All About 1920p Resolution Plasma Hdtv

You may have an expensive flat screen TV but unless you use the best connections for flat screen TV you can get, you will end up with nothing but a fair A/V (audio + visual) experience!

Here I shall explain the most commonly used and best connections for flat screen TV also when to use them!

Line Input / Line Level

Line level is the signal level outputted by virtually all domestic audio equipment. Usually A/V equipment can be connected using RCA phono connections with white and red (White for left, Red for right) connectors for a stereo signal. Any equipment you see with these connections is usually outputting or inputting a line level signal.

RF

The RF (Radio frequency) or (F connectors) also called (input and output) connections (as known outside Europe) are DRM (Digital rights management) free you find them on most A/V equipment. The first transmission of TV Pictures using RF was in 1938!

Composite

Composite video is for the picture only and is used usually as a cable with an RF type connector for A/V appliances. This connector is usually yellow.

The question: Which are the best connections for flat screen TV?

Around 2005 HDMI was brought to us as the new standard connections for flat screen TV. High-bandwidth Digital Content Protection (HDCP) was placed in a lot of new HDMI A/V devices and is now taking over as standard practice.

Your TV will still work with any pre 2005 connections (as you know!) But it won't have High-bandwidth Digital Content Protection (HDCP). In other words you can duplicate your A/V media much to artists dismay!

HDMI is the currently "so called" best connection, the difference between HDMI and the SCART connection is simple, one is digital - (HDMI) and the other analogue - (SCART) the difference in quality of A/V is so minimal to human senses it is practically unnoticeable to both naked eye and ear!

HDMI

Both HDMI and SCART use single connections for flat screen TV and other A/V equipment, both produce the best performances HDMI (digitally) SCART (analogicly). Some manufacturers have made their A/V equipment not function fully unless both devices contain the HDCP code.

Pre-2005 HDMI and DVI formats already displayed HD resolutions but without any digital protection (HDCP). The HDCP code is a signal sent from one HDCP enabled device and answered by the other HDCP enabled device. (Not all A/V devices use HDCP) yet!

In the UK I recently upgraded my Sky package to HD and the engineer who installed it insisted that I used a HDMI connection? A bit annoying as most of my A/V connections were by SCART, was I expected to change them all?

Well luckily for us, using Sky's directions on their website, there is no need! So I just use both!

SCART

From the French (Syndicat des Constructeurs d'Appareils Radiorcepteurs et Tlviseurs) the SCART or (Euroconnector) as its sometimes called, has been the standard connector used in Europe since it was designed in the 1970s. The SCART can connect all A/V devices that are SCART compliant with one lead to another (very tidy!), it does not have the HDCP as it came way before the idea of HDCP.

Optical Digital

Optical Digital connection is for passing digital audio from one component to another. The digital information is converted in to light and the transmitted along a fibre optic cable. Optical digital can carry Dolby Digital, PCM and DTS Audio formats amongst others. On most home equipment a "Toslink" interface is used as pictured above, but some, such as portable devices also use a 3.5mm jack

Component Video

A high quality video connection found on video sources like DVD & Blu-Ray Disc and for switching between them on amplifiers/receivers and of course on display devices like plasma, projection etc... Component Video can also be used for carrying the signal when DVD players have Progressive Scan output Labelled as "Y" "Pr" and "Pb."
"Y" is luminance, luma, or "Brightness" This describes the level of white (or black).
"Pr" is the level of Red
"Pb" is the Level of Blue
The green section of the final colour output is derived from the levels of red, blue and white level, whatever the difference present in the the white level after subtracting blue and red must be green

On most home equipment a "Toslink" interface is used as pictured above, but some, such as portable devices also use a 3.5mm jack.

This book provides a full and comprehensive coverage of video and television technology including the latest developments in display equipment, HDTV and DVD. Starting with TV fundamentals, the bulk of the book covers the many new technologies that are bringing growth to the TV and video market, such as plasma and LCD, DLP (digital light processing), DVD, Blu ray technology, Digital television, High Definition television (HDTV) and video projection systems.

For each technology, a full explanation is provided of its operation and practical application, supported by over 300 diagrams including schematic diagrams of commercially available consumer equipment. Where relevant, testing and fault finding procedures are outlined together with typical fault symptoms supported by photographs.

The new edition has a number of useful appendices on microcomputer/microcontroller systems, test instruments, serial buses (I2C and RS 232), teletext and error correction techniques.

The book is intended for students of electronics and practicing engineers. In particular, it will useful for students on vocational courses and service engineers as well as enthusiasts.

*The definitive guide to the new technologies transforming the world of television: HDTV, Digital TV, DVD recorders, hard disk recorders, wide-screen CRT, flat screen technologies...
*A practical approach, including troubleshooting and servicing information
*Covers UK, European and North American systems
