Architecture for filing variable-bit-rate (VBR) video data on zoned disks based on the character of the VBR data and the character of the zoned disk. A 'constant read-time' approach is disclosed to determine the filing layout of data. In this invention, the distribution of the data is determined by the sequence of retrieving the data. A multistage graph is used to describe the structure of the filing architecture of this invention. The invention also provides a segmentation algorithm to reduce time and space complexities in the processing of VBR data.

Filing of variable-bit-rate video information on zoned disks

A method for transmitting information data with a variable bit-rate (VBR) on a transmission channel with constant bit-rate (CBR) uses both a 'lazy' algorithm and an 'aggressive' algorithm. The 'lazy algorithm' determines a transmission schedule where the smallest client buffer requirement and shortest working-ahead under a decided transmission rate may be obtained. The 'aggressive algorithm' determines a transmission schedule whereby the highest utility rate of the network under a specific client buffer size may be obtained.
