Contrary to popular belief, Digital Audio and Video is by no means perfect. During the data transfer some of the original data is lost or corrupted. Various error correction methods are used to fill-in or guess the lost data, resulting in an inaccurate representation of the original image i.e. poor contrast, un-natural colours, reduced 3-dimentionality, noise etc.

Like electronic circuitry, cables also have a significant effect on the signal quality because of issues related to their electrical properties. The quality of cables varies widely and therefore it is important to choose a cable that is able to deliver the desired performance.

There is a fundamental difference between the transfer of computer data and HDMI signals. Computers are able to transfer digital data without loss, because the data moves in the robust form of blocks, which do not depend on specific timing between the sending and receiving devices. However, digital video and audio signals are continuous streams of data, which are quite fragile, since the digital processor must remain perfectly locked onto the timing of the signal to avoid data losses.

The limitations of digital signal processors and cables create timing errors known as jitter, which remove portions of the audio signal and replace them with noise and distortion. Cables tend to round off the square waveforms of the signal, making them less clear to the processor, thus increasing jitter. This rounding effect varies greatly among cables and truly superior HDMI cables can make great improvements in imaging and sound quality.

WireWorld HDMI cables utilize unique designs specifically developed to minimize jitter by providing sharper, cleaner leading edges on the digital waveform. At each price level, they provide the lowest jitter available, producing distinct improvements in clarity, image focus, smoothness and dynamic contrast.
