HDMI stands for High-Definition Multimedia Interface. Many high definition multimedia devices such as HDTVs are equipped with at least one HDMI port. An HDMI port may be used to either send or receive an uncompressed audio and video digital signal. Analog TVs, not being digital, are not equipped to receive HDMI signals. Therefore, in order to connect an HD multimedia device to an analog TV via the HD device's HDMI port, you need to pass the signal through an HDMI-to-RCA composite video converter before sending it to the analog TV.
Unplug all involved electrical devices.
Plug one end of the HDMI cable into the HDMI "Out" port located on the source device (the source device is the device with the digital signal). Plug the other end of the HDMI cable into the HDMI-to-RCA converter box.
Connect one end of the red RCA audio cable to the red RCA "Out" jack on the HDMI-to-RCA converter box (possibly labeled Audio "R"). Connect the other end of the cable to the red RCA "In" jack on the analog TV.
Insert one end of the white RCA audio cable into the white RCA "Out" jack on the HDMI-to-RCA converter box (possibly labeled Audio "L"). Insert the other end of the cable into the white RCA "In" jack located near the red RCA jack on the analog TV.
Plug one end of the yellow RCA audio cable into the yellow RCA "Out" jack on the HDMI-to-RCA converter box (possibly labeled "Video"). Insert the other end of this cable into the yellow RCA "In" jack located by the other RCA jacks on the analog TV.
Connect the power cord that came with the converter box to the power jack (typically labeled "DC") on the converter box. Then plug the power cord into a power strip or wall outlet.
Turn on the HDMI-to-RCA converter box, source device and analog TV set.
Switch the TV's video input channel to the A/V source setting using the "Input" or "Source" button on the TV's remote control.
Things You'll Need
HDMI-to-RCA composite video converter
Set of RCA audio/video cables
Check the HDMI-to-RCA composite video converter box’s specifications to make sure that the device is capable of NTSC video output. NTSC was the standard used in the United States to transmit, receive and decode analog TV signals prior to the switch to digital TV . If the HDMI-to-RCA composite video converter box is equipped for ATSC video output instead, which is the U.S. digital TV standard, you may have to connect the RCA output from the HDMI-to-RCA converter to a digital-to-analog converter box equipped with an analog pass through first. Then connect the digital converter box to the TV.
