System and method for DRM regional and timezone key management
First Claim
1. A cryptographic media stream system for ensuring media stream content is only consumed in authorized regions, the system comprising:
- at least one encryption/decryption key source configured to provide at least one of a regional key and a timezone key, wherein the regional key and the timezone key are globally unique keys;
a media encryption engine that receives an unencrypted media stream and encrypts the encrypted media stream; and
a media decryption engine that receives the encrypted media stream, and decrypts the encrypted media stream in response to at least one of the regional key and the timezone key.

22. A system for distribution, reception and display of media streams and for ensuring media stream content is only consumed in authorized regions, the system comprising:
-
a source for information regarding a subscriber for authentication;
at least one encryption/decryption key source configured to provide at least one of a regional key and a timezone key, wherein the regional key and the timezone key are globally unique keys;
a media encryption engine that receives an unencrypted media stream and encrypts the encrypted media stream; and
a media decryption engine that receives the encrypted media stream, and decrypts the encrypted media stream in response to at least one of the regional key and the timezone key, and validates the location of the subscriber for region and timezone using credentials.
