Patent ID: 8799739

Claim:
A receiving apparatus comprising: an LDPC decoding device configured such that when an LDPC-coded data signal, LDPC representing Low Density Parity Check, and an LDPC-coded transmission control signal are transmitted in multiplexed fashion, said LDPC decoding device can decode both the data signal and the transmission control signal; a holding device configured to be located upstream of said LDPC decoding device and to hold at least said transmission control signal upon receipt of said data signal and said transmission control signal; and a control device configured to control said LDPC decoding device to decode said data signal while said transmission control signal is being accumulated in said holding device and to interrupt the current decoding so as to control said LDPC decoding device to decode said transmission control signal when said transmission control signal has been accumulated in said holding device, wherein when a physical layer pipe and a common physical layer pipe within a frame of said data signal are subject to LDPC decoding, an interruption is made and said transmission control signal of said frame is LDPC-decoded, and when the LDPC decoding of said transmission control signal of said frame is terminated, the LDPC decoding of said physical layer pipe is resumed, and at the end of the LDPC decoding of said physical layer pipe, the LDPC decoding of said common physical layer pipe in said frame is resumed.
