Abstract

In a generalised hypothetical reference decoder, an encoder provides an encoded video bitstream, using scalable video coding, which may be subject to bitstream rewriting. Bitstream rewriting enables the bitstream to be decoded by devices not compatible with scalable video coding e.g. legacy devices. The encoder further determines a set of parameters for use by a decoder in the event of bitstream rewriting to ensure effective decoding of the video bitstream by the decoder. The set of parameters is introduced in the encoded video bitstream.
