SM03 is an SD video input processor.


SM03 is an NTSC / PAL / SECAM video decoder and enhancer designed to produce high quality video images from noisy, low contrast and/or out of specification sources.


It is ideal for applications in the:


•Enhancement of noisy, low light images from security/CCTV/image-intensified cameras.

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

•Contrast enhancement of high dynamic range video such as CCTV, pipeline inspection or endoscope images.

•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.


The SM03 has applications in:


•Security/CCTV camera installations.

•Subsea/pipeline inspection.


•Remote video inspection.

•Vehicle cameras.

•Industrial imaging.
