在現在的無線通訊裡，對於視訊影像的傳輸是很重要的一部份。對於資源分配的機制來說，服務品質(QoS)的支援是非常重要的。我們針對可調性視訊編碼(Scalable Video Coding, SVC)，計算每層資料的通道失真量，以此為一個新的參數帶入MAC層的資源分配機制；考慮實體層的無線通道，再納入adaptive modulation and coding(AMC)的機制，如此通過跨層的資訊考慮，設計出一個動態資源分配的方法，可適應無線網路的通道變化與應用層視訊影像的特性。

Video transmission plays an important role in wireless communication. For resource allocation mechanism, it needs to support quality of service (QoS). We calculate channel distortion of each layer in Scalable Video Coding (SVC) as a new parameter for resource allocation mechanism. We employ adaptive modulation and coding (AMC) scheme for wireless channel at the physical layer. Then the resource allocation mechanism we designed is suitable for the time-varying wireless channel and the characteristic of video streaming.
