The invention belongs to the high-definition digital television technical application field, in particular relates to a centralized high-definition digital television providing method supporting multiple program sources and coding modes and a system. The system comprises a management control central module, wherein, a program source preprocessing module, a local storage server, a centralized decoding matrix module and a system request communication module are connected with the management control central module respectively; the program source preprocessing module is connected with the centralized decoding matrix module; the centralized decoding matrix module is connected with a radio frequency modulation translation connection module; the management control central module is also connected with the system request communication module; the system request communication module is connected with client request communication equipment. The system allows a user to watch better high-definition television programs without mounting a set-top box, and simultaneously can support the user to request channels and request programs.
Description
technical field [0001] The invention belongs to the application field of high-definition digital television technology, and in particular relates to a centralized high-definition digital television providing method and system supporting multiple program sources and encoding methods. Background technique [0002] The conversion from analog TV to digital TV is a major technological advancement in the dissemination of audio and video information. Digital TV has strong anti-interference ability and can restore clearer programs after remote transmission. However, after the audio and video signals of TV programs are digitized, the original information will occupy a considerable bandwidth. For example, a standard definition TV signal with a resolution of 720*576 will occupy a bandwidth of 167 Mbps after digitization, while a high definition TV signal with a resolution of 1920*1080 will occupy a bandwidth of 1.18 Gbps after digitization. In order to transmit such a large amount of ...
