Abstract: An apparatus for transmitting broadcast signal according to the present invention includes an enhanced layer stream partitioner configured to generate first and second enhanced layer partitioned signals by partitioning an enhanced layer stream; first and second combiners configured to generate a first multiplexed signal corresponding to the first enhanced layer partitioned signal and a second multiplexed signal corresponding to the second enhanced layer partitioned signal; first and second power normalizers configured to reduce powers of the first multiplexed signal and the second multiplexed signal; first and second time interleavers configured to generate a first time-interleaved signal corresponding to the first enhanced layer partitioned signal and a second time-interleaved signal corresponding to the second enhanced layer partitioned signal; and first and second OFDM transmitters configured to transmit signals corresponding to the first time-interleaved signal and the second time-interleaved signal using an OFDM communication scheme.

Abstract: Disclosed herein is an integrated core network of 5G and ATSC 3.0. The integrated core network of 5G and ATSC 3.0 includes multiple control plane entities and a user plane entity, and further includes an ATSC 3.0 gateway, thereby enabling multimedia content transmitted from the ATSC 3.0 gateway to the user plane entity under the control of the control entity to be delivered to user equipment over an ATSC 3.0 terrestrial network. The ATSC 3.0 gateway may include an ATSC 3.0 Control Plane Gateway (CP-GW) connected between the user plane entity and the multiple control plane entities and an ATSC 3.0 User Plane Gateway (UP-GW) connected to the user plane entity.

Abstract: Disclosed herein are a method for transceiving a broadcast signal using a combination of multiple antenna schemes with layered division multiplexing and an apparatus for the method. A method for receiving a broadcast signal includes generating received signals based on signals that are received through multiple receiving antennas, estimating channels between the receiving antennas and transmitting antennas, restoring a core-layer signal corresponding to the received signals, and restoring an enhanced-layer signal based on a cancellation process, wherein the cancellation process corresponds to the core-layer signal and is separately performed for the individual receiving antennas.
