Description
Technical field
The present invention is a kind of multimedia video and audio device, refers to a kind of main frame that has especially, but but the AV device of independent play-out video/audio function.
Background technology
At present because the maturation of computing machine science and technology prosperity and digitized video treatment technology makes the function of computing machine execution no longer only be confined to simple data processing or storage.In addition, still can cooperate peripheral circuit or Unit Installation, as shown in Figure 7, make main frame 70 read video disc data and transmission display device 71 and loudspeaker 72 and play, make computer function rise to the stratum of media product.
Though multimedia computer has the function of multimedia at present, use-pattern still needs start earlier could control the video disc reading device and reads audiovisual materials, and transmission display device and loudspeaker are play again.With regard to general user's use habit, when long-time ornamental film, other hardware of computing machine or periphery will can not be used, and the built-in many function adapters of main frame, even be circumscribed with different peripheral products, when computer booting is only made audio-video playing function, though these hardware and peripheral unit are not used and are under idle state, but owing to still be in the connection power supply status, also can electric consumption.Therefore, computer function more tend to become strong big now, though can satisfy the user demand of user's each side, relatively cause the complexity that expends and increase service routine of power supply.
Though there is notebook computer partly to have the happy function of audible sound of need not starting shooting at present, notebook computer is under open state not, and display also can't use, therefore, even if audible sound is happy, but the user still can't carry out the action of selected songs, so still inconvenience to some extent.
In sum, for satisfying the demand of user's each side, as if the computing machine strong multimedia can replace audio-visual devices such as TV in the family, sound equipment, but, when the user uses these to set up function through computing machine, but use audio-visual audio-visual apparatus poor in the convenience of using more than simple, therefore, though computing machine integrates powers such as editor, storage, audio-visual broadcast, burning, online, and the user seldom can use all functions simultaneously, so, will cause the waste of computer resource and electric power.
Summary of the invention
For this reason, fundamental purpose of the present invention provides a kind of motherboard at main frame not under the open state, but the device of independent play-out audio-visual multimedia data still, and image and voice signal can be exported to respectively on display and the loudspeaker, so that the user to be provided the most direct audio-visual Play Control function.
Desiring to reach the employed major technique means of above-mentioned purpose is to make this multimedia video and audio device mainly be made up of a motherboard, a video process unit and a multimedia videodisc reading device, wherein this motherboard and video process unit are connected with independent current source separately, and connect multimedia videodisc read-write equipment jointly, so, this video process unit can directly be controlled multimedia videodisc read-write equipment under the state that motherboard is not opened, carry out audio-visual broadcast.
The present invention's time purpose is to make this multimedia video and audio device further include receive functions such as frequency modulation broadcasting and processing cable TV signal.That is, above-mentioned video process unit includes:
One frequency modulation processing unit, the sound output of its output terminal and this video process unit is exported by this voice output terminal after receiving the wireless frequency modulation voice signal and being converted to voice signal; And
One processing television signals unit, it has a concentric cable input end, for the cable TV signal input, it is treated to digital signal output again.
Still a further object of the present invention is to make this multimedia computer have the function that makes things convenient for of remote control.The main control chip of above-mentioned video process unit further is provided with an infrared receiver, to cooperate the signal that receives telepilot emission, and the action that makes things convenient for this video process unit of remote control to play videodisc.
