Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a frame switching method, device, equipment and computer-readable medium. Background Art

[0002] This section is intended to provide a background or context to the embodiments of the application that are recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.

[0003] In the field of digital content creation and distribution, with the popularization of mobile devices and diversified display platforms, the smooth switching of special effects materials between different frames has become a key issue that needs to be solved urgently.

[0004] Traditional frame switching technologies mostly rely on overall update strategies. For example, when the user interface switches from landscape to portrait, the system needs to completely unload the current material package and reload a set of material packages optimized for the new frame. This process involves a comprehensive reload of resources such as pictures, audio and video, and keyframe animations, which not only consumes a lot of computing resources and time, but also significantly increases memory usage, causing application freezes or even crashes, especially on mobile devices with limited resources.

[0005] In view of the above problems, it is necessary to provide a technical solution for frame switching with higher switching efficiency and fluency. Summary of the invention

[0006] Multiple aspects of the present application provide a frame switching method, device, equipment and computer-readable storage medium to improve the efficiency and smoothness of frame switching.

[0008] In response to an image frame switching instruction for target digital content, determining a target image frame to be displayed;

[0009] Reading differential resources related to the target frame from the multi-frame material package corresponding to the target digital content, wherein the multi-frame material package includes all content resources supporting displaying the target digital content in multiple frames, and the content resources include common resources for multiple frames and differential resources for a single frame;

[0010] The difference resource related to the target frame is loaded according to the incremental loading mechanism, so as to switch the target digital content to the target frame for display.

[0011] Another aspect of the present application provides a frame switching device, wherein the device comprises:

[0012] A target frame determination module, configured to determine a target frame to be displayed in response to a frame switching instruction for target digital content;

[0013] A difference resource reading module, used for reading difference resources related to the target frame from the multi-frame material package corresponding to the target digital content, wherein the multi-frame material package includes all content resources supporting display of the target digital content in multiple frames, and the content resources include common resources for multiple frames and difference resources for a single frame;

[0014] The difference resource loading module is used to load the difference resource related to the target frame according to the incremental loading mechanism, so as to switch the target digital content to the target frame for display.

[0015] Another aspect of the present application provides an electronic device, the electronic device comprising:

[0016] at least one processor; and

[0017] a memory communicatively connected to the at least one processor; wherein,

[0018] The memory stores instructions that can be executed by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can perform the frame switching method as described above.

[0019] In another aspect of the present application, a computer-readable storage medium is provided, on which computer program instructions are stored. The computer program instructions can be executed by a processor to implement the frame switching method as described above.

[0020] In the solution provided by the embodiment of the present application, by responding to the frame switching instruction for the target digital content, the target frame to be displayed is determined, and then the difference resources related to the target frame are read from the multi-frame material package corresponding to the target digital content, wherein the multi-frame material package includes all content resources that support displaying the target digital content in multiple frames, and the content resources include common resources for multiple frames and difference resources for a single frame. Then, the difference resources related to the target frame are loaded according to the incremental loading mechanism, so that the target digital content can be switched to the target frame for display. Compared with the prior art that requires completely unloading the current material package and reloading a complete set of material packages when switching frames, the technical solution of the present application only needs to load the difference resources to achieve fast frame switching. Since only the difference resources required for the target frame are loaded instead of the whole set of materials, the computing resource consumption and memory occupation can be effectively reduced, and the application freeze problem caused by resource overloading can be avoided. Moreover, by reducing the amount of loaded resources, the frame switching efficiency can be effectively improved, thereby improving the smooth experience of users when switching between different frames.

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] In a typical configuration of the present application, the terminal and the equipment of the service network each include one or more processors (CPU), input / output interface, network interface and memory.

[0032] The memory may include non-permanent storage in a computer-readable medium, random access memory (RAM) and / or non-volatile memory in the form of read-only memory (ROM) or flash RAM. The memory is an example of a computer-readable medium.

[0033] Computer readable media include permanent and non-permanent, removable and non-removable media, and can be implemented by any method or technology to store information. Information can be computer program instructions, data structures, modules of programs or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technology, read-only compact disk (CD-ROM), digital versatile disk (DVD) or other optical storage, magnetic cassettes, magnetic tape disk storage or other magnetic storage devices or any other non-transmission media that can be used to store information that can be accessed by a computing device.

