② Service information

The reception status of the broadcasting service of the NIBS is classified by the type / resolution of contents (HD contents, 4K contents, 8K contents). In the case of a content having a good reception status, it is displayed in a green color. In the case of a content which is not received, it is displayed in a red color.

③ Device information

Indicates the connection status of the RF receiving device.

④ Channel information

You can view and set the current tuning frequency and bandwidth of the RF receiving device. The frequency can be set to 42 ~ 870MHz and the bandwidth can be set to 1.7 / 5/6/7/8/10 MHz.

⑤ Timer & Control

⑦ Signaling information

The specific information contained in the service information contained in the NIBS service signal is displayed.

⑧ Media information

Media information analyzed through MPU parsing is displayed. Real-time information of the MPU included in the corresponding area is displayed. The segmentation is for 8K content.

4K contents can be divided into four areas (Area1, Area2, Area3, Area4), and the divided 4K contents can be processed as independent assets, and each 4K contents can be encoded into SHVC So that three layers L0, L1 and L2 can be generated for each region. Accordingly, the 8K content is composed of 12 (= 4 * 3) layers, that is, 12 assets.

In the media information, an area in which an error has occurred can be displayed in a different color from an area in which no error has occurred. Further, in the media information, it is possible to display information on whether or not media is missing for some of the areas of the content, and to display information about whether there is a mismatch in some or all of the areas of the content .

Hereinafter, the NIBS analysis engine 144 shown in FIG. 2 will be described in detail with reference to FIG. 5 by a process of monitoring and analyzing broadcast data. 5 is a flowchart provided in the description of the NIBS monitoring method according to another embodiment of the present invention.

5, when the NIBS monitoring starts (S210), the NIBS analysis engine 144 selects the RF (S220). When the broadcast receiving device is recognized and locked, the RF data is acquired.

The monitoring start in step S210 can be inputted through the command '5) Timer & control', and the RF channel selection in step S220 can be confirmed and set through '4) Channel information'.

In this process, the NIBS analysis engine 144 analyzes '③ device information' and '⑥ RF status information', and the RF single display unit 145 exposes it (S230).

Next, the NIBS analysis engine 144 receives and parses the MMTP packet, and divides it into MPU data and signal data according to the packet type.

For the MPU data, '⑧ media information' analyzed through MPU parsing and MFU parsing is displayed through the MPU information exposing unit 148 (S250). In the case of the content received only through the broadcasting network (content including only the base layer L0), the service information is displayed through the MMTP information exposing unit 146 (S260).

The signaling data 'parsing information' parsed through signal data parsing is displayed through the signaling information exposing unit 147 (S270).

Meanwhile, the NIBS analysis engine 144 acquires enhancement layer data through a communication network when it is determined that enhanced layers (L1 and L2) are to be received through the communication network through the signal data.

In this process, the '② service information' analyzed by the NIBS analysis engine 144 is displayed through the MMTP information exposing unit 146 (S280).

Hereinafter, the RF data reception process will be described in detail with reference to FIG. 6 is a flowchart provided for explanation of the RF data parsing process.

6, when the RF receiving device receives the RF data, the NIBS analysis engine 144 checks whether the length of the Read Frame does not exceed the length of the MTU (Maximum Transmission Unit) .

When the error count reaches the ERROR_THRESHOLD value continuously, the program terminates. If there is no error, the RF data is analyzed by Get_RF_Value () and the frame data is transferred to the buffer through the Write_RF_data () function.

Hereinafter, the process of analyzing the '⑦ signaling information' and the '⑧ media information' will be described in detail with reference to FIG. 7 to FIG.

Figure 7 is a flow chart provided in the description of the MMTP parsing process. The RF data received through the process shown in FIG. 6 is divided into MPU, MPU medata, and signaling information, as shown in FIG.

In this process, when the packet_counter error occurs, data is not transmitted and the program is terminated when ERROR_THRESHOLD or more occurs. Check packet_counter checks the continuous value of the count regardless of the packet_id, and Check sequence & fragc_counter checks the continuous value of the count by the packet_id. The payload of the corresponding data is configured according to the sequence and frag_counter values, and all the buffered data can be deleted according to the packet type upon occurrence of an error.

Figure 8 is a flow chart provided in the description of the signaling parsing process. The signaling is basic information for configuration information and decoding between contents, and is obtained through the process shown in FIG.

A message filter separates messages such as PA message, MPI message, and MP message, separates the table by a table filter, and transmits it to the resolution table parser. 8 shows information obtained from the main table.

Acquire CI through MPI_table to obtain area and asset information, and acquire location and group relation of asset through MP_table. Then, the type of content and the size information of the content are acquired through the DCI_table. The information thus obtained is transferred to the decoder and used for media management. Signals are acquired as soon as they are detected, but they are not updated if they are the same.

9 is a flowchart provided for explanation of the MPU parsing process. When MPU is parsed, MPU header is parsed and mfu parsing is performed to obtain sample information. If there is group information in the signaling information, the same sample belonging to the same group is acquired. If the recoding function is enabled, you can create a dummy file.

10 is a flowchart provided in the description of the process of generating the NIBS monitoring screen. As shown in FIG. 10, the NIBS analysis engine 144 receives the broadcast data, updates the existing information, acquires the RF status information, the signaling information, the media information, 148 present updated information.
