  • Publication number: 20090100490
    Abstract: A method of processing data of a host in an internet protocol television (IPTV) system and the apparatus thereof are disclosed. Herein, the method includes discovering a source internet protocol (IP) address for routing between a card and servers; communicating the servers using address information, wherein the address information is used by the servers to resolve a destination IP address to which to send messages for a targeted card; and routing IP packets from the discovered source IP address to the targeted card by directing the IP packets to a media access control (MAC) address of the targeted card.

  • Patent number: 7305696
    Abstract: This invention provides technology (including apparatus, method, software, and/or data structures) to broadcast data from one or more content providers via one or more broadcast channels to one or more content recipients. This technology meets the different needs of the three major stakeholders—the content providers, the broadcasters, and the content recipients. The technology provides support for identifying the data to be broadcast, setting the broadcast schedule, getting the data inserted into the broadcast stream, extracting it from the broadcast stream at the receiver, and many ancillary activities such as compression, error correction, bandwidth management, bandwidth usage reporting, and content filtering at the receiver.

  • Publication number: 20040022278
    Abstract: A method of providing localized data includes receiving, at least one of a plurality of local broadcast sites, a broadcast stream carrying global data; and inserting, at least one of local broadcast sites, localized data associated with the one of local broadcast sites into the received broadcast stream, so as to generate a modified broadcast stream carrying the global data and the localized data at the local broadcast site. A method of providing targeted data includes receiving a broadcast including a plurality of content streams, each of the content streams carrying targeted content data having certain targeting attributes; and selecting, by a selection device, one of the content streams based on the targeting attributes and attributes of a receiving party serviced by the selection device.

  • Publication number: 20040017831
    Abstract: A system and method for processing SI data such as PSIP/PSI data in a digital TV environment are discussed. In the method for processing SI data from a plurality of input transport streams into at least one output transport stream for a digital broadcasting, SI data from the input transport streams are extracted and decoded, the decoded SI data are mapped by being reconfigured for the output transport stream, and the mapped SI data are merged and re-encoded to generate the output transport stream.
