## Abstract

Disclosed is an apparatus and method for providing a broadcasting service in a single frequency broadcasting network, and a system thereof. The apparatus for receiving broadcasting signals includes an RF receiver configured to receive an RF broadcasting signal having identification information to identify a broadcasting signal transmitter and down-convert the received RF broadcasting signal; a reception characteristic measurer configured to measure reception characteristics of the RF broadcasting signal based on the identification information and generate reception characteristic information; and a reception characteristic transmitter configured to transmit the reception characteristic information to a broadcasting system.

## Claims

### Claim 1

An apparatus for receiving broadcasting signals, comprising:
a radio frequency (RF) receiver configured to receive an RF broadcasting signal including identification information for identifying a broadcasting signal transmitter and down-convert the received RF broadcasting signal;
a reception characteristic measurer configured to measure reception characteristics of the RF broadcasting signal based on the identification information and generate reception characteristic information; and
a reception characteristic transmitter configured to transmit the reception characteristic information to a broadcasting system.

### Claim 2 (depends on 1)

The apparatus of claim 1, further comprising:
a controller configured to select the reception characteristic information equal to or larger than a predetermined threshold among the reception characteristic information and provide the selected reception characteristic information to the reception characteristic transmitter.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein the reception characteristic transmitter transmits the reception characteristic information to a network controller which controls the reception characteristics of the RF broadcasting signal.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the reception characteristic transmitter transmits the reception characteristic information to the broadcasting signal transmitter.

### Claim 5

A method for receiving broadcasting signals, comprising:
receiving an RF broadcasting signal including identification information for identifying a broadcasting signal transmitter and down-converting the received RF broadcasting signals;
measuring reception characteristics of the RF broadcasting signals based on the identification information to generate reception characteristic information; and
transmitting the reception characteristic information to a broadcasting system.

### Claim 6 (depends on 5)

The method of claim 5, further comprising:
selecting the reception characteristic information equal to or larger than a predetermined threshold among the reception characteristic information generated in said measuring the reception characteristic information of the RF broadcasting signals corresponding to the identification information to generate the reception characteristic information.

### Claim 7 (depends on 5)

The method of claim 5, wherein in said transmitting the reception characteristic information to the broadcasting system, the reception characteristic information is transmitted to a network controller for controlling the reception characteristic of the RF broadcasting signals.

### Claim 8 (depends on 5)

The method of claim 5, wherein in said transmitting the reception characteristic information to the broadcasting system,
the reception characteristic information is transmitted to the broadcasting signal transmitter.
