ABSTRACT:
An M-CMTS compatible UEQAM device implements circuitry to identify and analyze MAP message in the data stream sent from the M-CMTS Core with respect to timing information embedded in those messages. The improved UEQAM will then create a specific message as an extension to DEPI to communicate that information to the M-CMTS Core. The M-CMTS Core will employ that analysis to automatically adjust MAP message advance time to reduce delay and thus improve system performance. This invention will provide a closed-loop between the M-CMTS Core and the UEQAM where valuable transmission information will periodically be fed back from UEQAM-to-M-CMTS Core in real-time.
