Abstract
Apparatus and method for transmitting and receiving a frame including control information in a broadcasting system. A frame for a broadcast service is generated using an in-band signaling scheme, and includes location information of control information in a next frame and indication information indicating a change/no-change in the control information in the next frame. The new frame structure minimizes power consumption of a receiver supporting the broadcast service.
Claims44
A method for transmitting a frame including control information in a system supporting a broadcast service, the system including a frame generator and a frame transmitter, the method comprising:
- generating, by the frame generator, a frame including at least one Physical Layer Pipe (PLP) and indication information for indicating a change/no-change of the control information for the broadcast service in a next frame, the indication information being included in one of the at least one PLP;
- and
- transmitting, by the frame transmitter, the generated frame.
An apparatus for transmitting a frame including control information in a system supporting a broadcast service, the apparatus comprising:
- a frame generator for generating a frame including at least one Physical Layer Pipe (PLP);
- and
- a transmission unit for transmitting the generated frame,
- wherein one of the at least one PLP includes indication information for indicating a change/no-change of the control information for the broadcast service in a next frame.
A method for receiving a frame including control information in a system supporting a broadcast service, the system including a receiver and a signal extractor, the method comprising:
- receiving, by the receiver, a frame including at least one Physical Layer Pipe (PLP) and indication information for indicating a change/no-change of the control information for the broadcast service in a next frame, the indication information being included in one of the at least one PLP;
- extracting, by the signal extractor, the indication information;
- and
- determining whether to receive control information in the next frame or to receive data information without receiving the control information in the next frame, based on the extracted indication information.
An apparatus for receiving a frame including control information in a system supporting a broadcast service, the apparatus comprising:
- a receiving unit for receiving a frame including at least one Physical Layer Pipe (PLP) and indication information indicating a change/no-change of control information for the broadcast service in a next frame, the indication information being included in one of the at least one PLP;
- an in-band signaling signal extractor for extracting the indication information;
- and
- a controller for determining whether to receive the control information in the next frame or to receive data information without receiving the control information based on the extracted indication information, and selectively turning on or off the receiving unit.
