Abstract

The utility model discloses an integrated digital laser recordable video disk and hard disk device, comprising a body case, an electronic circuit of the core of a digital laser recordable video disk device, and an input and output electronic circuit. The CPU and the encoding and decoding system in the electronic circuit of the core of the digital laser recordable video disk device is connected with an internal hard disc and an external hard disc through IDE interfaces; the internal and the external hard discs are connected with corresponding external devices through corresponding interfaces, and the encoding and decoding system in the electronic circuit of the core of the digital laser recordable video disk device is connected with the input and output electronic circuit through a tuning circuit; the electronic circuit of the core of the digital laser recordable video disk device, the input and output electronic circuit, and the internal and the external hard discs are arranged in the same body case. By using the interfaces used to connect the internal and the external hard discs and the external devices, the storage capacity can be enlarged infinitely. Because the storage capacity is large and the recording capacity is large, various audio and video formats are compatible and the capacity of the device is increased, making the utility model having the advantage of easy use.

Description

A kind of digital laser etch-recordable type video disc player and hard disk all-in-one

Technical field

The utility model relates to a kind of DVD product and expansion field thereof, relates in particular to a kind of product that digital laser etch-recordable type video disc player and built-in/external hard disk are made up.

Background technology

Along with the DVD player development of technologies, technology DVD series of products has widely entered market in large quantities, because DVD has the advantage that capacity is big, sharpness is high, 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 DVD product, and the 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 because the DVD player function singleness, memory capacity is little, and it is little that digital laser etch-recordable type video disc player (DVD RECORDER) is recorded capacity, can not compatible multiple audio frequency and video form, and product capacity upgrading difficulty is used inconvenient.

The utility model content

The utility model mainly solves the deficiency of existing play-back technology and memory technology, and a kind of diversification is provided, and extensively compatible, it is big to record capacity, digital laser etch-recordable type video disc player easy to use and hard disk all-in-one.

The technical scheme that its technical matters that solves the utility model adopts is:

A kind of digital laser etch-recordable type video disc player and hard disk all-in-one, comprise casing, digital laser etch-recordable type video disc player movement electronic circuit and input and output electronic circuit, it is characterized in that the CPU in the described digital laser etch-recordable type video disc player movement electronic circuit is connected with external hard disk with built-in hard disk by ide interface with coding/decoding system; Described built-inly be connected with counterpart external device by the corresponding interface with external hard disk, the coding/decoding system in the described digital laser etch-recordable type video disc player movement electronic circuit is connected with the input/output electronic circuit by tuned circuit; Described digital laser etch-recordable type video disc player movement electronic circuit and input/output electronic circuit and built-in and external hard disk are in same casing.

The utlity model has following beneficial effect:

Owing to used the built-in interface that is connected with external unit with external hard disk, so can infinitely enlarge the capacity of storage.Because memory capacity is big, it is big that DVD RECORDER records capacity, and the compatible multiple audio frequency and video form of energy has increased the product capacity upgrading, and is easy to use, simple to operate.Have the video recording and the function of video reproduction, the while has guaranteed high image quality and tonequality broadcast/editor/storage on the basis of existing technology.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in detail.

The utility model digital laser etch-recordable type video disc player and hard disk all-in-one cut-away view are as shown in Figure 1, comprise casing, digital laser etch-recordable type video disc player movement electronic circuit and input and output electronic circuit, CPU in the digital laser etch-recordable type video disc player movement electronic circuit is connected with external hard disk with built-in hard disk by IDE (Integrated Drive Electronics) interface with coding/decoding system, built-in/external hard disk is connected with external unit such as disk cartridge/digital camera etc. as USB (2.0)/IEEE1394/ storage card/MODEM interfaces such as (modem) by the corresponding interface.Coding/decoding system in the digital laser etch-recordable type video disc player movement electronic circuit is connected with the input/output electronic circuit by tuned circuit, and tuned circuit is finished the ADC/DAC conversion.Digital laser etch-recordable type video disc player movement electronic circuit and input/output electronic circuit and built-in/external hard disk are in same casing.

After DVD RECORDER 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/external hard disk; 3. by input interface,, external unit such as disk cartridge/Digital Video/relevant audio, video datas such as digital camera are saved in the enterprising edlin of hard disk preserve as the USB/IEEE1394/MODEM/AV terminal etc.; 4. the various audio, video datas of hard-disc storage are directly exported by coding and decoding 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, will plays by output behind the coding/decoding from the information that CD picks up, compatible following CD: CD/VCD/SVCD/CVD/CD-R, RW/DVD/DVD-AUDIO/DVD-R, RW, DVD+R, RW/SACD. support the broadcast of forms such as MPEG1/MPEG2/MPEG4/MP3/WMA/JPEG/DIVX, editor.Can be with DVD (VCD) player, video camera, STB, the audio/video information of CATV digital camera are 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 built-in/external 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.

Although relate to a kind of digital laser etch-recordable type video disc player and the hard disk all-in-one has carried out special description to disclosed with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
