A process is provided that may be employed by a set top terminal when a viewer is engaged in a SDV session and is required to switch from one edge device to another. The method begins when a set top terminal receives an SDV program forwarded over an access network by a first digital modulator. The SDV program is received on a first SDV channel associated with the first digital modulator. Next, a request is received to tune to a second SDV channel associated with a second digital modulator to thereby continue receiving the SDV program over the access network. The set top terminal detects an event indicating that a change from the first SDV channel to the second SDV channel will lessen disruption to a viewer of the SDV program. Finally, the set top terminal tunes to the second SDV channel.
