Abstract

During an operation performed to obtain time information of a previously designated channel when an XDS scanning master detects from an interrupt that a user designates his/her favorite channel via a key the master cancels the operation performed for the previously designated channel to obtain time information, and a tuner setting master shifts from the previously designated channel to the favorite channel and starts to receive a broadcast signal corresponding to the favorite channel. The XDS scanning master performs an operation to obtain time information from the broadcast signal corresponding to the favorite channel received. Whenever a favorite channel is designated, a current operation to obtain time information is canceled and a favorite channel currently designated by a user is preferentially subjected to the operation to obtain time information.

Claims10

Dependent claims

A broadcast reception device comprising:

reception means for receiving a broadcast signal;
time information acquisition means for performing an operation searching for and acquiring time information for counting a current time, said time information acquisition means including:
signal extraction means for extracting from the broadcast signal a designated broadcast signal corresponding to a designated channel;
and
search means for searching for said time information from the designated broadcast signal extracted by said signal extraction means,
wherein when a desired channel is newly selected, said time information acquisition means cancels the acquisition operation currently performed and performs a new acquisition operation with respect to said desired channel that is newly selected;
and
processing means for designating a channel unsearched by said search means for said time information and causing said time information acquisition means to perform the acquisition operation,
wherein said processing means is started when a decision to acquire time information is not indicated with respect to a search performed on said desired channel by said search means for said time information.
