Hierarchical video coding method and architecture supporting multi-source data fusion

Abstract

The invention provides a hierarchical video coding method supporting multi-source data fusion. The method comprises the following steps: step 10, obtaining multi-source information of an external sensor and a synchronous video, forming a video object in the synchronous video according to a preset analysis model, and combining the multi-source information with the corresponding video object to form object description information; step 20, obtaining the allocated synchronous video, and optimizing the image in the synchronous video according to a preset optimization model to form an optimized video; and step 40, 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 multi-source information of the external sensor are coded and are synchronously combined, so that the source video forms the hierarchical code stream containing video contents and video object information. The invention further provides corresponding hierarchical video coding architecture supporting 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 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 the...
