1. A method of distributing content, comprising:
- associating at least one authorized display mode with the content;
generating a transport stream that includes the content and the at least one authorized display mode;
encoding the transport stream;
transmitting, by a first device, the transport stream having been encoded;
receiving, by a second device, at least one device display mode;
decoding the transport stream to generate the content and the at least one authorized display mode;
comparing the at least one device display mode and the at least one authorized display mode; and
outputting the content according to a result of the comparing.

Abstract
In one embodiment the present invention includes a system and method of distributing content. Authorization information is encoded with the content. When received and decoded, if a particular device output is authorized by the authorization information, then the content is output. By encoding the authorization information along with the content, unauthorized display of the content is reduced.

8. A device for displaying content, comprising:
-
a decoder that receives an encoded transport stream, wherein the encoded transport stream includes the content and at least one authorized display mode, and that decodes the transport stream to generate the content and the at least one authorized display mode; a conditional access system, coupled to the decoder, that receives at least one device display mode, that compares the at least one device display mode and the at least one authorized display mode, and that outputs a control signal; and an output, coupled to the decoder and to the conditional access system, that outputs the content according to the control signal. - View Dependent Claims (9, 10, 11, 12, 13)
