A standard target decoder model for MPEG-4 FlexMux streams

MPEG-4, like other MPEG standards is generic and universal in the sense that it specifies compressed bitstream syntax. This, in effect, unambiguously defines the decompression process and the decoder architecture. Further, to ensure interoperability between encoders and decoders, it is essential that a standard target decoder model (STD) be well defined. Since STD is a hypothetical model in the encoder architecture, multiplexors can create compliant streams without having to base their design around any particular decoder. At the same time, compliant decoders should have the minimum buffers as mandated by the STD and hence should be able to decode compliant streams. This paper proposes an STD model for MPEG-4 FlexMux framework
