Problems solved by technology

However, in practical applications, there is no guarantee that any media forwarding server will provide verification services when forwarding video data, because it may occupy more system resources of the video forwarding server
There is also no guarantee that the system clock synchronization between any two video call clients is accurate enough, because the network access points and NTP servers of different clients are different from each other
[0005] Therefore, when there is network congestion or the capacity of the set-top box system is limited, video mosaics and video delays will frequently occur, and the application layer (client) cannot accurately and reliably determine whether the video image is abnormal and deal with it accordingly

Abstract

The invention discloses a method and a system for processing video data. The method comprises the following steps: transmitting acquired video data to a compression coder for video coding; calculating the checksum of all digitally-quantified video data on an I frame; when the I frame is coded and compressed, making a timestamp; and transmitting the checksum and the timestamp to a receiving end along with the video data. The method and the system are easy and convenient to operate, and are high in accuracy. The checksum operation amount is not increased excessively, and the performance index during normal application of a video call is not influenced.

Description

technical field [0001] The invention relates to the field of video telephony fused with video information, in particular to a method and system for processing video data. Background technique [0002] The development of high-definition videophone applications is currently in full swing and has become the focus of attention of application providers, operators and users. After video playback and video surveillance applications, video call applications have gradually become a hot topic. [0003] Among them, IPTV video calls require higher resolution (above VGA), and the average value of video code stream is relatively large (above 700Kbps). Compared with IPTV video playback and global eye video surveillance, IPTV video calls have relatively low requirements for video clarity, but relatively high requirements for real-time video transmission. [0004] In order to ensure real-time performance, the network transmission of video call video data generally adopts the RTP / UDP protoco...
