Abstract

The invention discloses large screen IP (Internet Protocol) video stream access equipment which comprises an IP video access module, an IP video acquiring and decoding module and an image splicing and displaying module, wherein the IP video access module is used for accessing video streams from various IP video sources and transmitting the video streams to the IP video acquiring and decoding module; the IP video acquiring and decoding module is used for decoding various IP video streams from the IP video access module and transmitting decoded digital signals to the image splicing and displaying module; and the image splicing and displaying module is used for carrying out image splicing on the digital signals from the IP video acquiring and decoding module and displaying spliced images on a large screen. In addition, the invention also discloses an implementation method of the equipment. The large screen system of the invention can be used for directly reading the video streams from equipment such as an IP camera, a media server, a network video cassette recorder, a network video encoder, and the like and has the advantages of simple structure, stability and reliability.

Description

technical field [0001] The invention relates to a large-screen projection display system, in particular to an IP video stream access device for the large-screen display system. In addition, the present invention also relates to a method for realizing the large-screen IP video stream access device. Background technique [0002] With the wide application of IP cameras and streaming media servers in the field of large-screen projection display, how to connect digital video streams to large-screen systems and how to quickly and clearly display network videos on large screens is becoming more and more important. [0003] Two traditional IP video stream access methods are as follows: (1) First connect the IP camera with a digital-to-analog converter, convert the digital signal into an analog signal, and then access the large-screen system. [0004] (2) The video surveillance system (client computer) on the same network as the streaming media server is projected onto the large scr...
