    摘要： A receiver for receiving data in a broadcast system includes a broadcast receiver that receives, via the broadcast system, a receiver input data stream including plural channel symbols represented by constellation points in a constellation diagram. A demodulator demodulates the channel symbols into codewords and a decoder decodes the codewords into output data words. A broadband receiver obtains redundancy data via a broadband system, the redundancy data for a channel symbol including one or more least robust bits of the channel symbol or a constellation subset identifier indicating a subset of constellation points including the constellation point representing the channel symbol. The demodulator and/or the decoder is configured to use the redundancy data to demodulate the respective channel symbol and to decode the respective codeword, respectively.

    摘要： A method of operating a mobile receiving system includes the steps of registering and storing, in a first cycle, a plurality of receivable transmitters in a first specifiable frequency range with a first receiving method, and establishing a number of the receivable transmitters from the first cycle. The method further includes the steps of registering and storing, in a second cycle, a plurality of receivable transmitters in the first specifiable frequency range with the first receiving method, and establishing a number of the receivable transmitters from the second cycle. The number of receivable transmitters from the first cycle are compared with the number of receivable transmitters from the second cycle and, when the numbers of receivable transmitters in the first cycle and the second cycle deviate from one another by a first specifiable value, the first receiving method is switched to a second receiving method.

    摘要： An apparatus and method are provided. The apparatus comprises a plurality of inputs, a plurality of receive buffers, a processor and an output. The plurality of inputs are configured to receive a plurality of data streams. Each data stream comprising a respective plurality of data blocks carrying common content. The plurality of receive buffers are each configured to store the data blocks of a respective on of the plurality of data streams including storing quality information associated with each data block. The processor is configured to select stored data blocks from the respective buffers to form an output data stream carrying the common content. The processor is further configured to carry out signal processing on the selected data blocks in dependence on the associated quality information. The output is configured to output the selected and error concealed data blocks. The quality information associated with each data block corresponds to a quality experienced by a receive path at the time of reception of each data block.
