Patent ID: 8831368

Claim:
An adaptive coding modulation ACM-based simulcast transmission and reception apparatus, comprising: a transmitter configured to analyze whether or not it is raining in a region where a receiver is present on the basis of channel state information (CSI) provided by the receiver, encode and/or modulate an image signal according to the analysis result, and provide the encoded and/or modulated image signal through a single band or multiple bands, wherein the transmitter includes: an analyzer configured to analyze whether or not it is raining in the region where the receiver is present on the basis of the CSI; a generator configured to generate an image signal of which a resolution has been adjusted on the basis of an original image signal according to the analysis result of the analyzer; an encoder configured to encode and/or modulate the image signal generated by the generator according to the analysis result of the analyzer; and a transmission unit configured to provide the image signal encoded and/or modulated by the encoder through the single band or the multiple bands according to the analysis result of the analyzer.
