The new USB interface is reversible and can transmit audio and video signals The next generation USB interface that Tencent science and technology sends not long ago no longer has directivity (both sides can be inserted to use) message, let a lot of users feel quite practical. And recently came out a good news, the new USB interface, can also be transmitted audio and video signals, that is, USB cable, may "kill" the traditional HDMI and other audio and video cables and interfaces.
According to TheVerge, the video electronics standards association (VESA) recently announced that the next generation of type-c USB will be able to transmit audio and video using Display Port technology, The interface can even support ultra HD video signals up to 5K.
It is reported that in the 2.0 version of the SPECIFICATION for USB power transmission, there is an extended specification for AlternateMode, which supports the transmission of non-power signals in USB cables.
In this way, the AltMode mode of the DisplayPort interface will be able to transmit DisplayPort audio and video signals using the new USB cable to one, two, or four transmission channels. Most importantly, the transmission of audio and video signals and the transmission of electricity can be carried out simultaneously.
According to industry sources, the new USB port will create a new interface similar to Intel's Thunder Bolt, which will support a wider range of functions, but will require vendors to work with it on the physical side.
According to the media, TYPE-C USB interface is likely to become the future unified cable, replacing all power transmission, audio and video transmission cables.
According to VESA, the new USB port will support HDMI, DVI and VGA, in addition to the DisplayPort video port, with the appropriate adapter.
As we all know, tablets, smartphones and laptops are getting smaller, leaving more and more limited space for external interfaces. If a "multi-functional" USB interface is able to achieve multiple signal transmission, it will benefit the industry.
At present, the new version of Type-CUSB interface has not been put into use or sold. Last month, the specification of this new interface was formally completed, and the Xinjiekou, which supports both sides of the plug, will soon be applied to electronic products.
It is worth mentioning that in the traditional audio and video signal transmission, there have been a variety of interface specifications, there is a competitive relationship between each other. For example, the above DisplayPort hd video interface is a competitor of HDMI and UDI interface.
According to the data, the Display Port is supported by AMD, Intel, NVIDIA, Dell, HP, Lenovo, Philips, and Samsung. The related technologies of the Display Port are provided to the manufacturers for free. HDMI interface support manufacturers mainly from the consumer electronics industry, seven founding manufacturers including Hitachi, Panasonic, Philips, SiliconImage, SONY, Thomson, Toshiba.
