摘要： A receiver that receives an Orthogonal Frequency Division Multiplexing (OFDM) signal obtained by modulating a common packet sequence and data packet sequence. The common packet sequence is made up of packets common to a plurality of streams. The data packet sequence is made up of packets specific to one of the plurality of streams. The receiver sorts the common packet sequence, obtained by demodulating the received OFDM signal, in the time domain, and sorts the data packet sequence, obtained by demodulating the received OFDM signal, in the time domain. The receiver then switches the output for error correction from the one sorting over to the other sorting if, while the one sorting supplies its output to the error correction, the other sorting completes its input of a predetermined unit of information to be processed.

摘要： The present technology relates to a data readout device, a data readout method, and a program capable of preventing occurrence of a period in which no data is output. In circumstances where data is accumulated and the accumulated data is readout, the data cannot be readout and an underflow occurs if a situation occurs in which an error occurs in accumulating the data and the data cannot be accumulated. Readout is controlled using information included in data to prevent a continuous underflow despite the occurrence of an error has stopped after the underflow occurred. The accumulated data, information of which has been signaled, is started to read out at a timing specified by the information signaled in the data. The present technology is applicable to a reception device that receives a DVB-T2 signal in theM-PLP system.
