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.

Abstract
A multi-rate encoder includes one or more encoder sets. Each encoder set includes multiple encoders receiving a same video source stream. The encoder sets are configured to transmit multiple encoded streams of the same video source stream at different bit-rates. The streams are aligned and transmitted from the multi-rate encoder.

5. A method of coding a video source stream comprising:
-
receiving an unencoded video source stream at multiple encoders; aligning the unencoded video source stream among the multiple encoders; encoding the aligned unencoded video source stream at each of the multiple encoders to create a service set of multiple encoded video streams of different bit rates; and transmitting the multiple encoded video streams. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
