A video hierarchical encoding method and device supporting multi-source data fusion

Abstract

The video hierarchical encoding method supporting multi-source data fusion of the present invention includes: step 10, acquiring multi-source information of external sensors and synchronous video, forming video objects in synchronous video according to a preset analysis model, and combining multi-source information with corresponding Combine video objects to form object description information; step 20, obtain the allocated synchronous video, optimize the image in the synchronous video according to the preset optimization model, and form an optimized video; step 40, perform video encoding on the optimized video, and convert the corresponding The object description information is coded and embedded into the video code stream to form a hierarchical code stream of the source video. The optimized video is encoded and synchronously combined with multi-source information from external sensors, so that the source video forms a hierarchical stream containing video content and information about each video object. It also includes a corresponding video hierarchical coding framework that supports multi-source data fusion.

Description

technical field [0001] The invention relates to a data processing method and a processing device, in particular to a display data processing method and a 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 usually 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 the c...
