Abstract

The invention provides a television receiving system in double modes of digital television terrestrial multimedia broadcasting and the internet. The television receiving system comprises a network detection module, a DTMB channel module, an internet channel module, a media pack caching module and an audio-video decoder, wherein the network detection module is used for detecting the network state of a DTMB network and the network state of the internet; the DTMB channel module is used for receiving and processing television program data of the DTMB network and caching the television program data to the media pack caching module to form first cache data; the internet channel module is used for receiving and processing television program data of the internet and caching the television program data to the media pack caching module to form second cache data; the media pack caching module is used for achieving switching between a DTMB channel and an internet channel according to the network states and a preset switching strategy and sending the first cache data or the second cache data into the audio-video decoder; the audio-video decoder is used for decoding and broadcasting the first cache data or the second cache data. Therefore, the television receiving system can optimize receiving efficiency, receiving cost, the receiving range and television viewing effects of television contents.

Description

technical field [0001] The invention relates to the technical fields of Internet TV and digital TV, in particular to a dual-mode TV receiving system of digital TV terrestrial broadcasting and Internet. Background technique [0002] DTMB (Digital Television Terrestrial Multimedia Broadcasting, digital TV terrestrial broadcasting) is one of the basic transmission methods of digital TV, and its development has a major impact on the national cultural propaganda, consumer electronics industry and future technological development trends. In 2006, the State Administration of Radio, Film and Television made its first positioning for various digital new media in the future, among which digital TV terrestrial broadcasting was clearly positioned to undertake the public welfare publicity services stipulated by the state. Two-thirds of TV users in my country, except for a few satellite digital TV users, basically rely on terrestrial analog transmission to receive TV program signals. Wir...
