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. Depending on your needs, there are a variety of converter boxes in the market that can pull off RCA to HDMI conversions.
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.
AGPtek-CVBS RCA to HDMI
Next we have the AGPtek-CVBS RCA to HDMI 1080P Signal Converter Adapter Switch Box which is a bit pricey compared to the mini. As the name indicates, the gadget can convert analog CVBS and RCA signals to HDMI and is best suited for a user who has a resolution demand of up to 1080P.
The gadget also has a data center control, information distribution, conference room presentation and much more.It is easy to use and connects with most recent game consoles, HD players and DVDs.The output resolution can be set to the user’s liking and the output is free of noise and the video is super clear with fantastic color translations.

Finally we have the Coosis Scart and S-Video to HDMI 1080 Converter. This advanced device offers a very easy way to convert analog SCART, S-Video or RCA inputs to a digital HDMI output of up to 1080P resolution.
It accepts both PAL and NTSC formats and can take analog audio and encode it into the HD video signal for HDMI output. Each conversion is programmed with wide-range output resolution and 4 output image aspects ratios to meet different display requirements. It offers connections to almost all game consoles and players.
This is my device of choice so I may tend to be a bit bias but from experience. Coosis assures high quality output with an easy to use platform.
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. Please note that the cable is unidirectional in the sense that it supports only HDMI input and 3 RCA output.
