摘要: Abstract : During the past year, we continued our efforts in areas of video compression and storage 1, 2. We have developed three strategies for placement Constant Bit Rate (CBR) data on parallel disk arrays. Using a low-level model from scalable subband coding technique, derived constraints with which to compare strategies. In doing so, found one strategies, constant frame grouping, be superior other two. addition, two methods interleaving multiple videos under grouping strategy been developed: nonperiodic periodic. Periodic is shown advantages lower access time limited scan pause functions. The was tested an actual array 8 disks performance that close theoretical prediction. nature compressed used relieve system overload overly high request rate.
