sentences:  These two groups created the Joint Video Team (JVT) to develop the H.264/MPEG-4 AVC standard.The objective of the SVC standardization has been to enable the encoding of a high-quality video bitstream that contains one or more subset bitstreams that can themselves be decoded with a complexity and reconstruction quality similar to that achieved using the existing H.264/MPEG-4 AVC design with the same quantity of data as in the subset bitstream.The subset bitstream is derived by dropping packets from the larger bitstream.
