  • Patent number: 8325281
    Abstract: Systems and methods are provided for receivers of digital broadband broadcast signals to determine a time of delivery and a version of a particular signaling table. The receiver is able to determine whether an update of the signaling table is needed based on factors such as whether the update applies (e.g., a DVB-H specific change for a mobile terminal in a DVB-H network). The receiver may power down while awaiting delivery of the signaling table (or utilize the radio for other purposes), powering back up in time to receive the signaling table.

  • Patent number: 8155115
    Abstract: A method for transmission, a method for reception, a system, a transmitter and a receiver for signalling a hierarchical priority mapping of a transport stream (TS) to a receiver is disclosed. A way to separate tuning information between different TSs with different priorities. In a wireless hierarchical broadband transmission, preferably based on DVB-T, one signal may carry two transport streams: low priority (LP) stream and high priority (HP) stream, and both should be identified with their own respective transport_stream_id. One bit flag is added into a certain descriptor of the broadband transmission to indicate the hierarchy of the transport stream on which said descriptor is providing information. By the appliance of this priority indication or priority flag, the receiver can obtain hierarchy mapping of each transport stream announced in the administrative information of the broadband transmission.

  • Patent number: 7567806
    Abstract: A digital video broadcast network comprises a content provider and several transmitters. Each transmitter may transmit more than one signal, different signals having different frequencies, multiplexes and the like and relating to different network types. An integrated receiver/decoder (IRD) is mobile in the area around the transmitters. As well as transmitting service information as part of a network information table on a data layer, the transmitters provide in their output signals transmitter parameter information as TPS data on a physical layer. This TPS information includes information identifying whether there are other networks available, and preferably the number of other networks. Transmission parameters relating to the other networks are included in an other_network_descriptor, forming part of an NIT actual or a BAT, or alternatively in an NIT_other. This information is used by the IRD in signal scan.

  • Publication number: 20070002723
    Abstract: Methods and system for transmitting a DVB-H network ID in transmission parameter signaling (TPS) data are described. A sixteen bit DVB-H network ID may be divided into four four-bit portions, and each four-bit portion may be included in an orthogonal frequency division multiplex (OFDM) TPS frame transmitted by the DVB-H network. Because each OFDM TPS frame also includes a frame order of that frame within its corresponding super-frame, a receiver of the TPS data can reassemble the network ID by ordering the four received portions according to the frame order of the respective OFDM TPS frames in which they were received. The sixteen bit DVB-H network ID may alternatively be divided into two eight-bit portions, and each eight-bit portion may be included in the cell_ID bits of two frames of a super-frame.
