[0043] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0044] In existing dual-screen TVs, the main screen on the top is used to play TV programs or streaming media content, and the sub-screen on the bottom is used to display customized content such as advertisements or weather. TV programs or streaming media content on the main screen are often accompanied by scrolling subtitles at the bottom. Although these subtitles are crucial to understanding the plot, they inevitably distract users' attention and affect users' viewing of video content.

[0045] In view of the above-mentioned defects of the prior art, the present invention provides a dual-screen TV subtitle display method, a dual-screen TV and a storage medium, which belongs to the field of TV display technology. The method includes: obtaining an initial video resource; detecting a subtitle suppression method of the initial video resource; processing the initial video resource according to the subtitle suppression method to obtain a target subtitle and a target video; in response to an instruction to turn on subtitles, playing the target video on the main screen of the dual-screen TV, and playing the target subtitle on the secondary screen of the dual-screen TV synchronously. The present invention processes the initial video resource, separates the video and subtitles, and plays them synchronously on the main screen and secondary screen of the dual-screen TV, respectively, effectively solving the problem that the scrolling subtitles on the main screen of the dual-screen TV affect the user's viewing of the video content.

[0046] See also Figure 1 The dual-screen television subtitle display method described in the embodiment of the present invention comprises the following steps:

[0047] Step S100: Acquire initial video resources.

[0048] Specifically, the initial video resources are obtained from various sources, such as local storage devices, streaming media service platforms, external devices, etc. The initial video resources are video resources to be played on the dual-screen TV, which can be movies, TV series, documentaries, live sports events, and other types.

[0049] See also Figure 1 The dual-screen television subtitle display method described in the embodiment of the present invention further includes the following steps:

[0050] Step S200: Detecting the subtitle compression method of the initial video resource.

[0051] Specifically, in the prior art, subtitles are usually compressed into videos in three forms. The first is an external subtitle form, that is, the subtitle file is transmitted together with the video file, and the player automatically loads it; the second is an internal subtitle form, in which the subtitle is encoded into the video container as a single video file and played together with the video code stream; the third is an embedded subtitle form, in which the subtitle and the video are combined into one video file, and the subtitle is played together as part of the image of the video frame. After the initial video resource is acquired, the present invention needs to detect its subtitle compression method, so as to subsequently separate the subtitles and video in the initial video resource according to the subtitle compression method.

[0052] In one implementation, the detecting the subtitle suppression method of the initial video resource includes:

[0053] Detecting whether the initial video resource includes a file;

[0054] If the initial video resource includes a video file and a subtitle file corresponding to the video file, determining that the subtitle compression method of the initial video resource is a subtitle plug-in method;

[0055] If the initial video resource only includes a video file, the video file of the initial video resource is analyzed to determine a subtitle compression method of the initial video resource.

[0056] Specifically, when the initial video resource is detected, the video file and the subtitle file are searched according to the preset matching rules. If the matching video file and subtitle file are found, it is considered that the video file corresponds to the subtitle file. The matching rule can be the same name, that is, when it is found that the name of the video file and the subtitle file are the same, it is considered that the video file corresponds to the subtitle file with the same name. At this time, it is determined that the subtitle compression method of the initial video resource is the subtitle plug-in method. If the initial video resource only contains video files, further analysis is performed to determine its subtitle compression method. The present invention can not only identify the subtitle plug-in method (that is, the video file and the subtitle file are stored separately), but also further analyze the subtitle compression method when only the video file is included. This increases the flexibility and scope of application of the method, and can cope with video resources with different subtitle compression methods. After accurately judging the subtitle compression method, different subsequent processing strategies can be adopted according to different methods.

[0057] In one implementation, analyzing the video file of the initial video resource to determine the subtitle compression method of the initial video resource includes:

[0058] Parsing the container format of the video file, and if independent subtitle track information is detected in the container format, determining that the subtitle compression mode of the initial video resource is an internal subtitle compression mode;

[0059] If no independent subtitle track information is detected, the image frame of the video file is analyzed, and if subtitle information exists in the image frame, it is determined that the subtitle compression mode of the initial video resource is a subtitle embedded mode.

[0060] Specifically, the container format of the video file is parsed first. The container format determines how the video and subtitles are packaged together. The container format can be MP4, MKV, AVI, etc. When parsing the container format, it will detect whether there is independent subtitle track information in the container format. If so, the subtitle compression method is determined to be subtitle internal. If not, the image frame of the video file is analyzed. If the subtitle information can be extracted from the image frame using image processing technology, the subtitle compression method is determined to be subtitle embedded, which means that the subtitle data has been directly embedded into the video frame and becomes part of the video.

