The Thor HD-SDI to DVB-T modulators are combination devices that bundle real time HD hardware encoders with a managed program stream multiplexer and agile RF QPSK modulator. Each chassis can encode HD-SDI video to MPEG-2 or H.264 and modulate the programs on DVB-T carrier output. In addition to the encoded programs, the unit can also modulate programs encoded externally via an ASI input. This platform is most commonly used by large organizations or broadcasters that own SDI matrix routers. This platform is ideal for corporate MATV systems or in-house HD video distribution from SDI sources. Designed for high quality distribution of broadcast quality video over coax cable. It is important to note that encoder card types can usually be combined with encoder cards for other video types.
