As in the ultra high definition video industry, the amount of data that the TCON board needs to process is large. The basic processing flow of the TCON board is a full-time processing system, the front-end SOC mainboard sends images to a data receiving module RX of the TCON board, the images are analyzed by the data receiving module and then sequentially transmitted to each image processing module, and finally the images are sent to a signal output module TX, so that each module of the TCON board is kept on all the time, the function is closed unless the power is initially powered on, and the power consumption of the whole equipment is kept at a higher value. In order to reduce the power consumption of the device, in the embodiment of the present application, the SOC motherboard 210 may include a data processing module and a data transmitting module.
The data processing module is used for determining characteristic information corresponding to the image information according to the change relationship between the image information of each pixel point in the current image frame and the image information of the pixel point at the same position in the adjacent image frame, and generating image data containing the image information and the characteristic information. The characteristic information is used for indicating whether an image frame corresponding to the image data is a static image frame or not, and each pixel point in the static image frame is the same as the image information of the pixel point located at the same position in the adjacent image frame.
And a data sending module, configured to send the image data to the TCON board 220, so that the TCON board 220 determines whether it is necessary to control the image processing module to continue processing the image information in the received image data according to the feature information in the image data.

Because the TCON board of the embodiment of the present application controls the image processing module to suspend processing of the image information in the received image data when determining that the current image frame corresponding to the image data is the still image frame according to the feature information in the received image data, compared with the prior art in which the video processing device needs to process the image information of each received image frame, the TCON board can effectively reduce the power consumption of the device and prolong the service life of a chip in the device.

The characteristic information is used for indicating whether an image frame corresponding to the image data is a static image frame or not, and each pixel point in the static image frame is the same as the image information of the pixel point at the same position in the adjacent image frame. The change relationship refers to whether the image information of each pixel point in the current image frame is consistent with the image information of the pixel point at the same position in the adjacent image frame, and if the pixel value of a certain pixel point in the current image frame is inconsistent with the pixel value of the pixel point at the same position in the adjacent image frame, the pixel point is changed in the front and back image frames.

Specifically, the feature information in the image data may include pixel STATIC information STATIC and image STATIC information STATIC, where the pixel STATIC information STATIC is used to indicate whether a current pixel is a STATIC pixel, and image information of the STATIC pixel in a current image frame is the same as image information of a pixel located at the same position in an adjacent image frame; for example, when the STATIC information STATIC of the pixel point is equal to 1, it indicates that the current pixel point is a STATIC pixel point, and when the STATIC information STATIC of the pixel point is equal to 0, the current pixel point is not a STATIC pixel point. The image static information STATICGL is used for marking whether the current image frame corresponding to the image data is a static image frame; when the image still information statcgl is equal to 1, it indicates that the current image frame corresponding to the image data is a still image frame, and when the image still information statcgl is equal to 0, it indicates that the current image frame corresponding to the image data is not a still image frame.
The power consumption adjusting module 224 is further configured to, when the pixel still information indicates that the current pixel is a still pixel, and the image still information indicates that the current image frame is a still image frame, suspend updating the image information stored in the image caching module 224; if the pixel still information indicates that the current pixel is a static pixel and the image still information indicates that the current image frame is not a static image frame, discarding the image information of the current pixel and updating the image information of the current image frame that is not a static pixel to the image cache module 224.
That is, if both the feature information STATIC and STATIC are equal to 1, it is determined that the later incoming image data is no longer changed, and the data update to the image cache module (DDR2) is stopped. If the characteristic information STATIC is equal to 1 but the STATIC is equal to 0, the image information of the current pixel point is discarded, and the image information that is not a STATIC pixel point in the current image frame is updated to the image cache module 224.
The feature information in the image data may further include image long-term still information, able, for indicating whether image frames in a preset time period after the current image frame are all static image frames, where the preset time period is a longer time period. When the image long-term still information IMBLE is equal to 1, it indicates that the received image data is still and will remain for a long time. If the received image data is still and remains for a long time, the video decoding apparatus at the front end may stop transmitting the data. At this time, the signal monitoring frequency of the data receiving module 221 and the refresh frequency of the signal output module 225 may be reduced to further reduce the device power consumption.
