✦ Synopsis
A model is proposed for replacing the video codec in networking studies, which is tested for sources with a mean bit-rate in the range of 10 Kb/s to 10 Mb/s. The standard frame sizes investigated are the International Telecommunications Union's (ITU) 352;288-pixel Common Intermediate Format (CIF), 176;144-pixel Quarter CIF (QCIF), 704;576-pixel 4CIF and 128;96-pixel Sub-QCIF (SQCIF). The proposed 20-state 'oscillation-scaled' Markov model was found to represent the relevant video codec characteristics adequately. The performance of this model is then tested in the context of a novel Multi-frame Packet Reservation Multiple Access or MF-PRMA scheme, which is shown in Fig. 17 to outperform conventional PRMA in terms of both its delay and packet dropping performance, reaching throughput values as high as 79%.
