image carrier category such as movie, TV series, animation, and documentary. By performing consistency comparison on the key metadata fields of the plurality of audio / video files, if the contents of the work name fields of different audio / video files are completely consistent and the contents of the work type fields are completely consistent, it is determined that the plurality of audio / video files are related files of the same audio / video work. At the same time, supplementary comparison can also be performed in combination with optional auxiliary verification fields (such as work year field and technical parameter field), to further improve the identification accuracy of the related files of the same work.

[0110] In some embodiments, when merging network scraping requests of multiple audio-video files, the identification information corresponding to the same audio-video work (such as the work name and work type in the key metadata field, or the combined identification formed by combining the work year) can be extracted, and the identification information is used as a unified scraping request parameter to replace the independent scraping request generated for each audio-video file. Through a preset request merging rule, a unified network scraping request for the same audio-video work is formed. The request can include all query conditions required to obtain the complete media metadata of the work, and only the unified scraping request is sent to the network scraping server to obtain the media metadata corresponding to the same work and synchronize to the multiple related audio-video files, thereby realizing the merging and optimization of the multiple file scraping requests.

[0111] In some embodiments, the preset number can be 1 or other numerical values.

[0112] The display device described above extracts metadata fields from the folder name and audio-video file name to form a structured object by scanning the audio-video file storage path, fully excavates the path hierarchical structure semantics, and effectively solves the problem of inaccurate matching of non-standard named files, thereby improving the adaptability to non-standard naming scenarios. Based on the core information in the structured object, the related files of the same audio-video work are identified, and the network scraping requests of the related files are merged, thereby effectively reducing the number of network scraping request initiations, reducing the network transmission bandwidth occupation and server request pressure, and improving the response efficiency of the scraping request. At the same time, with the help of path information extraction metadata and the same work identification mechanism, the accuracy and relevance of audio-video file metadata acquisition can be ensured, the problems of resource waste and redundant data caused by repeated scraping are improved, the metadata management process of multiple audio-video files is simplified, and the efficiency and practicality of the overall audio-video file metadata processing are improved.

[0113] In some embodiments, the controller performs field extraction on the folder name and the audio-video file name to obtain the metadata fields of the audio-video file, and is configured to:

[0114] The audio-video file name is used as the current hierarchical object, and field extraction is performed on the current hierarchical object to obtain the metadata fields in the current hierarchical object.

[0115] The folder name of the previous hierarchical object of the current hierarchical object is used as the current hierarchical object, and the step of field extraction on the current hierarchical object is returned and continued to be executed until the current hierarchical object does not have a previous hierarchical folder name.

[0116] In this embodiment, the metadata information contained in each level of the storage path is fully mined by gradually tracing back the folder names from the last level to the upper level, improving the metadata omission problem caused by single-level extraction. At the same time, the tracing back extraction logic can fully utilize the path level structure semantics to maximize the extraction of scattered classification, year, technical parameter and other key information in non-standard named file paths, effectively solving the defects of insufficient data integration capability of the prior art, providing more comprehensive and complete metadata support for subsequent structured object construction and same audio and video work recognition, and further improving the comprehensiveness and accuracy of metadata processing in complex path and non-standard naming scenarios.

[0117] In some embodiments, the controller performs field extraction on the current level object to obtain metadata fields in the current level object, which is configured to:

[0118] Call the naming rule template corresponding to the type of the audio and video file to match the current level object, and obtain the metadata fields in the current level object if the matching is successful;

[0119] If the matching fails, clean up the invalid fields in the current level object based on a preset invalid field dictionary; and match the cleaned current level object based on a preset valid word dictionary to obtain the metadata fields in the current level object.

[0120] In some embodiments, the naming rule template can be a predefined regular template.

[0121] In some embodiments, the naming format of the movie resource file can be "[name] [year] [cut version] [release note] [resolution] [video encoding] [sound effect mode] [audio encoding] [release group name]". Correspondingly, the specific movie file name can be:

[0122] Earth 2019 Blu-ray Remux 1080p AVC Atmos TrueHD7.1-OB

[0123] Wherein, the name is Earth, the year is 2019, the cut version is Blu-ray, the release note is Remux, the resolution is 1080P, the video encoding is AVC, the sound effect mode is Atmos, the audio encoding is TrueHD7.1, and the release group name is OB.

