Referring to fig. 1, the display device 100 may include a main processor 110, a display processor 120, and a memory 130. The main processor 110 is used to perform the main logic processing of the display device 100, such as running an operating system and application programs of the display device 100. The display processor 120 is configured to perform display signal processing of the display device 100, and for example, may convert video data generated by the main processor 110 into signals capable of driving a display screen. The memory 130 is used to store executable instructions that may be executed by the main processor 110 or the display processor 120 to implement corresponding functions.
The main processor 110 may include one or more processing units, such as: the host processor 110 may include an AP (Application Processor ), a modem processor, a GPU (Graphics Processing Unit, graphics processor), an ISP (Image Signal Processor ), a controller, an encoder, a decoder, a DSP (Digital Signal Processor ), a baseband processor, and/or an NPU (Neural-Network Processing Unit, neural network processor), etc.
An encoder may encode (i.e., compress) an image or video to reduce the data size for storage or transmission. The decoder may decode (i.e., decompress) the encoded data of the image or video to recover the image or video data. The display device 100 may support images or video in a variety of encoding formats, such as: image formats such as JPEG (Joint Photographic Experts Group ), PNG (Portable Network Graphics, portable network graphics), BMP (Bitmap), and video formats such as MPEG (Moving Picture Experts Group ) 1, MPEG2, h.263, h.264, HEVC (High Efficiency Video Coding ).
The display processor 120 may include a core circuit for controlling the timing of the display device 100, for controlling when the scan driving circuit of the display device 100 is activated, and signal format conversion of video data, thereby controlling the display device 100 to display video pictures.
For example, the display device 100 may be a television, the main processor 110 may be a SoC (System-on-Chip, also referred to as a System-on-Chip) built in the television, the one or more processing units are integrated, and the display processor 120 may be a TCON (Timing Controller, timing controller, also referred to as a logic board) of the television. Alternatively, the display device 100 may be a PC (Personal Computer ), the main processor 110 may be a CPU (Central Processing Unit ) or a GPU provided on a main board of the PC, and the display processor 120 may be an MCU (Micro-Controller Unit) built in a display of the PC.
A connection may be formed between the main processor 110 and the display processor 120 through a video transmission interface.
In one embodiment, the display device 100 may further include a communication module for implementing network communication. For example, the communication module may provide a wireless communication solution for wireless local area network, bluetooth, near field communication, etc. applied on the display device 100, whereby the display device 100 may obtain video data on the internet.
The data processing method of the display device in the present exemplary embodiment will be described below from both the main processor 110 and the display processor 120, respectively.
Fig. 2 shows an exemplary flow of a data processing method applied to the display device of the main processor 110, and may include the following steps S210 to S230:
step S210, acquiring repeated frame data in first video data, wherein the first video data comprises continuous multi-frame data to be transmitted;
step S220, filtering repeated frame data from the first video data and adding indication information aiming at the repeated frame data to obtain second video data;
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 indication information, and controls the display device to display the video frame corresponding to the first video data based on the second video data and the repeated frame data.
Based on the method, when the main processor of the display device sends the first video data to the display processor, the repeated frame data are filtered out from the first video data, the indication information for the repeated frame data is added, and then the processed second video data are sent. On the one hand, the existence of the repeated frame number indicates that the picture interval is static, and at the moment, the repeated frame data is filtered out according to the condition that the static picture exists in the video picture, so that the amount of video data actually transmitted is reduced, the processing of the video data by a display processor is further simplified, the radiation generated by display equipment in the data transmission process and the data processing process is reduced, and the negative influence on the physical health of a user is reduced. On the other hand, the scheme does not need to modify the display equipment from the hardware level, and the processing of the first video data does not influence the normal display of the video picture, so that the method has higher practicability.
Each step in fig. 2 is specifically described below.
Referring to fig. 2, in step S210, repeated frame data in first video data including consecutive multi-frame data to be displayed is acquired.
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 comprises continuous multi-frame data to be displayed, and each frame of data is used for presenting one frame of picture. When transmitting video data to the display processor 120, the main processor 110 generally transmits continuous multi-frame data not frame by frame but within one period, and may use data to be transmitted within one period as first video data.