[0034] In view of the problem of low efficiency and poor fluency in the prior art that the current material package needs to be completely unloaded and a complete set of material packages needs to be reloaded when switching frames, the embodiments of the present application provide a frame switching method, device, equipment and computer-readable storage medium to improve the efficiency and fluency of frame switching, which determines the target frame to be displayed in response to the frame switching instruction for the target digital content, and then reads the difference resources related to the target frame from the multi-frame material package corresponding to the target digital content, wherein the multi-frame material package includes all content resources that support displaying the target digital content in multiple frames, and the content resources include common resources for multiple frames and common resources for single frame. The target digital content can be switched to the target frame for display by loading the differential resources used, and then loading the differential resources related to the target frame according to the incremental loading mechanism. Compared with the prior art that requires completely unloading the current material package and reloading a complete set of material packages when switching frames, the technical solution of the present application only needs to load differential resources to achieve fast frame switching. Since only the differential resources required for the target frame are loaded instead of the entire set of materials, the computing resource consumption and memory usage can be effectively reduced, and the application freeze problem caused by resource overloading can be avoided. In addition, the frame switching efficiency can be effectively improved by reducing the amount of loaded resources, thereby improving the smooth experience of users when switching between different frames.

[0035] The following is an exemplary description of the frame switching method, device, equipment and computer-readable storage medium provided in the present application.

[0036] In actual scenarios, the execution subject of the frame switching method provided in the embodiment of the present application can be a user device, or a device formed by integrating a user device and a network device through a network, or an application (such as a rendering engine, system software, etc.) running on the above device. The user device includes but is not limited to various terminal devices such as computers, mobile phones, tablet computers, smart watches, and bracelets. The network device includes but is not limited to network hosts, single network servers, multiple network server sets, or cloud computing-based computer sets. Here, the cloud is composed of a large number of hosts or network servers based on cloud computing (Cloud Computing), where cloud computing is a type of distributed computing, a virtual computer composed of a group of loosely coupled computer sets.

[0037] Figure 1 The processing flow of a frame switching method provided by an embodiment of the present application is shown, and the method at least includes the following processing steps:

[0038] Step S101 : In response to an image frame switching instruction for target digital content, a target image frame to be displayed is determined.

[0039] Among them, the target digital content can be any digital content that can be displayed through multiple frames, including but not limited to visual effects (such as video effects, game effects, photography effects, etc.), applications, web pages, games, etc. The above digital content can all achieve a more efficient and smooth multi-frame switching effect based on the technical solution provided in the embodiments of the present application.

[0040] The above-mentioned frame switching instruction can be triggered when a display environment change is detected. The display environment change refers to a change in the screen orientation, resolution or size of the user device, which requires adaptive adjustment of the content being displayed. The above-mentioned display environment changes may include but are not limited to screen rotation (from landscape to portrait or vice versa), resolution change, window size adjustment, display ratio adjustment, and device sensor feedback. When these changes are detected, the system will trigger the frame switching instruction.

[0041] After detecting the above-mentioned frame switching instruction, it is necessary to determine the target frame to be displayed, that is, to determine which frame to switch to for display. Specifically, the target frame to be displayed can be determined by the following steps: first, identify the current display environment information, confirm the screen orientation (landscape or portrait), resolution and any factors that may affect the layout of the current device, such as screen size and other display environment information, and parse the frame switching instruction to understand the user or system's instruction intention. For example, the user may issue a switching instruction through gesture operation (such as rotating the device) or menu selection, and then determine the target frame to be displayed by searching the frame configuration information according to the current display environment information and the requirements of the frame switching instruction. Among them, pre-defined layout rules or style sheets can be used to match the most suitable frame layout, that is, the target frame.

[0042] Step S102, reading differential resources related to the target frame from the multi-frame material package corresponding to the target digital content, wherein the multi-frame material package includes all content resources that support displaying the target digital content in multiple frames, and the content resources include common resources for multiple frames and differential resources for a single frame.