Alternatively, the video processing apparatus may further include a moving Picture processing module, for example, a MEMC (Motion estimation and Motion Compensation) module or an OD (Over Drive) module, which may be collectively referred to as a PQ (Picture Quality control) module. The moving picture processing module may be provided within the image processing module. The feature information in the image data may further include motion picture information PQBYP indicating whether a current image frame corresponding to the image data is a motion video image frame. If the moving picture information indicates that the current image frame corresponding to the image data is a moving video image frame; and controlling the moving picture processing module to continuously process the received image data. And if the moving picture information indicates that the current image frame corresponding to the image data is not a moving video image frame, controlling the moving picture processing module to pause processing the received image data. I.e., the motion picture information PQBYP is equal to 1, the functions of the MEMC and OD can be turned off to further reduce power consumption. Because the front-end transmission source often has a non-moving picture when not playing video but does not play video for a part of time, for example, when the video decoding device sends a series of switching of photos instead of moving video, the moving picture information PQBYP is set to 1 in the sent image data, and at this time, the TCON board can be made to turn off two image processing modules with higher power consumption, namely MEMC and OD.
Further, the power consumption adjustment module DAP may include an ACQ (acquisition data) unit, a DPW (data processing and writing) unit, and a CTRL (Controller) unit. In one embodiment, the data processing flow of the power consumption adjustment module may be as shown in fig. 4, and includes the following steps:
in step S401, the ACQ unit continuously reads image data containing characteristic information.
In step S402, the ACQ unit parses the image data and separates the feature information to the CTRL unit.
The ACQ unit reads the image data from the data receiving module, analyzes the image data, separates the characteristic information from the image data, and transmits the characteristic information to the CTRL unit. For example, the ACQ unit acquires the feature information STATIC from Data [24] of Byte3 after parsing the image Data.
In step S403, the CTRL block determines whether STATIC is equal to 0; if yes, go to step S404; if not, go to step S405;
and step S404, determining that the image data is valid, and sending the image information in the image data to the DPW unit by the ACQ unit, processing the image information by the DPW unit and updating the image information to the image cache module.
In step S405, it is determined that the image data is invalid, and the ACQ unit discards the image data.
If STATIC is equal to 0, the CTRL unit determines that the image data is valid, and controls the ACQ unit to update the image data to an image buffer module, also called dynamic random access memory DDR2, through the control module mux2, where DDR2 is located at the rear end of the power consumption adjustment module, and is used to buffer image information of one frame. If STATIC is equal to 1, the image data is invalid data (still image), and the image cache module is not updated.
Meanwhile, the CTRL unit may also control the corresponding image processing module according to characteristic information (such as STATICGL, enable, or PQBYP) in the image data, and select the Disable or Bypass corresponding image processing module according to a specific value of the characteristic information, so that the TCON chip is in a semi-sleep state, thereby greatly reducing the power consumption of the entire chip.
In some embodiments, of the four pieces of feature information, feature information STATICGL, ble, and PQBYP are independently present, and feature information STATIC is used to determine validity of data, and feature information STATICGL and ble are valid only when feature information STATIC is present. Each of the above features is stored by one Bit, and may be stored by multiple bits of one or more bits of pixel data if complex features are present. For example, the feature information PQBYP can be decomposed into two feature information, respectively MEBYP and ODBYP. The MEBYP is used for indicating whether the MEMC module needs to be closed or skipped, and the ODBYP is used for indicating whether the OD module needs to be closed or skipped.
Specifically, the data processing flow of the CTRL unit of the power consumption adjustment module may be as shown in fig. 5, and includes the following steps:
in step S501, the CTRL unit receives the characteristic information transmitted by the ACQ unit.
