現代網路中對於多媒體應用的需求愈來愈高,傳統影音格式在現今多變的無線網路環境中漸漸無法以有效率的方式傳遞。而 JVT (Joint Video Team) 針對當今熱門的 H.264/AVC 影像格式提出了可適性視訊編碼 (Scalable Video Coding, SVC) 的規範 H.264/SVC,對於上述的問題提出了一個可行的解決方案。
有基於多變的無線網路環境需求,本論文在IEEE 802.11環境中提出一個高效率且反應迅速的傳輸方式,依據無線網路情況決定傳輸的影像品質,可有效在多變的無線網路環境中在影像品質與網路頻寬需求之間取得一個非常良好的平衡。
As the increasing of the multimedia applications demand, the transmission on traditional video format has the lower efficiency the modern rapidly changed network environments. The Joint Video Team (JVT) announced the H.264/SVC (Scalable Video Coding) standard as a resolution to the above problem.
Because of the demand for rapidly changed wireless network environment, here is a high efficiency and fast responding transmission method on IEEE 802.11 we proposed. The transmitting video quality is based on the wireless network conditions, and it has a good balance between the video quality and the network bandwidth required in the varied network environments.
