  • Publication number: 20100142438
    Abstract: Systems and methodologies are described that facilitate broadcasting and receiving messages in a wireless media broadcast network. Mobile devices are equipped to receive media over a broadcast network where presentation of the data can be enabled through a content policy. Broadcast messages can be provisioned and delivered over the network such that mobile devices can receive the message regardless of the level or existence of purchased content. The messages can be broadcast for multiple purposes, including emergency messages, which can come from an emergency or amber alert system, venue and/or location specific messages, etc. The messages can be broadcast at a regional level as well by leveraging such functionality of the media broadcast network.

  • Publication number: 20090187593
    Abstract: Apparatus, methods and computer program products are provided for targeted media content acquisition on a wireless device. The wireless device selects media content to receive based on a resident user profile, locally constructed based on passive user data, active user data and user inference data drawn from the passive and active user data. Additionally, aspects provide for grouping of the media content prior to distribution, including communicating groups of related data in unison to limit the number of times that a wireless device needs to tune-in and/or wake-up to receive the media content, thereby reducing power consumption.
