Abstract
A method and apparatus for managing both link and disk bandwidth utilization within the context of a multiple subscriber or user information distribution system by selectively providing variable bitrate and constant low bitrate information streams to one or more subscribers.
Claims1
In an information distribution system, apparatus comprising:
- a storage unit, for storing a plurality of programs, each program being associated with a relatively high bitrate information stream and a corresponding relatively low bitrate information stream;
- a server, for retrieving one or more of said programs from said storage unit, said storage unit selectively multiplexing, for each retrieved program, a respective one of said relatively high bitrate information stream and said corresponding relatively low bitrate information stream to form a multiplexed information stream;
- and
- a communications link having a finite bandwidth, for transporting said multiplexed information stream;
- wherein
- said server preferentially multiplexing said relatively high bitrate information stream associated with each of said retrieved programs;
- said server, in response to a condition of insufficient communication link bandwidth, multiplexing said respective relatively low bitrate information stream associated with one or more of said retrieved programs.
