A method and apparatus are disclosed for providing a television viewer with a summary of a portion of a program that he or she has missed, after switching to the program at some time after the program has begun. Generally, the times at which the viewer first tuned to a program, left the program and then returned to it would respectively be monitored. A summary for a missed portion of the program, as determined from these times, would then be furnished to the viewer. In a useful embodiment of the invention, a method is carried out in association with an array of data transmission channels, wherein the channels are respectively connectible to a video receiver or like device, and video content is simultaneously transmitted through each of the channels. The receiver is operated to display the video content transmitted through a first one of the channels during a first time period, and to display the video content transmitted through a second one of the channels during a second time period that follows the first time period. The method further comprises generating a summary of the video content transmitted through the second channel during the first time period, and then presenting the summary to a user of the video receiver during the second time period.