[0043] Among them, the above-mentioned multi-frame material package is a collection of content resources that support multiple frame displays, including all images, videos and other multimedia content required to support different display environments (such as horizontal screen, vertical screen, etc.), which can help content creators efficiently cover multiple platforms and devices, and ensure that the display effects under different frames are consistent and high-quality. The multi-frame material package of the embodiment of the present application realizes efficient and smooth frame switching through an incremental loading mechanism, ensuring the consistency and high quality of content display under different display conditions.

[0044] The above-mentioned content resources refer to various materials used in the process of digital content creation and distribution, including but not limited to multimedia elements such as images, videos, and audio. In order to meet the multi-frame display requirements of the target digital content, the embodiment of the present application needs to determine the content resources required for each of the multiple frames, so as to obtain all content resources that can meet the multi-frame display requirements. In order to realize the cross-frame reuse of content resources, it is necessary to classify all content resources according to the characteristics of whether they can be reused. For example, the content resources that can be reused are classified as common resources, and the content resources that cannot be reused are classified as differential resources.

[0045] Among them, public resources can be shared between different frames, and only one copy is needed, without the need to prepare a separate copy for each frame. For example, some audio files or common background elements may be the same in different frames, so only one copy is needed. Differential resources are customized to adapt to specific frames. For example, the picture sizes of horizontal and vertical screens are different, and designers need to provide different picture versions for these two frames.

[0046] Since the above-mentioned step S101 is executed under the trigger of the frame switching instruction, it means that before step S101, the target digital content has been loaded and displayed through the historical frame. Since the public resources are shared by the historical frame and the target frame, based on the technical concept of public resource reuse and incremental loading of the present application, the public resources can be directly reused without repeated reading and loading. Only the difference resources need to be read and loaded. In this way, when switching the frame, only the difference resources related to the new frame need to be loaded without reloading all resources, thereby effectively improving the loading efficiency and the smoothness of the display.

[0047] Step S103: loading the difference resources related to the target frame according to the incremental loading mechanism, so as to switch the target digital content to the target frame for display.

[0048] The incremental loading mechanism is a data loading technology proposed to improve the efficiency of data synchronization and updating. This mechanism allows the system to load only the data that has been changed since the last update, rather than loading the entire data set each time, which can significantly reduce the time and resource consumption of data processing. The embodiment of the present application applies the idea of ​​incremental loading to the specific scene switching of the present application. Combined with the above steps, it can achieve the purpose of reducing the amount of resource reloading and improving the efficiency and smoothness of scene switching.

[0049] The above-mentioned frame switching method provided in the embodiment of the present application determines the target frame to be displayed by responding to the frame switching instruction for the target digital content, and then reads the difference resources related to the target frame from the multi-frame material package corresponding to the target digital content, wherein the multi-frame material package includes all content resources that support displaying the target digital content in multiple frames, and the content resources include common resources for multiple frames and difference resources for a single frame. Then, the difference resources related to the target frame are loaded according to the incremental loading mechanism, so that the target digital content can be switched to the target frame for display. Compared with the prior art that needs to completely unload the current material package and reload a complete set of material packages when switching frames, the technical solution of the present application only needs to load the difference resources to achieve fast frame switching. Since only the difference resources required for the target frame are loaded instead of the whole set of materials, the computing resource consumption and memory occupation can be effectively reduced, and the application freeze problem caused by resource overloading can be avoided. Moreover, by reducing the amount of loaded resources, the frame switching efficiency can be effectively improved, thereby improving the smooth experience of users when switching between different frames.

[0050] In some modified implementations, the multi-frame material package further includes a frame resource description file, and the frame resource description file records frame resource reference information between frames and content resources;

[0051] The above step S102 of reading the difference resources related to the target frame from the multi-frame material package corresponding to the target digital content may include:

[0052] According to the frame resource reference information recorded in the frame resource description file, the difference resource having a reference relationship with the target frame is read from the multi-frame material package corresponding to the target digital content.

