14. A digital home communication terminal (DHCT) that is configured to receive user input specifying whether access is to be provided after a future change in a displayed television channel to a buffered video presentation that is buffered before the future change in the displayed television channel, the DHCT comprising:
-
a time-shift buffer (TSB) for buffering the buffered video presentation; and a processor that is programmed to; provide the access to the buffered video presentation responsive to the user input specifying that the access is to be provided; and prevent the access to the buffered video presentation responsive to the user input specifying that the access is not to be provided. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A method for providing access to buffered data, the method comprising:
-
receiving user input specifying whether access is to be provided after a future change in a displayed television channel to a buffered video presentation that is buffered before the future change in the displayed television channel; providing the access responsive to the user input specifying that the access is to be provided; preventing the access responsive to the user input specifying that the access is not to be provided; wherein the access is provided via a rewind operation; wherein the buffered video presentation is buffered in a time-shift buffer (TSB); wherein the TSB corresponds to a portion of a hard disk; wherein the buffered video presentation corresponds to a video stream that is received via a subscriber television network; and wherein the user input identifies an option that is provided via a user interface screen.
