A digital broadcast receiver for receiving a digital broadcast, in which a plurality of digital broadcast signals are multiplexed in a receive frequency and information as to, at least, the type of broadcast content of each of said digital broadcast signals, as additional information, is transmitted together with said digital broadcast signals, comprising: frequency specifying means (34-36) for specifying a receive frequency; content type specifying means (37, 38) for specifying the type of broadcast content; and control means (43) for controlling signal reception with a receive frequency specified by said frequency specifying means (34-36) and controlling such that a digital broadcast signal with the broadcast content specified by said content type specifying means (37, 38) is identified among and selected from a plurality of digital broadcast signals received at the specified receive frequency, wherein said control means (43), when a changed receive frequency is specified, controls the signal reception with the new receive frequency, and in the case where a broadcast content had been specified by said content type specifying means (37, 38) before the receive frequency was changed, controls such that a digital broadcast signal with the broadcast content specified by said content kind specifying means (37, 38) is selected from a plurality of digital broadcast signals received at the new receive frequency.
Claim 2
Dependent Claim
126 words
A digital broadcast receiver according to claim 1, wherein said control means (43), when a changed receive frequency is specified, controls the signal reception with the new receive frequency, and in the case where a broadcast content had been specified by said content type specifying means (37, 38) before the receive frequency was changed, controls such that, if a digital broadcast signal with the broadcast content specified by said content kind specifying means (37, 38) is present in a plurality of digital broadcast signals received at the new receive frequency, the digital broadcast signal is selected, and if a digital broadcast signal with the broadcast content specified by said content kind specifying means (37, 38) is not present therein, any channel selecting operation is not performed.
Claim 3
Dependent Claim
84 words
A digital broadcast receiver according to claims 1 or 2, further comprising a display means (45) for displaying, when a changed receive frequency has been specified by said frequency specifying means (33-35) and signal reception with the new receive frequency has been performed, channels for digital broadcast signals correspondent to a broadcast content specified by said content type specifying means (37, 38) before the receive frequency has been changed and selected from a plurality of digital broadcast signals received at the new receive frequency.
Claim 4
Dependent Claim
130 words
A digital broadcast receiver according to any of claims 1 to 3, wherein said control means (43) is adapted, when a digital broadcast signal corresponding to the broadcast content specified by said content type specifying means (37, 38) among a plurality of digital broadcast signals received through signal reception with the receive frequency specified by said frequency specifying means (34-36) is selected and, then, if the broadcast content of the received digital broadcast signal becomes not correspondent to the program content specified by said content type specifying means (37, 38), to control such that the channel selection is changed to another digital broadcast signal which is correspondent to the broadcast content specified by said content type specifying means (37, 38) and present in said plurality of received digital broadcast signals.
