Audio visual devices are such items as DVD players and video game consoles. An audio-video distribution system will determine the quality of sound and visual elements in your home entertainment systems.
Types
Any DVD player, video game system or TV built in the past 10 years contains an audio-video distribution system. An audio-video system contains components to reproduce sound you would get from DVD players or video game consoles. These systems usually contain speaker imports for your home entertainment systems to carry amplified sound. It also reproduces video signals from these consoles. Audio-video distribution systems also come with an adjustable bass reflex. This mechanism enables you to adjust the amount of sound and bass coming out of you subwoofers and other speakers plugged in to your system.
Function
Most audio-video distribution systems run off of AC or alternating current. Some portable systems may take batteries or DC power. One piece of equipment that can use an A/V system is a laser disc player--it has a Dolby digital RF modulated signal. Because of this, signals have to be converted into digital bit streams before being used in an audio-video distribution system receiver and amplifier.
Significance
These systems have to use an accelerometer to register the acceleration, so they can deliver correction signals through a feedback circuit. This makes sure the waveform of the output is equal to that of the input.
Audio-video distribution systems use an analogue-dialogue normalization system to maintain a uniform level of Dolby digital software when switching between screen titles.
Benefits
Another audio assistant mechanism is the amplifier. This device will increase the level and power of input signals. Amplifiers consist of two main parts: the control amplifier for level control and the tonal adjustments with a power amplifier that is able to deliver enough current to power loud speakers.
Function
The video side of an audio-video distribution system uses twice the resolution and detail as VHS. You also have soundtracks with dialogue of up to 8 languages, with subtitles of up to 32 languages. These systems are found at most video and electronic stores.
