Abstract

The utility model relates to the DVD field, in particular to a DVD capable of reading external data, wherein, a set of power supply modules dedicated for supporting the operation of external storage units is arranged on the power supply unit in the module of a DVD body, a control module in the electronic circuit of the body module is connected with power supply drive circuits for the external storage units, and the input-output interface circuit in the electronic circuit is connected with the drive circuits for the external storage units respectively. Therefore, the DVD ensures the normal operation of various external storage units, reads the internal data from the external storage units, and displays graphics, music and movie information for a platform. Moreover, the DVD equipment has wider applications, and solves the problem that the operation of a mobile hard disk can only realized through a computer.

Description

A kind of DVD that can read external data
Technical field
The utility model relates to a kind of DVD field, specifically refers to a kind of DVD that can read external data.
Background technology
Along with the develop rapidly of electronic technology, the variation of storage medium, portable degree is more and more higher, and the memory storage of various novel record data is used and is given birth to.But the data of storing in the existing storage medium need just can be finished reading of external data by computer or specific player, and for example existing DVD can only read the data of putting down in writing on the laser disc in the CD-ROM drive.As shown in Figure 1, be the system architecture synoptic diagram of existing DVD video tape recorder device, it comprises DVD video tape recorder device body module 100, display control chip 115, operation board 116 and VFD display screen 117.Deliver to main control chip 110 after the processing of vision signal via NTSC/PAL demoder 102 and Video Decoder 103 of input, the sound signal of input is also imported host computer control chip 110 via audio frequency analog to digital converter 105, audio coder 106, video encoder 103 after handling; And DVD driver 111 can read the data on the DVD laser disc and outputs to display by DVD demoder 104.In addition, host computer control chip 110 also is connected with display control chip, by the duty of VFD display screen 117 show ontology modules 100, and passes through the duty that operation board 116 is controlled the DVD devices.Existing DVD is by driving laser disc reading of data, and the memory space of laser disc is smaller, is generally 4.7G, and a CD can only be stored the capacity of a high-resolution film.The storage data such as data that read the storage of other external datas such as portable hard drive comparatively speaking are inconvenient, and this has limited the development of DVD technology undoubtedly.
Summary of the invention
The utility model purpose is to provide a kind of DVD that can read external data, can read multimedia messagess such as picture, music, film from external memory unit to reach DVD, and storage unit such as minimizing portable hard drive can only be in the circumscribed purpose of computer applications.
A kind of DVD that can read external data of the utility model, comprise DVD body module, display control chip, operation board and VFD display screen, the power supply unit of described DVD body module inside is provided with one group of power module of specializing in the external memory unit running, and the control module in the electronic circuit of body module is connected with the power driving circuit of external memory unit, and the input/output interface circuit in the electronic circuit is connected with the power driving circuit of described external memory unit respectively.
Described external memory unit comprises portable hard drive, eight-in-one card reader.
Described DVD body module is provided with USB interface.
Being provided with in the described control module and distinguishing physical disks is the discriminating module of CD-ROM drive or hard disk.
A kind of DVD that can read external data of the present utility model, on the power supply unit of DVD body module inside, be provided with one group of power module of specializing in the external memory unit running, and the control module in the electronic circuit of body module is connected with the power driving circuit of external memory unit, and the input/output interface circuit in the electronic circuit is connected with described external memory unit driving circuit respectively.Thereby guarantee that various external memory units can operate as normal turn round, the internal data that makes DVD also can read external memory unit is platform playing pictures, music, film information by DVD, expanded the application of DVD, also having reduced portable hard drive can only be in the limitation of computer broadcast.
Description of drawings
Fig. 1 is existing dvd system structural representation;
Fig. 2 is a principle schematic of the present utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Be to be understood that concrete embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 2 is a kind of inside schematic diagram that can read external data DVD of the utility model, comprises DVD body module 100, display control chip, operation board and VFD display screen; Laser pickup head in the present embodiment is connected with control module 170 with the SDRAM synchronous DRAM respectively, and described control module 170 is connected with body module 100.Described body module 100 is connected with coding/decoding module with SDRAM respectively, described coding/decoding module is connected with input/output interface circuit 150, in order to read external data, the power supply unit of described DVD body module 100 inside is provided with one group of power module 180 of specializing in the external memory unit running, and the control module in the electronic circuit of body module 100 170 is connected with the power driving circuit 160 of external memory unit, and the input/output interface circuit 150 in the electronic circuit is connected with the power driving circuit 160 of described external memory unit respectively.
Described external memory unit comprises portable hard drive, eight-in-one card reader.When with USB or Digital Video, digital camera RAM (random access memory) card and after DVD is connected, under the control of body module 100 innernal CPUs and control module 170, information is temporary by SDRAM, coding/decoding module carries out decoding processing, the tabulation of data message in USB or the RAM (random access memory) card is shown on TV, by telepilot or operation board tabulation is chosen, get content earlier and export to input/output interface circuit 150 after by decoding processing, directly connect TV and play, can play information datas such as browsing photo the picture sequence in the RAM (random access memory) card by lead-out terminal output back.In addition, being provided with in the described control module 170 and distinguishing physical disks is the discriminating module of CD-ROM drive or hard disk, this discriminating module can be distinguished the raw partition of hard disk, control module 170 can find by the data content of body module 100 innernal CPUs with each subregion, can only be in the limitation of computer broadcast thereby reduced portable hard drive.Described control module 170 is connected with the laser pickup head, can carry out servo and the control of CD subregion to external memory unit.
Portable hard drive is connected with the USB interface of DVD, the power supply of power module 180 drives 160 pairs of portable hard drives of driving circuit, the data of portable hard drive are shown on TV by input/output interface circuit 150, coding/decoding module, and can also pass through the CD writer imprinting.So just, the internal data that makes DVD also can read external memory unit is platform playing pictures, music, film information by DVD, has also expanded the application of DVD, and also having reduced portable hard drive can only be in the limitation of computer broadcast.
