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.

Abstract: Provided is photochromic glass. The photochromic glass includes a photochromic layer having visible-light transmittance decreased at short-wavelength light and having visible-light transmittance increased at long-wavelength light, a short-wavelength transmission layer provided on a surface of the photochromic layer to transmit only the short-wavelength light among lights entering the photochromic layer, and a wavelength conversion layer provided on another surface of the photochromic layer opposite to the surface to convert a wavelength of light entering the photochromic layer into a long wavelength, or a long-wavelength transmission layer transmitting only the long-wavelength among lights entering the photochromic layer. The visible-light transmittance of the photochromic layer may adjust on both surfaces of the photochromic layer through the incident direction of light. It is possible to implement various colors according to the photochromic layer and further provide a heat insulation function due to the blocking of an infrared ray of the short-wavelength transmission layer.

Abstract: The present invention relates to a method and apparatus for setting a reference picture index of a temporal merging candidate. An inter-picture prediction method using a temporal merging candidate can include the steps of: determining a reference picture index for a current block; and inducing a temporal merging candidate block of the current block and calculating a temporal merging candidate from the temporal merging candidate block, wherein the reference picture index of the temporal merging candidate can be calculated regardless of whether a block other than the current block is decoded. Accordingly, a video processing speed can be increased and video processing complexity can be reduced.
