ENCRYPTION SYSTEM FOR SATELLITE DELIVERED TELEVISION |
摘要 |
A television content delivery system consistent with certain embodiments has a receiver system that receives television content from a plurality of content suppliers. A selective multiple encrypter selectively multiple encrypts the television content, wherein the resultant selectively multiple encrypted content stream is encrypted under at least one conditional access system (CAS) and at least one digital rights management system (DRMS). A transmitter transmits the selectively multiple encrypted television content stream to multiple receivers, so that the selectively multiple encrypted television content stream can be decrypted under either a system using at least one CAS or at least one DRMS.
