Abstract : The scalability extension of H.264/AVC uses a layered MCTF approach for providing spatial, temporal, and SNR scalability. The underlying MCTF decomposition scheme generally results in a large structural encoding-decoding delay, which prevents the use in low-delay applications. In this paper we present a new strategy for restricting the MCTF decomposition in way that arbitrary maximum structural delays can be adjusted. Based on this approach, the impact of the encoding-decoding delay on the coding efficiency of the scalable extension of H.264/AVC is analyzed.
