Summary:Techniques and tools are described for using a signaled or derived buffer fullness value to determine a decoding time stamp. The decoding time stamp can be used in a layer such as a system layer to determine when an access unit such as a coded representation of a field or frame should be decoded. For example, a decoding time stamp that corresponds to a clock cycle of a decoder is determined based at least in part on a hypothetical reference decoder initial buffer fullness value. An initial data access unit of a bitstream is transferred to the decoder for decoding at about the time of the corresponding clock cycle for the decoding time stamp.
