[0002] Currently, in the process of digital image processing, image noise reduction, scaling, color adjustment, contrast adjustment, brightness adjustment, frame rate improvement and other technologies have become the basic requirements of current video processing chips. With the rapid development of 4K and 8K resolution technology, more requirements are put forward for the specifications of video processing chips. For example, in addition to supporting traditional DI, 3D and other technologies, the current 4K set-top box also needs to support HDR, WCG and other technologies.

Higher technical specification requirements put higher requirements on the processing capacity and power consumption of the chip.

[0048] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without any creative effort fall within the protection scope of the present application.

[0049] In practical applications, the post-stage display module usually needs to process different input sizes of width and height and different output resolution information, and when the data amount of the input video frame information is large, a relatively high clock is usually required to read data from the DDR, and when the output resolution is high or the frame rate is high, the requirement for the pixel clock is also higher. If a higher clock is used to read a small amount of video frame data in software design, the video frame can be normally displayed and output in function, but compared with reasonable clock configuration, the display power consumption is increased.

[0050] The post-stage display module usually needs to process compressed data and uncompressed data, and the path is also divided into compressed path and uncompressed path. The 4K set top box also has the processing of the HDR module, and the commonly used path also has the scaling module and the write-back memory module at each stage. If all the paths are enabled regardless of the scene requirement, it means that the post-stage display module is working, the load is relatively large, and the display power consumption is also greatly increased.

[0051] In view of the above problems, the application provides a control method of a post-stage display module, which reconfigures the post-stage display module according to actual source configuration parameters and output configuration parameters of a to-be-output video, enables only the required working circuit, and closes other irrelevant circuit units, so that the total power consumption of the post-stage display module is reduced while meeting the display requirements of users, the resource occupation is reduced, and the service life of the post-stage display module is improved.

[0052] The embodiment of the application discloses a control method of a post-stage display module, as shown in Figure 1 The control method comprises the following steps:

[0053] S1: acquiring source configuration parameters of a to-be-output video;

[0054] S2: acquiring a user configuration instruction or output configuration parameters corresponding to an output device;

[0055] S3: determining working circuit units corresponding to the source configuration parameters and / or the output configuration parameters in the post-stage display module;

[0056] S4: enabling the working circuit units and closing other circuit units of the same type as the working circuit units in the post-stage display module.

[0057] It can be understood that the purpose of the embodiment is to dynamically control the working state of the circuit units in the post-stage display module, enable only the related working circuit units, and close other circuit units of the same type as the working circuit units which do not participate in the display work, so that the total power consumption of the post-stage display module is reduced while ensuring that the to-be-output video can be displayed according to the corresponding configuration.

[0058] Specifically, as shown in Figure 2As shown, the path of the video to be output in the post-stage display module generally includes: a decoder decodes the video to be output to obtain frame data, the frame data passes through a certain data parsing output unit, then passes through an HDR unit for processing, passes through a pre-scaling unit for processing, and then enters a certain memory dynamic control unit, after which the frame data sequentially passes through a plurality of image processing units, and finally is output by a display output terminal. The data parsing output unit here includes a compression unit and a non-compression unit, the non-compression unit includes an interlaced unit and a progressive unit; the pre-scaling unit can reduce the size of the frame data, but cannot enlarge it; the memory dynamic control unit includes a write-back unit and a non-write-back unit, and can also include a memory release unit; the image processing unit specifically includes an image scaling unit, an image effect unit, etc.; the display output terminal includes an HDMI output terminal and / or a CVBS output terminal.

[0059] In the original technical method, all units existing in the post-stage display module are in an enabled state, regardless of whether they are in the path of the frame data of the video to be output, and run at the highest working clock, so that the power consumption of the post-stage display module is high, causing waste. After obtaining the frame data through the decoder, the embodiment first implements a control method to determine the working circuit units through the source configuration parameters and the output configuration parameters, that is, to determine the frame data transmission path of the video to be output, to enable only the working circuit units on the transmission path and to close other circuit units of the same type, thereby greatly reducing the total power consumption of the post-stage display module.

[0060] Specifically, step S3 in the post-stage display module determines the process of the working circuit units corresponding to the source configuration parameters and / or the output configuration parameters, including:

[0061] In the post-stage display module, the display output terminal corresponding to the output configuration parameter is determined;

[0062] And / or, in the post-stage display module, the working clock corresponding to the source configuration parameter and the output configuration parameter is determined;

[0063] And / or, in the post-stage display module, the data parsing output unit corresponding to the source configuration parameter is determined;

[0064] And / or, in the post-stage display module, the memory dynamic control unit corresponding to the source configuration parameter and the output configuration parameter is determined.

