Description

[0001] The present invention relates to a method for displaying loudness broadcasting signal information on a screen in a 4K and HD video and audio multi-format loudness monitoring system,

The present invention relates to a method for displaying loudness broadcasting signal information on a screen in 4K and HD video and audio multi-format loudness monitoring systems, and more particularly, to a method for displaying information on 4K video and audio multi-format loudness processes (4K) video and audio multi-media for providing a graphical user interface (GUI) for displaying video and audio information on a 4K signal-processed screen and multi-formatting for loudness information processing And a method of displaying loudness broadcasting signal information on a screen in a format loudness monitoring system.

People are exposed to various sounds while they are living in various environments.

The sound that people are exposed to is caused by various causes, such as environmental noise that causes unpleasantness when the person listens, multimedia sound and music that entertains the person, and sounds that occur when people communicate and exchange information .

Different sounds around people can cause pain, joy, and a variety of information depending on the size and type of sound.

This is because the human auditory structure perceives sound through the sound pressure level of the sound delivered to the air, so that the sound size and intensity are useful figures that define the auditory fatigue and physical characteristics of the sound.

Among the methods of evaluating sound, loudness is the subjective sound size perceived by the human auditory system when a sound is delivered to the human ear, and the intensity of the sound is the intensity of the objective sound transmitted to the human auditory system Which means the power of sound, usually measured in decibels well known.

Typically, conversations between people are between 60 and 70 dB, traffic is heavy, noise is about 80 dB, and people generally feel comfortable in the range of about 70 dB.

Modern people are getting more and more opportunities to interact with audio, and with the development of portable multimedia audio devices, they can enjoy their favorite multimedia contents and music anytime, anywhere.

In particular, with the advent of MP3 (MPEG-1 Layer III) in the late 1990s and popularization of the Internet in audio, it became possible to easily download and listen to MP3 compressed digital music through the Internet.

The commercial audio source market has rapidly expanded with the popularization of multimedia devices, and the audio source has become more competitive in the area, so that the dynamic range of the maximum reproducible sound and the minimum sound difference of the audio source And the maximum value of the waveform was increased, so that the audio sound size was significantly increased.

On the other hand, in order to maintain the volume of the digital broadcasting program and the broadcasting advertisement provided by the broadcasting company at a certain level, a volume standard and an operation method are prescribed, and a monitoring device for monitoring the broadcasting signal according to the regulation is 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 .

Meanwhile, in displaying the 4K and HD signal processing related to the present invention on a screen, a GUI (Graphic User Interface) for displaying information about video and audio and multi-formatting for processing of loudness information is required. However, It is proposed to display information of video and audio multi-format loudness signal which processes UHD 4K and HD signals without being present in one and two screens.
