Abstract: A system for securely communicating callback signals to a head end includes a callback server and a user device communicating a request to open a callback session to the callback server. The callback server opens a first session between the callback server and a user device. The user device communicates an encrypted callback data signal to the callback server through the first session. The callback server opens a second session between the callback sever and a conditional access system associated with a head end, verifies the callback data signal at callback server, and communicates the encrypted callback data signal to the conditional access system through the second session. The conditional access system decrypts the encrypted callback data signal to form decrypted callback data.

Abstract: A method and system for generating local channels includes a user receiving device and a local headend in communication with the user receiving device generating a local channel using a multicast stream, generating local channel guide data comprising tuning data for the local channel and communicating a control command to a user receiving device. The control command comprises tuning data for the local channel. The user receiving device stores tuning data for the local channel with program guide data stored in the user receiving device in response to the control command.

Abstract: A system and method of switching services in a receiver unit includes a verifier module in the receiver unit receiving a service signal and middleware within the receiving unit receiving an evaluate signal and enabling the verifier to determine a service change from the service signal. The middleware changing a service flag for the service when a service change is determined at the verifier.

Abstract: A system and method for controlling a receiving unit to switch services includes a network operation center communicating a service signal to the receiving unit and an evaluate signal to the receiving unit. The receiving unit changes a service of the receiving unit in response to the evaluate signal.