[0065] It can be understood that the circuit units involved in the embodiment can be divided into display output terminals, working clocks, data parsing output units, memory dynamic control units, etc. according to the major categories. The post-stage display module can also include other types of circuit units, which are not specifically limited here. Step S3 determines one or more working circuit units in each type of circuit unit, and other circuit units of the same type can be closed during the display of the video to be output, thereby avoiding resource waste and excessive energy consumption.

[0066] The embodiment of the application discloses a control method of a post-stage display module, comprising: acquiring source configuration parameters of a video to be output; acquiring user configuration instructions or output configuration parameters corresponding to an output device; in the post-stage display module, determining working circuit units corresponding to the source configuration parameters and / or the output configuration parameters; enabling the working circuit units, and closing other circuit units of the same type as the working circuit units in the post-stage display module. According to actual source configuration parameters and output configuration parameters of the video to be output, the post-stage display module is reconfigured, only the working circuit units needed are enabled, and other irrelevant circuit units are closed, so that the total power consumption of the post-stage display module is reduced, resource occupation is reduced, and the service life of the chip of the post-stage display module is improved while meeting the display requirements of the user.

[0067] The embodiment of the application discloses a specific control method of a post-stage display module, and compared with the previous embodiment, the embodiment further describes and optimizes the technical scheme. Specifically,

[0068] In the post-stage display module, the process of determining the display output terminal corresponding to the output configuration parameters specifically comprises:

[0069] According to the display output terminal parameters in the output configuration parameters, it is determined that the display output terminal in the post-stage display module is specifically an HDMI output terminal or a CVBS output terminal.

[0070] It can be understood that according to the display output terminal parameters in the output configuration parameters of the output device, namely the display device, the display output terminal supported by the output device can be obtained, and the type of the display output terminal specifically includes an HDMI output terminal and / or a CVBS output terminal; according to the display output terminal parameters in the output configuration parameters of the user configuration instructions, the display output terminal corresponding to the user configuration instructions can be obtained, and the type of the display output terminal specifically includes an HDMI output terminal and / or a CVBS output terminal. Generally, the priority of the display output terminal parameters supported by the output device is higher, a plurality of display output terminals correspond to different priorities respectively, the display output terminal parameters of the output device and the display output terminal parameters of the user configuration instructions are compared, when there is an intersection between the two, if the intersection corresponds to a unique display output terminal, the display output terminal corresponding to the intersection is directly determined, if the intersection includes a plurality of display output terminals, the display output terminal with higher priority is selected according to the system default setting, and when there is no intersection between the two, the display output terminal parameters of the output device are used as the criterion. Further, after the display output terminal is determined, the display output terminal is enabled, and if the display device still has other display output terminals, the other display output terminals in the display device are closed.

[0071] In the post-stage display module, the process of determining the working clock corresponding to the source configuration parameter and the output configuration parameter comprises:

[0072] According to the frame data information in the source configuration parameter and the output resolution information in the output configuration parameter, the level of the working clock in the post-stage display module is determined.

[0073] The frame data information in the source configuration parameter comprises the frame size, frame rate, data format and other information of the video to be output. According to the frame data information and the output resolution information, a corresponding display path, i.e. frame data transmission path, is selected. Each display path can calculate the minimum frequency of the working clock that allows each working circuit unit to work according to the hardware parameters in the post-stage display module, the frame data information and the output resolution information. Specifically, it comprises the clock of the corresponding top / sram / mcm. In addition, the working clock under different configuration conditions can also be calculated and set in advance and stored in the form of a table. For example, the calculated clock of the 4K video to be output is 345MHz, and the calculated clock of the FHD video to be output is 196MHz. When the specific control method is applied, only the table needs to be looked up to determine the level of the working clock required by each working circuit unit under the current condition. Further, after the level of the working clock is determined, the working clock of this level is enabled, and the circuit unit of the clock of other levels is closed. Compared with reading data at the maximum clock, the accurate working clock consumes less power under the premise of meeting the display function. In the post-stage display module, the process of determining the data analysis output unit corresponding to the source configuration parameter comprises:

[0074] The frame data information in the source configuration parameter is analyzed, and the type of the frame data information is determined.

[0075] When the frame data information is compressed data, the data analysis output unit is determined to be a compression unit.

[0076] When the frame data information is non-compressed data and is interlaced data, the data analysis output unit is determined to be an interlaced unit.

