HARVARD VLSI GROUP

Ultra Low Bandwidth Video Coder/Decoder

Graduate Student: Sang Hoon Hong

Faculty Advisor: Woodward Yang

Video coding for low bandwidth channels requires high compression ratio and usually low image resolution. Many video compression systems use transform coding based video coders. The main algorithm or standard in the field of ultra low bandwidth is H.263. It is very similar to the MPEG standards. These standards, however, may not be optimal for VLSI implementations. Especially for low-power and compact environments such as a mobile video phone or a one-chip camera with video compression.

We are investigating in methods that could be more suitable for VLSI implementations. In particular, we are looking in the form of vector quantization.
