Abstract
The present invention provides for gathering and aggregating data related to the functionality of digital video recorders (DVRs) and transmitting updated instructions to the DVRs. During its operation, a DVR gathers data that is relevant to the detection of commercials such as luminance values, commercial patterns, and user input and stores this information in its internal storage. A central server receives updated instructions from administrators and generates new instructions in response to data aggregated from individual DVRs. The central server transmits the updated instructions to remote DVRs.
