Abstract
A system to transmit a set of programs from a transmitter to a receiver is used to accommodate different levels of security used for each program. When a high level of security is necessary for transmitting or receiving a program the transmitter and/or receiver is operable to accommodate that level of security. Thus, both transmitters and receivers are operable to be reconfigured to encrypt or decrypt, respectively, at different levels. Accordingly, differing amounts of programs can be transmitted or received based on the resource requirements needed at any level of security. Consequently, a high level of encryption/decryption requires more resources and allows the processing of fewer services, while a lower level of encryption/decryption allows more services to be transmitted/received.
