When determining what kind of audio/video needs you have, you first need to look at what quality you want the equipment to possess. If you’re alright with standard-definition there is a specific cable connection and equipment available for you. However, if you want high-definition signals and quality, there is a completely different cable connection and hardware you need.
Standard-Definition
Standard-definition video signals have a horizontal resolution of 480 lines. With this audio/video connection option you need RCA audio video cables. This is a set of red, white and yellow circular cables available at any electronics store. To hook up the equipment, plug the red white and yellow cables into the “Video Out” ports on on the device you want to send the signal from. Insert the other ends of the cables into the “Video In” ports on the television.
High-Definition
When you want high-definition video signals, you need a single HDMI cable. This provides full HD audio and video signals in a single cable. Connect one end of the cable into an “HDMI Out” port on the device you want to send the audio/video signal from. Plug the other end of the cable into an HDMI port on the television.
