Television receiving system in double modes of digital television terrestrial multimedia broadcasting and internet

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.
