Employing H.264 Coarse And Medium Grain Scalable Video To Optimize Video Playback Over Passive Optical Networks, David Moore
Employing H.264 Coarse And Medium Grain Scalable Video To Optimize Video Playback Over Passive Optical Networks, David Moore
Honors College Theses
In this work, we propose the use of Coarse Grain Scalable (CGS) and Medium Grain Scalable (MGS) H.264/AVC video to optimize video playback on passive optical networks (PONs) by investigating network performance metrics such as data delay, video delay, and video delay jitter. Video playback is improved by sequentially dropping layers of scalable video. Dropping just a single CGS enhancement layer results in improvements of up to 57% for both data and video delay. However, video delay jitter benefits the most with an improvement ranging from 47% to 87%. Surprisingly, dropping subsequent CGS enhancement layers does not significantly improve the …
