General Details
UHD-Decode is an easy to operate and unconditionally stable Ultra HD HEVC decoder for professional Broadcast applications such as for satellite, terrestrial, cable, OTT operators and IPTV networks, plus any kind of lab and field test experimentation.

UHD-Decode supports HEVC Main and Main 10 encoded transport stream input over IP. The video and embedded audio channels are output over quad 3G-SDI links, or HDMI 2.0 with metadata.

This software based decoder can be used in any conditions either for Ultra HD migration validation, or long test runs, live events contribution and for various 24/7 broadcast monitoring applications. High bit rate contribution decoding is supported.
