Abstract
A command controller reads and extracts predetermined key words and parameters from a configuration file. The command controller inserts digital data into a television signal according to the extracted predetermined key words and parameters. The command controller initiates a self-recovery operation to purge stored data and re-initialize the VBI inserter based on the extracted predetermined key words and parameters and time or access time. The command controller also extracts digital data from another video signal to be compared to stored diagnostic data or transmitted to another external source.
