Paper Abstract

In this paper, the conformance of hypothetical reference decoder (HRD) is addressed for H.264 when there is jitter among the transmission of packets via a channel without packet loss but variation among transmission delay. The sending rate is decoupled from the coding one. Both the jitter and the total size of coded bitstream are taken into consideration such that the values of buffer size and initial buffer delay are minimized, especially when the sending rate is greater than the coding one. Sufficient conditions are derived for the conformance of a coded bitstream to a HRD at the constant delay. These conditions are then used to design iterative algorithms to determine a minimal buffer size and a minimal initial buffer delay for the decoder. A novel interpolation method is also presented such that it is suitable for a wide range of sending rates.