The source of the first video data is not limited in the present disclosure, for example, the first video data may be obtained from a cloud (such as an internet video platform), the first video data may be obtained by loading a local video file, and the first video data may be generated by running an application program. The first video data may be original video data to be displayed, including relatively complete picture information.
The repeated frame data refers to the data with the same continuous multi-frame picture in the first video data, namely, the repeated frame data exists in the first video data, which indicates that a static picture exists in the video picture. For example, when it is detected that there is data identical to consecutive N frames in the first video data, the first frame data in the data identical to consecutive N frames may be regarded as repeated frame data, and the latter N-1 frame data may be regarded as repeated frame data, where N is a positive integer not less than 2.
In one embodiment, the value of N may be determined based on a limit on the number of frames stored by display processor 120, a related setting for video data transmission, and the like. Thus, when it is detected that there is the same data of consecutive N frames in the first video data, the latter N-1 frames thereof are regarded as the repeated frame data. That is, if the first video data has the same frame number of consecutive multi-frame pictures, which is less than N, it can be regarded that there is no repeated frame data, and the process of filtering out the repeated frame data is not performed.
With continued reference to fig. 2, in step S220, repeated frame data is filtered out from the first video data and indication information for the repeated frame data is added, resulting in second video data.
Since the repeated frame data belongs to the repeated information, it is possible to filter out from the first video data while adding the indication information for the repeated frame data. The indication information may include the number, location (e.g., time stamp) of the repeated frames, information of the repeated frame data, etc., so that the display processor 120 restores the repeated frame data according to the indication information.
And obtaining second video data by performing the processing on the first video data. The second video data is reduced in the repeated frame data and the indication information is increased in comparison with the first video data, and the data amount of the indication information is smaller than the data amount of the repeated frame data itself, so that the second video data is actually simplification of the first video data, and the repeated frame data can be multiplexed.
In one embodiment, the first video data may include k sets of sub video data, where k sets of sub video data are in one-to-one correspondence with k display areas of the display device, and k is a positive integer not less than 2. Referring to fig. 3, the screen of the display device 100 may be divided into k display areas, each of which may be regarded as separate, and the main processor 110 may be divided into k sets of sub-video data each for display in the corresponding display area when transmitting video data to the display processor 120. The value of K may be determined according to display performance or screen size, for example, K may be 8 for a 4K resolution, 60Hz frame rate display device.
Correspondingly, filtering the repeated frame data from the first video data and adding the indication information for the repeated frame data to obtain the second video data may include the following steps:
filtering the repeated frame data from the sub video data with the repeated frame data, and adding indication information aiming at the repeated frame data to obtain second video data.
When detecting the repeated frame data, the repeated frame data can be detected for each group of sub-video data, so that the situation that one part of the sub-video data has the repeated frame data and the other part of the sub-video data does not have the repeated frame data, namely, the situation that a local static picture exists in a video picture can be detected, and then the repeated frame data are filtered out for the sub-video data with the repeated frame data and the indication information for the repeated frame data is added. The processed sub-video data and the sub-video data without the repeated frame data (these sub-video data do not need to be processed to filter out the repeated frame data and add the indication information) form the second video data. Thus, the video data can be simplified for the case where a local still picture exists in the video picture.
In one embodiment, the data processing method of the display device may further include the steps of:
and filling replacement values in the positions of the filtered repeated frame data in the second video data.
The replacement value may be a preset value, such as 0 or 1, for example, the positions of all the repeated frame data may be filled with 0; or the replacement value may be an identification of the repeated frame, a sequence number, etc. Thus, the stability of the connection between the main processor 110 and the display processor 120 and the second video data can be improved to improve the problem that the connection is frequently disconnected and the time is consumed for reestablishing the connection.
In one embodiment, referring to fig. 4, the indication information may include a repeated frame indication bit in the second video data. Accordingly, filtering the repeated frame data from the first video data and adding the information for the repeated frame data may include the following steps S410 and S420:
step S410, filtering repeated frame data from the first video data;
and step S420, assigning repeated frame indication bits according to the filtered repeated frame data information.
