In response to an incoming communication request or other interruption, a television signal being currently displayed by an interactive television system is buffered for subsequent playback. In one embodiment, the television signal is automatically buffered immediately upon detection of the request. Alternatively, buffering begins when the request is accepted. Playback of the television signal being buffered may commence, for example, when the request is rejected or after communication with a remote device is terminated.
