Description

SDR and HDR dual analyzer device [

The present invention relates to an SDR and HDR dual analyzing apparatus, and more particularly, to an apparatus and method for analyzing a video signal by acquiring a UHD SDR (Standard Dynamic Range) video signal or a UHD HDR (High Dynamic Range) video signal through a signal input terminal, And an SDR and HDR dual analyzing device for processing the analyzed result information so as to be output to the layout set in the display unit, respectively.

In order to keep the volume of digital broadcasting programs and broadcasting advertisements provided by broadcasters at a certain level, a volume standard and a method of operation are prescribed, and monitoring devices for monitoring the recognition of broadcasting signals in accordance with the regulations are being distributed.

Also, research on the method of measuring the size of audio signals started from the mid-2000s, and ITU-R BS, which is a standard for measuring audio signal size in ITU. ITU-R BS 1770-1 was announced in 2006 and added Gating method. The 1770-2 was announced in 2011.

In the published standards, only the method of measuring the audio signal size and the True Peak measurement method are presented.

The standardized audio signal size measurement method in ITU-R is measured through LKFS (loudness, K weighted, relative to nominal full scale).

Therefore, since LKFS is included in the broadcast signal, since a variety of audio signals and video signals are monitored on one screen in the case of the current monitoring apparatuses, a limitation point that a large number of monitoring information can not be conveniently displayed occurs, There is a disadvantage that it is not possible to quickly grasp whether there is a problem.

As a result, the broadcasting signal including the LKFS signal is provided on the multi-screen, so that the manager can smoothly process the signal during monitoring, and can quickly identify the problem in the event of a problem. In particular, a monitoring device capable of measuring the LKFS signal is required .

On the other hand, in displaying the 4K signal processing on a screen, a GUI (Graphic User Interface) for displaying video and audio information and displaying multi-format information about loudness information processing is required. However, this technique does not exist and UHD 4K signal And a technique for providing multi-screen information of video and audio multi-format loudness signals for processing video and audio signals.

In particular, a UHD HDR converter for broadcasting has been required to process a UHD HDR (High Dynamic Range) format for broadcasting related to the present invention.

The broadcast UHD HDR converter is a device for processing a digital image such that a bright part and a dark part are clearly displayed so that a photograph or an image is realistic.

HDR standard is divided into PQ-based SMPTE ST2084 HDR, Hybrid Log Gamma (HLG) led by BBC and NHK and S-log3 HDR Gamma led by Hollywood, consumer electronics and streaming company.

In the case of an HDR image which is incompatible with the HDR broadcast, when viewing it on a general SDR TV, the color may be seriously altered and distortion may occur.

From the standpoint of broadcasting companies, SDR images have to be produced in addition to HDR images, and services are also inefficient at the same time until viewers prepare HDR TVs.

HLG and HDR10 have been adopted as European next generation broadcast standard HDR Gamma because HLG can solve this inefficient situation.

Therefore, there is a need for a technology capable of analyzing signals between SDR and HDR signals and other HDR signals so that they can be watched regardless of broadcasting signal source as well as broadcasting signal processing. In addition to audio analysis, It is necessary to develop a technique capable of performing video analysis and outputting it on one screen at the same time.

Accordingly, in the present invention, a UHD SDR (Standard Dynamic Range) video signal or a UHD HDR (High Dynamic Range) video signal is acquired to analyze the video signal and the analyzed result information is outputted to the layout set in the display unit , The analysis result information includes a video image information for two image signals, image waveform information, color coordinate information, signal detail information, and audio state information for all audio channels, will be.

Hereinafter, embodiments of the SDR and HDR dual analyzing apparatus according to the present invention will be described in detail.

1 is a block diagram of an SDR and HDR dual analyzing apparatus according to an embodiment of the present invention.

As shown in FIG. 1, the SDR and HDR dual analysis apparatus includes a video signal acquisition unit 100, a video signal analysis unit 200, and a display unit 300.

The video signal obtaining unit 100 obtains a first video signal and a second video signal that are a UHD SDR (Standard Dynamic Range) video signal or a UHD HDR (High Dynamic Range) video signal through a signal input terminal 150 .

The UHD image has an image quality four times that of the HD image, which is defined as 4K UHD, and an image quality of 8 times the UHD image is defined as 8K UHD.

Particularly, as shown in FIG. 2, the UHD image is classified into SDR and HDR depending on the degree of color and brightness, and is represented by SDR (BT.709) and HDR (BT.2020).

