• means for operating the means for inhibiting to inhibit said television receiving device from reproducing said selected program if it is determined that said apparatus is not authorized to reproduce said selected program;
• and
• means for reproducing from said recording medium said selected program if it is determined that said apparatus is authorized to reproduce said selected program.

Apparatus for selectively inhibiting a television receiving device from recording and/or reproducing video programs which are not authorized for viewing, comprising:

• means for receiving a video program;
• a memory for storing program information associated with programs that are recordable and reproducible by said television receiving device, said program information including record medium identification data and authorization data indicating whether said apparatus is authorized to record and/or reproduce said received program;
• means for reading from said memory the authorization data associated with said received program to determine if said apparatus is authorized to record said received program;
• means for inhibiting said television receiving device from recording said received program if it is determined that said apparatus is not authorized to record said received program;
• means for recording said received program on a video record medium if it is determined that said apparatus is authorized to record said received program;
• means for selecting a program to be reproduced from said video record medium;
• means for generating a list of authorized programs and said record medium identification data, each program being associated with respective record medium identification data that identifies the record medium on which that program is recorded;
• means for comparing the record medium identification data of said record medium to the record medium identification data of said generated list to determine if the authorization data associated with said selected program is present in said memory and wherein said reading means is operable to read from said record medium the authorization data associated with said selected program if it is determined that said authorization data associated with said selected program is not present in said memory, and is operable to read from said memory the authorization data associated with said selected program to if it is determined that said authorization data associated with said selected program is present in said memory;
• means for operating the means for inhibiting to inhibit said television receiving device from reproducing said selected program if it is determined that said apparatus is not authorized to reproduce said selected program;
• and
• means for reproducing from said video record medium said selected program if it is determined that said apparatus is authorized to reproduce said selected program.

Method of selectively inhibiting a television receiving apparatus from reproducing from a recording medium video programs which the apparatus is not authorized to reproduce, comprising the steps of:

• reading from a memory program information associated with programs that are reproducible by said apparatus, said program information including authorization data indicating whether said apparatus is authorized to reproduce one or more of said associated programs, and said authorization data including authorization status information indicating whether said apparatus has a limited or complete authorization to reproduce one or more of said associated programs, expiration date data representing the last date said apparatus with said limited authorization status is authorized to reproduce said one or more associated programs, and price data representing additional payment required to change the authorization status of said apparatus with said limited authorization status to said complete authorization status;
• selecting a program to be reproduced from said recording medium;
• reading from said memory the authorization data associated with said selected program to determine if said apparatus is authorized to reproduce said selected program;
• inhibiting said apparatus from reproducing said selected program if it is determined that said apparatus is not authorized to reproduce said selected program;
• and
• reproducing from said recording medium said selected program if it is determined that said apparatus is authorized to reproduce said selected program.

Method of selectively inhibiting a television receiving apparatus from reproducing from a video record medium video programs which the apparatus is not authorized to reproduce, comprising the steps of:

• reading from a memory program information associated with programs that are reproducible by said apparatus, said program information including includes record medium identification data to uniquely identify said record medium and authorization data indicating whether said apparatus is authorized to reproduce one or more of said associated programs;
• recording on said record medium said program information associated with programs recorded on said record medium;
• selecting a program to be reproduced from said video record medium;
• generating a list of authorized programs and said record medium identification data, each program being associated with respective record medium identification data that identifies the record medium on which that program is recorded;
• comparing the record medium identification data of said record medium to the record medium identification data of said generated list to determine if the authorization data associated with said selected program is present in said memory;
• reading from said memory the authorization data associated with said selected program to determine if it is determined that said authorization data associated with said selected program is present in said memory;
• and reading from said record medium the authorization data associated with said selected program if it is determined that said authorization data associated with said selected program is not present in said memory;