[0124] In some embodiments, the naming format of the television series resource file can be "[Chinese name] [name] [year] [S**E**] [release note] [resolution] [source] [audio encoding] [video encoding] [release group name]". Correspondingly, the specific television series file name can be:

[0125] Moon Story S04E01 PROPER 720p HDTV x264-CTU

[0126] The Chinese title is "Moon Story," S04 indicates the fourth season, E01 indicates the episode number, and the release description is "PROPER," meaning an optimized version. The resolution is 720P, the source is HDTV, the video encoding is x264, and the release group is CTU.

[0127] Understandably, when the naming of audio and video files is known, metadata fields can be directly extracted using regular expression templates.

[0128] In some embodiments, the filename may also appear as follows:

[0129] XXXXX / TV series title XXXX / S02E01.mp4

[0130] XXXXX / TV series title XXXX / Season 1.mp4

[0131] XXXXX / TV series title XXXX / Season 01.mp4

[0132] XXXXX / TV series title XXXX / 1x02.mp4

[0133] XXXXX / TV series title XXXX / E01.mp4

[0134] XXXXX / TV series title XXXX / EP1.mp4

[0135] XXXXX / TV series title XXXX / pure numbers.mp4

[0136] XXXXX / TV series title XXXX / Episode X.mp4

[0137] XXXXX / TV series title XXXX / Season X, Episode XX.mp4

[0138] XXXXX / TV series title XXXX / Part IV.mp4

[0139] XXXXX / TV series title XXXX / E12.mp4

[0140] In some embodiments, the preset invalid field dictionary may include edited, abridged, repaired, or extended versions. In some embodiments, the preset valid word dictionary may include Simplified Chinese, audio tracks, bilingual, HD, Dolby, DTS, etc.

[0141] In the embodiment, by calling the naming rule template corresponding to the audio and video file type, the metadata field is quickly extracted by accurately matching the current hierarchical object, and the efficiency and accuracy of metadata extraction in the standard naming scenario are effectively improved. For the case of failed matching, the invalid fields in the current hierarchical object are first cleaned by means of the preset invalid field dictionary, and then the metadata field is extracted by secondary matching through the preset valid word dictionary, which can solve the problems of insufficient data integration capability when parsing the file name and difficulty in parsing the semantics of non-standard named file path, further expand the adaptation range of non-standard named and complex format files, improve the situation of metadata extraction omission or misjudgment caused by non-standard naming, and ensure the consistency and reliability of metadata field extraction in different naming scenarios, providing high-quality data support for subsequent identification of the same audio and video works and merging of network scraping requests, and optimizing the overall effect of audio and video file metadata processing.

[0142] In some embodiments, before the controller combines the metadata fields of the audio and video file to obtain the structured object of the audio and video file, it is further configured to:

[0143] In the case that multiple metadata fields of the same type are extracted and the multiple metadata fields of the same type are derived from different levels in the storage path, based on the level distance between the source level and the last level of the metadata field, the metadata field corresponding to the minimum level distance is retained in the multiple same metadata fields.

[0144] For example, when extracting the metadata field, multiple metadata fields of the name type are obtained. Among them, the content of one metadata field is "Earth", and the source level is the last level of the audio and video file name. And the content of another metadata field is "Globe", and the source level is the folder name of the third last level. It can be seen that the level distance between the source level and the last level of "Earth" is 0, and the level distance between the source level and the last level of "Globe" is 3. Therefore, the metadata field "Earth" corresponding to the minimum level distance can be retained, that is, the name of the audio and video can be determined as "Earth".

[0145] In some embodiments, if no valid content is extracted when extracting the metadata field of the name type, the metadata field of the name type can be directly supplemented first, such as being filled into the structured object first, and then the same type of metadata field is extracted, and the above processing mode based on the level distance can be used again.

[0146] In this embodiment, for the scenario that multiple same-type metadata fields may be extracted for different levels of storage paths, by taking the level distance between the source level of the metadata field and the last level (the level of the audio / video file name) as the basis for judgment, the metadata field corresponding to the minimum level distance is retained, which can accurately filter out metadata information with strong association with audio / video files and semantic fit, effectively improving the problems caused by metadata redundancy or judgment ambiguity caused by the coexistence of multiple levels of same-type fields. At the same time, this method does not require additional complex verification logic, and can achieve efficient deduplication and accurate filtering only by level distance, which not only guarantees the uniqueness and accuracy of the metadata field, but also provides high-quality data support for subsequent identification of the same audio / video work, merging of network scraping requests, and other processes, further optimizing the metadata processing effect in complex scenarios such as non-standard naming and multi-level paths, and improving the practicality and reliability of the overall technical solution.

[0147] In some embodiments, the metadata fields include audio / video titles and audio / video names; the controller performs identification based on the structured objects of the plurality of audio / video files, and is configured to:

[0148] In the case where the audio / video name and the audio / video type are the same between different structured objects, the corresponding different audio / video files are identified as related files of the same audio / video work.