In this case, SDR refers to BT.709, HDR refers to BT.2020, and 709 and 2020 denote the degree of color representation. 709), it is possible to provide a clear high-definition image because it has excellent color and contrast-expressing ability.

At this time, the video signal obtaining unit 100 obtains a UHD SDR (Standard Dynamic Range) video signal or a UHD HDR (High Dynamic Range) video signal through the signal input terminal 150, and provides it to the video signal analyzing unit Allow analysis to be performed.

For example, the first video signal input through the signal input terminal 150 may be SDR (BT.709), the second video signal may be HDR (BT.2020), and the first video signal may be SDR .709), the second video signal may be SDR (BT.709), the first video signal may be HDR (BT.2020), and the second video signal may be HDR (BT.2020).

Generally, a broadcast signal is composed of a header and a packet, a header includes PSI (Program Specific Information), a packet may include AV information and caption information, and a part of PSI information (Program Specific Information) It can be heard.

At this time, the video signal analyzer 200 analyzes the first and second video signals input through the video signal acquiring unit 100, and outputs the analyzed analysis result information to the layout of the display unit 300 .

That is, the information included in the header and the packet is analyzed and the desired information is output.

The desired information in the present invention may mean image information, image waveform information, color coordinate information, signal detail information, and audio state information for all audio channels.

That is, the analysis result information includes video image information, image waveform information, color coordinate information, signal detail information, and audio state information for all audio channels for each of the first and second video signals.

Accordingly, the display unit 300 outputs the analyzed result information of the first and second image signals analyzed by the image signal analyzer 200 to the layout, and displays the analyzed result information.

3 is a block diagram of an SDR and HDR dual analysis apparatus according to an embodiment of the present invention.

3, the video signal analyzing unit 200 of the present invention includes a video image extracting unit 210, an image waveform analyzing unit 220, a color coordinate analyzing unit 230, a detailed signal analyzing unit 240 An audio stream analyzing unit 250, and a screen division processing unit 260.

In addition, the central control unit 280 is generally constituted and is responsible for overall control of each of the above-described components.

The image extracting unit 210 extracts image image information from the input first and second image signals, and provides the extracted image image information to the image segmentation processor 260.

The image waveform analyzer 220 analyzes the input first and second image signals to generate image waveform information for the first and second image signals, and provides the image waveform information to the image segmentation processor 260 .

That is, the first image signal is analyzed to generate image waveform information, the second image signal is analyzed to generate image waveform information, and the generated image waveform information is provided to the screen division processing unit 260 do.

More specifically, referring to FIG. 5, the image waveform is waveform information of the currently displayed image, wherein the X-axis is the screen and the Y-axis is the brightness.

Brightness is a very important element of the image, so if you provide a waveform of the image, you can check the contrast of the current image.

The upper screen of FIG. 5 is an actual image, and the lower screen is an image waveform for an image of the upper screen.

At this time, because the left side of the image screen is dark and the right side is bright, an image waveform of the same shape as the bottom screen of FIG. 5 is generated.

For example, in FIG. 5, the length of the Y-axis is high in the bright portion and the length of the Y-axis is low in the dark portion.

That is, the length of the left Y-axis is much smaller than the length of the right Y-axis.

10, the waveform 340A of the first video signal HLG10 is expressed according to the following video image 310A, but the waveform 340B of the second video signal HLG10 is not represented It can be intuitively understood.

11, 340A represents a waveform of the first video signal 709SDR (310A of FIG. 11), and 340B represents a waveform of the second video signal HLG10 (the first video signal 709SDR to the HDR Transformed video) in the form of a waveform.

At this time, if the waveform of the first video signal before the conversion and the waveform of the second video signal after the conversion are compared with each other, it is possible to intuitively know that the same waveform is displayed and converted normally.

This is because the conversion does not convert the image but the color representation, so there is no difference in the image signal.

As a result, if the administrator compares the image waveforms with the desired image signals, the problem of converting the images can be grasped.

The color coordinate analyzer 230 analyzes the input first and second video signals and generates color coordinate information for the first and second video signals to provide the color coordinate information to the screen division processor 260 .

That is, the first image signal is analyzed to generate color coordinate information, the second image signal is analyzed to generate color coordinate information, and the generated color coordinate information is provided to the screen division processing unit 260.

The color error refers to a subtle difference in color and is called a color difference.

The reason for expressing the color difference is to define the color more accurately and to make the color management efficient through the color difference, and the color coordinate represents the difference between the color and the color.

The color coordinates generally use a CIE 1931 color coordinate diagram (Diagram of the CIE 1931 color space).

