![]() ![]() If you have an older television or projector in the home, office, or classroom that still works well but does have RCA input port only.So the term AV means the composite AV or RCA in here. The composite AV cable is the classic RCA cable mentioned above. There are many types of AV cable, but most are either component AV cables or composite AV cables. RCA cables were created by the Radio Corporation of America in the 1940s, hence the name RCA. These connect to the corresponding male jacks of the cable. The typical three-jack AV ( RCA jack) setup on most entertainment equipment includes a yellow sleeve for video, a red sleeve for the right audio channel, and a white sleeve for the left audio channel of stereo audio. It has become a generic term used in home entertainment setups and products and is usually connected through some sort of RCA cable. In this blog I will use in Donald Trump’s word to describe these two devices for the consumers who have no any technical background.ĪV is an abbreviation for audio/video. There seems to be some confusion for people with understanding which of these devices they need for the application they are setting up. But the cables I found are all RCA and component ones, not VGA, thus need some converter.For a technical person like me, I simply believe that the names ( or titles) of these two devices are reflecting their function very clearly, but it is my fault, many our customers purchased a wrong one and need a replacement in the past a few years. The passive cables are only useful if you have a device that is generating or expecting HDMI signals on a VGA connector, or VGA signals on an HDMI connector this is a non-standard feature, not implemented by most devices.įrom the last part above it seems that there are some monitors that accepts HDMI signals in the VGA port, so no conversion is needed. HDMI can only be used with older analog-only devices (using connections such as SCART, VGA, RCA, etc.) by means of a digital-to-analog converter or AV receiver, as the interface does not carry any analog signals (unlike DVI, where devices with DVI-I ports accept or provide either digital or analog signals).Ĭables are available that contain the necessary electronics, but it is important to distinguish these active converter cables from passive HDMI to VGA cables (which are typically cheaper as they don't include any electronics). That's highly strange because AFAIK HDMI doesn't support analog signal transmission, and indeed it's doesn't If both input / output device do not support signal conversion, a signal conversion box is required. In order for these two formats of signal to communicate with each other, both input and output devices needs to support the signal conversion function (code and decode), please kindly check with your user manual. As HDMI carries digital signals while RCA carries analog signals.This cable functions as a signal transmitter, but NOT a signal converter.They come in various forms, from component only, composite + audio to component + audio ELEC 5ft HDMI Male to RCA Video Audio AV Cable Adapter for PS3 PS4 Xbox One Wii.HDMI Male to 3 RCA AV Cable Lead 1080P HD Convert Line.HDMI to 5RCA Male to Male Video Audio Cable Converter Adapter Cable.Kebidu 1m Wholesale 1080p HDMI Male to RCA Male Adapter.While looking for some HDMI-to-RCA converters I found out that most of them are simple cheap cables from China without any conversion circuits
