In television set described in the utility model, described digital signal receiver module comprises: Channel Elements, the channel demodulation unit that is connected with described Channel Elements, the demultiplexing unit that is connected with described channel demodulation unit.Described Channel Elements is a DMB-TH digital signal receiver turning tuner.Described decoding buffer unit is a synchronous DRAM.Described program storage unit (PSU) is a flash memory.
At television set described in the utility model, also comprise: be used to store the data storage cell of small data, described data storage cell is connected with described master chip module.Described data storage cell is a static random access memory.
Implement television set of the present utility model, has following beneficial effect: can be used for DVD playing back, can receive the standard of DMB-TH GB and the digital signal of high definition, and can record the program of digital signal at any time, review when chasing after, really accomplish human oriented design, and cost is low, performance is good, because the decoding of DMB-TH digital signal and DVD are shared MPEG2 decoding units.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of television set of the present utility model.
Embodiment
The technical development of DVD and DMB-TH is very fast at present, in our country, determined the digital data transmission standard channel of surface wave, the part city has begun the digital signal emission test of DMB-TH, and the present invention is a digital stream of recording digital signal, different with present simulated television PVR scheme essence on the market, but the program recording reproduction time be they more than ten times, this machine DVD playing back simultaneously also in addition is with the DMB-TH Digital Television, DVD, PVR integrates.The source coding of DMB-TH and DVD is integrated, can be decoded by shared MPEG2, reduce cost, improve stability.But also conserve space.Realize intelligentized design.
As shown in Figure 1, in television set of the present utility model, comprise: a kind of television set, comprise: casing, be installed in the display screen 4 on the described casing, be used for vision signal output is driven the display unit 11 of display screen display frame, be installed in the DVD drive 3 in the described casing, master chip module 1, digital signal receiver module 2, hard disk PVR unit 7, decoding buffer cell 8, program storage unit (PSU) 9, DVD data-signal amplifying unit 5, with DVD driver element 6, wherein, digital signal receiver module 2, hard disk PVR unit 7, decoding buffer cell 8, program storage unit (PSU) 9 is connected with master chip module 1 respectively, and DVD drive 3 is connected to master chip module 1 by DVD data-signal amplifying unit 5 and DVD driver element 6.
Digital signal receiver module 2 comprises: DMB-TH digital signal receiver turning, channel demodulation unit and demultiplexing unit.Concrete cell descriptions of the present invention is as follows:
DMB-TH digital signal receiver turning tuner: be channel strip, as: THMSON 7578; Major function is first intermediate frequency that the RF signal is carried out the phase-locked 38MHZ of obtaining of tuning PLL, gives the Channel Elements demodulation of rear end again.The channel demodulation unit is to the take a sample TS bitstream of demodulation outputting standard of first intermediate frequency.Demultiplexing unit TS-DEMUX is to the TS bitstream demultiplexing behind the channel demodulation, obtains the PS stream of standard.
Master chip module 1: innovation part of the present invention is the PS stream that the PS behind the DMB-TH demodulation demultiplexing flows and DVD reads is share a MPEG2 decoding, the major function of master chip module 1 has: the PS stream behind the demultiplexing that the DMB-TH that (1) is sent here tuner over there sends here, decompress, the MPEG2 audio/video decoding, then decoded video data is decoded, output LVDS differential signal is directly exported and is driven display screen 4; To decoded voice data DAC, output AUDIO L﹠amp; R, delivering to power amplifier again amplifies and to export to loudspeaker (2) photosignal after big is converted to initial data PS stream to sending out of reading in the DVD drive 3, and carry out the MPEG2 audio/video decoding, and then to decoded coding video data, video output signals such as output CVBS/YUV/RGB; To decoded voice data DAC, output AUDIO L﹠amp; The inner SERVO of R (3) watches multiple control system, mainly is that control DVD drive 4 reads optical disc data.(4) PS stream that will recorded program is exported to hard-disc storage, and then reads broadcast.
