Dolby Digital is a built-in decoding device that creates six-channel audio from satellite digital broadcast programs or multimedia video content recorded on digital video cassette, digital audio cassette or from a video server.

What is a dolby digital decoder on a TV?

The Dolby Digital decoder is presented as a perfectly clear sound system. The channels (left - center and right - front) allow you to set the location of the sound source. Separately distributed channels captivate the viewer with enveloping sounds flowing from the screen.

Why is a dolby digital decoder needed on a TV?

The Dolby Digital processor is a continuation of the previously implemented Dolby multi-channel audio encoding system. In the absence of a noise reduction signal, Dolby works on the principle of noise reduction, and if it is present, it allows a powerful, productive audio signal to interrupt lower-level noise. That is why this technology uses a psychoacoustic model of hearing.

Attention! If the signal fills a particular part of the spectrum, Dolby noise reduction reduces the noise level in certain parts of the spectrum where there is no productive signal, making it insignificant. This occurs because the audio signal only masks nearby frequency noise.

The Dolby Digital set-top box covers many other reserves:

• increases device resources, guarantees high-fidelity sound transmission in 5.1 format;
• creates true 5.1 stereoscopic sound using various stereo headphones;
• increases the sound distance when using speakers for musical sound reproduction;
• produces the creation of spatial perception when using stereo headphones.
• enhances low sound frequencies;
• enhances high frequencies and improves the sound quality of music by correcting the effects of high-frequency impulses;
• adds significance to mono sound reproduction;
• Controls sound levels by maintaining a stable volume level.

How to use dolby digital decoder

In order to configure a system device, the TV must support standard settings.

At the same time, video recordings must also comply with the DD+ format. As a rule, it is used on all BluRays and on selected commercial channels.

To transfer Dolby Digital Plus video content from the video player to the TV, and then to the equipment of the multimedia complex, you will need a standard HDMI 1.3 cable.
