In this paper, the authors propose a scalable video coding scheme for H.264/AVC video that fully utilizes the benefits of Switching frames (SP/SI) to facilitate user-friendly remote multimedia stream browsing and editing. A content aware rate-control algorithm is developed to adaptively determine the optimal encoding configuration for balancing the trade-off between video coding efficiency and temporal scalability. Their temporal scalable coding scheme is useful for implementing DVCR-like interactive functionality such as fast-forwarding and reversing in multimedia streaming applications such as Video-On-Demand, video broadcasting and remote video editing.
