ABSTRACT:
An association table associates each program stream of a plurality of program streams with a MAC domain, with a channel frequency and with a multicast address. If a subscriber device selects a content program different from a current program, a determination is made whether the new program is serviced by a different MAC domain than the one serving the current program. If the selected new program is not serviced by the same domain that is serving the current program stream(s), the current MAC domain is informed that the subscriber device is ending the session therewith, the new frequency is tuned by the subscriber device and new content is received immediately after the new frequency is tuned. The subscriber device registers with the new MAC domain after receipt of new content has begun.
