This paper presents an efficient buffer management scheme to support heterogeneous resolution display in home VOD services. The proposed scheme provides different quality services for various home appliances such as digital TV, home theater, and personal digital assistants (PDAs). Specifically, the proposed scheme exploits the reference popularity of video objects as well as the interarrival time between two consecutive requests on the same object. The scheme also considers the different streaming rate of video objects to provide QoS adaptive VOD service for heterogeneous appliances. Experiments with real world VOD traces show that the proposed scheme improves the performance of home VOD systems significantly.
