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 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 broadcast signal transmission method for signaling a transmission structure based on a combination of LDM technology and MIMO technology and an apparatus using the same. The broadcast signal transmission method may include generating first signaling information, indicating a transmission structure based on a combination of Multiple-Input Multiple-Output (MIMO) technology and Layered Division Multiplexing (LDM) technology, for a first subframe of a current broadcast signal frame, generating second signaling information, indicating a transmission structure based on a combination of the MIMO technology and the LDM technology, for a current subframe subsequent to the first subframe, and generating a broadcast signal using the first signaling information and the second signaling information.
