Network-friendly Multimedia Compression techniques

Recent technological advances in telecommunication,wireless networks and multimedia systems, and their convergence have enabled many narrow and broadband wireless-based mobile multimedia applications, such as exchange of multimedia data on PDA, pocket-PC and cell-phone. These applications demand new functionalities, such as scalability, content based manipulation, multimedia access tools, robustness in error prone environments and security. Moreover, the characteristics of mobile wireless communication links vary with respect to the time and position.

In multimedia wireless applications, source encoding, data transmission and network should work closely, in order to provide the desired QoS at the user-end. My research involves the design of error-resilient andnetwork-aware scalable multimedia compression techniques, to meet these challenges. I also consider the interactions among computational complexity, error resiliency and scalability features in a compressed bitstream for various wireless network-based applications. The focus is on MPEG-4, H.264/AVC, JSVM and JPEG2000 compression standards, MCTF and wavelet-based techniques.

Projects:

  • Robust Packetization of H.264 based Scalable Video Bitstream for Wireless Channels
  • Error Resiliency Schemes for H.264 Compressed Scalable Video for Wireless Networks
  • Scalable Video Compression techniques
  • JPEG2000, MPEG-4 and H264 Image/Video Compression Standards
