    Abstract: The present invention provides methods and apparatus for a wireless terminal to receive channel bursts in a wireless system while the wireless terminal is performing a handover from one base station to another base station. The wireless terminal determines that a handover may be necessary if a handover criterion is satisfied based upon a measurement of the signal quality associated with the current serving base station. If so, the wireless terminal performs measurements for the candidate cells, which are maintained in a candidate list. The wireless terminal will select one of the candidate cells (corresponding to the new serving base station) if the associated signal quality is sufficiently better than the current serving base station. After determining that a handover is necessary and before completing the handover to the new serving base station, the wireless terminal receives a last channel burst from the current serving base station.

    Abstract: Aspects of the invention provide apparatuses, computer media, and methods for supporting the broadcast of signaling data over a network. Error detection and protection as well as modulation mechanisms enhance the flexibility and robustness of signaling data for digital video broadcasting. A first error detection code for a first portion of signaling data and a second error detection code for a second portion of the signaling data are determined. The signaling data is combined with data and transmitted as a digital stream through a digital terrestrial television broadcasting system. A portion of the signaling data may include a configurable part and a dynamic part or may include different dynamic parts of the signaling data. Different portions of the signaling data may be separately modulated and encoded. A portion of the signaling data may be divided over a plurality of code words and evenly distributed over a transmission period.

    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.

    Abstract: A system and method for dynamically dividing the capacity of a fixed time division multiplexing (TDM) frame between physical channels for data transmission. According to various embodiments, a time frequency frame is divided into a plurality of subframes, and each of the plurality of subframes are divided into a plurality of corresponding slots. The plurality of slots are then selectively time shifted such that a defined time shift exists between corresponding slots in each subframe within the time frequency frame. For any slots or slot portions which have been selectively shifted beyond the end of the time frequency frame, such slots or slot portions are cyclically shifted to the beginning of the frame. Service data is then written into the slots of the time frequency frame, and the frame containing the service data can then be transmitted. Initialization and service access processes for a receiver are also provided.

    Abstract: Aspects of the invention are directed to service discovery in a digital broadcast network. A service discovery descriptor, which may be electronic service guide-provider and cell specific, provides mapping between a service identifier, a logical channel identifier, and a physical channel, which may be characterized by a frame identifier and a slot identifier, that is, each physical channel may have one or more slots within one or more frames. A neighboring service discovery descriptor provides mapping for the service available within neighboring cells. Aspects of the invention are directed to an encapsulation protocol that encapsulates variable length data, including, but not limited to, the service discovery descriptor and the neighboring service discovery descriptor, into fixed length data stream packets.

    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 initialised 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 S7For 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. When the counter becomes is equal to zero, operation proceeds to step S14 where the decoder operates to fill remaining empty elements in the erasure information row as correct. Thus, whilst the count of incorrect elements for the row has not exceeded a maximum and whilst empty elements remain, empty elements of the erasure table row are marked as incorrect beginning with parity data elements and then continuing from the application data end.
