Description of drawings
Fig. 1 is the structural representation of a preferred embodiment of the present invention.
Embodiment
The present invention is by making up two tuners, carries the PVR module, and recordable TV set platform of development and Design can be implemented in when watching a cover broadcast TV program, and an other cover broadcast TV program is recorded on the backstage, to better meet the TV user demand.
As shown in Figure 1, from antenna or next radiofrequency signal (the Radio Frequency of CATV transmission, be called for short RF) (by China's color television standard, the frequency range of RF is the high-frequency signal of 48.5～870MHz, it comprises signals such as image, colourity, sound accompaniment, wherein sound carrier frequency is than the high 6.5MHz of vision carrier frequency, and color carrier frequency is than the high 4.43MHz of vision carrier frequency) be divided into two-way by distributor 1 and be defeated by first tuner 2 and second tuner 12 respectively; First tuner 2 and second tuner 12 are exported intermediate-freuqncy signal respectively and are given each self-corresponding first Surface Acoustic Wave Filter 3 and second Surface Acoustic Wave Filter 13; After carrying out sound table Filtering Processing by first Surface Acoustic Wave Filter 3 and 13 pairs of intermediate-freuqncy signals of second Surface Acoustic Wave Filter, export the first intermediate frequency amplification treatment circuit 4 and the second intermediate frequency amplification treatment circuit 14 respectively to, signal is demodulated into composite video broadcast singal (Composite Video BroadcastSignal, CVBS), the first intermediate frequency amplification treatment circuit 4 and the second intermediate frequency amplification treatment circuit 14 are also exported base band voice signal (AUDIO) or accompanying sound intermediate frequency signal (Sound Intermediate Frequency simultaneously, be called for short SIF), these signals are defeated by the TV main circuit and are carried out Voice ﹠ Video processing (as decoding and image and voice optimization); And first tuner 2 and second tuner 12 are set to different address, and all pass through I
2C and 5 communications of TV main circuit; The first intermediate frequency amplification treatment circuit 4 and the second intermediate frequency amplification treatment circuit 14 also are set to different address, and all pass through I
2C and 5 communications of TV main circuit, thus make TV main circuit 5 can control first tuner 2 or second tuner 12, the first intermediate frequency amplification treatment circuit 4 or the second intermediate frequency amplification treatment circuit 14 separately.
The TV main circuit 5 that the present invention adopts uses the difference of chip, and it can select following two kinds of different connected modes:
The first intermediate frequency the amplification treatment circuit 4 and second intermediate frequency amplification treatment circuit 14 all exports the CVBS signal and the SIF signal sends TV main circuit 5 to, this requires TV main circuit 5 to have the ability of handling two-way SIF signal.
Perhaps, 4 outputs of the first intermediate frequency amplification treatment circuit are exported CVBS signal and SIF signals and are sent TV main circuit 5, the second intermediate frequency amplification treatment circuits, 14 output CVBS signal and AVDIO signals to and send TV main circuit 5 to.
When the user wants program recording, can set in advance the source of recording (TV1, TV2, AV etc.).TV main circuit 5 is handled the current signal that will watch of user through decoding, optimization, convergent-divergent etc. after, output video component signal to display 5 shows that the output audio component signal is to audio output unit 7 (it comprises power amplifier 71 and loudspeaker 72); The signal that to record the source simultaneously on the backstage is treated, exports (present most TV chips all have this function) to PVR module 8 by AV.
Specifically, for example, the user thinks a current channel A who watches TV programme, simultaneously want to record the TV programme of another channel B again, then it can be made as TV1 with television set current demand signal source, be set to TV2 recording source selection place then, and the channel (program number) of TV2 is set, at this moment following processing is carried out in television set inside: TV main circuit 5 passes through I
2The total line traffic control of C with the receive frequency point of first tuner 1 be tuned to the user want the channel A frequency points corresponding of watching, the first intermediate frequency amplification treatment circuit, the 4 output CVBS1 and the audio signal SIF1 of signal source TV1 passage give TV main circuit 5, display 6 explicit users are wanted the picture of the TV programme of watching, the sound of audio output unit 7 output TV programme; Simultaneously, TV main circuit 5 control is tuned to the frequency that the user wants the channel B that records with the reception frequency of second tuner 12, give TV main circuit 5 with the second intermediate frequency amplification treatment circuit, the 14 output CVBS2 and the audio signal SIF2 of signal source TV2 passage, TV main circuit 5 after treatment, CVBS2 and audio signal SIF2 are exported to PVR module 8 by AV, receive input signal and record by PVR module 8.
In the time will playing recording signal, TV main circuit 5 sends the recorded file play instructions to PVR module 8, and PVR module 8 reads file on memory 84 or the external memory storage 9 internally and the decoding back carries out playback process for TV main circuit 5 by certain form loopback.For example, the file of storage is the MPEG-2 form, and PVR module 8 converts thereof into the YPbPr signal and sends the TV mainboard back to.Because general television set itself also has the YPbPr input; When YPBPR input (ADC input) mouth of TV main circuit 5 is not enough, a selector switch 10 can be set, with the YPbPr of former YPbPr and sound thereof and 8 outputs of PVR module and sound thereof as the input of selecting, which signal the switching of TV main circuit 5 control selector switches 10 decides to enter TV main circuit 5: when needs are play recording signal, selector switch 10 is switched to the YPbPr output of PVR module 8, make its signal can send to TV main circuit 5, this signal exports display 6 to after handling through TV main circuit 5, export voice signal to power amplifier 71, by loudspeaker 72 outputs.
To sum up, the present invention has realized when playing the TV programme of a channel television set, can the backstage records the TV programme of another one channel, provides great convenience to the user; And the present invention realizes simply can being widely used in the television set of the various PVR of having modules.
