Abstract

A method, apparatus and system for adaptably distributing video server processes among processing elements within a video server such that video server operation may be adapted in a manner facilitating rigorous timing constraints.

Claims

1. A method, comprising:

associating each of a plurality of processing elements with at least one respective video server process;

assigning priority to said processing elements according to a hierarchy of video server processes, each of said video server processes having a relative priority level with respect to other video server processes;

adjusting said hierarchy of video server processes according to at least one of monitored timing parameters, changes in system loading conditions, changes in operating conditions and operating system scheduler requirements.

2. The method of claim 1, further comprising:

adjusting said associations of processing elements and video server processes in response to at least one of processing element loading, monitored timing parameters, changes in system loading conditions, changes in system operating conditions and operating system scheduler requirements.
