## Abstract

An apparatus for transmitting broadcasting signal using transmitter identification and method using the same are disclosed. An apparatus for transmitting broadcasting signal according to an embodiment of the present invention includes a waveform generator configured to generate a host broadcasting signal; a transmitter identification signal generator configured to generate a transmitter identification signal for identifying a transmitter; and a combiner configured to inject the transmitter identification signal into the host broadcasting signal in a time domain so that the transmitter identification signal is transmitted synchronously with the host broadcasting signal.

## Claims

### Claim 1

A method of receiving a transmitted broadcasting signal, comprising:
receiving the transmitted broadcasting signal;
generating a transmitter identification signal corresponding to the transmitted broadcasting signal, the transmitter identification signal being for identifying a transmitter; and
generating a host broadcasting signal based on the transmitted broadcasting signal,
wherein the transmitter identification signal is transmitted synchronously with the host broadcasting signal.

### Claim 2 (depends on 1)

The method of claim 1, wherein the transmitter identification signal is generated by using a TxID code generator including
a tier 1 register unit corresponding to a first generator polynomial; and
a tier 2 register unit corresponding to a second generator polynomial.

### Claim 3 (depends on 2)

The method of claim 2, wherein

### Claim 4 (depends on 3)

The method of claim 3, wherein
the tier 1 register unit includes registers which are preloaded to 0 except for x stage and a register which is preloaded to 1 for x stage, and
the tier 2 register unit includes registers which are preloaded by a 13-bit value corresponding to the transmitter.

### Claim 5 (depends on 4)

The method of claim 4, wherein a msb of the 13-bit value corresponds to a x13 register of the tier 2 register unit, and a lsb of the 13-bit value corresponds to a x register of the tier 2 register unit.

### Claim 6 (depends on 5)

The method of claim 5, wherein the transmitter identification signal corresponds to a transmitter identification sequence having a length of 8191 bits.

### Claim 7 (depends on 6)

The method of claim 6, wherein the transmitter identification signal is transmitted within a first preamble symbol period including a guard interval after a bootstrap of the host broadcasting signal.

### Claim 8 (depends on 7)

The method of claim 7, wherein a first signal corresponding to a first bit of the transmitter identification signal is emitted simultaneously with a first sample of a first preamble symbol including the guard interval, and a second signal corresponding to a second bit of the transmitter identification signal is emitted simultaneously with a second sample of the first preamble symbol including the guard interval.

### Claim 9 (depends on 8)

The method of claim 8, wherein the transmitter identification sequence
is emitted once within the first preamble symbol period when the first preamble symbol corresponds to Fast Fourier Transform (FFT) having a size of 8192, and
is repeated twice within the first preamble symbol period when the first preamble symbol corresponds to FFT having a size of 16384, and
is repeated four times within the first preamble symbol period when the first preamble symbol corresponds to FFT having a size of 32768.