[0077] When the frame data information is non-compressed data and is non-interlaced data, the data analysis output unit is determined to be a progressive unit.

[0078] It can be understood that the frame data information is different, and the required data analysis output unit is also different. Usually, all data analysis output units in the subsequent display module are enabled, but only one data analysis output unit is in working state, and the remaining working circuit units are only wasting resources. Therefore, under the premise of dynamically reducing power consumption, the embodiment determines the data analysis output unit corresponding to the frame data information, thereby closing other data analysis output units outside the data analysis output unit. Specifically, if the data analysis output unit is a compression unit, only the compression unit is enabled, and the same type of interlaced unit and progressive unit are closed; if the data analysis output unit is an interlaced unit, only the interlaced unit is enabled, and the same type of compression unit and progressive unit are closed; if the data analysis output unit is a progressive unit, only the progressive unit is enabled, and the same type of interlaced unit and compression unit are closed, thereby realizing effective power consumption limitation.

[0079] Usually, after the frame data information is processed by the determined data analysis output unit, it is sent to the HDR unit for processing. After that, the frame data information will be sent to the scaling unit and other image processing units for processing, and finally output to the display output terminal. It can be understood that if the output device also supports HDR processing, the HDR unit can be omitted in the subsequent display module of the embodiment, thereby saving the power consumption of the HDR unit in the subsequent display module. Similarly, the control method of the embodiment can also consider whether the frame data information must pass through the pre-scaling unit and / or image effect unit. If not, the unnecessary circuit unit can be omitted to reduce the access frequency to the DDR and the power consumption.

[0080] Similarly, referring to Figure 3 In the subsequent display module, the process of determining the memory dynamic control unit corresponding to the source configuration parameter and the output configuration parameter includes:

[0081] S11: determining the scaling ratio of the video to be output according to the video input size in the source configuration parameter and the video output size in the output configuration parameter;

[0082] S12: judging whether the video to be output needs to be written back to the memory according to the scaling ratio;

[0083] S13: if yes, determining that the memory dynamic control unit is a write-back unit;

[0084] S14: if no, determining that the memory dynamic control unit is a non-write-back unit.

[0085] In order to further reduce resource consumption and dynamically control resources, after determining that the memory dynamic control unit is a write-back unit, the method further includes enabling the memory release unit to release the memory applied for offline or the memory corresponding to the resource to be destroyed.

[0086] It can be understood that when it is determined that the memory dynamic control unit is a write-back unit, the write-back unit and the memory release unit are enabled, and the non-write-back unit is closed; when it is determined that the memory dynamic control unit is a non-write-back unit, the non-write-back unit is enabled, and the write-back unit and the memory release unit are closed.

[0087] It can be understood that the determination of the memory dynamic control unit corresponds to a dynamic adjustment strategy of the memory power consumption of the subsequent display module, as shown in Figure 4 The strategy specifically includes:

[0088] The subsequent display module receives frame data of the previous module and output coordinate information set by a user, obtains input and output sizes and a scaling ratio, determines whether to use a write-back unit or a non-write-back unit according to the scaling ratio to dynamically apply memory for processing, and dynamically decides whether to release the memory after display output. Data is processed by the non-write-back unit as much as possible in an online mode to avoid the application of memory on a scaling path; when data on the scaling path must be processed in an offline mode for data write-back, memory is applied according to the actual frame size of the scaling write-back to avoid the direct application of maximum memory and cause resource waste, and then the write-back unit is used for processing; in the scene switching process in actual application, the data on the display path is converted from the offline mode to the online mode, and the memory release unit is used to release the memory applied in the offline mode last time to dynamically recycle the memory; when data on the scaling path is processed in the offline mode to apply memory, if system resources are insufficient and the required write-back memory cannot be applied, the write-back strategy can be dynamically adjusted to meet the data demand; similarly, the software implementation of the subsequent display module may involve a part of resource management, such as the management of queues or threads, and the application of resource memory, and in the actual implementation process, the part of resources is also dynamically managed, memory is allocated when resource demand occurs, and memory is released after resource destruction, so that the maximum use of memory resources is realized.

[0093] An action module 4 is configured to enable the working circuit unit and close other circuit units of the same type as the working circuit unit in the subsequent display module.

[0094] The application reconfigures the post-stage display module according to actual source configuration parameters and output configuration parameters of the video to be output, enables only the working circuit required, and closes other irrelevant circuit units, so as to meet the display requirements of the user while reducing the total power consumption of the post-stage display module, reducing resource occupation, and prolonging the service life of the chip of the post-stage display module.
