The architecture of the Berkeley Distributed Hierarchical Video-On-Demand (VOD) system consists of Continuous Media Servers (CMS) basically standing as a cache between the Archive Servers (AS) and the clients. In this paper, we first describe the features of a new cache management algorithm called Adaptive Viewers Bias Based (AVBB). With a firm belief that some video viewers can settle for some video other than that of their first choice, we then propose making the cache transparent of its video contents to the viewers as a technique to improve cache performance. Finally, we evaluate the improvement cache transparency brings to AVBB.
