Abstract
A system for receiving and analyzing at least one inband user data packet within a CATV video signal. The system includes a data detector, a data processor and a memory. The data detector receives video signal samples of the data packet. The data detector includes a data slicer used to determine a threshold level based on a clock sync byte located in the data packet. The threshold level is compared to subsequent video signal samples of the data packet. The data processor determines the destination of the data packet. The memory selectively stores the data packet until it is required by the data processor.
