Exemplarily, the display device 100 may be a TV, and the main processor 110 may be a built-in SoC (System-on-Chip, system-on-chip, also known as a system-on-chip) of the TV, which is integrated with one or more of the above-mentioned processing units, and the display processing The device 120 may be a TCON (Timing Controller, timing controller, also known as a logic board) of the TV.

The memory 130 may include a memory independent of the main processor 110 or the display processor 120, such as a flash memory, or may include a memory integrated in the main processor 110 or the display processor 120, such as a register.

The main processor 110 and the display processor 120 may be connected through a video transmission interface.

In an implementation manner, the display device 100 may further include a communication module, configured to implement network communication. For example, the communication module can provide wireless communication solutions such as wireless local area network, bluetooth, and near field communication applied on the display device 100, so that the display device 100 can obtain video data on the Internet.

The data processing method of the display device in this exemplary embodiment will be described below from two aspects of the main processor 110 and the display processor 120 respectively.

FIG. 2 shows an exemplary flow of the data processing method applied to the display device of the main processor 110, which may include the following steps S210 to S230:

Step S210, acquiring repeated frame data in the first video data, where the first video data includes continuous multi-frame data to be transmitted;

Step S220, filtering out repeated frame data from the first video data and adding indication information for the repeated frame data to obtain second video data;

Step S230, sending the second video data to the display processor of the display device, so that the display processor determines the repeated frame data according to the instruction information, and controls the display device to display the video corresponding to the first video data based on the second video data and the repeated frame data screen.

Based on the above method, when the main processor of the display device sends the first video data to the display processor, the duplicate frame data is filtered out from the first video data and instruction information for the duplicate frame data is added, and then the processed second video data is sent. data. On the one hand, the existence of repeated frame data indicates that the picture interval is static. At this time, for the situation of static pictures in the video picture, the repeated frame data is filtered out, which reduces the amount of video data actually sent, and further simplifies the processing of video data by the display processor. processing, thereby reducing the radiation generated by the display device during the data transmission process and data processing process, which is conducive to reducing the negative impact on the user's health. On the other hand, this solution does not need to modify the display device at the hardware level, and the processing of the first video data does not affect the normal display of the video image, so it has high practicability.

Each step in Fig. 2 is described in detail below.

Referring to FIG. 2 , in step S210 , repeated frame data in the first video data is acquired, and the first video data includes continuous multi-frame data to be displayed.

The first video data may be video data to be transmitted between the main processor 110 and the display processor 120 . The first video data includes continuous multiple frames of data to be displayed, and each frame of data is used to present a frame of picture. When the main processor 110 sends video data to the display processor 120, it usually does not send frame by frame, but sends continuous multi-frame data in one cycle, and the data to be transmitted in one cycle can be used as the first video data .

This disclosure does not limit the source of the first video data. For example, the first video data can be obtained from the cloud (such as an Internet video platform), or the first video data can be obtained by loading a local video file, or generated by running an application program. first video data. The first video data may be original video data to be displayed, including relatively complete picture information.

The repeated frame data refers to the same data in the continuous multiple frames of the first video data, that is, the presence of repeated frame data in the first video data indicates that there is a static picture in the video picture. For example, if it is detected that there are consecutive N frames of the same data in the first video data, the first frame data in the same data of the continuous N frames of pictures can be used as the repeated frame data, and the latter N-1 frame data can be used as the repeated frame data, Where N is a positive integer not less than 2.

In an implementation manner, the above-mentioned value of N may be determined according to the limitation of the number of frames stored by the display processor 120, related settings of video data transmission, and the like. Thus, when it is detected that there are consecutive N frames of data with the same picture in the first video data, the data of the last N−1 frames are taken as repeated frame data. That is to say, if there are multiple consecutive frames of the same data in the first video data, and the number of frames is less than N, it can be considered that there is no repeated frame data, and the processing of filtering out repeated frame data is not performed.

Continuing to refer to FIG. 2 , in step S220 , filter out repeated frame data from the first video data and add indication information for the repeated frame data to obtain second video data.

Since the repeated frame data belongs to repeated information, it can be filtered out from the first video data, and at the same time, indication information for the repeated frame data is added. The indication information may include the number of repeated frames, the position (such as a time stamp), the information of the repeated frame data, etc., so that the display processor 120 can restore the repeated frame data according to the indication information.

