    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: A rate matching apparatus is capable of improving the bit error rate characteristic at a data receiving end. A rate matching part (106), which serves as a rate matching apparatus, generates, from a first encoded block corresponding to N symbols (where N is an integer equal to or greater than one), a second encoded block corresponding to N+K symbols (where K is an integer equal to or greater than one). In the rate matching part (106), a to-be-divided bit-group extracting part (122) extracts, from the first encoded block, a first bit group corresponding to any of the N symbols. A dividing part (124) divides the extracted first bit group into L divided bit groups corresponding to L symbols (where L is an integer equal to or greater than two but equal to or smaller than K+1), thereby providing the second encoded block.

    Abstract: The invention discloses a method for detecting priority of data frames comprising the steps of extracting (S1) a bit pattern from a predetermined position in a frame, comparing (S2, S3) said extracted bit pattern with a search pattern, and identifying (S4) said received frame as a priority frame in case said extracted bit pattern (BP) matches with said first search pattern (SP). By this method, the priority of a data frame can easily be detected. The invention also proposes a corresponding device for detecting priority of data frames.

    Abstract: An original data stream is encoded into a high priority data stream and a low priority data stream. The high priority data stream is encoded so as to permit decoding of the high priority data steam independently of the low priority data stream. The high priority data stream is transmitted twice, while the low priority data claim 25. is transmitted in two portions, but only once. If both the first portion and the second portion of the low priority data stream are received, and at least one complete transmission of the high priority data stream is received, then the two data streams are combined to produce a signal output of high quality. However, if any portions of the low priority data stream is lost then the low priority data stream is not used, and only the high priority data stream is used to produce output. Overall throughput is greater than would be achieved if the original data stream were transmitted with complete redundancy.

    Abstract: A communication quality is improved or signal processing is simplified in a multi-carrier communication system such as OFDM. Information different in communication quality such as systematic bits and parity bits of turbo encoded code words is combined together, and information that requires a high communication quality such as the systematic bits is mapped to carriers having a frequency close to the carriers in which the pilot signal exists used as a reference phase of demodulation than the information such as the parity bits which does not require the high communication quality such as the systematic bits.

    Abstract: A method is provided for accommodating periodic interfering signals in a wireless network. In this method, a network scans a transmission medium to locate any interfering signals. If it finds interfering signals, the scan determines their period, and the network alters the period of its superframes such that: either the period of the superframes is equal to the period of the interfering signals; the period of the superframes is an integer multiple of the period of the interfering signals; or the period of the interfering signals is an integer multiple of the period of the superframes. The network then alters the position of the superframes relative to the position of the interfering signals to arrange things such that no portion of the interfering signal interferes with a superframe beacon, such that that a maximum amount of contiguous channel time is provided in each superframe, or both.

    Abstract: A method of detecting the format of received information by detecting the format of a guiding channel of a communication system. With the use of a lookup table or other mapping technique, the detected guiding channel format is used to determine the format of the other channels of the communication system. Therefore, the format of received information can be determined without the use of TFCI information.
