Digital Broadcasting System
Digital broadcasting system based on artificial intelligence
Sound tuning process is essential because acoustic equipment has problems in that the sound output is distorted due to reflection according to the amplitude characteristics, overlapping sound waves, and reverberation due to the structure of the installed building and the indoor environment. However, the reality is that it is difficult to tune the sound unless you are an expert because sound tuning is influenced not only by technical factors such as frequency analysis, but also by personal sound techniques such as the sound experience, know-how, and sensory characteristics of the tuning engineer. This tuning process is automatically controlled by calculating the optimal acoustic tuning data using an artificial neural network device that has learned acoustic data, so that even non-experts can easily tune the sound and optimize the sound quality.
By generating test signals such as pink noise and using an artificial neural network that has learned the optimal acoustic tuning for automatic tuning, the acoustics of acoustic equipment are automatically tuned and optimized for each frequency band. Learning parameters of artificial neural network device: You can learn along with measurement data using the size, shape, structure, and material of the acoustic equipment installation space. In order to reduce measurement error, automatic tuning process is repeatedly performed until it is determined that there are no more optimization values.

System configuration
In general, in the case of the broadcasting system used in the past, it was difficult to adjust the volume and sound quality depending on the situation outside the broadcasting control room because the broadcasting operator can only operate or control the broadcasting operation within the broadcasting control room. For example, when it is necessary to control the volume of music or when it is necessary to adjust the sound quality according to the speaker when using a microphone, the broadcast operator goes out of the broadcast control room to check the external situation or volume, and then enters the broadcast control room to operate the broadcast. Or, we had to operate inconvenient broadcasts depending on the circumstances outside the broadcast control room by means of hand signals and walkie-talkie communication with assistants.
GV Korea's digital broadcasting system directly recognizes the situation inside the premises from outside the broadcasting control room, and uses a remote control device to control multiple volume and EQ control functions for broadcasting sounds operated inside the broadcasting control room through a wireless network. It has the feature of remote control individually or as a whole.
