    摘要: A method, a system, a transmitter and a receiver for identification of a time sliced elementary streams using PSI/SI tables. This identification provides a way to separate time-sliced elementary stream from non-time-sliced elementary streams by defining two descriptors in PSI/SI tables. A time slice identifier descriptor is defined, which can be used to identify elementary streams which are time sliced. This descriptor is also used to provide additional information about the transmitted elementary streams. The invention provides a way to announce additional information of the time sliced elementary streams via PSI/SI tables. Additionally, it provides a mechanism to categorize single elementary stream(s) as non-time sliced and time sliced. A way to identify time sliced elementary streams carried over DVB networks is disclosed and providing additional information on those streams. This can be done by using the time slice identifier descriptor. The descriptor can be used at least in Network Information Table (NIT), Program Map Table (PMT) and IP/MAC Notification Table (INT) tables. Time slicing provides a way to save power in the receiver in broadband transmission.

    摘要: 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.

    摘要: Provided are apparatuses and methods for padding a series of real-time service time-slice bursts with related non-real-time service data in a digital broadcast transmission system. Real-time services (e.g., streaming video) are formed into a series of bursts or slots as a single frame. Available capacity within each slot of the frame is filled using related non-real-time service data (e.g., a file download). Receivers may receive individual bursts from within the frame and/or may receive the entire frame in order to receive the related non-real-time service data.

    摘要: 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. 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.

    摘要: A multiprotocol encapsulation forward error correction (MPE-FEC) frame comprising datagrams and FEC data is shown wherein an MPE encapsulator places datagrams in MPE sections and FEC data in MPE-FEC sections. A time slicing block forms a sequence of bursts and dividing the MPE-FEC frame between bursts, such that MPE sections are sent in at least two bursts. The time slicing block adds a burst number parameter to headers of the MPE and MPE-FEC sections to enable a terminal to determine whether to expect further bursts carrying data from the MPE-FEC frame.

    摘要: 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.