The color representation is expressed using the CIE 1931 (x, y, z) color diagram established in 1931 by the International Commission on Illumination (CIE), because the characteristic of the CIE 1931 color coordinate diagram is based on brightness , The green that gives the greatest effect on the brightness of the color is made the largest area, and the blue that shows the smallest effect is made the smallest area.

The mixing ratio according to the brightness of this color is 3: 6: 1 (R: G: B), and the green part is the widest because it is the brightest.

As shown in FIG. 6, it can be seen that the area of the color coordinates is wide in the order of SDR (BT.709) -> DCI P3 -> HDR (BT.2020) in the color coordinate system. It can be seen that the sharpness of image quality is better.

10, the color coordinate information of the first video signal HLG10 and the second video signal HLG10 may be represented by the color coordinate information of the first video signal HLG10 and the second video signal HLG10, The administrator can immediately check the problem of the currently broadcasted image through the color coordinate information.

10, the color coordinates 330A of the first video signal HLG10 are clearly displayed, but the color coordinates 330B of the second video signal HLG10 of the right side are not represented.

Therefore, the administrator can know that a problem has occurred in the current broadcasting.

11, reference numeral 330A represents the color coordinates of the first video signal 709SDR (310A of FIG. 11), reference numeral 330B represents the second video signal HLG10 (the first video signal 709SDR to the HDR The converted image) is expressed by the color coordinates of the converted image.

As a result, when the color coordinates of the video signals desired by the administrator are compared, it is possible to grasp the problems with the two images.

The detailed signal analyzer 240 analyzes the input first and second video signals to generate detailed signal information for the first and second video signals and provides the detailed signal information to the screen division processor 260 do.

That is, the first detailed signal information is generated by analyzing the first video signal, the detailed signal information is generated by analyzing the second video signal, and the generated detailed signal information is provided to the screen division processing unit 260.

As shown in FIG. 7, the header and packet of the received video signal are analyzed to generate detailed signal information.

For example, signal detail information such as bitrate: 12Ga, frame lock: locked, format: 2160p59.94, VPID: CEEAA001, HDR mode: auto, CRC error: --- is provided in the signal information area. color: normal, image status: live, and so on.

As described above, the reason why the detailed information on the signal is provided is that if the problem of the signal occurs, it is necessary to check the specification of the signal. Therefore, the detailed information of the signal is analyzed at the moment of inputting the video signal, .

11, 320A represents signal detail information of the first video signal 709SDR (310A of FIG. 11), 320B represents the second video signal HLG10 (the first video signal 709SDR is HDR Converted into a video signal).

As a result, the administrator can grasp the problem of the two video signals by grasping the detailed signal information of the two video signals.

The audio stream analyzing unit 250 analyzes the input first and second video signals to generate audio state information for all audio channels for the first and second video signals and provides the audio state information to the screen division processor 260 .

As a result, it is possible to check whether there is an abnormality in the audio stream for each channel.

More specifically, the input first video signal is analyzed to generate audio state information for all audio channels, and the second video signal is analyzed to generate audio state information for all audio channels. And provides the status information to the screen division processing unit 260. [

Referring to FIG. 9, each input video signal includes a maximum of 64 audio channels.

Accordingly, audio state information for all audio channels included in the input video signal is generated. There are four groups G1 to G4 per stream, and four pieces of audio information per group exist.

In the case of FIG. 9, since there are four streams (stream 1 to stream 4), a total of 64 audio channels exist.

At this time, the audio stream analyzing unit 250 generates audio state information for each channel and provides the audio state information to the screen division processing unit 260.

In this case, the audio state information is displayed by an audio level meter for checking whether an audio stream for each channel is abnormal.

As shown in FIG. 11, 360A represents audio state information for each channel of the first video signal 709SDR (310A of FIG. 11), 360B represents audio state information of the second video signal HLG10 (709SDR To the HDR) of the audio signal.

As a result, if the manager compares the audio state information of each channel with respect to the two input video signals, the administrator can grasp not only the video but also the audio problem.

The screen division processing unit 260 divides the display area of the display unit 300 into two first and second layout areas and divides each of the first and second layout areas into a plurality of detailed layout areas.

At this time, control is performed so that video image information, image waveform information, color coordinate information, signal detail information, and audio state information for all audio channels are displayed in the detailed layout area of the first layout area.

In the detailed layout area of the second layout area, video image information, image waveform information, color coordinate information, signal detail information, and audio state information for all audio channels are controlled to be displayed for the second video signal.
