Abstract
The provided method implementing video conference system based on IPTV comprises: multiple IPTV clients obtain menu data from a server stored menu data to display on display device; one client sends video conference request to other clients every with a unique IP address; when other clients accept the request and build connection, the calling client compresses and codes local audio and video data to transmit to others, and obtains data from others to display. This invention reduces cost and fit to spread widely.
Description
Technical field
The present invention relates to IPTV technology (Internet Protocol Television is called for short IPTV), more particularly, relate to a kind of video conferencing system and its implementation based on IPTV.
Background technology
IPTV is a kind of broadband cabled television network that utilizes, and integrates multiple technologies such as the Internet, multimedia, communication, and the brand-new technology of the multiple interactive services that comprises Digital Television is provided to the user.The user can have dual mode to enjoy the IPTV service at home: (1) computer; (2) network machine top box+general television set.IPTV greatly enriches people's life as a branch of Digital Television development with the characteristics of its two-way mutual.IPTV makes people teleview passively, and main is, and it can allow the service (comprising TV programme) that people select oneself on one's own initiative to be needed.
The workflow of common IPTV is as follows in the prior art: master chip CPU obtains programme information by network interface to server end and selects for the user; When the user chose concrete program (perhaps data), master chip CPU obtained this program stream data by network interface to server end; Decode the audio, video data of non-compressed encoding then by the audio decoder module, and output to display device (as television set) by the analog audio-video coding module and show.
Though existing video conferencing system scheme is by task equipment or can the building network video conferencing system by computer, make so existing video conferencing system scheme relatively specialty, cost is higher and can not spread to family of domestic consumer.
