Abstract
An HDMI (High-Definition Multimedia Interface) conversion line, mainly solving the connection problem of an apparatus with HDMI interfaces and an apparatus with VGA (Video Graphics Array) interfaces, comprises a bidirectional converter, an HDMI interface, a VGA interface and an audio line interface. The HDMI conversion line is characterized in that one end of the bidirectional converter is connected with the HDMI interface, and the other end is connected with the VGA interface and the audio line interface. The HDMI not only can convert an HDMI signal into a VGA signal and an audio signal, but also can convert the VGA signal and an audio signal into an HDMI signal, so as to effectively solve the connection problem of the apparatus with HDMI interfaces and the apparatus with VGA interfaces. In addition, the HDMI conversion line can reduce the number of audio signal lines so as to beautify the arrangement of connection lines between apparatuses.
Description
Technical field
The utility model relates to a kind of digital audio-video signal conversion line, and specifically a kind of HDMI changes VGA and audio frequency bidirectional switching signal line.
Background technology
At present, products such as desktop computer, notebook computer, LCD TV, plasm TV are more and more universal, and people also combine use to them, gradually closely to satisfy the more needs of enjoying when enjoying happy that various products bring.Yet the audio-video signal interface that products such as present most of desktop computers, notebook computer, LCD TV, plasm TV have is also inequality, and the connection that has between the equipment of HDMI interface or VGA interface is very convenient.But, if have the HDMI interface not with the desktop computer of VGA interface or notebook computer with having the VGA interface not LCD TV or the plasm TV with the HDMI interface be connected, or have the VGA interface and not with the desktop computer of HDMI interface or notebook computer with having the HDMI interface not LCD TV or the plasm TV with the VGA interface be connected, have the equipment of HDMI interface like this and have interconnecting but between the equipment of VGA interface and brought inconvenience to people.
The utility model content
For overcoming the deficiency that above-mentioned prior art exists, technical problem to be solved in the utility model is to provide a kind of HDMI conversion line, not only solve the equipment that has the HDMI interface and had interconnective problem between the equipment of VGA interface, but also reduced the quantity of audio-video signal line.
The technical scheme in the invention for solving the technical problem is: this kind HDMI changes line, comprise bidirectional transducer, HDMI interface, VGA interface and tone frequency channel wire interface, it is characterized in that described bidirectional transducer one end connects the HDMI interface, the other end connects VGA interface and tone frequency channel wire interface.
The beneficial effects of the utility model are, this kind HDMI conversion line not only can be the HDMI conversion of signals VGA and audio signal, and VGA and audio signal are converted to the HDMI signal, it has solved the equipment that has the HDMI interface effectively and has had interconnective problem between the equipment of VGA interface, also reduce the quantity of audio-video signal line, increased the attractive in appearance of line between the equipment.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified
Fig. 1 is a structural representation of the present utility model;
Wherein: 1 bidirectional transducer, 2HDMI interface, 3VGA interface, 4 tone frequency channel wire interfaces.
Embodiment
As shown in Figure 1, this kind HDMI changes line, comprises bidirectional transducer 1, HDMI interface 2, VGA interface 3 and the tone frequency channel wire interface 4 that can realize HDMI signal and VGA signal and audio signal and change mutually.Be connected to HDMI interface 2 at bidirectional transducer 1 one ends, the other end connects VGA interface 3 and tone frequency channel wire interface 4.
This kind HDMI conversion line not only can be the HDMI conversion of signals VGA signal and audio signal, and VGA signal and audio signal are converted to the HDMI signal, it has solved the equipment that has the HDMI interface effectively and has had interconnective problem between the equipment of VGA interface, also reduce the quantity of audio-video signal line, increased the attractive in appearance of line between the equipment.
