Video and audio connections to television were added to televisions from the very first working television ever made in 1925. They have always been available on some (but not all) models ever since.
Video is picture and audio is the sound. Home theater receivers have RCA composite or component, S-Video or HDMI for the video input, and RCA analog, Toslink (optical) or coaxial inputs for digital audio.
No i think it has to do with the audio in TV's but i do know it has nothing to do with video.
Composite video input for video and analog audio cables for audio.
The yellow cable is the video. It plugs into the yellow video input jack. The white and red, or black and red cables are left and right audio. The connect to the audio in or out jacks.
Connect Audio out on the box to Audio In on the TV set. Make the same connection for the VIDEO. Use Input 1 on the TV then select Video 1 on the remote, Use the INPUT button.
No, it is the processing unit. The input would be its controller, output could be the video and audio as well as its rumble (if you have a controller with rumble).
A switcher that will connect 2-3-4 other devices such as a camera, vcr etc. one at a time to a single audio/video input on the TV set.
Yes but if there are audio/video connectors use them, you will get a better picture and audio.
For this purpose, you will have to download a program like ScreenRec. ScreenRec not only records a video but accepts audio input too.
The optical input on a TV is used for transmission of digital audio, in SPDIF format between devices, only.
Connect the av cable video plug to the composite video in (yellow). Connect the left and right audio to the stereo audio input, or connect these to your surround sound system.
The system does no video switching, a audio only system, where other systems will switch AUDIO and VIDEO both at the same time.OR if it is a A/V type it means the unit has some inputs that do not have video such as a CD Player. This is normal.