Wherein the repeated frame indication bit is used to indicate information of repeated frame data, such as the number of repeated frames, the position (e.g., time stamp), information of repeated frame data, etc. For example, the repeated frame indication bit may be assigned according to the number of frames corresponding to the repeated frame data. For example, the first video data and the second video data may adopt signals in v×1 format, and 1byte bit is reserved in the second video data as a repeated frame indicator bit, where when the value of the repeated frame indicator bit is FF, it indicates that there is no repeated frame, and when the value of the repeated frame indicator bit is not FF, it indicates the number of frames corresponding to the repeated frame data. Thus, the display processor 120 may determine the information of the repeated frame data according to the repeated frame indication bit in the second video data, and restore the repeated frame data.
In one embodiment, each frame of the second video data includes a repeated frame indication bit for indicating the number of frames each frame of data is repeated. For example, in the second video data, the start position of each frame data is a repeated frame indicating bit of the present frame, which indicates the number of frames in which the present frame is repeated, for example, when the repeated frame indicating bit is FF, it indicates that the present frame is not repeated, for example, when the repeated frame indicating bit is not FF, it indicates that a number of frames (corresponding to the value of the repeated frame indicating bit) next from the present frame are repeated.
With continued reference 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 indication information, and controls the display device to display the video picture corresponding to the first video data based on the second video data and the repeated frame data.
In general, the main processor 110 may transmit the second video data to the display processor 120 through the video data interface. The display processor 120 parses the second video data, and in particular, may restore the filtered repeated frame data according to the indication information in the second video data, where the second video data and the repeated frame data correspond to the first video data. The display processor 120 may control the display device 100 to display a video picture corresponding to the first video data based on the second video data and the repeated frame data, including a still picture corresponding to the filtered repeated frame data.
In one embodiment, the foregoing display processor for transmitting the second video data to the display device may include the steps of:
and respectively transmitting the k groups of sub-video data to the display processor through k signal transmission channels, wherein the k signal transmission channels are in one-to-one correspondence with the k display areas, and each signal transmission channel is used for transmitting one group of sub-video data in the second 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 (Lane) may be provided between the main processor 110 and the display processor 120, and fig. 5 exemplarily shows that k is 8. Lane0 is used to transmit a first set of sub-video data in the second video data, lane1 is used to transmit a second set of sub-video data in the second video data, and so on. If a certain group of sub-video data is filtered out by repeated frame data, the group of sub-video data is obviously simplified, and the data quantity transmitted by a corresponding transmission channel can be reduced, so that radiation is reduced.
Fig. 6 shows an exemplary flow of a data processing method applied to a display device of the display processor 120, which may include the following steps S610 to S630:
step S610, receiving second video data sent by a main processor of the display device, wherein the second video data is obtained after the main processor filters repeated frame data from the first video data and adds indication information for the repeated frame data;
step S620, determining repeated frame data according to the indication information;
in step S630, the display device is controlled to display a video picture corresponding to the first video data based on the second video data and the repeated frame data.
The display processor 120 may determine, according to the indication information in the second video data, information such as the repeated frame data, the frame number, and the position corresponding to the filtered repeated frame 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 by parsing the repeated frame indication bit according to the value of the repeated frame indication bit.
In one embodiment, each frame in the second video data includes a repeat frame indication bit, and the display processor 120 may parse the repeat frame indication bit from frame to determine whether each frame of data is repeated and the number of frames that are repeated.
The display processor 120 may analyze the filtered repeated frame data in combination with the second video data and the indication information. Illustratively, the display processor 120 determines the position, the number of frames, the corresponding repeated frame data, etc. of the repeated frame data according to the indication information, reads the repeated frame data from the second video data, and restores the repeated frame data.
In one embodiment, the second video data includes replacement values that are padded at the locations of the filtered out repeated frame data. The display processor 120 may ignore the replacement value in the second video data according to the indication information to reduce the data processing amount. For example, the display processor 120 parses the repeated frame indication bit of the i-th frame in the second video data, determines that the next p-frame is a repeated frame, and may ignore the next p-frame data and repeatedly call the data of the i-th frame as the p-frame repeated frame data.
After parsing the repeated frame data, the display processor 120 may control the display device to display a video frame corresponding to the first video data, where the second video data and the repeated frame data correspond to the first video data, so that the video frame to be displayed can be completely restored.
Based on the method, the processing of the video data by the display processor is simplified, so that the radiation generated by the display device in the data processing process is reduced, and the negative influence on the physical health of a user is reduced.
Fig. 7 shows an exemplary interaction flow of a data processing method of a display device, comprising:
