    • A digital broadcasting transmission and reception system includes a digital broadcasting transmission apparatus and a digital broadcasting reception apparatus. The digital broadcasting transmission apparatus that includes a robust processor that codes a robust stream of a dual transport stream where a normal stream and the robust stream are combined. The robust processor includes a demultiplexer (DE-MUX) that separates the normal stream and the robust stream from the dual transport stream; a robust encoder that appends a parity to the separated robust stream; a robust interleaver that interleaves the robust stream having the appended parity; and a MUX that combines the interleaved robust stream and the separated normal stream. The digital broadcasting reception apparatus includes a robust decoder that decodes a robust stream of a dual transport stream where a normal stream and the robust stream are combined. The robust decoder includes a first decoder that trellis-decodes the robust stream; a robust deinterleaver that interleaves the trellis-decoded robust stream; a second decoder that convolution decodes the deinterleaved robust stream; a robust interleaver that interleaves the convolution-decoded robust stream; and a frame formatter that adds decoded data of the second decoder to a part that corresponds to a position of the robust stream of a frame where the normal stream and the robust stream are mixed. Accordingly, a receiver of a simple structure can be provided.
    • 数字广播发送和接收系统包括数字广播发送装置和数字广播接收装置。 数字广播传输设备包括鲁棒处理器,其编码双传输流的鲁棒流,其中组合正常流和鲁棒流。 鲁棒处理器包括从双传输流分离正常流和鲁棒流的解复用器(DE-MUX); 一个鲁棒的编码器,将奇偶校验附加到分离的鲁棒流; 鲁棒交织器,其交织具有附加奇偶校验的鲁棒流; 以及组合交织的鲁棒流和分离的正常流的MUX。 数字广播接收装置包括鲁棒解码器,其解码双传输流的鲁棒流,其中组合正常流和鲁棒流。 鲁棒解码器包括对鲁棒流进行网格解码的第一解码器; 一个鲁棒的解交织器,用于交织网格解码的鲁棒流; 第二解码器,其卷积解码解交织的鲁棒流; 鲁棒的交织器,其交织卷积解码的鲁棒流; 以及帧格式化器,其将第二解码器的解码数据添加到与正常流和鲁棒流混合的帧的鲁棒流的位置相对应的部分。 因此,可以提供简单结构的接收器。