By performing the above processing on the first video data, the second video data is obtained. Compared with the first video data, the second video data reduces the repeated frame data and increases the indication information, and the data volume of the indication information is less than the data volume of the repeated frame data itself, so the second video data is actually a reference to the first video data. Data simplification enables multiplexing of repeated frame data.

In one embodiment, the first video data may include k sets of sub-video data, the k sets of sub-video data correspond to k display areas of the display device one-to-one, and k is a positive integer not less than 2. As shown in FIG. 3 , the screen of the display device 100 can be divided into k display areas, and each display area can be regarded as independent. When the main processor 110 sends video data to the display processor 120, it can be divided into k groups Sub-video data, each set of sub-video data is used for display in the corresponding display area. The value of k may be determined according to display performance or screen size, for example, for a display device with a resolution of 4K and a frame rate of 60 Hz, k may be 8.

Correspondingly, the above-mentioned filtering of repeated frame data from the first video data and adding indication information for the repeated frame data to obtain the second video data may include the following steps:

The repeated frame data is filtered out for the sub-video data in which the repeated frame data exists, and indication information for the repeated frame data is added to obtain the second video data.

Among them, when detecting repeated frame data, each group of sub-video data can be detected separately, so that it can be detected that part of the sub-video data has repeated frame data, and the other part of sub-video data does not have repeated frame data, that is, video If there is a partial static picture in the picture, the repeated frame data is further filtered out for the sub-video data in which there is repeated frame data, and indication information for the repeated frame data is added. The processed sub-video data and sub-video data without repeated frame data (these sub-video data do not need to be processed to filter out repeated frame data and add indication information) form second video data. In this way, the video data can be simplified for the case where there is a partial static picture in the video picture.

In one embodiment, when filtering out repeated frame data from the first video data, the data processing method of the display device may further include the following steps:

A replacement value is filled in the position of the filtered repeated frame data in the second video data.

Wherein, the replacement value may be a preset value, such as 0 or 1, etc., for example, the positions of all repeated frame data may be filled with 0; or the replacement value may be an identifier, sequence number, etc. of the repeated frame. In this way, the second video data and the stability of the connection between the main processor 110 and the display processor 120 can be improved, so as to solve the problem of frequent disconnection of the connection and time-consuming re-establishment of the connection.

In an implementation manner, as shown in FIG. 4 , the above indication information may include a repeated frame indication bit in the second video data. Correspondingly, the above-mentioned filtering out repeated frame data from the first video data and adding information for the repeated frame data may include the following steps S410 and S420:

Step S410, filtering out repeated frame data from the first video data;

Step S420, according to the information of the filtered repeated frame data, assign a value to the repeated frame indicator bit.

Wherein, the repeated frame indication bit is used to indicate the information of the repeated frame data, such as the number of repeated frames, the position (such as a time stamp), the information of the repeated frame data, and the like. For example, the repeated frame indicator bit may be assigned a value according to the frame number corresponding to the repeated frame data. Exemplarily, the first video data and the second video data may use V*1 format signals, and 1 byte is reserved in the second video data as a repeated frame indicator bit. When the value of the repeated frame indicator bit is FF, it means There is no repeated frame, and when the value of the repeated frame indicator bit is not FF, it indicates the frame number corresponding to the repeated frame data. Thus, the display processor 120 can determine the information of the repeated frame data according to the repeated frame indicator bit in the second video data, and then restore the repeated frame data.

In one embodiment, each frame of data in the second video data includes a repeating frame indication bit, and the repeating frame indicating bit is used to indicate the number of repeated frames of each frame of data. For example, in the second video data, the starting position of each frame of data is the repeated frame indicator bit of this frame, which is used to indicate the number of frames that this frame is repeated. When the repeated frame indicator bit is FF, it means that this frame has no Repeat, if the repeated frame indicator bit is not FF, it means that the next several frames starting from this frame (corresponding to the value of the repeated frame indicator bit) are repeated frames.

Continuing to refer to FIG. 2, in step S230, the second video data is sent to the display processor of the display device, so that the display processor determines the repeated frame data according to the instruction information, and controls the display device to display the frame data based on the second video data and the repeated frame data. A video frame corresponding to the first video data.

