Abstract
Abstract A system and method for simulating the operation of a video disk player playing an interactive video disk, which comprises a video tape player, a timing code reader, a monitor, a computer, and an input device. A control program is entered into the computer through the input device. A video tape is loaded in the video tape player. The video tape player generates video signals and a timing code signal associated therewith. The video signals are displayed on the monitor. The timing code signal is converted into an output signal by the timing code reader. The computer, under operator control, controls the operation of the video tape player, in response to the output signal and the control program such that the video signals displayed on the monitor simulate the operation of a video disk player playing an interactive video disk.

Claim 1
Independent Claim
215 words
A system for receiving control information and video information for simulating the operation of a video disk player playing a disk having video information and control information encoded therein, said system comprising: video tape player means for receiving said video information and for producing video signals in response thereto, said video signals having a timing code signal associated therewith; monitor means for displaying said video signals; timing code signal reading means for receiving said timing code signal and for converting said timing code signal into an output signal representative of a count of the number of picture frames incorporated in the video information from a predetermined starting point; computer means, communicating with said timing code signal reading means for receiving said output signal; and an input device means, communicating with said computer means for supplying said control information to said computer; said computer means being connected to said video tape player means for controlling the operation of said video tape player means in response to said control information and said output signal, such that said video signals displayed on said monitor means simulate the operation of a video disk player playing a disk having video information and control information encoded therein, and wherein said computer means includes operator controllable means for amending said control information.
Claim 2
Independent Claim
215 words
A system for receiving control information and video information for simulating the operation of a video disk player playing a disk having video information and control information encoded therein, said system comprising: video tape player means for receiving said video information and for producing video signals in response thereto, said video signals having a timing code signal associated therewith; monitor means for displaying said video signals; timing code signal reading means for receiving said timing code signal and for converting said timing code signal into an output signal representative of a count of the number of picture frames incorporated in the video information from a predetermined starting point; computer means, communicating with said timing code signal reading means for receiving said output signal; and an input device means, communicating with said computer means for supplying said control information to said computer; said computer means being connected to said video tape player means for controlling the operation of said video tape player means in response to said control information and said output signal, such that said video signals displayed on said monitor means simulate the operation of a video disk player playing a disk having video information and control information encoded therein, and wherein said computer means includes operator controllable means for amending said control information.

Claim 8
Independent Claim
147 words
A method of simulating the operation of a video disk player playing a disk having video information and control information encoded therein, said method comprising the steps of: loading a video tape containing video information in a video tape player means; operating said video tape player means with said video tape to produce video signals and a timing code signal associated with said video signals; displaying said video signals; converting said timing code signal into an output signal representative of a count of the number of picture frames incorporated in the video information from a predetermined starting point; and controlling the operation of said video tape player means in response to said output signal and control information and amending said information to cause said displayed video signals to simulate the operation of a video disk player playing a disk having video information and control information encoded therein.
Claim 9
Independent Claim
147 words
A method of simulating the operation of a video disk player playing a disk having video information and control information encoded therein, said method comprising the steps of: loading a video tape containing video information in a video tape player means; operating said video tape player means with said video tape to produce video signals and a timing code signal associated with said video signals; displaying said video signals; converting said timing code signal into an output signal representative of a count of the number of picture frames incorporated in the video information from a predetermined starting point; and controlling the operation of said video tape player means in response to said output signal and control information and amending said information to cause said displayed video signals to simulate the operation of a video disk player playing a disk having video information and control information encoded therein.
