With recent flourishing of embedded media applications such as MPEG-2,
H.264 and VC-1 encoders/decoders and wireless broadband communication
infrastructures such as 3G, WiMax and Wi-Fi, real-time multimedia
computing and communications on embedded systems becomes a major focus for
both software and hardware designers. In the first part of the talk, the
tradeoff between several design choices is analyzed, including the RISC
processor, the SIMD processor and the dedicated ASIC. Then, in the second
half of the talk, three emerging R&D efforts will be highlighted. First,
the design of a multi-format video codec to strike a balance between
flexibility and performance is addressed. This is motivated by the
observation that there are multiple audio/video compression formats to be
adopted currently. The trend of embedded processors is to support a wide
range of audio/video formats such as MPEG-2, H.264 and VC-1. The design of
multi-format codec demands a careful architecture consideration. Second,
we consider the design of low-complexity integrated encryption and
compression speech/video coding algorithms, which can significantly lower
the power consumption of mobile terminals for the digital rights
management (DRM). This gives an example of lower power design from an
algorithmic level. Third, the rate-distortion-complexity (RDC) optimized
video coding techniques are discussed. We emphasize a concept called
"decoding-friendly encoder design", where many computational heavy
operations can be saved at the decoder end while high visual quality can
still be preserved.
Biography of Dr. C.-C. Jay Kuo:
Dr. C.-C. Jay Kuo received the Ph.D. degrees from the Massachusetts
Institute of Technology in 1987. He is now with the University of Southern
California (USC) as Director of Signal and Image Processing Institute and
Professor of EE, CS and Mathematics. His research interests are in the
areas of digital media processing, multimedia compression, communication
and networking technologies, and embedded multimedia system design. Dr.
Kuo is a Fellow of IEEE and SPIE. He received the National Science
Foundation Young Investigator Award (NYI) and Presidential Faculty Fellow
(PFF) Award in 1992 and 1993, respectively. Dr. Kuo has guided 70
students to their Ph.D. degrees and supervised 15 postdoctoral research
fellows. Currently, his research group at USC consists around 40 Ph.D.
students (see website http://viola.usc.edu), which is one of the largest
academic research groups in multimedia technologies. He is a co-author of
about 800 technical publications in international conferences and journals
as well as seven books. Dr. Kuo is Editor-in-Chief for the Journal of
Visual Communication and Image Representation, and Editor for the Journal
of Information Science and Engineering and the RURASIP Journal of Applied
Signal Processing. He was on the Editorial Board of the IEEE Signal
Processing Magazine. He served as Associate Editor for IEEE Transactions
on Image Processing, IEEE Transactions on Circuits and Systems for Video
Technology and IEEE Transactions on Speech and Audio Processing.
