DIGITAL BROADCASTING SYSTEM AND METHOD

摘要

The present invention relates to a digital broadcasting system and method. A digital broadcasting transmitting apparatus transmits message data using an idle band of a broadcasting channel. A terminal flickers a logo at the top of a standby screen so as to notify a recipient that the message data has been received, and displays a message on a screen when the recipient selects a shortcut key. According to the present invention, since a message can be sent without needing recipient's permission, and a message can be sent to a recipient who is not watching a broadcast program, the message can be sent according to a service provider's plan, inconvenience to the recipient when the recipient receives a message while watching the broadcast program can be reduced, and the message is stored in a storage unit of a terminal and can be rechecked. Accordingly, a service for providing information and advertisement to the recipient can be reinforced. In addition, since the message is transmitted using a broadcasting channel in which an idle band is generated, a band is not additionally allocated, thereby improving economic efficiency.
