  • Filing of variable-bit-rate video information on zoned disks
    Patent number: 6141493
    Abstract: 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.

  • Transmission of variable-bit-rate information data on constant-bit-rate channel
    Patent number: 6040866
    Abstract: 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.
