Sony Trinitron Video Connection Types
By Steve Lander
Sony's Trinitron cathode-ray tube televisions, released in 1968, used special aperture grilles to provide higher video quality. Sony won a Technical Emmy for the Trinitron picture tube in 1973 and continued producing the TVs until 2007. By the time that they dropped out of production, Trinitrons offered a wide range of both digital and analog inputs.
High Definition Multimedia Interface
Towards the end of the Trinitron line's life, Sony started including HDMI jacks. These jacks support high definition digital content including Blu-ray content that is encrypted with the High-bandwidth Digital Content Protection (HDCP) system. With a single wire, HDMI carries high resolution digital video and digital audio, making it easy to connect HDMI sources to Trinitron TVs.
The Component Video connector separates a high definition analog signal into three different channels. The Y channel, usually color-coded green, carries a black and white version of the signal, The other channels, usually color-coded red and blue, carry color difference information which the Trinitron set interprets to generate the image's color. Component Video connectors do not carry audio, so Trinitron sets also have dual analog audio inputs -- one for the left channel and one for the right.
S-Video connectors are a higher-quality standard-definition video connection. They have a round plug with a location key and four pins. One pin carries the same information as the green "Y" channel in a component connection. The other pin contains all of the color information for the signal. Separating the "luminance" from the "chroma" gives S-Video connections better video quality than Composite Video connections. Your Trinitron's S-Video connection has a separate audio connection, as well.
Composite Video connections, which use the same phono plugs as Component Video and analog audio connections, combine the entire video signal into one wire. Typically color-coded yellow, they are the easiest way to connect a video source to your Trinitron but usually offer the lowest video quality. Since they do not carry audio, you will need to use them with a separate audio connection.
Trinitron television sets with tuners also have F-type coaxial connections. These connections accept the kind of screw-on connectors that cable television uses and are usually used to feed a radio frequency signal into the set. The F-type connector connects your TV to an antenna, a TV cable or to a video device that generates its output through an RF modulator onto a TV channel -- usually channel 3 or channel 4. It carries both audio and video.
