Encoding
The BrightEye NXT 450 Clean Streaming Router contains both a full featured encoder and
a decoder. Because the encoder and decoder are completely independent, they can be
used independently or together.
You can route any 3G/HD/SD SDI baseband source that is connected to the NXT 450 to its
internal MPEG-4 H.264 encoder. The encoder simultaneously produces a high resolution
output for broadcast and a low resolution output for mobile and hand-held devices. The
encoder’s DVB-ASI formatter provides the option of sending encoded signals back to the
routing matrix as a DVB-ASI signal. You can then deliver the signal to a BNC output or to
fiber for delivery to a distant location.
