Broadcast receiver having a function of displaying previously stored image during channel selection

摘要

A broadcast receiver retrieves from a database the image of a program on a user-selected channel which was stored previously at the same time so as to display the image on a display device, in response to a channel selection command by a user. If a broadcast exists on the user-selected channel, the broadcast receiver displays the broadcast program on the display device. If no broadcast exists on the user-selected channel, the broadcast receiver displays a message that there is no corresponding broadcast on the display device. By viewing, during the channel selection, the displayed image of the program stored previously, the user can ascertain whether or not the channel being selected is the same channel as the user desires to view. If the channel is not the desired channel, the user can provide a second channel selection command while the preceding channel selection is performed. This permits the user to select a desired channel quickly.
