    Abstract: A method is provided that comprises tuning a radio system to a frequency band that contains a locally-broadcast terrestrial radio signal. The locally-broadcast terrestrial radio signal comprising a main signal component and a side data component is thereby received. In response to receiving the locally-broadcast terrestrial radio signal a determination is made as to a permissible time for processing the side data component using a time slot schedule. The side data component is processed at the permissible time. A message corresponding to the side data component is outputted to an output device. In some instances, the side data component includes the message. In other instances, the method further includes searching a message lookup list using a code included in the side data component. When a stored code is found that matches the code, the message corresponding to the matching stored code is outputted.

    Abstract: A terminal and method for receiving a broadcast service by the terminal in a broadcast system are provided. The method includes performing a registration procedure for subscription and reception of the broadcast service through a Browser And Content Mobile Broadcast (BSCAST) Subscription Management (BSM) responsible for managing subscription information; receiving a Long Term Key Message (LTKM), including key information for encryption of the broadcast service, generated from the BSM; receiving a completed Short Term Key Message (STKM), the completed STKM being generated by performing Message Authentication Code (MAC) processing on a partially created STKM; receiving, from a Broadcast Service Distribution/Adaptation (BSD/A) which is responsible for transmitting the broadcast service, an encrypted broadcast service which is encrypted by a Traffic Encryption Key (TEK) for deciphering the broadcast service; and deciphering the encrypted broadcast service by the TEK obtained using the LTKM and the completed STKM.

    Abstract: One or more circuits of a satellite reception assembly may be operable to receive a satellite signal, recover content carried in the satellite signal, and broadcast a signal carrying the content for reception by one or more mobile devices. The satellite reception assembly may be mounted to the residence of a satellite subscriber. The signal carrying the content may be frequency locked to a reference signal that is available to the satellite reception assembly and to one or more other satellite reception assemblies. The reference signal may be a GNSS signal. The one or more circuits may communicate with the one or more mobile devices to provide a key to the one or more mobile devices, where the key is required for descrambling and/or decryption of the content carried in said signal.

    Abstract: The content distribution system of the invention changes over the content distribution destination between terminals which have different content receiving formats. The terminals comprise means for requesting, while viewing content from a broadcasting station, changeover of distribution of this content to another terminal. The broadcasting station comprises means for changing over the content distribution destination on the basis of the aforesaid request. The content distribution system of the invention also comprises means for deciding on the distribution format of content in accordance with the type of aforesaid other terminal, which corresponds to the destination to which content distribution is to be changed over to by the changeover means. The means for deciding on distribution format comprises for example means which distributes content by scrambled broadcast when the aforesaid other terminal is a set-top box, and which encrypts content by means of codec conversion when the other terminal is a terminal connected in a broadband environment.

    Abstract: A service information receiving apparatus (1) for receiving scrambled charged service information transmitted as being multiplexed on an FM broadcast radio wave from an FM broadcasting station (3) causes a control section (43) to perform a predetermined arithmetic operation by using a variable key as one of descramble keys affixed to the scrambled charged service information received by a service information receiving section (40) and a half-fixed key as one of descramble keys, which is stored in an IC card (2) detachably attached to a receiving apparatus main body, thereby preparing a new descramble key, which is used to descramble the received charged service information.
