Abstract: Apparatus and method are presented for measuring the transmitter and antenna system time delay (TAD) of the cadence sync at the input of a conventional 8 VSB data processing system until the emission of the segment sync of the corresponding data frame sync data segment. This includes sequentially conditioning a multi-bit input digital signal containing an initial cadence sync, inserting data patterns into the digital signal, inserting a known data pattern into the data frame at a known position of the data frame and receiving the cadence sync and the known pattern and measuring the time delay therebetween.

Abstract: Systems and methods are provided for communication via address modulation on an communication channel. A first processing component is configured to produce a plurality of data packets. Each data packet has an associated address from a plurality of available addresses. The system further comprises a plurality of addressable entities, with each of the addressable entities being represented by a proper subset of at least two of the available addresses. A second processing component is configured to apply at least one conditioning process to the series of data packets. The first processing component is configured to select an address for each packet from the subset of available addresses representing the addressable entity associated with the packet as to communicate data between the first processing component and the second processing component.
