CHANNEL DECODING DEVICE IN TRANSPORT STREAM PACKET, AND METHOD THEREOF |
摘要 |
A channel decoding device in a transport stream packet and a method thereof are provided to increase the efficiency of channel decoding by generating and outputting a transmission stream packet at which header information having an error is corrected after confirming whether or not an error exist in a header of the transmission stream packet. A first Reed-Solomon decoder(420) inspects an error about a transmission stream packet, and generates error notification if an error exists in the transmission stream packet. A header error corrector(430) corrects the error and generates a corrected transmission stream packet based on the error notification. A second Reed-Solomon decoder decodes the corrected transmission stream packet according to a Reed-Solomon method. A stream arranging unit(440) arranges and outputs the transmission stream packet and the corrected transmission stream packet that are transferred from the first and second Reed-Solomon decoders. |
