1. A video recording playing method comprising the steps of:
- receiving, from a video storage medium, signals representative of a video program,processing said signals to produce video signals of a form suitable for display,detecting a classification code within the signals received from the storage medium, said detected code being indicative of a class of program being played,inputting from the user a security code number, comparing the number input to a stored number and, if the numbers are equal, enabling selection of a set of classification codes which cause at least one of suspension or termination of playing,comparing the detected code to said set of classification codes, andselectively playing the video program according to the result of the comparison.

Abstract
A classification code, recorded repeatedly along with program material, is recovered on playing a video recording, and used to inhibit replay if the recovered code matches any of a set of codes specified by the user. The codes which cause replay to be inhibited can be set by the user after entering a personal identity number. The user can optionally request that a code be recorded when recording a program. Signals are optionally provided so that an auxiliary device, such as a second video player, can be controlled in response to codes recovered. One application is to prevent children viewing certain video recordings without parental permission.

7. A video recording playing method comprising the steps of:
-
receiving, from a video storage medium, signals representative of a video program, processing said signals to produce video signals of a form suitable for display, detecting a classification code within the signals received from the storage medium, said code being indicative of a class of program being played, comparing the detected code to a set of selected codes, selectively playing the video program according to the result of the comparison, and transmitting to an auxiliary device a signal indicating the classification of program being replayed.

8. A video recording playing method comprising the steps of
receiving from a video storage medium signals representative of a video program, processing said signals to produce video signals of a form suitable for display, detecting a code within the signal received from the storage medium, comparing the detected code to a set of selected codes, and, according to a predetermined result of the comparison: -
sending a signal to an auxiliary device, causing playing of the video program to be suspended, waiting until a resumption signal is received, and resuming replay of the suspended program after receiving the resumption signal. - View Dependent Claims (9, 10, 11)

12. A video recording player which displays video on a video display means, comprising:
-
means for receiving, from a video storage medium, signals representative of a video program, processing means for converting said signals into video signals of a form suitable for application to the video display means, means for detecting a classification code within the signal received by the receiving means, said code being indicative of a class of program being played, input means for accepting from the user a security code number; enabling means for enabling selection of a set of classification codes which cause suspension or termination of playing, said enabling means enabling said selection only if the security code number input is the same as a stored security code number, means for comparing the detected code to said set of classification codes, and controller means for selectively playing the video program according to a result of the comparison. - View Dependent Claims (13, 14, 15, 16, 17)

19. A video recording player comprising:
-
means for receiving, from a video storage medium, signals representative of a video program, processing means for forming video signals of a form suitable for application to a video display means from said signals, means for detecting a code within the signal received by the receiving means, means for comparing the detected code to a set of selected codes, and controller means for, according to the result of the comparison, sending a signal to an auxiliary device, to cause playing of the video program to be suspended, and responsive to a resumption signal to resume playing of the suspended program when the resumption signal is received. - View Dependent Claims (20, 21, 22)
