Abstract: Disclosed herein are a content provision method and apparatus using a convergence network. The content provision method may include creating a Quick UDP Internet Connections V1 (QUICV1) path with User Equipment (UE) through a Fifth-Generation (5G) core, when content satisfies a preset condition while the content is being provided to the UE through the QUICV1 path, determining to offload the content through the 5G core, creating an Internet Protocol Security (IPSEC) tunnel with an Advanced Television Systems Committee (ATSC) gateway (GW) through the 5G core, generating a QUIC multicast stream, providing QUIC multicast session information to multiple UE devices, and providing the content to multiple UE devices, for which a mode switches from a QUICV1 mode to a QUIC multicast mode, through the ATSC GW.

Abstract: Disclosed herein are a broadcast signal transmission/reception method using multiple antennas and layered-division multiplexing and an apparatus for the same. A broadcast signal transmission apparatus includes a Multiple-Input Multiple-Output (MIMO) Bit-Interleaved Coded Modulation (BICM) unit for dividing enhanced layer data into two enhanced layer signals having different polarizations, a combination unit for generating a multiplexed signal corresponding to a first transmitting antenna by combining a core layer signal corresponding to core layer data with a first enhanced layer signal, and transmission signal generation units for generating a first transmission signal, corresponding to the multiplexed signal and transmitted through the first transmitting antenna, and a second transmission signal, corresponding to a second enhanced layer signal and transmitted through a second transmitting antenna.

Abstract: Disclosed herein are a method for transmitting a broadcast signal for signaling information about a combination of Layered-Division Multiplexing (LDM) technology and Multiple-Input Multiple-Output (MIMO) technology and an apparatus using the method. The method includes generating first signaling information indicating whether MIMO technology is applied to an enhanced layer by LDM technology, generating second signaling information indicating an MIMO application method when the MIMO technology is applied to the enhanced layer, and generating a broadcast signal using the first signaling information and the second signaling information.

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.
