Signal conversion module is connected with described central processing module, and the digital signal or the analog signal conversion that are used for described central processing module output are the high-definition multimedia signal.

The high-definition multimedia signaling interface; being called for short HDMI (High Definition Multimedia Interface) is a kind of digitized video/audio interface technology; it is the tailored version digital interface that is fit to image transmission; it can transmit audio frequency and video-audio signal simultaneously, need not simultaneously to transmit advance capable D/A or mould/number conversion at signal.The utility model can all convert video, the audio signal of multiple format to HDMI signal output, and is very easy to use, especially is suitable for the place that the floating population such as hotel lives.

Preferably, described signal input module comprises high-definition multimedia signal input module, Video Graphics Array signal input module (Video Graphics Array full name: Video Graphics Array, be called for short VGA), one or more in the composite terminal signal input module (the composite terminal full name: Composite video connector claims not only AV terminal), independent video signal input module (independent video signal terminal but also claim the S-terminal).

Preferably, described high-definition multimedia signal input module accesses described central processing module by the high-definition multimedia signal expansion circuit.

Preferably, be connected with charging module on the described voltage transformation module.

Preferably, described charging module comprises the USB charging module.

Preferably, the voltage of described USB charging module is 5V.

Circuit of the present utility model can be realized the function of multi-thread input one line output, and soon various video, audio signal all can be exchanged into the output of HDMI signal, and the input pattern of each signal can be auto transformation mode; Also can connect charging module at voltage transformation module, with the function of the portable charger of pegging graft simultaneously.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is the module connection diagram of the utility model multimedia Connection Block circuit structure preferred embodiment.

Embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

Multimedia Connection Block circuit structure of the present utility model comprises: central processing module, voltage transformation module, signal input module and signal conversion module, and wherein central processing module is used for various input signals are converted to same digital signal or analog signal output; Voltage transformation module is connected with described central processing module, is used for civil power is converted to the operating voltage of described central processing module; Signal input module is connected with described central processing module, is used for one or more videos of input, audio signal; Signal conversion module is connected with described central processing module, and the digital signal or the analog signal conversion that are used for described central processing module output are the high-definition multimedia signal.

As shown in Figure 1, in this preferred embodiment, central cpu signal processing module among the figure is described central processing module, and what described signal input module can be in high-definition multimedia signal input module, Video Graphics Array signal input module, composite terminal signal input module, the independent video signal input module is one or more.Left side in the drawings is the HDMI signal input module, i.e. the high-definition multimedia signal input module; The top of central cpu signal processing module also is connected with VGA and binaural signal input module, i.e. Video Graphics Array input module; The top of central cpu signal processing module also is connected with AV and S terminal signals input module, i.e. composite terminal signal input module and independent video signal input module.Certainly the utility model also can arrange one or two different signal input module, also can connect according to real needs the input signal of more other pattern, and be not limited only to illustrated several input mode.
