SM03 is an NTSC/PAL Video Enhancer and Synchroniser.


SM03 is an NTSC or PAL video decoder, noise reducer and synchroniser designed to produce high quality video images from jittery, noisy and/or out of specification sources.



It is ideal for applications in the:


Improved viewing of legacy NTSC and PAL video sources such as Laserdisc.

Recovery of analogue tape and video disc video for archiving and transfer to modern media.

Very low artefact decoding and noise reduction for MPEG encoding pre-processing (reduces compressed bandwidth requirement by up to 20% compared with conventional decoders).

Broadcast quality decoding of composite video images.
