When setup menu, VFD can only show the several characters of simple menu (menu), can not show menu under the menu have those projects, now in the browsing menu which and changed which setting.When at recording TV program, VFD can only show and recording that channel, can not show how long recorded, can not show more whether present institute recorded program finishes, this brings very big inconvenience just for user's controlling DVD video tape recorder, cause recording TV program redundant phenomenon to occur easily, waste CD resource.
The utility model content
The purpose of this utility model is, a kind of CD ROM drive device is provided, and solves existing CD-ROM device operation inconvenience, causes recording TV program redundant phenomenon to occur easily, waste CD resource.
The technical solution of the utility model is, a kind of CD ROM drive device is provided, comprise this machine of the CD-ROM device module, the LCD display module that are used to separate video data stored on the code rom, described DVD decoding and coding device, DVD driver, the input signal processing module that the machine module comprises the host computer control chip and is connected with the host computer control chip respectively, described input signal processing module is also connected to the Voice ﹠ Video input source, and described DVD decoding and coding device is connected to television set and LCD display module by video signal cable.
In the above-mentioned CD ROM drive device, described input signal processing module comprises NTSC/PAL decoder, video encoder, audio frequency analog to digital converter, audio coder, wherein the NTSC/PAL decoder is connected to the vision signal input source and is connected to the host computer control chip via video encoder, and described audio frequency analog to digital converter is connected to the audio frequency input source and is connected to the host computer control chip via audio coder and video encoder.
In the above-mentioned CD ROM drive device, the video signal cable of described connection DVD decoding and coding device is divided into three road rgb signal lines via the video output module and is connected to the LCD display module.
In the above-mentioned CD ROM drive device, described machine module also is connected with the LCD display module with the data line synchronous signal line synchronously by data fields.
In the above-mentioned CD ROM drive device, described machine module also is connected with the LCD display module by the data clock pulse signal-line.
In the above-mentioned CD ROM drive device, described machine module also is connected with the LCD display module by the data enable control signal wire.
In the above-mentioned CD ROM drive device, described machine module also comprises the DV codec that is connected with the host computer control chip, and described DV codec is connected to external equipment via 1394 links and 1394 physical ports.
CD ROM drive device of the present utility model, replace the display screen of VFD with LCD as CD-ROM device, can be under the situation that does not have display terminal (television set), LCD is every function of display menu clearly also, thereby can the operating state that must understand CD-ROM device very directly perceived makes things convenient for the operation of CD-ROM device.
Description of drawings
Fig. 1 is the system configuration schematic diagram of existing DVD device.
Fig. 2 is the system configuration schematic diagram of CD ROM drive device of the present utility model.
Embodiment
As shown in Figure 2, be the system configuration schematic diagram of CD ROM drive device of the present utility model (is example with the DVD device).Get the DVD device in the present embodiment and comprise DVD device body module 200, operation keyboard 217 and LCD display module 219.
Be sent to master control chip 210 after the processing of vision signal (for example from TV signal) via NTSC/PAL decoder 202 and Video Decoder 203 of input, also import the input/output end port of host computer control chip 210 after the audio signal of input (for example from TV signal) is handled via audio frequency analog to digital converter 205, audio coder 206, video encoder 203.The data of importing host computer control chip 210 through video encoder 203 and audio coder 206 coding backs are the audio or video data of specific format, for example MPEG-2 Media Stream etc.Read-write DVD driver 111 can be with from the audio frequency of main frame control chip 110, the video data imprinting DVD laser disc.Read-write DVD driver 111 also can be common DVD playback equipment, but its DVD playing back laser disc only, and can not record the DVD laser disc.
