Scalable video coding (SVC) is a new coding paradigm in contrast to the conventional single-layer video coding. SVC enables an encoded video to be utilized in more flexible ways. In this paper, we combine the H.264 SVC with the content delivery network (CDN) to offer better video services. In particular, a new algorithm for layer arrangement and assignment of H.264 SVC is proposed. Experimental results show that the proposed method greatly reduces the latency for end users to receive the desired video service.
