Video coupler using wavelength division multiplexing

A decoder apparatus comprising:

• a decoder transceiver to receive and transmit transport blocks via an optical transport link defining a plurality of optical channels using wavelength division multiplexing;
• a decoder output to transmit at least native video data;
• and
• processing circuitry operatively coupled to the decoder transceiver and the decoder output and configured to:
• receive transport blocks from one of the plurality of optical channels using the decoder transceiver, each transport block comprising a video segment of a video frame of native video data;
• reconstruct the native video data based on the received transport blocks;
• transmit the native video data using the decoder output;
• generate a return-path transport block comprising a source address and an input command;
• and
• transmit the return-path transport block via the optical transport link using the decoder transceiver.
