Description

DVD player with video record function

Technical field

The utility model relates to a kind of DVD player, particularly a kind of DVD player with video record function.

Background technology

At present, the hard disc recording technology is not a new notion, security product has been used this technology very early, along with the continuous development of hard disc recording technology and the progress at full speed of hard-disk capacity, hard disc recording has entered market widely, on a lot of products application is arranged all, particularly along with the appearance of Digital Television and becoming better and approaching perfection day by day of mpeg decode technology, this technology has vast market prospect especially, and video record also becomes more and more popular vocabulary.And concerning DVD player, it has broken the historical record of consumer electronics already to the infiltration of family, DVD player develops to multi-functional videocorder direction from single play-back technology, and follow-on DVD player will be as the home entertainment center in digitizing living room.If DVD player can have the function of video record simultaneously, will satisfy consumer's needs greatly, also improve the function of significant equipment in its networked family more.

The utility model content

The purpose of this utility model is to overcome above-mentioned weak point, provides a kind of circuit simple, reasonable in design, the DVD player with video record function of dependable performance.

The technical scheme that the utility model adopted is for achieving the above object: a kind of DVD player with video record function is characterized in that this circuit comprises DVD playing circuit, video record control and treatment chip, MPEG-2 coding decoder, internal memory, storer and hard disk; The television audio signals of input is handled by the MPEG-2 coding decoder by analog to digital converter, vision signal, through filter make an uproar, estimation inserts video record control and treatment chip; Described DVD player circuit links to each other with hard disk, and described video record control and treatment chip links to each other with the MPEG-2 coding decoder, and is connected in the master chip processor, at last again by A/V encoding and decoding conversion processing unit processes and output.

Specifically, behind the TV signal video and audio signal process demodulating and decoding with input, send the MPEG-2 scrambler to and encode; Digital signal behind the coding is stored in the middle of the video record, notes the content that will write down with certain form by the processing and the control of video record control and treatment chip; When the user need play then be by video record control and treatment chip receive outside read signal after, the location records of the content that read is got off, by the A/V code conversion, the mpeg stream signal is play on television terminal; Also has the function of DVD playing back signal immediately simultaneously.

The beneficial effects of the utility model are: compare with DVD player in the past, the maximum characteristics of this product are the functions that has broadcast of DVD signal and the imprinting of video record hard disk simultaneously.The user can see program on one side, Yi Bian carry out fast and accurately program being carried out jumbo real-time storage.And can pass through caching technology, and in progress program is suspended, can continue to play from time-out again after a period of time.The imprinting of video record hard disk has easily big, digitizing, the characteristics of searching fast, can be so that DVD CD limit imprinting TV programme be watched on the consumer limit, realized the function of time shift storage, can be so that the arbitrary TV of seeing of consumer will be subjected to consumers in general's favor.Its circuit is simple, and is reasonable in design, dependable performance, and can carry out large-scale production, to satisfy the demand in wide market.

Description of drawings

Fig. 1 is that the utility model circuit structure connects block diagram.

Embodiment

Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to embodiment, structure, feature that foundation the utility model provides:

As shown in Figure 1, a kind of DVD player with video record function comprises the original circuit of DVD player, video record control and treatment chip, and the MPEG-2 coding decoder, internal memory (DDR) IV, storer (FLASH) V and hard disk (HDD) are formed.By the DVD video interface, to want the television content of imprinting promptly to receive the vision signal II of TV, after at first carrying out demodulation, input to Video Decoder, the digital video signal that obtains the BT656/601 form after the decoding sends the MPEG-2 demoder to, sound signal I then directly by after mould/number conversion, becomes digital signal by analog-signal transitions, directly sends the MPEG-2 demoder to.This demoder is filtered the processing of making an uproar to the received signal, and estimation III and digitized signal are encoded with the form of MPEG-2 after handling.

The digital signal that to encode is sent among the HDD, by video record control and treatment chip controls, stores in the middle of the HDD with certain form certain sequence.When the user need read the information that is stored in the middle of the HDD, master chip will send steering order of video record control and treatment chip to, the target information that will read is read in corresponding position from HDD, and transmit corresponding information and give the master chip processor, after the master chip processor is received signal, control A/V demoder after decoding accordingly, finally plays back the mpeg stream signal on TV TV terminal.Simultaneously also can be according to user's self needs by the infrared IR signal controlling on the telepilot, and MPEG-2 scrambler DVD playing back signal.Video record control and treatment chip can adopt the commercially available prod of Silicon manufacturer; The master chip processor can adopt the commercially available prod of SAMSUNG manufacturer.

This player is a kind of DVD player that has the video record function simultaneously, and the utility model when having increased the receiving digital television program, can carry out the storage of program and the function of magnanimity buffer memory on the basis of DVD player original function.

Above-mentioned detailed description of the DVD player with video record function being carried out with reference to embodiment is illustrative rather than determinate, therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection domain of the present utility model.

Claims

1. the DVD player with video record function is characterized in that this circuit comprises DVD playing circuit, video record control and treatment chip, MPEG-2 coding decoder, internal memory, storer and hard disk; The television audio signals of input is handled by the MPEG-2 coding decoder by analog to digital converter, vision signal, through filter make an uproar, estimation inserts video record control and treatment chip; Described DVD player circuit links to each other with hard disk, and described video record control and treatment chip links to each other with the MPEG-2 coding decoder, and is connected in the master chip processor, at last again by A/V encoding and decoding conversion processing unit processes and output.
