A method is provided by which a subscriber accesses an SDV channel using a set top terminal. The method begins when the set top terminal receives a user request to tune to a first SDV channel. An active services list is also received over an access network. The active services list includes an entry for each currently available SDV program and a time-to-live (TTL) associated therewith. Tuning information is identified for the first SDV channel from its entry in the active services list. The set top terminal tunes to the first SDV channel using the identified tuning information. The channel change information associated with the user request is locally stored in set top terminal for transmission over the access network at a later time.

A digital agent is pre-trained to be a digital proxy for a user. Taking on the persona (e.g., personality, mannerisms, preferences, knowledge, and in some cases, a realistic visual appearance and voice of the human), the digital agent can effectively act on behalf of the human. During a virtual meeting, the pre-trained digital agent can listen to what the team has to say, ask clarifying questions, answer questions on the human's behalf, and raise points the human would want the team to consider. Since the digital agent visually resembles, sounds like, and acts like the human, the digital agent appears much like other remote participants, thereby improving the meeting experience of the other attendees and facilitating meeting productivity in the absence of a human team member.
