Abstract
A Bandwidth Resolution Conflict component combines control data for multiple controlled devices into a unified control data signal that can be transmitted on a single communication channel. To resolve any bandwidth conflicts, the BCR component implements one or more of the following techniques to resolve the bandwidth conflicts: (1) regenerating the control data signal by increasing at least one compression parameter used in creating the first and second segments of control data; (2) interleaving the control data signal by replacing two adjacent frames of the control data segment with a single frame designated as a repeat frame; (3) reorganizing the control data by moving a frame of control data segment into an unoccupied frame in the control data signal; (4) pre-stuffing the control data signal by moving a portion of the control data to frames in which the moved control data will accumulate for delayed performance in a buffer in one of the controlled devices; and (5) selecting one of the controlled device for data starving based on predefined selection criteria and deleting one or more frames of the control data for the selected controlled device. One or more of these techniques m…
