    摘要： A method and an apparatus for encoding, transmitting, and receiving signaling information in a broadcasting/communication system are provided. The method includes generating the signaling information which comprises a plurality of pieces; determining a number of coded blocks to which the signaling information is to be encoded, based on a number of bits of the signaling information and a number of encoder input information bit; segmenting each piece of the signaling information based on the number of the coded blocks; constructing input information bits of each coded block to include segmented parts of each piece of the signaling information; encoding the input information bits to each coded block; and transmitting each coded block.

    摘要： Methods and apparatus are provided for transmitting and receiving a data stream in a digital video broadcast system. The data stream is segmented into a plurality of segments of the data stream. A frame is generated. The frame includes a preamble section and a data section. The data section carries the data stream, and the preamble section carries signalling information. The frame is transmitted to a receiver. In generating the frame, the data section of the frame is segmented into a plurality of frequency zones, and at least one segment of the data stream is mapped to a frequency zone of the plurality of frequency zones. The signalling information includes first segmentation information of the data stream and second segmentation information of the plurality of frequency zones.

    摘要： A method and apparatus for transmitting data are provided. In the method, data streams are mapped onto frames, a word is generated including information for receiving the data streams for a given frame, and parity bits are derived from the word for the given frame. The data is arranged in the frames. Each of the frames includes a preamble and a data section. The preamble and the data section are time-multiplexed. The data section includes at least a part of the data streams, and the preamble includes signaling information. The word is inserted in a preamble section of the given frame, and one of the parity bits is inserted in a preamble section of a prior frame preceding the given frame. A part of the word for the given frame is inserted within a data section of an earlier frame preceding the prior frame. The frames are then transmitted.

    摘要： A method and apparatus for transmitting a plurality of data streams in a wireless broadcast system are provided. The method includes mapping the plurality of data streams onto a super-frame that includes a plurality of frames; inserting signalling information in a first signalling information field for assisting in the reception of a first number of said plurality of data streams for a given frame, the first number being less than or equal to a limit applicable to each of the plurality of frames; dependent on a number of data streams for the given frame being greater than the limit, inserting signalling information in a second signalling information field; inserting said first and second signalling information fields in a preamble section of said given frame; and transmitting the plurality of frames.
