The rewritable blue-ray digital laser videodisc player comprises an electronic mechanism circuit, a tuning circuit, an ADC/DAC conversion circuit and an input/output electronic circuit; wherein, the electronic mechanism circuit, which is arranged in a shell, comprises a servo control system, a CPU control system and a coding and encoding system; the built-in hard disk is arranged in the shell as well; the CPU control system and the coding and encoding system of the electronic mechanism circuit are respectively connected with the built-in hard disk through an IDE interface; the built-in hard disk is connected with the input/output electronic circuit through the coding and encoding system, the tuning circuit and the ADC/DAC conversion circuit; and the input/output electronic circuit is connected with a peripheral device through an output interface. The rewritable blue-ray digital laser videodisc player has the following advantages: the rewritable blue-ray digital laser videodisc player can ensure the highest-image-quality and highest-tone-quality playback, editing and storage; use is convenient; operation is simple; and the storage capacity can be expanded unlimitedly by utilizing the interface connecting the built-in hard disk with the peripheral device.

Description

Built-in hard disk blue light digital laser etch-recordable type video disc player

Technical field

The utility model relates to blue-ray DVD, relates in particular to a kind of built-in hard disk blue light digital laser etch-recordable type video disc player.

Background technology

Along with the blue-ray DVD player development of technologies, technology blue-ray DVD series of products has widely entered market in large quantities, because blue-ray DVD has the advantage that capacity is big, sharpness is high, blue-ray DVD is by the consumer acceptance.And along with the progress of science and technology, improving constantly of people's level of consumption and demand layer, the consumer is also more and more higher to the function application demand of blue-ray DVD product, and the blue-ray DVD that possesses imprinting and playing function is simultaneously becoming the main flow in market, more and more is subjected to consumer's favor.But blue-ray DVD player exists the limitation of function singleness, and in technology longitudinal development, the horizontal integration of technology also is the certainty of blue-ray DVD production development, and blue-ray DVD CD writer+built-in hard disk is exactly the product in DVD horizontal field development.

Summary of the invention

In order to solve the deficiency of existing play-back technology and memory technology, better improve the function of blue-ray DVD CD writer, the utility model provides a kind of diversification, compatibility built-in hard disk blue light digital laser etch-recordable type video disc player widely especially, this system schema with blue-ray DVD CD writer and built-in hard disk integral body, for TV programme or DVD are being burnt to beyond the CD, another kind of powerful storage medium is provided, and by built-in hard disk can to carry out good information mutual with PC, thereby reach reading and recording of high-quality video-audio signal.

From technical standpoint, the player of blue-ray DVD CD writer+built-in hard disk designs for the function of improving the blue-ray DVD CD writer just, it has not only comprised the advantage that blue-ray DVD itself is had, and it is big to have a capacity of recording, the specific while of compatible multiple audio frequency and video form provides maximum compatibility again, has increased the capacity upgrade of product and easy to use.

The technical scheme that the utility model is taked to achieve these goals is: a kind of built-in hard disk blue light digital laser etch-recordable type video disc player, comprise and being arranged in the casing and by servo-control system, system control cpu, the movement electronic circuit that coding/decoding system constitutes, tuned circuit and ADC/DAC change-over circuit, the input and output electronic circuit, it is characterized in that: also be provided with built-in hard disk in the described casing, the system control cpu of described movement electronic circuit is connected with described built-in hard disk by ide interface respectively with coding/decoding system, built-in hard disk passes through coding/decoding system again, tuned circuit is connected with described input and output electronic circuit with the ADC/DAC change-over circuit, and the input and output electronic circuit is connected with external unit by output interface.

The utlity model has following beneficial effect: guaranteed high image quality and tonequality broadcast/editor/storage.Easy to use, simple to operate.Because the interface that has used built-in hard disk to be connected with external unit can infinitely enlarge the capacity of storage.

Embodiment

As shown in Figure 1, after blue-ray DVD CD writer movement reads optical disc information, through servo/DSP/ coding and decoding process, under the control of CPU, 1. the A/V audio-video signal is directly exported to behind the input/output electronic circuit pack directly and to be exported the back by lead-out terminal and connect display device and play; 2. direct recording behind the audio-video signal decoding and coding is preserved to the enterprising edlin of built-in hard disk; 3. by input interface (USB/IEEE1394/MODEM/AV terminal etc.), the relevant audio, video data of external unit (disk cartridge/Digital Video/digital camera etc.) is saved in the enterprising edlin of hard disk preserves; 4. the various audio, video datas of hard-disc storage are directly exported by coding/decoding system with after exporting electronic circuit.

As shown in Figure 2, when CD is broadcast part action and is put, according to the operation of telepilot and control panel instruction is transferred to after CPU handles, under the control of CPU, compatible following CD: CD/VCD/SVCD/CVD/CD-R, RW/DVD/DVD-AUDIO/DVD-R, RW, DVD+R, RW/SACD will be play by output behind the coding/decoding from the information that CD picks up.Broadcast, the editor of forms such as support MPEG1/MPEG2/MPEG4/MP3/WMA/JPEG/DIVX.The audio/video information of DVD (VCD) player, video camera, STB, CATV digital camera can be transcribed the enterprising edlin management of hard disk.

As shown in Figure 3, not only the information that reads from CD can be recorded on the built-in hard disk, and store on the hard disk after the various audio/video informations of outside input can being handled by electronic circuit, can edit canned data on the hard disk simultaneously.The information that writes down on the hard disk also can be exported to lead-out terminal by the coding and decoding electronic circuit and export broadcast.
