I want to create this guide to help others with Televisions and Video connections.
First off, I going to skipp the issue of HDTV lag since poonage already wrote a HDTV FAQ. It is a great guide and I want this guide to complement poonage’s guide and I might reference to it a few times, but I not trying to replace it.
First Analog connectors and signals
RF stands for Radio Frequency.
This is your standard connector for 90% of the Televisions out there in the world.
RF also is subject to the most image quality lost and interference.
RF uses ether Twin-lead or coaxial cable the most common is coaxial. Games that uses a RF Switch usually broadcast on Channels 2 or 3.
RF is also used for Antennas on Digital TV with the ATSC standard instead of NTSC.

Composite video Not to be confused with Component video.
Composite video is recognized by a yellow RCA jack, sometimes accompanied by a red and white audio RCA jacks. Composite is the next most common connector.
This connector is what Gaming systems used most often.
Used with DVD players, Game systems and various set top systems.
The Video information is separated from the audio to reduce signal degradation.
It is not unusual for the yellow video RCA jack to be connected to 1 device and the Red and White Stereo audio jacks are connected to a 2nd device like a stereo or a amplifier.
From this point forwards all the other Analog connectors uses RCA jacks for Left and Right audio (except SCART connectors).
** S-Video** Not to be confused with the video tape format S-VHS
Separate Video, also known as S-Video, Y/C, and sometimes incorrectly referred to as S-VHS or Super Video is an analog video transmission scheme, in which video information is encoded on two channels: luma (luminance, intensity) and chroma (color). The Separated luma and Chroma reduce some interference. Capable of transmitting 480p (analog). S-Video used a version of Mini-DIN as its connector.

Component video Not to be confused with Composite video.
Component Video is a video signal that has been split into two or more components and is a analog format. Component can refer to luma and chroma spiting or RGB (Red, Green, Blue) / YPbPr
* Y carries luma (brightness or luminance) and synchonization (sync) information * PB carries the difference between blue and luma (B ? Y) * PR carries the difference between red and luma (R ? Y)
Component video is capable of carrying signals such as 480i, 480p, 576i, 576p, 720p, 1080i and 1080p, although some gaming systems will have their own limitations.

VGA or Video graphics array is often used for Computers. VGA is made obsolete by DVI, which is the new standard on PC Monitors. First introduce by IBM in 1987. For our purposes we focus on VGA as the connector a 15-pin D-sub and not the original VGA resolution of 640×480. A few gaming system supports these such as the XBox 360 and the Dreamcast, other systems would require converter to display in though VGA. Many HDTVs have a VGA port.
SCART (Syndicat des Constructeurs d’Appareils Radiorécepteurs et Téléviseurs) is a 21-pin connector for connecting audio-visual (AV) equipment together, Also known as Euroconector or EuroAV in Asia and EIA Multiport in North America.
In Europe, SCART is the most common method of connecting AV equipment together, and has become a standard connector and not common else where in the world.
SCART is becoming obsolete with the introduction of new digital standards such as HDMI. SCART transmists Audio, Video, Data and can have AV equipment daisy chained together. SCART is not Bi-directional and can not support non RGB (or YPbPr) signals. Due to high voltages, hot plunging SCART connectors are not advised.
