Abstract

The invention discloses a method, device and system for playing high-definition television programs based on satellite signals; wherein, the method includes: the TV set-top box demodulates the received satellite combined signal to obtain the demodulated TV signal; Extract the corresponding TV channel program signal from the tuned TV signal; judge whether the resolution parameter of the corresponding TV channel program signal meets the high-definition playback condition; if not, then obtain the audio data and time stamp in the corresponding TV channel program signal, and The audio data is cached in the audio data buffer; the network module built in the TV set-top box performs network TV video signal matching, and matches the matched network TV channel program signal that meets the high-definition playback conditions; controls the audio data in the audio data buffer based on the time stamp The audio data and the network TV channel program signal are played synchronously with high-definition TV programs. In the embodiment of the present invention, the user's demand for playing high-definition programs is met, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of high-definition television playback control, in particular to a method, device and system for playing high-definition television programs based on satellite signals. Background technique [0002] Digital satellite TV is a form of broadcast TV that uses geostationary satellites to transmit digitally encoded and compressed TV signals to the user end; there are two main methods: one is to transmit digital TV signals to the front end of cable TV, and then converted by cable TV to Analog TV is delivered to the user's home. Another way is to directly transmit the digital TV signal to the user's home: Direct to Home (DTH) way; compared with the first way, the DTH way satellite transmits more power and can be received by a smaller antenna, which is enough for ordinary families Use; at the same time, it can directly provide user authorization and encryption management, and carry out advanced TV services such as d...
