RGB to Component (YUV) Video Converter £145.00 £115.00

Features


Designed to be the best RGB to Component (YUV, Y,Pb,Pr) video converter for Projectors and Plasma Screens.
Many screens give a superior picture via component video.
Compatible with RGB from any source, such as a DVD player, Sky Digibox, Freeview box, or Digital Cable.
Output of high quality Component (YUV) Video.   YUV is also known as Y, Pb, Pr and Y, Cb, Cr.
Broadcast quality synchronisation extraction using Plasma VGA technology.
Unique Computer enhancement for compatibility with copy protected sources
Switch video sources via an A/V amplifier that supports Component (YUV) Video.
Convenient connections to existing equipment - SCART input, gold plated phono output
Audio is passed though without modification to ensure optimum audio quality
Compact design with integrated power adapter - the best for reliable operation.

More Information


Designed to simply be the best, the RGB to Component (YUV) converter allows for RGB to be converted for use with Plasma screen, Projectors, Rear Projections TVs, A/V amplifiers and video line-doublers.  This offers a high quality video interface for domestic Audio Visual sources such as Sky Digital, On Digital, digital cable and DVD players.

Component (YUV) output.   Greater flexibility with plasma screens, where certain zoom modes may not be available.   Ideal for projectors that have component video inputs.   Allows for the component video input of video processors to be fully utilised.

Take advantage of component video switching on modern A/V amplifiers.   Ideal if you already have another component video source, use the A/V amplifier to control which source you're viewing.

Broadcast quality sync based upon the RGB to Plasma VGA unit's technology, superior to simplistic Sync Separators. Even in the presence of Macrovision copy protection, the RGB to Component Converter unit is able to keep true to the original source. Always stable, always with the correct line frequency.

Computer enhanced allowing for compatibility with Macrovision protected sources, such as DVD players, but still maintaining broadcast quality performance.   Removing the extra synchronisation pulses Macrovision adds helps to ensure a stable picture.

Output is via standard three Phono connectors.   High quality Component cables are available in the cables section.   Audio is passed directly to the two phono outputs without modification to ensure optimum audio quality.

Measuring just 150x85x48mm with a high quality integrated power supply, the RGB to Component (YUV) converter is compact and easy to use.

Constructed with components from some of the world's leading manufacturers and utilising a high-quality fibreglass PCB, this level of quality and detail is rare.   Designed and manufactured by J.S. Technology in the UK.

Technical Information

 

Component video, also know as both YUV and YPbPr, is derived via an arithmetic formula from RGB.   It is important to use YUV / YPbPr rather than colour difference signals in a home-cinema.   Since colour difference signals are not scaled, use of these would produce a strongly tinted picture.   The RGB to Component (YUV / YPbPr) converter strictly follows the correct conversion equations as detailed below.   In the above figure, RGB input is first mixed to produce the colour difference signals.   These are then scaled to produce the component video.

When converting video signals, it is important to maintain picture quality.   The RGB to Component converter uses discrete components to allow for a high bandwidth conversion process, maintaining picture detail.   While a simpler solution would be to use an off the shelf integrated circuit solution, it was felt this did not offer the conversion quality that J.S. Technology demands.

YUV is derived from RGB by the following equations:

Y = 0.3 R + 0.59 G + 0.11 B

U = 0.49 ( B - Y )

V = 0.87 ( R - Y )

 

U&V are weighted version of B-Y and R-Y to give the colour difference signals which refer to the Blue and Red colours respectively, green is not described as it can be derived from the above formula.    For more information on video signals, please refer to the Technical Briefing "Video Signals" in the Technical section.
