1. A multi-rate encoder comprising:

  • at least one encoder setincluding multiple encoders receiving a same video source stream and being configured to transmit multiple encoded streams of the same video source stream at different bit-rates;

    wherein each encoder set is configured toalign the same video source stream among the multiple encoders on a same unencoded picture of the same video source stream,align the multiple encoded streams on a corresponding boundary of a same encoded GOP service, andtransmit the encoded GOP service set in alignment;

    the multiple encoders of the at least one encoder set includinga first encoder receiving the same video source stream and encoding the same video source stream at a first bit rate of the different bit-rates; and

    a second encoder receiving the same video source stream and encoding the same video source stream at a second bit rate of the different bit-rates.
