Abstract:
Disclosed are a digital broadcast reception device, a digital broadcast reception method and a program that shorten the period during which display is not possible that occurs when channels are switched. The digital broadcast reception device (100) is provided with a data acquisition unit (111) that measures data related to the data reception waiting that occurs in channel switch processing, a channel switch-directing unit (110) that controls the timing of operation of the data acquisition unit (111), a parameter-generating unit (112) that generates control parameters based on the data acquired by the data acquisition unit (111), a processing time-calculating unit (113) that calculates the channel switching time based on the control parameters generated by the parameter-generating unit (112), and a channel switch-timing control unit (114); that controls the timing for starting channel switching to shorten the data reception wait time that occurs during channel switching based on the channel switching time calculated by the processing time-calculating unit (113).
