VAST Video Audio Structure Text MultiMedia Browser is an interactive video library browser featuring tools for video search and retrieval, developed in the High Level Vision lab in the Department of Computer Science at Columbia University. The major parts of the browser include:

  • Text search tools for video content
  • Interactive visualization for video scene segmentation
  • Interactive visualization for filtered key phrases from automatically generated (ASR) transcripts (IBM ViaVoice)
  • Visualization for speaker segmentation
  • Streaming video (MPEG1) via a pure Java implementation that does NOT require a separate package such as JMF and does not rely on the underlying system codecs
