Greylock encodes a 3G SDI or an HDMI source using H.264 compression and has the power to stream 1080p video point-to-point on an internal network, point-to-point over the WAN, multicast to a local network, to a decoder located on a different network, and to online video platforms. Greylock can also be used to decode as well as encode a stream.
