1. A method for encoding video data, said method comprising:

  • a) receiving a high dynamic range (HDR) image sequence;

    b) creating a standard dynamic range (SDR) image sequence from said HDR sequence;

    c) encoding said SDR image sequence with an SDR encoder;

    d) transmitting said encoded SDR sequence to a recipient;

    e) decoding said encoded SDR sequence;

    f) inverse tone mapping said decoded SDR sequence to form a decoded HDR sequence;

    g) combining said decoded SDR sequence data, said decoded HDR sequence data and said HDR image sequence to form HDR residual data; and

    h) transmitting said HDR residual data to said recipient.
