The invention provides a hierarchical video code stream coding method for a time division multiplexing neural network processor. The hierarchical video code stream coding method comprises the following steps: obtaining a synchronous video, and forming a video object in the synchronous video according to a preset analysis model; obtaining the synchronous video, and optimizing the image in the synchronous video according to a preset optimization model to form an optimized video; obtaining the video object, a task processing model and the synchronous video, allocating processing resources to a task processing process of the task processing model by time division multiplexing, and carrying out corresponding task processing on the video object to form corresponding object description information; and carrying out video coding on the optimized video, coding the corresponding object description information, and embedding video code stream to form hierarchical code stream of a source video. The optimized video and the analysis and processing result information of the video objects are synchronously combined in a coding mode, so that the source video forms the hierarchical code stream containing video contents and related information of the video objects. The invention further provides hierarchical video code stream coding architecture for the time division multiplexing neural network processor.
Description
technical field [0001] The present invention relates to a data processing method and processing device, in particular to a display data processing method and processing device. Background technique [0002] Video transmission consumes a lot of bandwidth. In the field of video surveillance, real-time high-definition streams consume the most bandwidth and system processing resources. Therefore, in the prior art, the bandwidth problem is generally solved by encoding and compressing the source video to form a low-rate bit stream suitable for real-time transmission and a high-rate bit stream suitable for delayed transmission. However, only using the code rate to adapt the bandwidth cannot guarantee the real-time and reliable transmission of information in the video. When the code rate is reduced, the quality of information carried in the video is correspondingly reduced or even unusable. It is feasible to use different encoding methods to encode the information in the video and...
