Abstract:
1. A digital broadcasting receiving apparatus provided with a plurality of antennas which have directivities in different directions and each of which receives a digital broadcasting wave transmitted from outside the digital broadcasting receiving apparatus, said digital broadcasting receiving apparatus selecting at least two antennas from among said plurality of antennas to perform diversity combining, wherein said digital broadcasting receiving apparatus comprises: a plurality of switches for switching among said plurality of antennas; an antenna combination determination processing unit for determining switching of said at least two selected antennas on a basis of a state of reception of digital broadcasting waves received by said at least two selected antennas, further wherein if all of delay times included in respective delay profiles of the digital broadcasting waves received by said at least two selected antennas are equal to or longer than a predetermined time, said antenna combination determination processing unit provides an instruction for switching among said plurality of antennas for each and every of said plurality of switches, and if at least one of the delay times included in said respective delay profiles is not equal to or longer than said predetermined time, said antenna combination determination processing unit provides an instruction for switching of the antenna among said plurality of antennas which has the maximum delay time in the delay times included in said respective delay profiles; and a switch control unit for providing an instruction for switching among said plurality of switches according to the instruction from said combination determination processing unit.
