Component Video is also called YPbPr, or YCbCr and
transmits the picture information in a luminance and phase-opposite
chrominance pair over three coax cables [Red, Green, and Blue].
RGB [Red, Green, Blue] is some times also called Component Video,
but combine the color, black and white signal
YPbPr is 'sometimes' used when discussing the three-wire analog
video component interface EIA-770 [EIA-770.2-a SMPTE-240M and others].
The luminance (Y) is represented separately from the color components (Pb
and Pr).
In some cases The Y output is provided as a Green jack, the Pb is
provided as a Blue jack, and the Pr is provided as a Red jack. The 'Y'
signal carries the black and white information, The 'Pb' and 'Pr' signals
carry the color difference signals.
YCbCr is used when discussing a digital component interface
ITU-601 or ITU-656 digital interfaces (formerly CCIR-601, CCIR-656).
Y is Luminance, Cb is Blue Chromanance, and Cr is
Red Chromanance. CCIR-601 defines an 8-bit DIGITAL 2's compliment coding
for component video
RGB is the component format in which the primary colors (red,
green, and blue) are transmitted as three independent components. The
color, black and white signals are combined within these three signals.
Only using RGB inputs requires separate horizontal and vertical sync
inputs. RGB presents a better [TV] signal than the other forms of
Component video, S-Video, Composite Video, or RS-170. RGB sends each
signal on a separate cable and does not mix the color signals.

Single "Yellow" (shielded) RCA jack [75 ohm coax cable], which is not to
be confused with the Audio (Red and White) jacks of the newer three cable
systems, or just a single black wire in the older systems. It's a
composite of the black-and-white information (Y) and the color
information (C). Composite Video may also be called VBS [Video, Blanking
and Syncs], or CVBS [Color, Video, Blanking, and Sync].
The video signal is on the yellow cable, while the white carries the left audio and the red carries the right audio.
S-Video is better
than Composite Video, and Component Video is better than either of them.

Although the Composite Video interface is still found on Audio-Visual gear as of 2010, you don't want to use it.
The next better video interface is S-Video [below], again the A/V gears needs to have the interface.
Of course if you have no other option than Composite video it is. However these days Composite Video is used a little differently.
The Composite Video interface is used in combination Component Video, as the audio input. Recall that Component Video is video only with no audio input.
So when you use Component Video between devices, you may also be using the white and red cables of Composite video to hold the left and right audio channels.
These days, the HDMI cable is the one you want. But you still need to retain compatibility with your old gear.

Digital Visual Interface [DVI] .. standard for high-speed, high-resolution digital displays. Developed by the Digital Display Working Group (DDWG). Refer to the DVI page for additional info and connector pinout, signal names and a description {This web site} Digital Video Broadcasting/Digital Audio-Visual Council (DVB/DAVIC),
developed by DAVIC [inactive] and DVB and adopted by European Telecommunication
Standards Institute (ETSI) and International Telecommunication Union

SCART: Euro-Audio/video connection system to BS 6552:1984 (EN 50-049). Provides the physical and electrical interconnection between two pieces of audio-visual gear. May also be called "Euro", or "Perri" connector. The SCART connector pinout is shown in the table below

Serial digital interface [SDI] standard is based on a 270 Mbps transfer rate, over a single 75 ohm coaxial cable, up to 600 feet. Serial Digital Interface is a digital broadcast television standard providing digital encoding of standard NTSC and PAL formats, with embedded audio. SDI is used in Television stations, cable channels, and professional production Equipment. Refer to the SDI page for more information.

The coax cable shown above would also work as an analog antenna input as well.
Which would be the Tuner input or Antenna input on your TV.

S-Video [Super-video] sends video signals over a multi-wire cable,
dividing the video information into two separate [75 ohm coax or twisted
pair cables] signals: one for luminance (Light) 'Y' and one for
chrominance (Color) 'C'. Each signal is sent shielded, inclosed in a
4-pin Mini-DIN. S-Video is synonymous with Y/C "Component" video. However
Y/C is the correct term, but the term S-Video is widely used to indicate
the interface when in fact refers to a VCR tape format. |
.. 
Although S-video did work well in the latter days of VHS tape drives,
You really want to at least upgrade to Component Video [above].
Or better yet a digital interface like HDMI.
DisplayPort: The DisplayPort interface: is listed on its own page.
RS-170 EIA/TIA-170 Electrical Performance Standards - Monochrome Television Studio Facilities. RS170 is now listed on the RS-170 page.
High Definition Multimedia Interface, Refer
to the HDMI page.
The High Definition Multimedia Interface HDMI cable
supplies both high-definition video and multi-channel, digital audio for
consumer Audio Visual [AV] entertainment equipment [HDTV, Amplifiers].
The HDMI interface is all digital, with no analog signals. HDMI is
backward compatible with the DVI interface, but without the more advanced
upgrades and no audio. Converters for HDMI to DVI cables are being
produced. The HDMI cable is 5 meters in length and uses 28 AWG wire.
