Abstract: The present invention provides a video-based, combined informational/training system for user activity related applications. In one embodiment, the system (2) includes a video recording assembly (10) and a measuring device (4) located at a user activity site (6) such as a tee box of a golf driving range. A video tape (60), including activity specific information on a first, pre-recorded portion thereof, is provided to the user for use in the video recording assembly (10) at the user activity site (6). The video tape (60) is cued for recording user specific information on a second portion of the video tape (60) during a practice session. The sensor (4) determines corresponding parameter information, such as estimated golf ball carry distance, for display on video tape (60). The video tape (60) and video recording assembly (10) cooperate to provide a mechanism for preventing or discouraging use of unauthorized tapes and to ensure proper usage of the system (2).
