Here are some additional details about USB AV:
1. USB AV Standards: There are several different USB AV standards that define the protocols and specifications for transmitting audio and video data over USB. The most common standards are USB Video Class (UVC) and USB Audio Class (UAC). These standards define the device classes and the communication protocols used for handling audio and video data.
2. Device Support: Devices must be designed to support USB AV in order to transmit and receive audio and video signals. Most modern devices, such as webcams and external audio interfaces, have built-in support for USB AV.
3. Data Transfer Rates: The USB AV specification supports various data transfer rates depending on the USB version. USB 2.0 supports transfer rates up to 480 Mbps (Megabits per second), while USB 3.0 and later versions provide much faster transfer speeds, enabling high-quality audio and video transmission.
4. Cable Requirements: USB AV typically uses standard USB cables. However, for high-resolution video transmission, such as 4K or 8K, specialized USB cables with higher bandwidth capabilities may be required.
USB AV allows for convenient and versatile connectivity of devices that require audio and video transmission, such as web conferencing systems, live streaming setups, and home entertainment systems. It provides a simplified way to connect and use these devices without the need for separate audio and video cables.
