Digital broadcast receiving apparatus

Abstract

A digital broadcast receiving method, in which a digital broadcast signal, including layers each obtained by dividing a transmission bandwidth into a plurality of segments and combining some of the segments, is received, and images and/or sound are output from one of the layers constituting the received digital signal. The digital broadcast receiving method includes detecting a field strength and/or detecting a reproduction condition of each layer of the received digital broadcast signal, determining which layer to output based on the detected field strength and/or the detected reproduction condition, and switching the output layer to the determined layer based on a broadcasting format, for each layer, of each broadcast station.

What is claimed is:  
     
         1 . A digital broadcast receiving method, in which a digital broadcast signal, comprising layers each obtained by dividing a transmission bandwidth into a plurality of segments and combining some of the segments, is received, and images and/or sound are output from one of the layers constituting the received digital signal, said digital broadcast receiving method comprising the steps of: 
 detecting a field strength and/or detecting a reproduction condition of each layer of the received digital broadcast signal;    determining which layer to output based on the detected field strength and/or the detected reproduction condition; and    switching the output layer to the determined layer based on a broadcasting format, for each layer, of each broadcast station.    
     
     
         2 . A digital broadcast receiving method according to  claim 1 , further comprising the step of getting the broadcasting format, for each layer, of each broadcast station via a broadcast or a non-broadcast communication medium.
