Disk Partitioning Technique for Reducing Multimedia Access Delay
Paul Bocheck, H. E. Meadows · 1999
With the introduction of future multimedia services such as HDTV, digital systems able to store and retrieve a huge amount of video and audio information will play an important role. One of the key problems is the multimedia data access optimization. In this paper we compare several techniques proposed for storage of multimedia information on the hard disk and introduce a Disk Partitioning Technique allowing an increase in the number of concurrent users while minimizing the required buffer size. Also the support for interactive control such as pause or reverse is demonstrated. Keywords: multimedia retrieval, disk storage, video server I. Introduction Problem of storage and retrieval of delay sensitive information recently received a lot of attention. This paper investigates a problem of efficient placement and retrieval of multiresolution video streams (HDTV) under constraints of real-time and interactive service. Real-time retrieval generally involves two issues. The first addresses...
