A UHDTV MUX 210 for generating a first terrestrial broadcast signal by adding a part of UHDTV data and generating a second terrestrial broadcast signal by adding null data to the remaining UHDTV data, and a first terrestrial broadcast signal for transmitting the first terrestrial broadcast signal. A terrestrial wave transmitter 150 and a second terrestrial wave transmitter 250 for transmitting the second terrestrial broadcast signal are included.

The HD broadcast signal input unit 100 according to the present embodiment includes an HD encoder 110 for encoding broadcast data compressed by MPEG 2 and an output of the HD encoder 110 to add null data and PSI / PSIP to add HD data. It includes an HD MUX 120 for generating a terrestrial broadcast signal.

In this embodiment, the HD MUX 120 outputs a broadcast signal of a reference 19.39 Mbps variable data rate, including video and audio data compressed by MPEG 2 at a variable data rate of 12 Mbps (9 Mbps to 18 Mbps). Is HD (or ATSC) broadcast data, and the remaining 7.39Mbps variable data rate is formed of null data.

In the embodiment of the present invention, since the HD broadcast is selected as the ATSC broadcast, the HD MUX 120 may be based on the ATSC MUX, which may be changed according to the selected HD broadcast standard, but is not limited to the present embodiment. .

The UHDTV input unit 200 according to the embodiment of the present invention outputs UHDTV broadcast data having a variable 25 Mbps data rate corresponding to 4K (3840x2160) level, and the UHDTV broadcast data includes video and audio data compressed by HEVC or MPEG4. .

The UHDTV MUX 210 according to the present embodiment receives the HD broadcast signal and the UHDTV broadcast data of the HD MUX 120 and the PSI / PSIP of the UHDTV, and outputs the first terrestrial broadcast signal and the second terrestrial broadcast signal.

For example, the UHDTV MUX 120 according to an embodiment of the present invention may include a time slicer that cuts and outputs the UHDTV broadcast data in units of time, and a portion of the UHDTV broadcast data separated by the time slicer, and null data of the HD broadcast signal. The second terrestrial broadcast signal is output by adding UHDTV PSI / PSIP and null data to the UHDTV sub-MUX that adds the first terrestrial broadcast signal and replaces the remaining UHDTV broadcast data separated by the time slicer. It can be configured to include the UHDTV main MUX.

In the present embodiment, the UHDTV MUX 210 detects null data output from a specific PID from an HD broadcast signal having a reference 12 Mbps variable data rate, and replaces the detected null data with UHDTV broadcast data to generate a first terrestrial broadcast signal. The first terrestrial broadcast signal according to an embodiment of the present invention may be output at a reference 19.39 Mbps variable data rate including HD broadcast data having a reference 12 Mbps variable data rate, UHDTV sub data and null data having a reference 6 Mbps variable data rate.

Or, it can be operated as sending to the ATSC & UHDTV MUX 302 and inputting the UHDTV data corresponding to the remaining 760ms to the UHDTV main MUX 303, but the setting of the time interval can be changed according to an embodiment. .

In this embodiment, the HD PSI / PSIP (or ATSC PSI / PSIP) is generated in the HD PSI / PSIP server (or ATSC PSI / PSIP server 320) to HD & UHDTV MUX (or ATSC & UHDTV MUX 302). The UHDTV PSI / PSIP is generated by the UHDTV PSI / PSIP server 330 and input to the UHDTV main MUX 303.

Meanwhile, the UHDTV PSI / PSIP server 330 generates signaling data including information for securing synchronization of broadcast data transmitted over two channels and tracking UHDTV sub data in a receiver that receives a UHDTV broadcast signal. It is possible to input to the UHDTV main MUX (303).

The first terrestrial broadcast signal (ie, UHDTV subdata) is transmitted using the additional channel, but is not limited thereto. The digital terrestrial wave in which the frequency and bandwidth of the basic channel through which the UHDTV broadcast signal is transmitted and the sub data of the UHDTV are transmitted are transmitted. The frequency and bandwidth of the channel may vary depending on the service policy and also depending on the country or region in which the service is performed.

In the conventional HD or HD receiver (or ATSC receiver 400) receiving the first terrestrial broadcast transmitted according to an embodiment of the present invention, the UHDTV broadcast data of PID to which null data is transmitted is regarded as null data and is HD broadcast. Only the data is decoded by the MPEG2 codec 410 to output conventional terrestrial channel broadcasting.

Meanwhile, the UHDTV receiver 500 receives the UHDTV broadcast signal through two frequencies, extracts the UHDTV sub data through the PID of the null data of the first terrestrial broadcast signal, and extracts the UHDTV main data from the second terrestrial broadcast signal. Input to the UHDTV DeMUX 510.

The UHDTV DeMUX 510 restores and outputs UHDTV broadcast data having a reference 25Mbps variable data rate, which is an output of a UHDTV encoder of a transmitter, and the UHDTV codec 520 decodes the UHDTV broadcast data to output the UHDTV broadcast.
