  • Patent number: 8498312
    Abstract: Aspects of the invention provide apparatuses, computer media, and methods for supporting the broadcast of signaling data over a network. Signaling data is encoded, partitioned into M signaling segments, and distributed over M corresponding data frames. A data stream with the partitioned signaling data is transmitted through a digital terrestrial television broadcasting system, where the partitioned signaling data may include physical layer configurable data. The number of distributed signaling segments may be determined from a predetermined value or from a parameter contained in pre-signaling data. The number of physical layer pipes supported by signaling data may be increased by separating the static signaling part and the dynamic signaling part, dividing static signaling part into signaling segments, and interleaving the signaling segments over the data frames. The number of physical layer pipes can be further increased by adding at least one P2 symbol.

  • Patent number: 8218559
    Abstract: In accordance with an embodiment, a best-effort service is divided into packets for best-effort digital broadcast transmission. The packets are encapsulated with an encapsulation protocol that uses a packet order defining field. The encapsulated packets are inserted into an unused portion of a slot of a digital broadcast transmission frame. Then, the encapsulated packets are repeatedly inserted into the unused portion of the slot of the digital broadcast transmission frame in a packet-carousel fashion. And the transmission frame is digitally broadcast. In accordance with an embodiment, a digital broadcast transmission is received. Encapsulated packets that have been repeatedly broadcast in a packet-carousel fashion are accessed from a best-effort portion of a digital broadcast transmission frame slot. And a best-effort service is composed from the encapsulated packets by combining the encapsulated packets in an order based on a packet order defining field of the encapsulated packets.

  • Patent number: 7894399
    Abstract: The present invention provides methods and apparatus for a wireless system broadcasting a plurality of data packets to at least one wireless terminal. The wireless system comprises a plurality of base stations that interfaces to a backbone network in order to receive the plurality of data packets from a service source. Data packets are sent to a wireless terminal by a first base station transmitting a first channel burst and by a second base station transmitting a second channel burst, in which corresponding time offsets of the channel bursts, as characterized by amounts phase shifts, are different. Consequently, when the wireless terminal executes a handover from the first base station to the second base station, a probability that some of the data packets are lost, as result of practical network considerations, is reduced.

  • Patent number: 7877663
    Abstract: Elements of a coding table which are error-free are found at S2. At S3, corresponding elements in an erasure information table are completed, indicating that the elements in the coding array are correct. A counter is initialized at Nmax, which is the maximum number of errors that can be corrected, at S4. At S5, the row of the erasure information table is scanned beginning from the first parity column for empty elements. Each empty parity date element of the erasure information table row is marked as incorrect at S7 For each such element, the counter is decremented at S8. At S9, the elements of the erasure information table are scanned from the first column of the application data and zero padding section for empty elements. At step S11, an empty element is marked as incorrect. At step S12, the counter is then decremented. It is determined at step S13 whether or not the counter is equal to zero.

  • Patent number: 7843947
    Abstract: An improved system and method for transmitting a multiplexed service stream over an error prone DVB-H channel. Media IP packets are priority labeled. For each time slice burst, the IP packets are grouped based upon the priority labels. MPE-FEC matrices are made for the different priority labels in each time slice burst. RSDT columns are computed such that the average service bit rate does not overshoot the maximum allowed service bit rate, and the protection increases with priority. The ADT and RSDT of the MPE-FEC matrices are then encapsulated into MPE-FEC sections.

  • Patent number: 7729385
    Abstract: A packet encapsulator includes a filter module that identifies one or more carousel packets from a plurality of received packets. These one or more carousel packets are then stored in a packet buffer. The packet encapsulator also includes a channel queue for enqueuing packets for transmission across a broadcast transmission medium. For instance, the channel queue also receives the forwarding packets from the filter module. The channel queue also receives the one or more carousel packets from the packet buffer when at least a predetermined amount of available bandwidth exists in the broadcast transmission medium. The broadcast transmission medium may be a digital broadcast network such as a DVB handheld (DVB-H) network or a DVB terrestrial (DVB-T) network. Alternatively, the broadcast transmission medium may be a cable network.

  • Patent number: 7697478
    Abstract: In a digital broadcasting network, a mobile terminal receives hierarchical ESG data relating to available broadcast programs adjacent network areas. The terminal is operable whilst receiving a first program from a transmitter in a first network area for detecting a need for handover to a second network area, and for then determining from the ESG data if the same program is available in the second network area. If it is, the terminal then receives the program from a transmitter in the second network area. Otherwise, it determines one or more programs which are similar to the first program, and presents them on a display for selection by a user. This involves determining which programs have an identifier in common with the first program. The identifier can be any one or more of a program identifier, a service identifier, a channel identifier, a category identifier and a genre identifier, for example.
