Are there RC to HDMI converter cables available for connecting your DVD player RC output to HDMI input of your tv set?

"RC" is likely to refer to "RCA", the yellow jack that carries composite video along with the red and white RCAs that carry stereo audio.

There are a number of devices to convert composite video to HDMI and are commonly available online at trading and auction sites. They are priced at around $30 upwards and most do a reasonable job.

Some are described as up-converters, delivering 1080 line resolution instead of the 480 line or 576 line resolution of composite video. However, don't be persuaded that they will give you HD quality. Although they convert to an HD format, the image detail will still remain the same as the original SD signal. The converters are useful if you only have an HDMI input available but they will not improve the image quality. If you have analog RCA inputs on the television, they will provide the same quality of image as the converter will provide.
