Abstract
A CATV system including a CATV network, a multiplicity of subscriber units, apparatus for transmitting over said CATV network encrypted information individually addressed to a subscriber unit and apparatus associated with each of said multiplicity of subscriber units for decoding the encrypted information addressed thereto.
Claims15
A CATV method for use with a CATV network and a multiplicity of subscriber units, the method comprising:
- determining a collision between non-real-time individually addressed information transmitted to a subscriber unit and at least one of the following types of non-real-time non-video data:
- CATV management data transmitted to the subscriber unit;
- and
- subscriber's program viewing data transmitted to the subscriber unit,
- wherein the individually addressed information does not comprise either of the following:
- a program ordered by a user of the subscriber unit;
- and
- messages and billing data related to programming;
- and
- assigning one of the following in accordance with at least one predetermined criterion:
- a higher priority to the CATV management data and the subscriber's program viewing data than to the individually addressed information;
- and
- a lower priority to the CATV management data and the subscriber's program viewing data than to the individually addressed information.

A headend in a CATV network, the headend comprising:
- determining circuitry operative to determine a collision between non-real-time individually addressed information transmitted to a subscriber unit and at least one of the following types of non-real-time non-video data:
- CATV management data transmitted to the subscriber unit;
- and subscriber's program viewing data transmitted to the subscriber unit, wherein the individually addressed information does not comprise either of the following:
- a program ordered by a user of the subscriber unit;
- and
- messages and billing data related to programming;
- and
- a processor operatively associated with the determining circuitry and operative to assign one of the following in accordance with at least one predetermined criterion:
- a higher priority to the CATV management data and the subscriber's program viewing data than to the individually addressed information;
- and a lower priority to the CATV management data and the subscriber's program viewing data than to the individually addressed information.

A headend in a CATV network, the headend comprising:
- determining means for determining a collision between non-real-time individually addressed information transmitted to a subscriber unit and at least one of the following types of non-real-time non-video data:
- CATV management data transmitted to the subscriber unit;
- and subscriber's program viewing data transmitted to the subscriber unit, wherein the individually addressed information does not comprise either of the following:
- a program ordered by a user of the subscriber unit;
- and
- messages and billing data related to programming;
- and
- processing means for assigning one of the following in accordance with at least one predetermined criterion:
- a higher priority to the CATV management data and the subscriber's program viewing data than to the individually addressed information;
- and a lower priority to the CATV management data and the subscriber's program viewing data than to the individually addressed information.
