In addition, continuous development along with the personal consumption series products, consumers in general are in the face of a lot of digital equipments at present, such as MP3, DVD, DV, PDA, digital camera etc., therefore the consumer also needs a general multifunctional access jaws equipment, as long as receiving, can finish on this interfacing equipment and being connected of computer all these peripheral hardwares, the data of various digital equipments are passed through this interfacing equipment, be transported on the various digital audio-video equipment in the family, as televisor, projector, other giant-screen digital distance scopes, home theater and high fidelity sound system or the like, can enjoy a trip to the Internet webpage by large screen television, appreciate various forms at the spider lines sheet, browse the digital format DV image in the computer, watch the picture of the various forms in the computer; Listen to beautiful music by high-fidelity music center.
Summary of the invention
The technical issues that need to address of the present invention are, comparatively single at present existing interfacing equipment function, different application needs adopts different interfacing equipments, and interfacing equipment also exists system flexibility poor, defectives such as extended capability difference, make that the connection between the equipment is very complicated, in disorder, and connection error takes place easily, in order to overcome these problems, the present invention has redesigned a kind of compact conformation, easy to operate digital integral multimedia computer general purpose interface makes the compatible and perfect fusion of household electrical appliances audio-visual products of the powerful medium of computer by this interfacing equipment.The purpose of this utility model is to provide a kind of digital integral multimedia computer general purpose interface, this purpose is achieved through the following technical solutions, a kind of digital integral multimedia computer general purpose interface, the circuit board that comprises equipment outer cage and casing inside, it is characterized in that, include the CPU CPU (central processing unit) on this circuit board, and coupled infrared signal receiving demodulation unit, nonvolatile memory, the multi-media signal combined interface that links to each other with control bus, it includes four groups of input signal interfaces and corresponding output interface again; The casing front panel is provided with four groups of input signals, options button and signal condition indication.
Described four groups of input signals, they are respectively R F radio television signal, audio frequency basic code flow, Doby audio code stream and multi-medium data frequently; Four kinds of signal correspondences this digital integral multimedia computer general purpose interface and can be worked under four kinds of patterns, and they are respectively,
1. television mode
Under this pattern, need not to open host computer or start any software, only need to connect television antenna and switch to television mode with telepilot, can watch excellent TV programme by computer monitor, cooperate highlighted flat-screen CRT monitor, the picture exquisiteness is exquisite, color is beautiful in riotous profusion, obtains the display effect more even better than televisor.
2. video disc play mode
Under this pattern, the operating system that can not enter computer is play the video disc of the forms such as VCD/DVD in the CD drive, and supports F.F., rewind down, time-out, and functions such as the automatic shutdown in back finish playing.
3. music playing mode
Under this pattern, the operating system that can not enter computer is play the music file of forms such as CD, MP3 in the CD drive, AC-3, and supports F.F., rewind down, time-out, search, and back function such as shutdown automatically finishes playing.
4. multi-medium data tupe
Under this pattern, the operating system that can not enter computer is handled various multi-medium datas, browses photo such as connecting digital camera, connects PDA and handles personal data etc.
Above-mentioned four kinds of mode of operations all can be undertaken by telepilot, make things convenient for the user to operate in certain distance, have also satisfied the use habit of domestic consumer to household electrical appliance.
