Generally, high-definition (HD) audio/visual devices, such as Blu-ray players or certain video game systems, connect to televisions through a high-definition cable, such as an HDMI cable. If you have a television with no available HDMI ports, you can still connect the HD device to your television by converting your HDMI cable to an RCA signal. To do this, you must build a makeshift cable using the original cables and a converter box.
Connect one end of your HDMI cable to the HDMI port on your audio/visual high-definition device.
Connect the other end of the HDMI cable to the HDMI port on your HDMI-to-RCA converter.
Connect one end of your RCA cable to the RCA ports on your HDMI-to-RCA converter. Your HDMI-to-RCA converter cable is now complete.
Connect the RCA cables on your newly constructed converter cable to the RCA ports on your television. Turn on your television and change it to its RCA input channel. You will see the signal from your high-definition device on your television screen.
