Integrated Systems for Multimedia Processing

Goals

Our group of engineers has gained years of experience in mapping these solutions into successful low power VLSI products, with special emphasis on very low bit rate speech and video coding applications.

The goal of this research and development area is to investigate a wide range of possibilities in the implementation of powerful IP modules for the next generation of mobile multimedia terminals, in order to combine them into jointly optimized wireless multimedia systems. The research encompasses the development of novel and outstanding algorithms which permit maximizing the performance of commercial multimedia systems in terms of quality, bit-rate reduction and error protection.

Robust Video Compression

Motion estimation algorithms and architectures Flexible multi-standard architecture up to H.264 Novel low-cost image adaptive algorithms with unsurpassed levels of quality Rate-distortion optimization strategies Low power/area reduced pipelined systolic array architecture

There are two main constraints found in video communications, specially in the case of wireless applications: reduced bandwith and high bit error rates. This research program is devoted to overcome both drawbacks by developing:

Error protection strategies Motion compensated error-concealment techniques at the decoder Motion vectors recovery algorithms Channel coding by using turbo codes

Image, video and speech coding standards:• JPEG• JPEG2000• MPEG-2• MPEG-4• H.263, H. 263+, H. 263++ • H.264• G.726• G.729

New trends in personal computing are mainly focused on multimedia access and communication. Moreover, there is a great interest for portability in applications such as CMOS cameras, 3G mobile phones (UMTS) and personal digital assistants where the low-cost and low-power constraints are mandatory. For the particular case of mobile multimedia communications, it is expected to achieve an unprecedented growth and worldwide success in the next couple of years, with a potential market composed by millions of users around the world. Due to its mobile nature, good visual and hearing quality as well as reduced area/power dissipation are key factors for commercial products.
