Embodiment Construction

[0030] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] First, the principle diagram of the multi-channel television receiver will be described. Such as figure 1 As shown, the system targets all existing broadcast TV signals, including FM, AM broadcast, cable TV signal, terrestrial TV signal, satellite TV signal, analog signal, digital signal, and so on. All these radio and television signals pass through a digital tuner to obtain an intermediate frequency signal, and the intermediate frequency signal is demodulated and sent to the decoder, and then input to the back end. Due to the difference of signals, different signals require different tuners, demodulators, and decoders. For traditional analog TV, the digital tuner is tuned by the microcontroller MCU. The full TV signal generated by tuning is driven by the line and field to output the video signal from the p...

Abstract

The associative list associates more than two TV broadcast channels; wherein, the associated channels have same program content; when user watches TV, he can read channel information through the associated channels, and switches the channel according to the associative information such that the user can select the signal source with best signal quality from multi signal sources.

Description

technical field [0001] The invention relates to the management of radio and television channels, in particular to a method for switching channels by using an association table for channels of the same program content in multiple sets of television channels. Background technique [0002] At present, with the development of technology, especially the development and popularization of digital broadcast TV technology, TV broadcast receiving devices that can be used for mobile reception are becoming more and more mature in technology. The radio and TV receiving device must not only be compatible with traditional analog signals, but also adapt to new digital signals. At the same time, it must also consider receiving satellite signals, terrestrial signals, and cable signals. In addition, with the rise of mobile TV, differences in signals in different regions will cause trouble for users. Therefore, how to find the programs you want in different signal sources and choose to broadca...
