Abstract
A digital broadcasting receiver capable of receiving HD (High Definition) broadcasting, SD (Standard Definition) broadcasting and the like. In the digital broadcasting receiver, a digital broadcasting signal subjected to demodulation is separated/divided in a transport unit before being supplied to decoders. Data on a packet ID included in the digital broadcasting signal is outputted from the transport unit. An MPU determines HD broadcasting or SD broadcasting according to the data on the packet ID and when the MPU determines the SD broadcasting, it instructs the transport unit to have a set subchannel displayed and also instructs an OSD control unit to make an OSD of the subchannel.