[0149] For example, for the same scanning task, the structured object of the previously scanned audio / video file is obtained as A: {type: movie; name: earth; year: 2023; resolution: 4K; audio: Dolby; path: xxx} through the above process.

[0150] Then another video path is found in the process of continuing to perform scanning: / movie / 2023 / lost earth extended version Dolby 4K Blu-ray / bonus behind the scenes.mkv. The above process is performed on the corresponding audio / video file of the video path, and the structured object B: {type: movie; name: earth; year: 2023; resolution: null; audio: null; path: xxx} is obtained.

[0151] According to the above identification logic, because the name is "earth" and the type is "movie", it can be determined that the video file corresponding to structured object A and the video file corresponding to structured object B are related files of the same audio / video work.

[0152] In the embodiment, the audio and video name and the audio and video type are taken as the identification basis of the same audio and video work, and the consistency of the two fields in different structured objects is determined to identify the related files of the same work, which can effectively solve the misjudgment problem of the prior art to the multi-fragment files in the complex format of the Blu-ray disc, and avoid the repeated scraping caused by the misjudgment of the fragment files of the same work as independent files. At the same time, the identification method does not depend on complex additional verification logic, can quickly associate the audio and video files with non-standard naming but consistent core information, further improves the adaptability to the non-standard naming scene, lays a reliable foundation for subsequent merging of network scraping requests, reduces network dependence, improves scraping efficiency, and guarantees the association and efficiency of audio and video file metadata processing in multiple scenes.

[0153] In some embodiments, the controller performs scanning on a file directory where the audio and video files are stored to obtain a storage path of each of the plurality of audio and video files, and is configured to:

[0154] scanning a file directory where the audio and video files are stored to obtain an original path of each of the plurality of audio and video files;

[0155] cutting the redundant levels in the original path to obtain a storage path of each of the plurality of audio and video files, and the redundant levels at least include a device root directory level.

[0156] In some embodiments, the original path refers to the complete location address where the file is actually stored in the storage device (hard disk, USB flash disk, server, etc.), which can accurately locate the "root directory + each level of folder + file name (including suffix)" of the file.

[0157] For example, the original path can be "NAS / storage / movies / 2023 / Earth_Extended_Dolby_4K_Blu-ray / Earth_Repaired.mkv". Among them, "NAS" is the device root directory level, and it can be seen that the folder name of this level is redundant for the previous extraction process. In addition, it can also be seen that "storage" is also a redundant level. In actual implementation, the redundant level dictionary can be called to determine the redundant level.

[0158] In this embodiment, by pruning the redundant levels in the original path that at least contain the device root directory level, a simplified storage path is obtained, effectively eliminating path information irrelevant to audio and video file classification and attributes, reducing interference when extracting metadata fields from the path subsequently, and improving the efficiency and accuracy of field extraction. At the same time, the simplified storage path focuses more on the actual classification level and identification information of the audio and video file, which not only facilitates the parsing of the hierarchical structure semantics in the path, but also better adapts to the metadata extraction needs of non-standard named files, and provides clear and high correlation path data support for subsequent structured object construction and same audio and video work identification, further optimizing the smoothness and reliability of the overall audio and video file metadata processing flow.

[0159] The above is mainly to illustrate the display device, in an exemplary embodiment, a poster data scraping method is also provided, applied to the aforementioned display device. Referring to Figure 5 The method comprises:

[0160] 502, scanning the file directory where the audio and video files are stored to obtain the storage path of each audio and video file, the storage path comprising the folder name of the previous level and the audio and video file name of the last level;

[0161] 504, field extraction is performed on the folder name and the audio and video file name to obtain the metadata field of the audio and video file; the metadata field of the audio and video file is combined to obtain a structured object of the audio and video file;

[0162] 506, based on the structured object of each audio and video file, identification is performed, and in the case where the plurality of audio and video files are identified as related files of the same audio and video work, the network scraping requests of the plurality of audio and video files are merged to initiate a preset number of network scraping requests, the preset number being less than the number of the plurality of audio and video files.

[0163] In some embodiments, the field extraction on the folder name and the audio and video file name to obtain the metadata field of the audio and video file comprises:

[0164] The audio and video file name is taken as a current level object, field extraction is performed on the current level object to obtain the metadata field in the current level object;

[0165] The folder name of the previous level of the current level object is taken as the current level object, and the step of field extraction on the current level object is returned and continued to be executed until the current level object does not have the folder name of the previous level.

