RECEPTION DEVICE, SOUND REPRODUCING METHOD, SOUND REPRODUCING PROGRAM, AND RECORDING MEDIUM THEREOF

摘要

PROBLEM TO BE SOLVED: To suppress the occurrence of incongruity with reproduced sound when switching a reproduced broadcast between broadcasts of simultaneous broadcasting wherein identical programs are broadcast in the same time period.

SOLUTION: In a period when an evaluation value of reception quality is equal to or higher than a first threshold, sound channel data based on an H broadcast is selected as selected sound data; and in a period when the evaluation value is lower than the first threshold, sound channel data based on an L broadcast is selected as selected sound data. A control unit 190 generates an attenuation control signal MXS which designates distribution amounts of selected sound data PBTCto PBTLFEto respective speakers, on the basis of the evaluation of reception quality etc. Subsequently, the control unit 190 issues the attenuation control signal MXS to a sound signal mixing unit 223. The sound signal mixing unit 223 generates output sound data ADTCto ADTLFEdesignated by the attenuation control signal MXS and outputs them to sound output units 130Cto 130SW.
