Apparatus and method for providing secondary broadcast service in digital broadcasting system
First Claim
1. A digital broadcasting system employing a control channel and a plurality of broadcast channels, wherein the control channel is provided for transmitting therethrough a synchronous signal section and a data transmission section alternately, the system comprising:
- a transmitter for transmitting summary information and control data of the plurality of broadcast channels through the control channel while allocating the summary information and the control data to the data transmission section, and transmitting a secondary broadcast corresponding to the summary information while allocating the summary information to at least one of the plurality of broadcast channels; and
a receiver for receiving a signal transmitted through the control channel, displaying the summary information retrieved from the data transmission section, and receiving a broadcast channel through which the secondary broadcast corresponding to the summary information is transmitted when there is a request to receive the secondary broadcast.

Abstract
An apparatus and method for providing secondary broadcast services in a digital broadcasting system including a transmitter and a receiver. The transmitter transmits summary information and control data of broadcast channels through a control channel while allocating the summary information and the control data to a data transmission section, and transmits a secondary broadcast corresponding to the summary information while allocating the summary information to at least one of a plurality of broadcast channels. The receiver receives a signal transmitted through the control channel, displays the summary information after retrieving the summary information from the data transmission section, and receives a broadcast channel through which the secondary broadcast corresponding to the summary information is transmitted when there is a request to receive the secondary broadcast.