[0061] See also Figure 1 The dual-screen television subtitle display method described in the embodiment of the present invention further includes the following steps:

[0062] Step S300: Process the initial video resource according to the subtitle compression method to obtain target subtitles and target video.

[0063] Specifically, according to different subtitle compression methods, the initial video resources are processed in different ways to separate the target subtitles and target videos in the initial video resources. The target subtitles are the subtitle files in the initial video resources, and the target video is the video file in the initial video resources. The separated subtitles and videos provide more choices and convenience. Users can choose whether to display subtitles according to their needs. At the same time, since the subsequent target video and target subtitles are played on the main screen and the secondary screen respectively, it also effectively solves the problem that the scrolling subtitles on the main screen of the dual-screen TV affect the user's viewing of video content.

[0064] In one implementation, the processing of the initial video resource according to the subtitle suppression method to obtain target subtitles and target video includes:

[0065] If the subtitle compression method is a subtitle plug-in method, the video file in the initial video resource is used as the target video, and the subtitle file corresponding to the video file is used as the target subtitle;

[0066] If the subtitle compression method is the subtitle internal sealing method, parsing the container format of the video file, extracting the subtitles therein as target subtitles, and using the video after removing the subtitles as the target video;

[0067] If the subtitle suppression method is a subtitle embedding method, a preset deep learning neural network is used to identify the subtitles in the video file as target subtitles, remove the subtitles in the video file, and perform image repair and filling processing on the subtitle removal area in the video file to obtain the target video.

[0068] Specifically, when the subtitle suppression method is the subtitle embedding method, the present invention will perform image repair and filling processing on the subtitle removal area in the video through a deep learning neural network, which can provide a better quality video picture and effectively improve the user's visual experience. In a dual-screen TV environment, the scrolling subtitles on the main screen tend to distract the user's attention and affect the user's focus on watching the video content. By displaying the target subtitles on the secondary screen and only displaying the pure video picture on the main screen, the user can focus more on the video content and improve the viewing experience.

[0069] In one implementation, the method of using a preset deep learning neural network to identify subtitles in the video file as target subtitles, removing subtitles from the video file, and performing image restoration and padding processing on the subtitle removal area in the video file to obtain a target video includes:

[0070] Processing the video file using a preset deep learning neural network to identify image elements and subtitles of each frame in the video file;

[0071] Using the identified subtitles as target subtitles;

[0072] According to the identified image elements, the subtitle removal area in the video file is repaired and filled to obtain the target video.

[0073] Specifically, the video file is processed using a deep learning neural network, and each frame of the video file is input into the deep learning neural network, which recognizes the image elements and subtitles of each frame.

[0074] In one implementation, the deep learning neural network includes an input layer, a convolution layer, a pooling layer, a fully connected layer, and an output layer; the processing of the video file using a preset deep learning neural network to identify image elements and subtitles of each frame in the video file includes:

[0075] Input the video file into the input layer of the deep learning network, and transmit it to the convolution layer through the input layer;

[0076] Extracting features from the video file through the convolution layer to obtain an initial feature map, which is then transmitted to the pooling layer;

[0077] The pooling layer uses a preset strategy to perform dimensionality reduction processing on the initial feature map to obtain a second feature map, which is transmitted to the fully connected layer;

[0078] The features extracted from the second feature map are integrated and mapped through the fully connected layer to obtain a number of feature vectors, which are transmitted to the output layer and processed by the output layer to output the image elements and subtitles of each frame in the video file.

[0079] Specifically, in the present invention, the deep learning neural network is a convolutional neural network model (CNN). Figure 2 As shown, after each frame of the video file is input, it is processed by the convolution layer, pooling layer, and fully connected layer to identify the image elements and subtitles of each frame. The present invention uses a deep learning neural network to extract the image elements and subtitles of each frame. After the target subtitles are extracted, the subtitle removal area in the video file can be repaired and filled according to the identified image elements to obtain the target video, so that the user can obtain complete and high-quality picture content, which provides a basis for the subsequent use of the main screen and the secondary screen of the dual-screen TV to display the video and subtitles.

[0080] In one implementation, a SOC (System on chip) is used to obtain an image of each frame in an input video file, and multiple frames are stored in a cache, so as to reserve enough time for subsequent algorithms to process images and subtitles.

[0081] See also Figure 1 The dual-screen television subtitle display method described in the embodiment of the present invention further includes the following steps:

[0082] Step S400, in response to the subtitle opening instruction, the target video is played on the main screen of the dual-screen TV, and the target subtitles are synchronously played on the secondary screen of the dual-screen TV.

