ABSTRACT:
A method, apparatus and system for synchronizing the video output of personal video recorders in two or more locations. A broadcast program is received and recorded on a personal video recorder on a first personal video recorder. Thus, at least one program will be stored in memory in the first personal video recorder. A second personal video recorder having a common program residing in its memory is selected. A signal is then transmitted to or from the first personal video recorder to simultaneously initiate a start sequence in each of the first and second personal video recorders. The start signal may be transmitted over the Internet or by other communication means such as telephone lines.
