Abstract

The invention provides an integrated digital high-definition television application platform adopting an IP (Internet Protocol) technology, which comprises a signal reception sub-system, a signal integration subsystem and a signal conversion subsystem. The signal reception subsystem receives signals of standard-definition or high-definition programs of a satellite television or a wired television and converts a signal source into clear stream digital television signals. The signal integration subsystem combines the clear stream digital television signals settled by the signal reception subsystem into a digital signal. The signal conversion subsystem converts the digital television signals into two modes respectively and transmits the signals. The integrated digital high-definition television application platform adopting the IP technology fully utilizes and optimizes inner wired television and network system resources of hotels and business buildings, so that digital television signals and network television signals with high quality and high code stream are efficiently and smoothly transmitted and played in a local area network.

Description

technical field [0001] The present invention relates to the playing field of digital TV and IPTV (Internet Protocol Television, interactive Internet TV), especially a playing system combining the two and transmitting them synchronously. Background technique [0002] IPTV, or Interactive Network Television, is a brand-new technology that utilizes broadband cable TV network and integrates Internet, multimedia, communication and other technologies to provide home users with various interactive services including digital television. Users can enjoy IPTV services in two ways at home: (1) computer, (2) network set-top box + ordinary TV. It can well adapt to the rapid development trend of today's network and make full and effective use of network resources. IPTV is not only different from traditional analog cable TV, but also different from classic digital TV. Because both traditional and classic digital TV have the characteristics of frequency division system, timing, and one-wa...
