What is the difference between EtherCast and a video encoder/decoder?
A video encoder compresses/encodes the data and transmits it over an IP network. The latency is usually adjustable, with a range of from 350 ms to several seconds. At the receiving end, the video decoder decompresses/decodes the data. Video encoders/decoders are based on embedded processors with software operating systems. In contrast, EtherCast does not compress the video stream, but can be used in conjunction with video encoders. EtherCast gateways are based on purpose-built hardware, with patent-pending techniques to reduce latency and improve reliability.