Generally, the main processor 110 can send the second video data to the display processor 120 through the video data interface. The display processor 120 analyzes the second video data, especially, can restore the filtered repeated frame data according to the indication information in the second video data, and the second video data and the repeated frame data are equivalent to the first video data. The display processor 120 may control the display device 100 to display the video picture corresponding to the first video data based on the second video data and the repeated frame data, including the static picture corresponding to the filtered repeated frame data.

In one embodiment, the above-mentioned sending of the second video data to the display processor of the display device may include the following steps:

Send k groups of sub-video data to the display processor through k signal transmission channels, wherein the k signal transmission channels correspond to k display areas one by one, and each signal transmission channel is used to transmit a group of second video data sub video data.

Wherein, k sets of sub-video data refer to k sets of sub-video data in the second video. Referring to FIG. 5 , k signal transmission channels (Lanes) may be set between the main processor 110 and the display processor 120 , and FIG. 5 exemplarily shows that k is 8. Referring to FIG. Lane0 is used to transmit the first group of sub-video data in the second video data, Lane1 is used to transmit the second group of sub-video data in the second video data, and so on. If a group of sub-video data is filtered out of repeated frame data, the group of sub-video data is significantly simplified, which can reduce the amount of data transmitted by the corresponding transmission channel, thereby reducing radiation.

FIG. 6 shows an exemplary flow of the data processing method applied to the display device of the display processor 120, which may include the following steps S610 to S630:

Step S610, receiving the second video data sent by the main processor of the display device, the second video data is obtained by the main processor after filtering out repeated frame data from the first video data and adding instruction information for the repeated frame data;

Step S620, determining repeated frame data according to the above indication information;

Step S630, based on the second video data and the repeated frame data, control the display device to display the video picture corresponding to the first video data.

Wherein, the display processor 120 may determine information such as repeated frame data, frame number, and position corresponding to the filtered repeated frame data according to the indication information in the second video data.

In one embodiment, the indication information in the second video data may include a repeated frame indication bit, and the display processor 120 may determine the information of the repeated frame data according to the value of the repeated frame indication bit by analyzing the repeated frame indication bit.

In one embodiment, each frame in the second video data includes a repeated frame indicator bit, and the display processor 120 can analyze the repeated frame indicator bit frame by frame to determine whether each frame of data is repeated and the repeated frame number.

The display processor 120 may combine the second video data and the indication information to parse out the filtered repeated frame data. Exemplarily, the display processor 120 determines the position of the repeated frame data, the number of frames, the corresponding repeated frame data, etc. according to the indication information, and reads the repeated frame data from the second video data, thereby restoring the repeated frame data.

In one embodiment, the second video data includes replacement values filled at the positions of the filtered repeated frame data. The display processor 120 may ignore the replacement value in the second video data according to the indication information, so as to reduce the amount of data processing. For example, the display processor 120 analyzes the repeated frame indicator bit of the i-th frame in the second video data, and determines that the next p frames are repeated frames, then the next p frames of data can be ignored, and repeatedly call The data of the i-th frame is used as the repeated frame data of the p-frame.

After the display processor 120 parses out the repeated frame data, it can control the display device to display the video picture corresponding to the first video data. The second video data and the repeated frame data are equivalent to the first video data, so that the image to be displayed can be completely restored. video footage.

Based on the above method, the processing of the video data by the display processor is simplified, thereby reducing the radiation generated by the display device during data processing, which is beneficial to reducing the negative impact on the user's health.

Fig. 7 shows an exemplary interaction flow of a data processing method of a display device, including:

Step S710, the main processor 110 detects whether there are consecutive N frames of the same picture data in the first video data, if not, execute step S720, if yes, execute step S730;

Step S720, the main processor 110 sends the first video data to the display processor 120 as the second video data;

Step S730, the main processor 110 replaces the last N-1 frame data with a preset value, and sets the repeated frame indicator bit to obtain the second video data, and sends it to the display processor 120;

Step S740, the display processor 120 receives the second video data;

In step S750, the display processor 120 analyzes the second video data to identify whether there is repeated frame data, if not, execute step S760, and if yes, execute step S770;

Step S760, normally process the second video data for display;

In step S770, the data of the repeated frame is written into the content, and called repeatedly in the next N-1 frames for display.

Compared with the first video data, the data amount of the second video data is reduced, thereby reducing radiation generated by the display device 100 during data transmission and processing, and also reducing power consumption of the display device 100 .
