At present, China has launched the turn over work that simulated television turns to cable digital TV, the turn over scheme that it adopts is to increase cable digital TV set-top box on original simulated television basis, the high-definition digital signal receives and decoding by cable digital TV set-top box, by simulated television output, realize that simulated television can receive and play the cabled digital signal again.Owing to set up cable digital TV set-top box, not only increase power consumption and equipment cost, it is more loaded down with trivial details to make that also circuit connects, and structure is compact inadequately, and the circuit connection that increases can cause the interference and the loss of signal, influences play quality.

The utility model content:

The purpose of this utility model is at the deficiencies in the prior art, a kind of digital simulation integrated TV is provided, can realizes that a television set watches cable digital TV and simulated television, both can reduce power consumption and equipment cost, can make more compact structure again, and guarantee play quality.

For achieving the above object, the utility model is achieved through the following technical solutions: a kind of digital simulation integrated TV, this television internal have analog signal receiver module, the tuning demodulation module of analog signal, analog signal decoder module, digital signal receiver module, the tuning demodulation module of digital signal, digital signal decoding module, digital television intelligent card deciphering module and output module; Described analog signal receiver module is electrically connected the tuning demodulation module of analog signal, and the tuning demodulation module of analog signal is electrically connected the analog signal decoder module, and the analog signal decoder module is electrically connected output module; The digital signal receiver module is electrically connected the tuning demodulation module of digital signal, the tuning demodulation module of digital signal is electrically connected the digital signal decoding module, the digital signal decoding module is electrically connected the digital television intelligent card deciphering module, and the digital television intelligent card deciphering module is electrically connected output module.

Described analog signal decoder module comprises analog signal video decode module and analog signal audio decoder module.

Described digital signal decoding module comprises digital signal video decode module and digital signal audio frequency decoder module.

Described television set is provided with remote controller, and described television set also is built-in with the digital simulation handover module of the phase adjust signal that sends with remote controller, and this digital simulation handover module is electrically connected analog signal receiver module and digital signal receiver module.

Described television set is a liquid crystal TV set.

The beneficial effects of the utility model: the SD analog signal is transported to the tuning demodulation module of analog signal through the analog signal receiver module and carries out demodulation, and then generates analogue transmission stream signal conveys and decode to the analog signal decoder module, is exported by output module again; The high-definition digital signal is transported to the tuning demodulation module of digital signal through the digital signal receiver module and carries out demodulation, and then generation digital transport stream signal conveys is decoded to the digital signal decoding module, be decrypted through Digital Television intelligence decoder module again, export by output module at last; Therefore, the utility model can realize that a television set watches cable digital TV and simulated television, both can reduce power consumption and equipment cost, can make more compact structure again, and guarantees play quality.
