Abstract
The invention discloses a TV set, comprising digital signal processing module and analog signal processing module as well as an MCU, where the MCU is used to determine wheter an input signal is an digital or analog signal and controls the digital or analog signal processing module to process the input signal according to the determined result. And it can play back digital and analog TV signals only by one MCU, saving costs for TV set producers. Besides, it is convenient for users to use because only a set of software is used and only a remote controller is required by only adopting an MCU.
Description
Technical field
The present invention relates to television set, particularly the television set of energy receiving digital signals and analog signal.
Background technology
At present, TV signal does not also all convert digital signal to, and the TV signal that some TV stations send is an analog signal, and the TV signal that other TV stations send is a digital signal.For the user who has bought simulated television, buy a set-top box for watching Digital Television to increase again.For the convenience of the user, television manufacturer begins to produce the television set of energy receiving digital signals and analog signal.But as shown in Figure 1, the television set of existing receiving digital signals simultaneously and analog signal, only the software and hardware of the software and hardware of set-top box and television set is simply combined, generally adopt television set as main control end, the software and hardware of set-top box is as an input channel of television set.Though this has realized receiving digital signals and analog signal on a television set, only be that set-top box has been put into the television set the inside from the television set outside, not the all-in-one on the complete meaning.And the television set of this energy receiving digital signals and analog signal need adopt two cover softwares, two MCU of need use.Such television set need dispose two remote controllers, controls set-top box and television set in the television set respectively.Even two remote controllers are lumped together from hardware, the user uses also very complicated.
The deficiencies in the prior art part is: for the user, need operate two remote controllers when using the television set that has energy receiving digital signals and analog signal now, the operation more complicated.Though perhaps use a remote controller, remote keying is a lot, essence is that the button of two remote controllers has been accomplished together, and the user makes troubles for the user in the use like this.For television manufacturer, produce existing can receiving digital signals and the television set of analog signal need adopt and want two MCU, cost is higher.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of television set that can watch digital signal and analog signal is provided, and only adopts a MCU, to make things convenient for the user, to save cost.
Technical scheme of the present invention is summarized as follows:
Compared with prior art, effect of the present invention is as follows: television set of the present invention comprises digital signal processing module and analog module; Also comprise a MCU, this MCU is used to judge that the signal of input television set is digital signal or analog signal, according to result of determination control figure signal processing module or analog resume module corresponding signal.Like this, the present invention only adopts a MCU just energy playing digital television signal and anolog TV signals, for the TV business men has been saved cost.Simultaneously, because the present invention only adopts a MCU, software also has only a cover, and a remote controller control of corresponding also need television set is user-friendly to.

Embodiment
Also the present invention is described in further detail in conjunction with the accompanying drawings below by specific embodiment.
Embodiment 1:
As shown in Figure 1, a kind of television set comprises digital signal processing module 1, analog module 2, a MCU3.MCU3 judges that the signal of input television set is digital signal or analog signal, according to result of determination digital signal is sent to digital signal processing module 1 or analog signal is sent to analog module 2 and control figure signal processing module 1 or analog module 2 processing corresponding signals.
MCU3 disposes corresponding control interfaces according to the control mode of each module, and then controls each module.As shown in Figure 2, the control method of MCU3 is as follows: the first step: behind the television boot-strap, MCU3 and each module are carried out initialization.Second step: MCU3 judges whether that event occurs.The 3rd step: if the result who judges is that event occurs, MCU3 just controls each resume module corresponding event, returns for second step; If the result who judges does not have incident to take place, just returned for second step.
Analog module 2 comprises simulation tuner 21, picture decoding module 22, acoustic processing module 23, and the output of simulation tuner 21 links to each other with sound processing module 23 with picture decoding module 22 respectively.
Digital signal processing module 1 comprises digital tuner 11, demodulator 12, demultiplexing module 13, decoder module 14 and the D/A converter module 15 that links to each other successively.Wherein, the output of D/A converter module 15 links to each other with acoustic processing module 23.
Television set of the present invention also comprises screen and shows adjusting module 4 (scaler), screen 5 and loud speaker 6; Screen shows the video output of adjusting module 4 input analog modules 2, digital signal processing module 1, and screen 5 input screens show the output of adjusting module 4, the audio frequency output of loud speaker 6 input analog modules 2.Above-mentioned screen shows adjusting module 4, screen 5 and loud speaker 6 and is all controlled by MCU3.
The course of work of the present invention is as follows:
The first step: when TV signal input television set, MCU3 judges whether the TV signal of input is digital television signal.
Second step: if judged result is a digital television signal, MCU3 control figure TV signal converts intermediate-freuqncy signal to through digital tuner 11 and demodulates transmission (TS) stream through demodulator 12 again and carry out mpeg decode through decoder module 14 again, and wherein video data is through playing back on screen 5 after adjusting module 4 is adjusted sizes through shielding to show after the decoding again; Wherein voice data converts analogue audio frequency to through D/A converter module 15 again through decoding, after acoustic processing module 23 is handled is playing back by loud speaker 6.If judged result is not a digital television signal, MCU3 control anolog TV signals convert intermediate-freuqncy signal to through simulation tuner 21, and wherein video data plays back on screen 5 after adjusting module 4 is adjusted size through shielding to show through 22 decodings of picture decoding module again; Wherein voice data is handled through acoustic processing module 23 and is played back by loud speaker 6.
Embodiment 2:
At the digital signal of encrypting, the present invention can set up smart card 16.The output of these smart card 16 input demodulators 12, the output of demultiplexing module 13 input smart cards 16.Smart card 16 comprises descrambler, is used for the digital signal deciphering to encrypting.Like this, just guaranteed to have only authorized user ability watching encrypted TV programme.
