EXPERIENCE Graduate Student Researcher : (Jun 95 - Present) 
Video and Image Processing Lab, University of California, Berkeley.
Research, develop, and implement video compression and transmission systems for Internet unicast and multicast. Scope includes: 
  • Develop and implement error-resilient, rate-scalable, real-time video compression for Internet transmissions.
  • Develop and implement rate-based, TCP-friendly unicast protocols for Internet streaming.
  • Develop and implement a layered FEC framework to provide differential loss protection and bit-rate to different receivers in a multicast setting.
  • Analyze different methods of carrying MPEG compressed video over Differentiated Services networks.
  • Past work includes real-time issues of scalable video encoding/decoding.
