Problems solved by technology
[0004] However, at the current technological level, the speed of CMOS integrated circuits has a limit, and the improvement of memory access speed has always lagged behind that of logic circuits, so the bandwidth of memory access is the bottleneck restricting system performance; at the same time, large-scale data writing and reading It also greatly increases the energy consumption of the system

Embodiment Construction
[0065] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0066] refer to figure 1 As shown, it is a schematic diagram of an existing ultra-high-definition video frame rate up-conversion system, which specifically includes: a video input module 11, an off-chip cache 12, an ultra-high-definition video frame rate up-conversion processing core 13, and a video output module 14; 11 Input the original video frame to the off-chip cache 12; the UHD video frame rate up-conversion processing core 13 extracts the original video frame from the off-chip cache 12, and performs a series of motion estimation, vector post-processing and internal processing on the extracted original video frame The interpolation operation generates an interpolated video frame, and finally sends ...

The embodiment of the application provides a video data processing method, applied to a video post-processing system. The method comprises the following steps: obtaining the video frame data to be processed provided by the video post-processing system; dividing the video frame data to be processed into multiple independent blocks to be compressed; grouping pixel points in a single block to be compressed to obtain groups with different priorities; and compressing the pixel points of each group according to the priority of each group. According to the video data processing method provided by the embodiment of the application, during the compression processing, the pixel points in the same block to be compressed are divided into the groups with different priorities, and the pixel points of different groups in the block to be compressed are compressed according to the groups with other priorities in the block to be compressed to ensure that when decompressing the compressed bitstream that is generated by compression, the compressed bitstream can be decompressed only based on the pixel points in the same block to be compressed without relying on other blocks to be compressed, and thus the block to be compressed can be randomly accessed.
Description
technical field [0001] The present application relates to the technical field of video processing, in particular to a video data processing method and a video data processing device. Background technique [0002] In recent years, people's subjective demand for high-quality visual enjoyment and the objective conditions of the rapid development of semiconductor technology have jointly promoted the vigorous development of the UHD TV industry. However, due to the limitation of the bandwidth of the current transmission system, UHD TV programs can only be transmitted at a lower frame rate. At the same time, the refresh rate of large-screen display devices has been greatly improved, and the video frame rate is lower than the screen refresh rate. This mismatch directly leads to image smearing, pauses, blurring, etc., and the display effect is not good. As an important video post-processing method, the video frame rate up-conversion technology can effectively increase the frame rate...