[0083] Specifically, the present invention has three commands for subtitles, namely, closing subtitles, opening subtitles and hiding subtitles, which can be sent based on a remote control or voice command, and are not limited here. When the TV receives the command, the command is displayed on the secondary screen, such as Figure 3 When the subtitle opening command is issued, the SOC (System on chip) will play the target video and target subtitles on the main screen and the secondary screen of the dual-screen TV respectively, as shown in FIG. Figure 4 This method can effectively improve the user's viewing experience of video content.

[0084] In one implementation, playing the target video on the main screen of the dual-screen TV and synchronously playing the target subtitles on the secondary screen of the dual-screen TV include:

[0085] Performing time synchronization processing on the target video and the target subtitles using a preset synchronization algorithm;

[0086] The target video after synchronization processing is played on the main screen of the dual-screen TV, and the target subtitles are synchronously played on the secondary screen of the dual-screen TV.

[0087] Specifically, the present invention uses a preset synchronization algorithm to perform time synchronization processing on the target video and the target subtitles to ensure that the subtitles and video can be played synchronously. The preset synchronization algorithm can be a synchronization algorithm based on a timestamp.

[0088] In one implementation, after responding to the subtitle opening instruction, playing the target video on the main screen of the dual-screen TV, and synchronously playing the target subtitles on the secondary screen of the dual-screen TV, the method further includes:

[0089] In response to the hidden subtitle instruction, the target video is maintained to be played on the main screen of the dual-screen TV, and the target subtitle is stopped to be played on the secondary screen of the dual-screen TV.

[0090] Specifically, when the remote control issues a closed caption command, the SOC (System on chip) stops playing the target subtitles on the secondary screen of the dual-screen TV. At this time, only the main screen will play the video content, such as Figure 5As shown. Viewers can turn subtitles on or off at any time according to their needs, effectively improving the user's viewing experience. The closed subtitle function is very practical in many scenarios. For example, when watching foreign language movies or TV series, viewers can turn on subtitles to help understand the dialogue; when they are immersed in the plot and want to focus more on the picture and sound effects, or when they are practicing their listening skills, they can turn off subtitles at any time to avoid subtitles interfering with their vision.

[0091] In one implementation, the method further includes:

[0092] In response to the subtitle closing instruction, the initial video resource is played on the main screen of the dual-screen TV.

[0093] Specifically, when the dual-screen TV receives a command to turn off subtitles, the SOC (System on chip) directly plays the initial video resource on the main screen of the dual-screen TV, and no longer extracts subtitles to play on the secondary screen.

[0094] The process diagram for the three instructions in the present invention is as follows: Figure 6 As shown. When the remote control or voice issues a command to turn on subtitles, the "Subtitle" OSD menu switch button on the secondary screen is selected to the "On" option, the target subtitles and target video are processed by an algorithm, the image in the filled target video is displayed on the main screen of the dual-screen TV, and the target subtitles are displayed on the secondary screen. The "Subtitle" OSD menu is hidden after 5 seconds. This display method allows users to watch the video content on the main screen more attentively, effectively avoiding the impact of rolling subtitles on user viewing; when the remote control or voice issues a command to hide subtitles, the target subtitles and target video are processed by an algorithm, the image in the filled target video is displayed on the main screen of the dual-screen TV, and the target subtitles are hidden, and the "Subtitle" OSD menu is hidden after 5 seconds. This method allows users to turn off subtitles according to personal needs. In the case of immersive viewing of the plot or listening training, this method can be widely used; when the remote control or voice issues a command to turn off subtitles, no processing is done, and the initial video resources are directly displayed on the main screen. The "Subtitle" OSD menu is hidden after 5 seconds. In the present invention, the OSD menu is automatically hidden after 5 seconds to avoid interfering with the user's viewing, while retaining the flexibility of adjusting the subtitle settings at any time.

[0095] In one implementation, the size of the dual-screen TV main screen is larger than the size of the dual-screen TV sub-screen, and the dual-screen TV sub-screen is located below the dual-screen TV main screen.

[0096] Specifically, the schematic diagram of the dual-screen TV screen of the present invention is as follows Figure 7 The size of the main screen is larger than that of the sub-screen, and the sub-screen is located below the main screen.

[0097] In summary, the present invention obtains an initial video resource; detects a subtitle suppression method of the initial video resource; processes the initial video resource according to the subtitle suppression method to obtain a target subtitle and a target video; and responds to a subtitle opening instruction to play the target video on the main screen of a dual-screen TV, and synchronously plays the target subtitle on the secondary screen of the dual-screen TV. The present invention processes the initial video resource, separates the video and the subtitle, and synchronously plays them on the main screen and the secondary screen of the dual-screen TV, respectively, effectively solving the problem that the scrolling subtitles on the main screen of the dual-screen TV affect the user's viewing of the video content.
