RCA connectors were developed in 1940 by Radio Corporation of America and have been the most common analog video and audio connectors till today.
However, modern equipment with much greater resolution and quality demand the use of High Definition Multimedia Interface(HDMI) for their increased bandwidth and quality. Therefore there is an obvious need for ways to convert signals between RCA and HDMI connectors.
In order to achieve the signal conversion, you need an active converter box with a power supply (optional) and electronics inside to do the analog to digital conversion.
AGPtek Mini HDMI to AV converter
This very affordable gadget is easy to use and portable. If your need is just to output 480i or 480p HDMI signals then this is the device for you.
It doesn’t require external power and the converted signal is free of any noise. The video output is clean and crisp with good color translation and perfect audio across all frequencies. This only works if the user remembers to set the output resolution to 680*480 and audio mix to stereo. Anything above this results to low and distorted output.

There is a trendy HDMI to RCA cable that is in the market. Some shoppers may get confused by the name and find themselves purchasing the cable in the hope of converting signals from RCA to HDMI.
