摘要:
The present invention provides a method of transmitting broadcast signals. The method includes, formatting, by an input formatting block, input streams into plural PLPs(Physical Layer Pipes); encoding, by an encoder, data in the plural PLPs; time interleaving, by a time interleaver, the encoded data in the plural PLPs, wherein the time interleaving includes: cell interleaving, by a cell interleaver, the encoded data by permuting cells in a FEC(Forward Error Correction) block in the plural PLPs; frame mapping, by a framer, the time interleaved data onto at least one signal frame; and waveform modulating, by a waveform block, the mapped data in the at least one signal frame and transmitting, by the waveform block, broadcast signals having the modulated data.
摘要(中):
本发明提供了一种发送广播信号的方法。 该方法包括:通过输入格式化块将输入流格式化为多个PLP(物理层管道); 由编码器对所述多个PLP中的数据进行编码; 通过时间交织器对多个PLP中的编码数据进行时间交织,其中时间交织包括:通过信元交织器,通过置换多个PLP中的FEC(前向纠错)块中的信元来对编码数据进行信元交织; 由成帧器将时间交织数据帧映射到至少一个信号帧上; 通过波形块对所述至少一个信号帧中的映射数据进行波形调制,并通过波形块发送具有调制数据的广播信号。
