How to Choosing an HDTV – Part 3
Choosing HD Connections
In this section you’ll find detailed, easy-to-understand information to get the most out of your home theatre, so you’ll enjoy maximum performance with the best possible picture and sound.As TV manufactures don’t know what you plan on connecting, they generally include a variety of connections. Here you can view the differences between the connection types.
Most imposrtantly you’ll find out what connections you should use to hook up your new HDTV. Take a look this picture below, then read the explanation below it.
1. HDMI (High Definition Multimedia Interface)
This connection provides both audio and video. It delivers uncompressed High Definition Video (up tp 1080p with 16-bit colour) and eight channels of digital audio for 7.1 surround sound.
2. DVI Video (Digital Video Interface)
DVI has 24-bit colour which is ideal for high resolution displays, it’s found on many HDTV’s and computer screens. This connection sends a digital signal directly and does not need to be converted to digital, as opposed to the connections above.
3. Component Video (labelled as YPbPr)
Component connections are available on most High Definition televisions, DVD players etc. As the video signal is split in three it further improves picture clarity, color and sharpness above S-Videos.
4. S-Video
This connection is commonly found on many high quality and digital AV components such as VCRs, televisions and video games etc. It cannot send High Definition content. Due to less processing this cable will provide better picture quality than composite.
5. Composite Video (AV)
This is the most common video connector and is found on virtually every TV, DVD player and set-top box, not to mention camcorders and digital still cameras. This connector cannot be used to send High Definition video to a television.
6. PC Connections
PC/RGB Input (D-Sub)
Type: Analogue
This 15pin Connector enables a PC or other devices (such as Set Top Box that have D-Sub) to utilize the screen as a monitor.
7. Audio Connections
From left to right:
* Optical or Toslink (Surround Digital)
These fiber optic cables are commonly used to provide digital 5.1 or 7.1 home theater surround. Optical cables are immune to RF interference and electrical noise but can be subject to timing inaccuracies.
* Digital Coaxial (Surround Digital)
Digital Coaxial cables are orange in colour and are often confused for standard analogue audio inputs. This cable is used to deliver digital surround sound and has a wider bandwidth which produces less timing inaccuracy than a fiber optic cable.
* RCA (Stereo Analogue)
RCA or “line Level” audio cables deliver stereo audio sound signals via two cables, one for Left and one for Right. These cables typically use standard RCA jacks coloured red and white to connect components.

optical cables have lots of bandwidth compared to copper wires.,;