In an embodiment, after the DAP receives the data, the ACQ unit detects whether feature information exists at each pixel point of the image, and if so, separates the feature information from the pixel data and transmits the feature information to the CTRL unit. For example, feature information STATIC is located at Byte3 Data [24], feature information STATICGL is located at Byte3 Data [25], feature information IMBLE is located at Byte3 Data [26], and feature information PQBYP is located at Bit after Byte3 Data [26 ]. When the characteristic information STATIC is equal to 1, a certain pixel point of the current display image is STATIC and unchangeable in a certain future time, and when the characteristic information STATIC is equal to 0, the pixel point is non-STATIC; when the feature information STATICGL is equal to 1, it indicates that a frame of image to be transmitted is static and unchangeable in a certain time in the future, and when it is equal to 0, it indicates that it is not static; when the characteristic information IMBLE is equal to 1, the image input by the front end is static and can be kept for a long time; when the characteristic information PQBYP is equal to 1, it indicates that the image data input at the front end does not need to be processed by the MEMC module and the OD module.
Step S502, the CTRL unit judges whether the characteristic information PQBYP is equal to 1; if yes, step S503 is executed, and if no, the process is ended.
Step S503, close or skip the corresponding PQ module.
When a video sending source analyzes a sent image according to a currently displayed image scene without needing certain image quality module processing of TCON, for example, when the front-end sending source is a series of switching of photos but not a moving video, characteristic information PQBYP, such as OD and MEMC, is added into sent image pixel data, the characteristics information ODBYP and MEBYP respectively correspond to the characteristic information PQBYP and the MEBYP, when the PQBYP is detected to be equal to 1, the DAP keeps the image data updated and simultaneously closes the functions of the MEMC and the OD, and the method is also very effective for reducing power consumption in practical use, because the front-end sending source has a part of time for not playing the video and many times for not playing the video, the TCON can close the two image processing modules with high power consumption.
Step S504, the CTRL unit judges whether the characteristic information STATIC is equal to 1; if yes, step S505 and step S506 are executed, and if no, the process is ended.
Step S505, the CTRL unit determines whether the characteristic information STATICGL is equal to 1; if yes, step S506 is executed, and if no, the process is ended.
Step S506, the corresponding image processing module is skipped or closed.
When the video decoding module analyzes that the sent image is in the future for a certain time according to the currently displayed image scene, namely when continuous multiframes of the image are kept unchanged, the feature information STATIC and STATIC are added. After the DAP receives the data, if the feature information STATICGL is detected to be equal to 0, an image processing module in front of the DAP is controlled to continue processing after the next frame of image comes, the processed image information is stored in another image buffer DDR1 module, and an image signal is output by a data control signal output module TX based on DDR1 and DDR 2. If it is detected that the feature information STATIC and STATIC are both equal to 1, it is determined that the subsequently incoming image data is no longer changing, so that the data update to the DDR2 is stopped, while the CTRL unit controls the image processing module in front of the DAP to be no longer processed until the next frame image comes. Not only do these image processing modules shut down or skip briefly, but because they take up more DDR bandwidth, their use of DDR1 bandwidth can be reduced. By the method, the system can realize dynamic adjustment of power consumption, thereby effectively reducing the power consumption of the system.
Step S507, the CTRL unit determines whether or not feature information imbable is equal to 1; if yes, go to step S508, if no, end.
In step S508, the TX refresh rate is decreased, and the RX signal detection frequency is decreased.
When the video transmission source analyzes the transmitted image according to the currently displayed image scene for a long time in the future and the front-end transmission source may be in a standby state thereafter, the transmission of data is stopped in order to save its own power consumption, the feature information STATIC and enable is added. After receiving the image data, if the DAP detects that the feature information STATIC and enable are both equal to 1, the DAP will increase the control of RX and TX based on the above processing, and notify RX to prepare for no data input in the future. If the RX is out of lock, the RX signal detection frequency is reduced, and since the RX signal detection frequency is displayed as a static image, human eyes are more sensitive to the frequency of a dynamic image and are not sensitive to the static image, the TX refresh rate can also be reduced. Keeping the front-end video transmission source in standby for stopping transmitting data greatly reduces the overall power consumption of the system.
