Abstract: Provided are an apparatus and a method for processing conditional access system (CAS)-based content. A method of operating a broadcast receiving apparatus includes: receiving a broadcast stream that includes content encrypted based on a CAS; extracting, from the received broadcast stream, CAS information for decrypting the encrypted content; receiving an entitlement control message (ECM) having a preset format based on the CAS information generated in a different format for each broadcasting business operator; and displaying the content decrypted based on the ECM.

Abstract: Methods and systems for enabling a first device to present a user interface on a second device are described. The first and second devices are able to communicate via a network. A change is detected in an operational state of the first device. Responsive to the detected change, a message is sent from the first device. The message identifies computer readable instructions stored on the first device. The message is received at second device and, responsive to the receiving, the computer readable instructions are retrieved from the first device. The second device then uses the computer readable instructions whereby to present a user interface at the second device, at least a part of the user interface being determined by the computer readable instructions retrieved from the first device.
