Date2017-01


Semisky car audio video bridging Ethernet Technology (Ethernet Audio/Video Bridging Ethernet, hereinafter referred to as AVB) is a new IEEE 802 standard, which is based on traditional Ethernet network, the bandwidth guarantee (Bandwidth), (Latency) and the exact limit delay step (Time synchronization), Shi Zhongtong provides the perfect quality of service (Quality of Service), to support a variety of network multimedia application based on audio and video. Ethernet AVB focuses on enhancing the real-time audio and video performance of traditional Ethernet, while maintaining a 100% backward compatible with traditional Ethernet, is a very promising development of the next generation network audio and video real-time transmission technology.
