• acquiring a second content;
• outputting the first content, the outputting including outputting of a first video signal on a display;
• and
• switching output from the first content to the second content or switching back output from the second content to the first content based on second trigger information within the television broadcast signal, the second trigger information being associated with a trigger, the switching including switching to output of a second video signal on the display in response to switching to the second content;
• wherein the trigger is one of a plurality of triggers together prompting the switch of output from the first content to the second content, and
