碩士 === 國立臺灣大學 === 資訊網路與多媒體研究所 === 96 === The multimedia broadcast/multicast service (MBMS) originally proposed by UMTS supports the delivery of multimedia streams to a group of mobile subscribers. With the heterogeneity of device capability and the variety of subscriber preference, an MBMS source has to provide multiple levels of service quality to its group members. One of the possible ways to achieve this is to incorporate the layer-encoding (i.e., scalable-coding) technique into MBMS. With scalable coding, multiple layers of multimedia data can be encoded, and be properly distributed to various kinds of recipients. This thesis investigates the distribution of layer-encoded multimedia data for MBMS. Specifically, we propose a new channel allocation scheme for layer-encoded MBMS, and develop several allocation policies based on the proposed scheme. The performance of our scheme is evaluated through our developed analytical and simulation models.
