Abstract
Video image information is received in a signal including conditional access information. The conditional access information is associated with one of a plurality of picture resolution formats for recording, reproducing and displaying the video image information. The conditional access information in the received signal is decoded. A format for at least one of recording, reproducing and displaying the video image information is adaptively selected in response to the decoded conditional access information. The video image information is then processed using the selected format. The conditional access information may further include information indicating a predetermined time period during which reproduction of recorded video image information is permitted.
Claims29
A method of selecting a format for displaying video image information received in a signal including conditional access information, said method comprising the steps of:
- a) receiving said signal including video image information and conditional access information associated with one of a plurality of picture resolution formats;
- b) decoding said conditional access information in said received signal, wherein said decoded conditional access information comprises data relating to picture resolution formats available for at least one of:
- i) recording said video image information;
- and
- ii) reproducing said recorded video image information;
- and
- data controlling subsequent copying of said recorded video image information
- c) adaptively selecting a picture resolution format in response to said decoded conditional access information;
- and
- d) processing said video image information using said selected picture resolution format.
A method of selecting a format for displaying video image information received in a signal including copy protection information, said method comprising the steps of:
- a) receiving said signal including video image information and copy protection information associated with one of a plurality of display formats;
- b) decoding said copy protection information in said received signal, wherein said copy protection information comprises data relating to display formats available for at least one of:
- i) recording said video image information;
- and
- ii) reproducing said recorded video image information;
- and
- data controlling subsequent copying of said recorded video image information
- c) adaptively selecting a format for displaying said video image information on a display in response to said decoded copy protection information;
- and
- d) processing said video image information using said selected display format.
A method of selecting a format for recording video image information received in a signal including copy protection information, said method comprising the steps of:
- a) receiving said signal including video image information and copy protection information associated with one of a plurality of recording formats wherein said copy protection information also controls subsequent copying of said video image information;
- b) decoding said copy protection information in said received signal;
- c) adaptively selecting a format for recording said video image information on a recording medium in response to said decoded copy protection information;
- and
- d) processing said video image information using said selected recording format.
