  • Wavelet video coding basic research: recognizing deficiencies of current video compression schemes
  • Better MPEG support for non-PC platforms
    • joint project with North Valley Research
    • early adopter of SGI's MediaBase architecture
  • Contents generation: MPEG to H.263 re-encoder completed
