Abstract
The utility model discloses an external installing plug-and-play of USB in AV devices, which comprises a USB interface, a USB driving module, an audio decoding module, a checking module and a control module, wherein the output end of the USB interface is connected with the USB driving module, and the USB driving module is also respectively connected with the audio decoding module, the checking module and a main control circuit of the AV device. An output end of the checking circuit, an output end of the audio decoding module are connected with the control module and the control module is respectively connected with an audio input end and an audio frequency processing circuit of the AV device. The utility model can accomplish plug and play via discovering, checking, identifying, controlling and automatically playing and the compatibility of the AV device can be increased. With the utility model, existing AV devices can be extended on the basis of a program source and can download various audio and video files to play via a USB, a mobile hard disk, etc. from the internet, and the utility model can notably save the use cost of users for purchasing CD disks, DVD disks, etc.
Description
[technical field]
The utility model relates to a kind of drive unit of USB peripheral hardware.
[background technology]
At present, begun in the whole world popularly as the equipment that is connected with peripheral hardware with USB interface, USB has become hardware device interface commonly used.In audio-frequence player device, use the input interface of USB interface, with the transmission medium of all kinds of flash disks popular on the market as program source as audio signal source.The number of programs of MP3 is many on network, everywhere can free download, be stored into flash disk, portable hard drive etc., i.e. portability, broadcast; It is a most cheap approach of appreciating the various types of programs source.
Because at present, the chip model of popular all kinds of its uses of flash disk has nothing in common with each other on the market, the difference in version of driver is bigger, even some flash disk uses on PC, also needs to adorn in addition driver.Also increased USB interface on the DVD playback equipment of some new model, but operation is more loaded down with trivial details, all undesirable to the compatibility of flash disk, there is flash disk system not discern than polytypic.
[summary of the invention]
The purpose of this utility model is exactly in order to overcome the above problems, provide a kind of compatibility functional, expand the USB peripheral hardware plug-and-play apparatus in the various types of programs source of AV equipment greatly.
For achieving the above object, the utility model proposes USB peripheral hardware plug-and-play apparatus in a kind of AV equipment, comprise USB interface, USB driver module, audio decoder module, detection module, control module, described USB interface output terminal connects the USB driver module, described USB driver module also is connected with the governor circuit of described audio decoder module, detection module, AV equipment respectively, described testing circuit output terminal, audio decoder module output terminal are connected with described control module, and described control module also is connected with AV equipment audio input end, audio frequency processing circuit respectively.
USB peripheral hardware plug-and-play apparatus also comprises the video decode circuit in the above-mentioned AV equipment, is connected respectively with described USB driver module, control module, and described control module also is connected with video inputs, the video processing circuits of AV equipment.
USB peripheral hardware plug-and-play apparatus in the above-mentioned AV equipment, described audio decoder module is the MP3 decoding module.Described video decode module is the mpeg video decode module.
Owing to adopted above scheme, brought following beneficial effect:
Quoted advanced OTG technology in this device,, realized plug and play, the AV compatibility of apparatus is improved by finding, detect, discern, control, playing automatically; By using this device, existing AV equipment is expanded on programme source greatly, can utilize flash disk, portable hard drive etc. to play from the various sounds of the Internet download, video file, has significantly saved the user and has bought use costs such as CD video disc, DVD video disc.
The driver that this installs compatible all kinds of USB peripheral hardwares need not other install driver; Plug-and-play feature is set, and it is convenient and swift that broadcast makes the USB interface application automatically; Can automatically switch between AV sound, video source and USB sound, the video source input; I has been adopted in inside
2The total line traffic control of C, feature operation is carried out in convenient use remote control.
[description of drawings]
Also the present invention is described in further detail in conjunction with the accompanying drawings below by specific embodiment.
Fig. 1 is the utility model embodiment one schematic block circuit diagram.
Fig. 2 is the utility model embodiment two schematic block circuit diagram.
[embodiment]
Embodiment one: as shown in Figure 1, the utility model comprises USB interface, USB driver module, MP3 decoding module, detection module, control module, and the USB driver module adopts USB OTG driver module.Wherein USB interface, USB (OTG) driver module, MP3 decoding module are arranged separately on the double face copper, and the output of control module is drawn with the AN connector interface, to make things convenient for the topological design of integral device; The MCU governor circuit directly utilizes the MCU governor circuit in the equipment such as TV, AV, uses I
2C, I/O connect, and resource sharing is to reduce cost.
When the USB peripheral hardware was gone up in the USB interface grafting, USB (OTG) driver module drove this USB peripheral hardware, and detection module detects USB peripheral hardware existence, MP3 existence, work state information, and testing result is sent to control module; Simultaneously, USB (OTG) driver module is delivered to the MP3 decoding module with the file of MP3 format and is carried out decodes and plays, outputs to control module; Control module selects CD, DVD, the signal of signal sources such as TV, AV or the signal of USB peripheral hardware to play.
Embodiment two: as shown in Figure 2, this example has been set up the mpeg video decode module on the basis of embodiment one, and input end is connected with USB (OTG) driver module, and output terminal is connected with control module.Control module has a video inputs to connect the vision signal of AV equipment, has a video output terminals to be connected with the video processing circuits of AV equipment.Utilize this device, AV equipment can be play-overed the video file of the mpeg format in the USB peripheral hardware.
