Abstract

The invention discloses a video data processing method and system. In the above method, a video processor receives video data streams from one or more input devices; the video processor receives video data streams from one or more input devices; A display processor performs segmentation and encoding processing on the video data stream, and encapsulates the calibration time stamp into each data packet after segmentation and encoding processing. The calibration time stamp is used to enable one or more display processors to Each data packet of the video is synchronously displayed on the TV splicing wall. The calibration time scale is obtained after the video processor performs segmentation and encoding processing on the video data stream, and is obtained after calibration according to the current time scale of the server; the video processor will be divided into The encoded packets are sent to one or more display processors. In this way, the accuracy of synchronous display of the distributed large-screen control system in the case of a large number of cut screens on the TV splicing wall is improved, and the user experience is improved.

Description

Technical field [0001] The present invention relates to the field of video display, in particular, to a method and system for processing video data. 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. The video signals and / or audio signals are interconnected through peripheral components (PeripheralComponent Interconnect, referred to as PCI for short) inside the system. ) Or a large-screen controller that simulates switching for transmission is the mainstream of screen control technology on the market. [0003] However, the use of centralized large-screen control has the following disadvantages: [0004] (1) The centralized large-screen control system usually uses acquisition cards to access signals. The signal access capability needs to be restricted by the acquisition card capabilities, the number of chassis slots, bus bandwidth and other factors, and its si...
