Digital broadcasting transmit system

As with available conventional compatible with the broadcast system of the digital broadcasting transmission system that can transmit a separate additional data, after generating the parity bits by encoding the information bit of the additional data by transmitting with the information bits, the ghost signal of the channel and even in a noisy channel it can be more reliably transmit the MPEG video / audio data and additional data. In particular, it is possible to greatly improve the operational performance of the predictor in the slicer, and a trellis decoder, the received system. Additional data, convolutional encoder
