Abstract
The invention discloses a DVD-RW that could realize radio video frequency signal wireless transferring. It includes inner core electric circuit and UWB module. The UWB module is made up of receiver, base band processor, and medium access controller. Receiver connects to antenna, and the system bus of DVD-RW inner core electric circuit connects to the medium access controller in UWB module. The invention uses UWB method to take wireless transmitting for audio video frequency signal. It could realize single DVD play on plural display devices.
Description
Technical field
The present invention relates to a kind of DVD product, in particular, relate to a kind of DVD burner that can realize the audio-video signal wireless transmission.
Background technology
Adopt cable to be connected between existing DVD burner and the multi-media receiver.During use, the corresponding terminal of DVD burner and receiver need be connected, the ability operate as normal is used very inconvenient.Simultaneously, the repeatedly plug of terminal is damaged easily, has reduced the reliability of transmission signals.And the separate unit DVD burner is play and can only be received by the separate unit display device, can not expand peripheral hardware.
Summary of the invention
The present invention is in order to overcome weak point of the prior art, to provide a kind of wireless transmission that can carry out audio-video signal, DVD burner easy to use.
The present invention is achieved through the following technical solutions:
A kind of DVD burner that can realize the audio-video signal wireless transmission, comprise DVD burner internal machine core electronic circuit, it is characterized in that, also comprise the UWB module, described UWB module is connected to form successively by transceiver, baseband processor and medium access controller, described transceiver is connected with antenna, and described DVD burner internal machine core electronics systems bus is connected with medium access controller in the UWB module.
The present invention has following technique effect:
DVD burner of the present invention utilizes the mode of UWB (the super wideband of Ultra WindBand) to carry out the wireless transmission of audio-video signal, can avoid loaded down with trivial details wiring, and is easy to use.Broken through traditional DVD player and multi-media receiver and used cable to be connected the inconvenience that is caused, more can with peripheral hardware expansion such as PC, be not subjected to the restriction of position within the specific limits, can realize that single DVD plays a plurality of display devices receptions.
Description of drawings
Fig. 1 can realize the internal circuit synoptic diagram of the DVD burner of audio-video signal wireless transmission for the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments to the detailed description of the invention.
Fig. 1 can realize the internal circuit synoptic diagram of the DVD burner of audio-video signal wireless transmission for the present invention, comprise DVD burner internal machine core electronic circuit and UWB module, described UWB module is connected to form successively by transceiver, baseband processor and medium access controller, described transceiver is connected with antenna, and described DVD burner internal machine core electronics systems bus is connected with medium access controller in the UWB module.
In the UWB module, transceiver and baseband processor have been formed minimum one deck of UWB together, become the Physical layer of UWB, are responsible for radiofrequency signal transmitting-receiving and base band signal process; Medium access controller (MAC) is as media access control layer, be responsible for being responsible for from basic reel number, demodulating effective information from base band, or effective information modulated into baseband signal, and cooperative system central processing unit and system provide hardware-software interface and user to use.On media access control layer with the operating system binding portion, system design can make full use of the characteristics of media access control layer super frame " Super Frame Structure ", arrange various communications protocols, as Wireless USB, wireless 1394, bluetooth 3.0, realize digital home's life pattern, UWB provides a shared wireless channel and technology platform.
DVD burner of the present invention is the module that increases a UWB in original DVD burner.DVD burner is picked up optical disc information by laser head, carries out DSP at digital signal processor afterwards and handles, and video signal compression, is sent to UWB module by system bus by the medium encoding and decoding.In the UWB module, modulate by medium access controller (MAC) earlier, effective information in the signal is modulated into baseband signal, by baseband processor and transceiver audio-video frequency media stream is sent to the UWB receiver module of display device again by the UWB wireless channel.Display device restores video image again by media decodes again.Simultaneously, this DVD burner can receive miscellaneous equipment and send to audio-video frequency media stream in the UWB wireless channel.Transceiver in the UWB module and baseband processor receive audio-video frequency media stream, carry out demodulation by medium access controller (MAC) again, demodulate effective information from baseband signal, send to media codec by system bus.After the media codec processing, can information burning be arrived CD by laser head on the one hand; Can will export by DVD such as A/V, S-VIDEO, YPbPr, HDMI, D-Terminal and SCART terminal commonly used after the information processing on the other hand.
The above only is preferred embodiment of the present invention, is not structure of the present invention is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
