Block diagram

The input to the encoder is HD-SDI or HDMI.
For the input signal, video, audio (up to 8x stereo pair) is separated,
Sounds in stereo pairs are passed to the encoder according to their encoding settings.
With DTA - 2180, it is also possible to output Dolby Metadata in RDD 6 included in the SDI input signal.
