<P>PROBLEM TO BE SOLVED: To achieve a digital broadcast-receiving apparatus in which data output does not break off when a channel is changed, and a user does not feel incongruity. <P>SOLUTION: In parallel to data receiving by a main tuner 2, channels other than a channel being received by the main tuner 2 are changed one by one, channel data is received by a sub-tuner 3, and then the data received by the sub-tuner 3 is memorized by a broadcast data memory unit 10 for each channel. When the channel received by the main tuner 2 is changed to another channel, an image is displayed in a display unit 12 using memory data memorized in the broadcast memory unit 10 until data of a new channel are received by the main tuner 2 and the received data of the new channel is decoded by a decoding unit 6. By the way, data output does not break off at a time of channel change, and the user does not feel incongruity. <P>COPYRIGHT: (C)2010,JPO&INPIT |
