Description

Channel selector and channel selection method {APPARATUS AND METHOD FOR SELECTING CHANNEL}

The present invention relates to a channel selection device, and more particularly, to a channel selection device for providing a channel search screen to a viewer.

Digital broadcasts can provide viewers with more channels than analog broadcasts because they use digitized broadcast signals. The viewer selects one broadcast channel among many broadcast channels and watches a broadcast program provided on the selected channel. When the viewer is watching a broadcast program and becomes uninterested in the broadcast program or is curious about a broadcast program that is broadcast on another channel, the viewer searches for the channel by raising or lowering the channel based on the current broadcast channel. Viewers can find a broadcast program they want to watch during the channel search process.

However, in digital broadcasting, a receiver must receive a broadcast signal corresponding to one frame from a headend to provide a broadcast program to a viewer. Therefore, channel switching time in digital broadcasting is longer than channel switching time in analog broadcasting. In order to facilitate viewers' channel searching while avoiding lengthy channel searching time due to channel switching time, the headend may provide an EPG (Electronic Program Guide) to the receiver in digital broadcasting.

An EPG provides a viewer with information related to a broadcast program through an additional channel, and includes a mosaic EPG, a text EPG, and the like.
