Description
Technical Field
The invention relates to the field of interface adapters, in particular to an interface adapter with multiple interface matching functions.
Background
The VGA interface is an interface that transmits analog signals to a display. This is an input interface from a computer, and since the CRT display cannot directly receive the input of digital signals, the graphic card can only obtain pictures by inputting analog signals into the display. The VGA interface is provided with 15 pinholes in total and is divided into three rows of five. The VGA interface is the most widely used interface type on the video card, and most video cards have such an interface. The DVI interface is an all-digital transmission interface and can directly transmit digital signals to a display without conversion.
The HDMI interface is a recently developed interface, which uses full digital signal transmission as in the DVI, but it is different from the HDMI interface in that it can not only provide full digital video signals, but also transmit audio simultaneously. The method seems to return to a radio frequency interface in the cable television, and the situation that the image quality is poor due to video and audio interference like radio frequency cannot occur by adopting full digital signal transmission. The HDMI has the greatest advantage that simultaneous transmission of audio and video signals is realized by one cable, unlike the prior art that a plurality of cables are used, and the wiring complexity is greatly reduced. The high-definition digital video and up to 8-channel audio signals which are not compressed are provided while the wires are simplified, the bandwidth with the highest data transmission speed of 5Gbps is possessed, a user can fully enjoy high-quality digital entertainment experience, and the high-definition digital video and audio transmission interface is a real video and audio transmission interface in the HDTV era.
Although various interfaces have their own characteristics and are widely applied to our lives, the trouble brought by the same is that the various interfaces cannot directly convert signals, the corresponding conversion interfaces are required to be used for connection, and the conversion among the various interfaces inevitably causes switching disorder and is inconvenient to use.
