USB-IF announces new USB audio/video device class spec

BEAVERTON, USA: The USB-IF has released the USB-IF Audio/Video Device Class Specification. The specification supports the transfer of A/V data over USB to a wide variety of A/V devices, including cell phones, cameras, pico projectors, webcams, large HD displays and TVs. The A/V Device Class Definition enables manufacturers of small form factor devices to develop single-cable devices, which provide both power and display over one USB cable.

“The USB-IF is thrilled to have added the USB Audio/Visual Device Class Definition to its robust set of specifications,” said Jeff Ravencraft, USB-IF president and COO. “This addition further establishes USB as an all-inclusive, comprehensive solution for manufacturers and consumers, while maintaining the affordability and ease-of-use that have made USB so successful. Continued USB advancements along with the technology’s scalability pave the road ahead for USB.”

USB provides consumers with an affordable, backward compatible solution that supplies not only data transfer, but also simultaneously delivers seamless audio/video capabilities, power, mass storage and more. In comparison, other technologies are designed only for a primary application.

For example, many specifications are designed to just connect mobile phones and portable devices to HDTVs and displays. Additionally, the USB licensing obligation for the new Audio/Video Device Class Specification is on a reciprocal, zero-royalty basis. USB brings to market a complete solution, providing consumers with a myriad of use cases.
