DIFFERENCES IN QUALITY EVEN FOR DIGITAL SIGNAL TRANSMISSION!

WHAT IS THE DIFFERENCE BETWEEN THE REFERENCE HDMI

CABLE AND THE STAR HDMI

CABLE?

Many users are under the false impression that transmitting digital data generally works without any errors. something better or worse doesn’t seem

to exist. This applies to the Internet. There the recipient keeps asking the sender for the digital data until the content has been transmitted properly

(check test).

However in the audio/video sector, there is no time to compare digital data and request it again. so error correction is used for LCDs, LED-TVs,

plasmas etc. The more detailed and faster a certain picture sequence is, the higher the data rate is to be transmitted. The data rate is e.g. far higher

for a camera pan over the spectators in a football stadium than for an interview after the game.

However, the higher the data rate, the more errors are caused by the HDMI cable. Compression artefacts occur even though the screen has error

correction. The picture loses contour and focus. But these errors can be reduced with better cable quality. The more intricate the shielding, the more

superior the materials and the less the engineering tolerances at 100 ohm impedance are, then the lower the number of errors and better the picture

quality. even for short transmission distances.

That is why the picture quality is significantly higher with our reference HDMI cable, than the standard HDMI cable (see Figure). Fast camera

movements, detailed picture sequences and fast-moving action scenes gain in contour and picture sharpness. That is the difference.
