Picture optimizing: SDI vs. DVI & HDMI
Which digital interface delivers the “best” picture?
Martinsried, January 18 2005: Brilliant picture quality in the fully digital home cinema is not only determined by single hardware components, but especially by the interfaces linking the devices.
In the video picture optimizing environment there are significant differences in regards to digital interfaces, which make the often overestimated call for DVI/HDMI inputs for high end video scalers appeal bizarre: DVI and/or HDMI outputs of DVD players by nature always distribute an already processed, “partially” optimized video signal (e.g. 480/576 progressive). The result: The capacity of a video scaler will only be used to a certain extent or in a limited way as the delivered picture material is “manipulated” and the video scaler can not completely bring its potential for quality enhancement into operation.
In comparison to that a SDI output, standard in professional video and studio technology, integrated into a DVD player delivers a completely “raw” signal in loss-free quality to the video scaler for further processing. All video processing levels of a professional scaler such as the picture optimizer plus II SDI can deliver their full performance and brilliant picture quality with a SDI signal, as they get the “raw”, unprocessed DVD data stream as a basis.
SDI for the time being is the only standard digital input signal able to deliver a genuine 1:1 rendition of DVD content. Reason enough for cinemateq, to integrate this standard in the strategic context of the “fully digital chain in home cinema “ also for the future.