[0053] In this embodiment, a multi-frame material package may include a frame resource description file and all content resources that support displaying target digital content in multiple frames, wherein the frame resource description file records frame resource reference information between frames and content resources, and the frame resource reference information refers to information that describes the reference relationship between frames and content resources. The embodiment of the present application uses a reference method to realize the association between frames and content resources, and then based on the reference relationship, when a certain frame needs to be displayed, the referenced content resources are directly called for loading and display. Based on this technical concept, when making a material package, all content resources can be added to a total material package without having to make corresponding material packages for each frame separately, thereby simplifying the production steps of the material package, and being able to achieve efficient reuse of public resources across frames, reducing the workload of designers, improving the production efficiency of material packages and reducing production costs, and later maintenance only needs to maintain individual content resources and reference information in the material package, so it can also effectively improve maintenance efficiency and reduce maintenance costs.

[0054] When this embodiment is implemented, it is possible to determine which content resources are related to the target frame according to the frame resource reference information in the frame resource description file, and only the difference resources therein need to be read and loaded.

[0055] In this embodiment, by introducing the frame resource description file and the frame resource reference information to manage the content resources and associate them with the frame, it can ensure that when the frame needs to be switched, the content resources related to the target frame can be directly located according to the reference information in the frame resource description file, thereby improving the positioning and reading efficiency of the content resources, and helping to improve the efficiency and fluency of frame switching. Moreover, by introducing the frame resource description file and the frame resource reference information, content management becomes simpler. Users can quickly understand the status of each frame and the relationship with the content resources by viewing the frame resource description file, making it easier to perform version control and resource management. In addition, by clearly recording the reference relationship between the frame and the resource, it can be ensured that no related resources will be missed during the update process, which helps to maintain the consistency and integrity of the data and avoid problems caused by missing certain resources. In addition, when it is necessary to add a new frame or modify an existing frame, it is only necessary to update the frame resource description file and add the updated content resources to the multi-frame material package. This flexibility makes it easier for the system to adapt to future changes in demand and simplifies maintenance.

[0056] Based on the above implementation, in some modified implementations, the multi-frame material package includes multiple frame resource description files, and each frame resource description file records frame resource reference information corresponding to a frame;

[0057] The multi-frame resource package also includes an entry file, wherein the entry file records the correspondence between multiple frames and multiple frame resource description files in the multi-frame material package;

[0058] The step of reading, according to the frame resource reference information recorded in the frame resource description file, the difference resource having a reference relationship with the target frame from the multi-frame material package corresponding to the target digital content includes:

[0059] Querying a frame resource description file corresponding to the target frame according to the entry file;

[0060] According to the frame resource reference information recorded in the frame resource description file obtained by querying, the difference resource having a reference relationship with the target frame is read from the multi-frame material package corresponding to the target digital content.

[0061] In this embodiment, the multi-frame material package not only includes multiple frame resource description files and all content resources, but also includes an entry file. Such a design can further improve the efficiency and flexibility of frame switching. Specifically, since each frame resource description file records the frame resource reference information of a specific frame, the frame and the frame resource description file are one-to-one corresponding. For each frame (such as an image of different resolution or size), there is an independent file to describe all the relevant content resources and their locations required for it. This structure allows the system to independently handle the resource dependencies for each frame.

[0062] The role of the entry file is to record the correspondence between all frames and their respective frame resource description files. It can be regarded as an index of a multi-frame material package to help the system quickly locate the frame resource description file required for a specific frame.

[0063] Based on the above entry file and multiple frame resource description files, the frame resource description file corresponding to the target frame can be found according to the entry file. Once the correct frame resource description file is found, the difference resources that have a reference relationship with the target frame can be located and read according to the frame resource reference information recorded therein.

[0064] Through this implementation, for each frame, the loading of the required resources can be controlled very accurately. When the client software needs to load the resources of a specific frame, it can directly read the description file corresponding to the frame, so as to quickly find and load the required resources, which effectively simplifies the resource loading process. There is no need to process the information of multiple frames, only the description file of the currently required frame needs to be processed. In addition, when the resources of a certain frame change, only the description file of the corresponding frame needs to be updated without affecting the description files of other frames, which is convenient for maintenance and updating.