[0166] In some embodiments, the field extraction on the current level object to obtain the metadata field in the current level object comprises:

[0167] The type of the called audio and video file is matched with the naming rule template corresponding to the current hierarchical object, and in the case of successful matching, the metadata field in the current hierarchical object is obtained;

[0168] In the case of failed matching, the invalid field in the current hierarchical object is cleaned based on the preset invalid field dictionary, and the cleaned current hierarchical object is matched based on the preset valid word dictionary to obtain the metadata field in the current hierarchical object.

[0169] In some embodiments, before the metadata field of the audio and video file is combined to obtain the structured object of the audio and video file, the method further comprises:

[0170] In the case that multiple same metadata fields are extracted and the multiple same metadata fields are derived from different levels in the storage path, based on the level distance between the source level and the last level of the metadata field, the metadata field with the minimum level distance is reserved in the multiple same metadata fields.

[0171] In some embodiments, the overall interaction process of the above poster scratching process can refer to Figure 6 In some embodiments, the process of scanning the file directory where the audio and video file is stored can refer to Figure 7 .

[0172] Figure 7 The directory structure under the BDMV folder can be as follows:

[0173] ├── BDMV

[0174] │ ├── AUXDATA

[0175] │ ├── BACKUP

[0176] │ ├── BDJO

[0181] │ ├── STREAM

[0182] │ ├── index.bdmv

[0183] │ └── MovieObject.bdmv

[0184] └── CERTIFICATE

[0185] If a directory structure contains a STREAM folder, an index.bdmv file, and a MovieObject.bdmv folder, then the directory structure can be considered a BDMV structure.

[0186] For example, the directory structure of other complex format A videos can be as follows:

[0187] ├─ index.bdmv

[0188] ├─ ProductProof

[0189] ├─ Publication Declare

[0190] │ publicationDeclare.json

[0201] If a directory structure contains an index.bdmv file, a ProductProof folder, a PublicationDeclare folder, and a Resource folder, then the directory structure can be considered to be in format A.

The display device according to claim 1, characterized in that, The metadata fields include audio / video titles and audio / video names; the controller performs identification based on the structured objects of the multiple audio / video files, and is configured as follows: When different structured objects have the same audio and video names and types, the corresponding different audio and video files are identified as related files of the same audio and video work.

6. The display device according to claim 1, characterized in that, The controller performs a scan of the file directories where the audio and video files are stored, obtains the storage paths of the various audio and video files, and is configured as follows: Scan the directory where the audio and video files are stored to obtain the original paths of each audio and video file; By trimming redundant levels in the original path, storage paths for multiple audio and video files are obtained, wherein the redundant levels include at least the device root directory level.

7. A method for scraping poster data, characterized in that, Applied to the display device as described in any one of claims 1-6; The method includes: The file directory where the audio and video files are stored is scanned to obtain the storage paths of multiple audio and video files. The storage paths include the folder names at the previous level and the audio and video file names at the last level. Extract fields from the folder name and the audio / video file name to obtain the metadata fields of the audio / video file; combine the metadata fields of the audio / video file to obtain the structured object of the audio / video file; Based on the structured objects of the multiple audio and video files, if the multiple audio and video files are identified as related files of the same audio and video work, the network scraping requests of the multiple audio and video files are merged to initiate a preset number of network scraping requests, the preset number being less than the number of the multiple audio and video files.

8. The method according to claim 7, characterized in that, The step of extracting fields from the folder name and the audio / video file name to obtain the metadata fields of the audio / video files includes: The audio and video file names are used as the current level object. Fields are extracted from the current level object to obtain the metadata fields in the current level object. The parent folder name of the current level object is used as the current level object, and the steps for extracting fields from the current level object are returned and execution continues until the current level object does not have a parent folder name.

9. The method according to claim 8, characterized in that, The step of extracting fields from the current-level object to obtain the metadata fields in the current-level object includes: The naming rule template corresponding to the type of the audio / video file is called and matched with the current layer object. If the match is successful, the metadata field in the current layer object is obtained. In the event of a failed match, invalid fields in the current level object are cleaned based on a preset invalid field dictionary; the cleaned current level object is then matched based on a preset valid word dictionary to obtain the metadata fields in the current level object.

10. The method according to claim 7, characterized in that, Before combining the metadata fields of the audio and video files to obtain the structured object of the audio and video files, the method further includes: If multiple identical metadata fields are extracted and these fields originate from different levels in the storage path, the metadata field with the smallest level distance is retained among the multiple identical metadata fields based on the level distance between the source level and the last level of the metadata field.
