Abstract:
1. A method of transcoding video content comprising: receiving encoded video content that includes a first set of coded units comprising I-units, P-units and B-units; and transcoding the encoded video content into transcoded video content that includes a second set of coded units comprising I-units and P-units, wherein transcoding includes converting the B-units in the first set into one or more of the P-units in the second set, wherein the B-units include B-video blocks that include temporal predictions based on two different lists of predictive data and include P-video blocks that include temporal predictions based on one list of predictive data, and wherein the P-units include P-video blocks and do not include B-video blocks, wherein for one or more of the B-units in the first set, converting includes: wherein generating the augmented residual block is based on differences between values of the first reference video block from a first one of the two different lists and values of a second reference video block from a second one of the two different lists.