[0065] In addition, by introducing the entry file, the organizational structure of the material package becomes clearer and easier to manage and maintain. At the same time, the entry file serves as a navigation directory, so that the rendering engine can quickly and accurately find the required frame resource description file according to the entry file, avoiding the process of traversing the entire material package to find the resource description file, thereby improving loading efficiency and reducing user waiting time. In addition, by concentrating the information of all frame resource description files in one entry file, the resources of the entire material package can be managed more efficiently, which is particularly beneficial for large-scale projects or scenes that require frequent updates. It is particularly suitable for application scenarios that require frequent updates and management of multiple versions of resources. It can not only improve the speed of data processing, but also reduce the demand for storage space while ensuring data consistency and integrity. For example, developers or maintenance personnel can quickly understand the overall structure of the material package by viewing the entry file, and it is easier to find the reuse of resources, which helps to further optimize the resource management strategy. In addition, the existence of the entry file makes the maintenance and update of the material package more convenient. When you need to add or delete frames, you only need to update the information in the entry file without manually adjusting the position of each frame resource description file. For example, if you need to add a new frame, you only need to add a new record in the entry file and create a corresponding frame resource description file without modifying the location information of other files.

[0066] Based on the aforementioned implementation manner, in other modified implementation manners, the multi-frame material package includes a frame resource description file, and the frame resource description file is an entry file of the multi-frame material package, and the frame resource reference information corresponding to the multiple frames is recorded in the file;

[0067] The step of reading, according to the frame resource reference information recorded in the frame resource description file, the difference resource having a reference relationship with the target frame from the multi-frame material package corresponding to the target digital content includes:

[0068] Querying the frame resource reference information corresponding to the target frame in the frame resource description file;

[0069] According to the retrieved frame resource reference information, the difference resource having a reference relationship with the target frame is read from the multi-frame material package corresponding to the target digital content.

[0070] In this implementation, all frames and their resource reference information are concentrated in a total frame resource description file. The aggregated frame resource description file serves as an entry file and acts as a navigation directory for the material package, so that the rendering engine can quickly locate the resource description information required for a specific frame, which is conducive to unified management and maintenance. In addition, regardless of the frame, all resource dependencies will be found in this single frame resource description file. The advantage of this is that it can simplify the file management and query process because there is no need to maintain multiple description files and additional entry files.

[0071] When a specific target frame needs to be processed, it will directly search for resource reference information related to the target frame in the frame resource description file. After finding the corresponding reference information, it can accurately read the difference resources associated with the target frame in the multi-frame material package based on this information. The advantage of this implementation method is its simplicity, which reduces the number and complexity of files and simplifies the query logic. However, this also requires that the frame resource description file itself must be powerful and flexible enough to clearly record the resource requirements of each frame, so as to facilitate efficient resource retrieval and loading. This implementation method is suitable for application scenarios that require unified management of multiple frame resources, especially when these frames share similar resources or the resource reference information does not change frequently. This approach can improve the response speed of the system and is easy to maintain.

[0072] Based on any of the foregoing implementations, in some modified implementations, the frame resource reference information includes annotation information of the content resource referenced by the target frame, and the annotation information includes an identifier and a reusability identifier of the content resource;

[0073] The step of reading, according to the frame resource reference information recorded in the frame resource description file, the difference resource having a reference relationship with the target frame from the multi-frame material package corresponding to the target digital content includes:

[0074] Determine, according to the frame resource reference information recorded in the frame resource description file, the annotation information of all content resources referenced by the target frame;

[0075] According to the reusability identifier, identifying the annotation information of the difference resource used by the target frame from the annotation information of all the content resources;

[0076] According to the identified annotation information of the difference resource, the difference resource having a reference relationship with the target frame is read from the multi-frame material package corresponding to the target digital content.

[0077] This embodiment further refines the information content in the frame resource description file and introduces the concept of annotation information, which refers to some additional information related to the content resources recorded in the frame resource description file. This information is used to help the system understand and process resources, especially to determine which resources are required for a specific frame and whether these resources can be reused. Among them, in addition to the identifier and reusability identifier of the content resource, the annotation information may also include at least one information such as resource path, resource type, and applicable frame. The above annotation information is explained below.

