A method and/or apparatus are provided for protecting control information during broadcasts in a system where primary and second mobile broadcast control messages (PMBCM and SMBCM) are utilized. In order to protect the SMBCM, a first hash information instance is computed based on hashes for each a plurality of control data blocks for the SMBCM. The first hash information instance is appended to the PMBCM. Error-correcting code words are generated for the plurality of hashes for the plurality of control data blocks for the SMBCM. These error-correcting code words are appended to the control data blocks of the SMBCM. A receiver uses the first hash instance information in the PMBCM to determine if any control data blocks of the SMBCM are corrupt. If so, the error-correcting code words may be used to reconstruct the corrupted hash(es) for the control data block(s) in order to authenticate the remaining control data blocks.

This invention provides systems and methods for providing multiple user support for shared user equipment in fantasy sports contest applications. A fantasy sports contest application may allow users to setup unique user accounts, in which user specific information such as, for example, identification information, fantasy sports contest participation information, user preference information, or any other suitable information associated with the user, may be stored. The application may personalize fantasy sports contest information and displays for the user. Local fantasy sports leagues may be created for users of common user equipment so that they may compete against each other.

Systems and methods are presented for presenting advertisements to users of a fantasy sports contest application. Advertisements are displayed in conjunction with fantasy sports contest information and may be interactive in nature. The advertisements may be used to inform the user of prizes being awarded for performance in the fantasy sports contest, including prizes being awarded for performing in an instant scoring opportunity based on real-time action in a related sports broadcast. The advertisements may be intelligently scheduled around certain events in a related sports broadcast to take advantage of user purchasing habits. The advertisements may be selected according to a user profile. The user profile may include information on the user's demonstrated interests, which may be determined using the user's preferences in the fantasy contest, prior television viewing habits, and other suitable information. The advertisements may be targeted to the user's specific geographic location. The advertisements may also be used to inform a user of an awarded prize, and to enable the user to claim the awarded prize.
摘要:
In an embodiment, a server determines to update at least one group session key (GSK) parameter for a given multicast group, the at least one GSK parameter configured to permit encryption, decryption and/or authentication of multicast messaging exchanged between members of the given multicast group during a multicast communication session. The server sends a notification to a plurality of multicast group members of the given multicast group that an update of the at least one GSK parameter for the given multicast group is available. At least one of the multicast group members receives the notification and sends a provisioning request to retrieve the updated at least one GSK parameter, the provisioning request including information specific to the given multicast group member. The server generates and encrypts the updated at least one GSK parameter and sends the encrypted at least one GSK parameter to the at least one multicast group member.
