Problems solved by technology

[0003] Existing video framing methods lack a clear and efficient message structure to define the specific process of signaling interaction, especially for different Lane numbers or high data processing volumes, and there is a lack of reasonable organizational structure and interaction specifications among the various modules of the system. The delay of each link is high, and the framing efficiency is low

Abstract

The invention discloses a video framing method. The method comprises the following steps: receiving a video framing request initiated by a first control module; generating framing interaction signaling according to the video framing request, and sending the framing interaction signaling to a related external module according to a preset message structure, so that the related external module completes video framing according to the framing interaction signaling and generates first feedback information, wherein the preset message structure comprises a channel number adaptation method selection field used for indicating a channel number adaptation method; and generating a video framing result based on the first feedback information of the related external module to the framing interaction signaling. Through the technical scheme, the interactive signaling is standardized, and the signaling interaction efficiency is improved, so that the framing efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of video processing, and in particular, to a video framing method and system. Background technique [0002] In the process of video or image transmission, the sender combines bits into frames according to certain rules, and the frame is the transmission unit, so that the receiver can correctly accept and check the transmitted frame data and improve transmission efficiency. With the continuous improvement of the resolution in the video image processing system, the number of lanes (Lane) used on the video display terminal equipment and the link rate (Link Rate, LR) on each lane are also getting higher and higher, which requires The video or image processing system can more quickly and conveniently support video framing with different numbers of Lanes. [0003] The existing video framing method lacks a clear and efficient message structure to define the specific process of signaling inter...
