Document Type and Number:
WIPO Patent Application WO/2018/048262
Kind Code:
A1
Abstract:
Disclosed are a device and a method for generating a broadcast signal frame corresponding to a time interleaver supporting multiple operation modes. The device for generating a broadcast signal frame, according to one embodiment of the present invention, comprises: a combiner for generating a multiplexed signal by combining a core layer signal and an enhanced layer signal; a power normalizer for lowering the power of the multiplexed signal to a power corresponding to that of the core layer signal; a time interleaver for generating a time-interleaved signal by performing interleaving that applies to both the core layer signal and the enhanced layer signal; and a frame builder for generating a broadcast signal frame including a preamble for signaling time-interleaver information corresponding to the time interleaver, wherein the preamble includes a field indicating starting positions of first complete FEC blocks corresponding to respective physical layer pipes.
