Description
Technical field
The utility model relates to mobile DVD, particularly a kind of mobile DVD encoding and decoding plate.
Background technology
Mobile DVD be a kind of will be by data of optical disk be carried out encoding and decoding, the multimedia instrument of playing, it has advantages such as easy to carry, powerful.The present encoding and decoding plate that mobile DVD adopted only can read the CD in compression modes such as MPEG-1, MPEG-2, is difficult to the encoding and decoding of realization to high-resolution broadcast dish, therefore can not play the CD of some high-resolutions.
For this reason, the someone has proposed a kind of high definition video disc and has made and play-back technology AVS HD (abbreviation of ADVANCEDDISC), and this technology can provide full HD digital picture of 1080P and 5.1 sound channels around digital stereo, realizes the result of broadcast of high definition digital cinema.But this technology has cost height, circuit to be constituted complicated, signal and moves towards problem such as loaded down with trivial details, so its popularization brings great difficulty.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide the mobile DVD encoding and decoding plate that a kind of technical pattern is simple, realization is convenient, with low cost.
For achieving the above object, the utility model is mainly by the following technical solutions:
A kind of mobile DVD encoding and decoding plate, include detuner, DVB processor, analogue signal processor, DVB selector switch, video switcher, audio process, audio switch, Video Decoder and central processing unit, described detuner is connected with the DVB processor, the output of DVB processor is divided into three parts, and first is connected with central processing unit by video switcher and Video Decoder; Second portion is connected with central processing unit by DVB selector switch, audio switch; Third part is connected with central processing unit by analogue signal processor, audio process.
Also be connected with tuner on the wherein said detuner, by sound, the vision signal of this tuner input are carried out demodulation.
Also be connected with storer and driver on the wherein said central processing unit.
The utility model is handled by sound, the video data that reads being carried out encoding and decoding, and result is stored in the storer by central authorities' processing, and utilizes disk drive to play.Compared with prior art, the utility model has improved the machine system integrated level of mobile DVD player, and exportable high-quality video data the utlity model has and makes advantages such as simple, with low cost, easy to operate.
Description of drawings
Fig. 1 is the utility model structured flowchart.
Identifier declaration among the figure: digital tuner 101, detuner 102, DVB processor 103, analogue signal processor 104, DVB selector switch 105, video switcher 106, audio process 107, audio switch 108, Video Decoder 109, central processing unit 110, storer 111, driver 112.
Embodiment
For setting forth thought of the present utility model and purpose, the utility model is described further below in conjunction with the drawings and specific embodiments.
See also shown in Figure 1ly, Fig. 1 is the utility model structured flowchart.The utility model provides a kind of mobile DVD encoding and decoding plate, include digital tuner 101, detuner 102, DVB processor 103, analogue signal processor 104, DVB selector switch 105, video switcher 106, audio process 107, audio switch 108, Video Decoder 109 and central processing unit 110, described detuner 102 is connected with digital tuner 101, carry out demodulation by DVB-T signal to this tuner input, and demodulation result outputed in the DVB processor 103, be divided into the output of three parts after 103 pairs of input signals of DVB processor are handled, first is connected with central processing unit 110 by video switcher 106 and Video Decoder 109; Second portion is connected with central processing unit 110 by DVB selector switch 105, audio switch 108; Third part is connected with central processing unit 110 by analogue signal processor 104, audio process 107.
In addition, central processing unit is handled the back to the above-mentioned audio frequency, the vision signal that receive and is generated high-definition video signal and stereo audio signal, and is kept in the storer 111, afterwards when needs are play, call above-mentioned signal by driver 112, play by loudspeaker or display device.
The utility model principle of work is: at first sound, vision signal are input in the digital tuner 101, be demodulated to intermediate frequency through detuner 102, output to DVB processor 103, and through behind the DVB selector switch 105, be broken down into audio stream and video flowing, output to video switcher 106 and audio switch 108 respectively, and the vision signal of video switcher 106 outputs is through the processing of Video Decoder 109, these audio frequency, vision signal are input to central processing unit 110 respectively and handle, and export corresponding signal by the external tapping of central processing unit 110.
More than be that a kind of mobile DVD encoding and decoding plate provided by the utility model is described in detail, used specific case herein structural principle of the present utility model and embodiment are set forth, above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
