APPARATUS AND METHOD FOR CHANGING CHANNEL IN DIGITAL BROADCAST RECEIVER

摘要

A channel changing apparatus and method in a digital broadcast receiver are provided to reduce delay when a channel is changed. A broadcast data storage unit(106) stores a channel predicted to be changed and buffers it. A channel prediction database(116) stores and manages previous channel change information. A channel changing unit(120) detects a channel change request and controls to store the requested changed channel in the channel prediction database. When the channel changing unit detects the channel change request, a channel predicting unit(122) controls to search a change-predicted channel to be changed following the changed channel from the channel prediction database and buffers the same in the broadcast data storage unit.
