Joint Video Team (JVT) 針對H.264/AVC提出了可調性視訊編碼 (Scalable Video Coding, SVC) 的修正草案,H.264/SVC。經過H.264/SVC編碼後的視訊,可分成與H.264/AVC相容的基礎層與具備可調性的增強層。可調性視訊能讓不同的用戶端,依據本身的狀況或網路的頻寬獲得所需的視訊品質。
本篇論文針對H.264/SVC在IEEE 802.11e傳輸的情況進行探討,並結合網路摘要層 (Network Abstraction Layer) 提出建立於IEEE 802.11e媒介存取控制層的動態優先權調整機制的跨層架構,依據可調性視訊封包的重要性提供差異性服務。網路模擬器Qualnet 4.0模擬的結果,証明我們提出的方法可提供較佳的影像品質。
The scalable extension of H.264/AVC, called H.264/SVC, is a current standardization project of Joint Video Team (JVT). An encoded SVC bitstream consists of an H.264/AVC-compatible base layer and one or more scalable enhance layers. In order to meet requirements of various clients, some scalable enhance layers can be truncated.
This thesis focuses on the investigation of H.264/SVC transmission over IEEE 802.11e through a Cross-layer Architecture. The Cross-layer Architecture, which interacts Network Abstraction Layer and Dynamic Priority Adjustment Mechanism based on IEEE 802.11e MAC layer, provides differentiated services according to the importance of scalable video packets. The simulations are conducted with Qualnet 4.0. The simulation results show that our approach provides better video quality.