[0078] An identifier is a unique code or name assigned to each content resource, which is used to uniquely identify the resource. An identifier can be a string or a number, ensuring that each content resource will not be confused with other content resources in the entire material package. Through the identifier, the rendering engine can quickly locate a specific resource in the frame resource description file and load the corresponding file as needed.

[0079] The resource path refers to the specific location of the content resource in the material package, usually a file system path or a relative path, which is used to instruct the rendering engine how to find and load a specific resource. The path information enables the rendering engine to accurately extract the required resources from the material package based on the reference information in the description file.

[0080] Resource type refers to the specific type of content resource, such as image (JPEG, PNG), video (MP4, AVI), audio (MP3, WAV), etc. Resource type information is used to tell the rendering engine how to handle specific resources. For example, image files may need to be decoded and displayed, while audio files need to be played.

[0081] Applicable aspect ratio refers to the aspect ratio that the content resource is suitable for, such as 16:9 (widescreen), 9:16 (vertical screen), 4:3 (standard screen), etc. Applicable aspect ratio information can help the rendering engine determine when and how to use specific resources. For example, a picture suitable for 16:9 aspect ratio may not be loaded in 9:16 aspect ratio.

[0082] The reusability mark is a mark or label that indicates whether a content resource can be used in different frames. When a resource is marked as a public resource, it means that it can be used in multiple frames and there is no need to prepare a separate copy for each frame. On the contrary, if the resource is not a public resource, it means that it is designed specifically for a specific frame and cannot be used in other frames.

[0083] When the system needs to process a specific target frame, it will first determine the annotation information of all content resources referenced by the target frame based on the information in the frame resource description file, and obtain the identifiers and reusability flags of these resources; then, the system will check the reusability flags of these content resources to determine which resources are differential resources specifically for the target frame. For example, if the reusability flag of a content resource that has a reference relationship with the target frame is "false", it means that the content resource is specific to the target frame and needs to be loaded; then, based on the resource path and other information in the annotation information of the identified differential resources, these differential resources that have a reference relationship with the target frame are located and read from the multi-frame material package.

[0084] This implementation, by introducing annotation information, not only helps to more accurately manage the specific content resources required for each frame, avoiding loading unnecessary data, but also enables the same common resources to be shared between different frames through reusability identification, which can effectively reduce the demand for storage space. In summary, through this implementation, more precise control and management of frame resources can be achieved, which helps to improve system performance and optimize resource utilization.

[0085] Based on any of the foregoing implementations, in some modified implementations, loading the difference resource related to the target frame according to the incremental loading mechanism to switch the target digital content to the target frame for display includes:

[0086] While retaining the loaded common resources, the loaded difference resources applicable to the historical frame are removed, and the newly read difference resources related to the target frame are loaded, so as to switch the target digital content to the target frame for display.

[0087] This embodiment illustrates the specific implementation of the incremental loading mechanism in the frame switching scenario provided in this application, wherein, since common resources refer to resources that can be reused in multiple frames, such as background images, common fonts or other basic components, these resources do not need to be reloaded each time the frame is switched, because they are common in different frames. Therefore, retaining these common resources can reduce repeated loading, save bandwidth and processing time. Before switching to a new target frame, remove the difference resources previously used to display the historical frame. These difference resources are specific to the historical frame and are no longer applicable to the new target frame. Removing these resources can free up memory space and ensure that the old frame content does not interfere with the display of the new frame. After removing the difference resources of the loaded historical frames, the difference resources related to the target frame can be read from the multi-frame material package according to the needs of the target frame and loaded into the system. These difference resources are specific to the target frame and may be new image layers, texts or other elements. They will be used to replace or supplement the public resources to form a complete new frame content. After completing the retention of public resources, the removal of historical difference resources and the loading of new difference resources, the target digital content can be smoothly switched to the target frame for display.

[0088] Through this implementation, the frame content can be updated efficiently, ensuring that each switch is a minimized data change, thereby improving performance and reducing unnecessary resource waste, and is particularly suitable for application scenarios that require frequent updates to display content.

