Abstract

The invention discloses a method and system for processing video data. According to the method, a video processor receives video data streams from one or more input devices; the video processor carries out partition and coding processing on the video data streams according to one or more display processors connected to the video processor and encapsulates calibration time markers into all data packets after the partition and coding processing is carried out, the calibration time markers are adopted to enable the display processors to synchronously display all the data packets on a television spliced wall, wherein the data packets are obtained after the partition and coding processing is carried out, and the calibration time markers are obtained after calibration is carried out according to the current time marker of a server when the video processor carries out partition and coding processing on the video data streams; the video processor sends the data packets obtained after the partition and coding processing is carried out to the display processors. In this way, under the condition that the number of cut screen blocks on the television spliced wall is large, the accuracy of synchronous display of a distributed large screen control system is improved, and user experience is improved.

Description

technical field [0001] The present invention relates to the field of video display, in particular to a video data processing method and system. Background technique [0002] At present, the centralized large-screen control system refers to the input and output of video signals and / or audio signals through video cables. PCI) or a large-screen controller for analog switching and transmission, is the mainstream of screen control technology in the market at present. [0003] However, the adoption of centralized large-screen control has the following defects: [0004] (1) The centralized large-screen control system usually uses the acquisition card to access the signal. The signal access capability needs to be restricted by factors such as the acquisition card capability, the number of chassis slots, and the bus bandwidth, and its signal access capability is limited. [0005] (2) The centralized large-screen control system uses a central processing unit (Central Processing Unit...
