Abstract

A method and apparatus for effectuating transmission, reception, and processing of source program signals representative of a multimedia program between a remote multimedia server and a plurality of local set-top control systems are disclosed. The multimedia server processes stored digitally compressed multimedia programs preferably by parsing a selected multimedia program into a customized series of discrete program segments, and transmitting the compressed program segments to a local set-top control system, which buffers and decompresses the compressed program segments for presentation on a local display monitor. A local set-top control system preferably includes a direct access storage device adapted to buffer a predetermined number of compressed program segments received from a multimedia server, some of which may be non-sequentially ordered and others of which may be sequentially ordered. A novel formatting methodology provides for the sequential presentation of the program segments asynchronously distributed on one or more data storage disks disposed in the direct access storage device. A user-definable presentation control window for performing local VCR-type presentation control functions for the portion of a multimedia program buffered in the direct access storage device is also provided through the novel formatting methodology. The novel formatting methodology also provides concurrent presentation and buffering of program segments received from the multimedia server for on-demand viewing of a selected multimedia program.