[0089] Based on any of the above implementations, in some modified implementations, before responding to the frame switching instruction for the target digital content and determining the target frame to be displayed, the method further includes:

[0090] In response to the initial display instruction for the target digital content, determining an initial display frame of the target digital content;

[0091] Read all content resources related to the first display frame from the multi-frame material package corresponding to the target digital content;

[0092] All content resources related to the initial display frame are loaded to display the target digital content in the initial display frame.

[0093] Among them, the initial display instruction is triggered when the target digital content is displayed for the first time. After detecting the initial display instruction, it is first necessary to determine in which frame the target digital content should be displayed. Based on the display environment information at this time, such as device information, preference settings or other factors, it can be decided which frame to use as the initial display version, thereby determining the initial display frame. Since no content resources of the target digital content have been loaded at this time, it is necessary to read all content resources related to the initial display frame for loading, and combine them to form a complete initial display frame to display the target digital content. It is not just about loading difference resources, but loading all necessary resources to ensure that the user can see a complete and correct initial display screen.

[0094] This implementation ensures that when digital content is displayed for the first time, users can obtain a complete and correct initial experience. At the same time, it also lays the foundation for subsequent frame switching operations, because all resources loaded during the initial display include common resources, which helps to achieve incremental loading in future frame switching processes, thereby improving efficiency and reducing resource consumption. This method is very suitable for application scenarios that need to respond quickly to user requests and ensure the initial loading speed.

[0095] It should be noted that, in actual applications, an independent material package is currently generated for each frame. When the frame is switched, the current material package needs to be completely unloaded and a complete set of material packages needs to be reloaded. This practice not only has the problems of low frame switching efficiency and poor fluency, but also forces the client to re-download the complete material every time it switches, resulting in unnecessary network traffic consumption and storage space occupation. In addition, the client software needs to select the corresponding material package according to the current screen direction for full loading, which increases the resource consumption of the program and prolongs the response time. The material package generation method provided in any of the above embodiments of the present application significantly reduces the overall size of the material package by incorporating public resources for reuse in multiple frames into the material package and reusing these resources in different frames, avoiding the redundancy caused by the need to independently prepare a complete set of resources for each frame in the traditional method, optimizing the utilization of storage space, and the client only needs to download a multi-frame material package to support switching between different frames, without the need to frequently download different material packages, thereby reducing resource waste. The intelligent loading mechanism provided by the solution of the present application can only load new or changed resources when switching between different frames, rather than reloading the entire set of materials, thereby reducing the delay in the switching process, improving the smoothness when switching between different frames, and improving the user experience.

[0096] In a specific implementation, reference may be made to Figures 2 to 4 To understand, Figure 2 A schematic diagram of the structure of a material package provided in an embodiment of the present application. Figure 3A schematic diagram of a horizontal screen frame referencing content resources in a material package provided in an embodiment of the present application, Figure 4 A schematic diagram of a vertical screen frame referencing content resources in a material package provided in an embodiment of the present application, such as Figure 2 As shown, the material package is used to support the display of two frame sizes, 16v9 and 9v16. The difference resources include the horizontal screen pictures corresponding to 16v9 and the vertical screen pictures corresponding to 9v16. The public resources include mask videos and background music. It also includes two frame resource description files 16v9.json and 9v16.json, and schematically marks the reference relationship between the frame resource description file and the content resource. Among them, 16v9.json references the public resource and the difference resource "horizontal screen picture", and 9v16.json references the public resource and the difference resource "vertical screen picture".

[0097] Please refer to Figure 3 If the initial display frame is horizontal, the rendering engine reads the frame resource description file 16v9.json according to the initial display frame, and then loads the horizontal screen image and mask video according to the content resources referenced by 16v9.json.

[0098] Please continue to refer to Figure 4 When the user device switches from landscape to portrait, the rendering engine reads the frame resource description file 9v16.json according to the frame switching instruction, and compares it with 16v9.json to find the difference resources (landscape picture-vertical picture). Then, the landscape picture is unloaded and the vertical picture is loaded. During this process, there is no need to repeatedly load the public resource mask video, which saves this part of the overhead, thereby effectively improving the efficiency and smoothness of frame switching.
