Abstract
The utility model relates to a TV set, in particular to the TV programme's record and playback technology. The utility model provides a TV programme recording and replaying device of low cost, which is characterized in that: the multi-functional TV set comprises a TV signal receiving unit, a TV signal processing unit, a control unit, and also a digital signal processing unit and a digital signal storing unit. The digital signal processing unit is connected with the control unit and the TV signal processing unit; the digital signal storing unit is connected with the digital signal processing unit. The utility model has the advantages that: it can add the TV programme recording function and realize the playback function with few cost on the common TV set to achieve the integration of the sighting, recording and replaying of the TV programme.
Description
Technical field
The utility model relates to television set, particularly the record of TV programme and reproducing process.
Background technology
Along with the development of TV tech to the digitlization direction, and capacity, the extensive use of storage medium cheaply greatly, traditional video tape recorder, withdraw from the arena of history of video-with-audio recording and playback gradually, the substitute is the DVR that adopts the digital signal memory technology and DVD burner etc.Particularly be accompanied by the appearance of various advanced persons' compression (coding) standard, as MPEG2, MPEG4, H264 etc., the packing density of audio-video signal is more and more higher, and reproduction quality is become better and better.
As the application that average family writes down and returns a TV show, adopt traditional video tape recorder obviously outdated, and adopt DVR or DVD burner, or cost is too high, or volume is too big.
The utility model content
Technical problem to be solved in the utility model just provides a kind of telerecording cheaply and replay device.
The technical scheme that the utility model solve the technical problem employing is that multi-function TV set comprises the TV signal receiving element, processing television signals unit, control unit; Also comprise digital signal processing unit and digital signal memory cell; Described digital signal processing unit is connected with control unit and processing television signals unit, described digital signal memory cell with state digital signal processing unit and be connected.
The beneficial effects of the utility model are, just can install the real-time recording TV programme additional with less cost and realize the function of playback on general television set, realize the watching of TV, record, playback is in one.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model;
Fig. 2 is the structured flowchart of embodiment.
Embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
The utility model is built in television set with PVR (program recording and playback) function, only uses the cost about 300 yuan, just makes a general television set become the collection TV program watching, record, and playback is the unit mahine of one.
The technical solution of the utility model is that multi-function TV set comprises the TV signal receiving element, processing television signals unit, control unit; Also comprise digital signal processing unit and digital signal memory cell; Described digital signal processing unit is connected with control unit and processing television signals unit, and described digital signal memory cell is connected with digital signal processing unit;
Concrete is described digital signal processing unit MPEG compatible 2, MPEG4, H264 form;
Further be that described digital signal memory cell is made of NAND FLASH and/or storage card;
More particularly, described digital signal processing unit is by A/D converter, D/A converter, and DSP and plug-in memory storage SDRAM thereof and NOR FLASH constitute; Described A/D converter is connected with DSP and processing television signals unit, and the analog signal conversion that the processing television signals unit is exported becomes digital signal input DSP; Described DSP is used for the coding/decoding of digital signal to be handled and system's control; Described D/A converter is connected with DSP and processing television signals unit, DSP is exported digital signal convert analog signal input TV signal processing unit to.
Referring to Fig. 1, multi-function TV set of the present utility model comprises the TV signal receiving element, processing television signals unit, control unit, digital signal processing unit and digital signal memory cell.TV signal is sent to the processing television signals unit through the tuning reception of TV signal receiving element.After the processing television signals unit is handled TV signal, export a part of signal, finish common television function to display system and audio system; Another part signal supplied with digital signal processing unit is encoded through digital signal processing unit, and last supplied with digital signal cell stores is finished the digitized record of TV programme.The playback of TV programme is, digital signal processing unit reads the digital signal of digital signal memory cell, and after decoding, the input TV signal processing unit is finished the playback of TV programme.Said process is all at control unit, and finishes under the common control of the inner DSP of digital signal processing unit, and control unit is communicated by letter with other unit, passes through I
2The bus of C bus or other types is carried out.
In the technical solutions of the utility model, the concrete structure of digital signal processing unit is according to the different and difference to some extent of the signal processing model of processing television signals unit.For processing television signals unit with digital signal processing capability, as popular instantly digital television etc., owing to itself can export digital signal, the digital signal processing unit here only need be finished coding, the decoding of digital signal, comprises that the coding of forms such as MPEG2, MPEG4, H264, decoding get final product.In the utility model, the digital signal memory cell can be NAND FLASH, storage mediums such as storage card.Its capacity is configuration capacity as required, can adopt the combination of various storage mediums, also can use NAND FLASH or storage card separately.
Embodiment
Fig. 2 shows the structure of this routine digital signal processing unit.This routine processing television signals unit is an analogy signal processing unit, and this routine digital signal processing unit comprises A/D converter, D/A converter, DSP and SDRAM and NOR FLASH.A/D converter is connected with the processing television signals unit among the figure, and the analog audio-video signal of its output is carried out mould/number conversion respectively, then digital audio-video signal is sent to DSP and encodes, and the digital signal through coding is stored among the NAND FLASH.During programme replay, DSP reads the digital signal among the NANDFLASH, is sent to D/A converter and carries out D/A switch after decoding, exports the analog audio-video signal at last to the processing television signals unit.CPU and DSP adopt the bidirectional linked list bus to communicate among the figure.
