Description  - PDF Spec Sheet
The Model SDI 330 is a high quality random noise reduction processor utilizing Xintekvideo's
exclusive VIP technology. VIP (Video Improvement Processor) is a proprietary system that utilizes
recursive filtering techniques in conjunction with sophisticated motion compensation to achieve
outstanding noise reduction performance. The performance of the system is particularly startling
when applied to very noisy video signals. (Try using other noise reducers with very noisy pictures
and look at the artifacts generated by those processors).
The Model SDI 330 delivers over 9 dB's of S/N improvement for both luminance and color difference
signals. Independent control of luminance and color difference noise reduction permits processing
optimization for many types of random noise, e.g. plain "snow", color streaking, extraneous
interference and beats. Auto noise reduction permits hands free operation.
The SDI 330 is ideal for transmission links utilizing digital compression techniques (e.g. MPEG),
where random noise can severely affect compression efficiency. It is highly effective in video
production and post production applications to improve picture quality from poor tapes or old films.
The SDI 330 utilizes large gate array technology to deliver stable performance at an extremely
competitive price.
