Mobile Video Compression
Prof. Fernando Pereira
Summary
All available video coding standards have adopted with great success the predictive video coding approach, allowing to largely deploying services and products such as digital television, DVDs, Internet streaming and mobile multimedia. From the MPEG-1 Video, MPEG-2 Video and MPEG-4 Visual standards to the more recent H.264/AVC (Advanced Video Coding), Scalable Video Coding and Multiview Video Coding standards, efficient spatial and temporal prediction tools have been at the basis of the continuous developments and gains in video compression.
Around 2002, a new video coding paradigm has emerged, the so-called distributed video coding (DVC). This coding paradigm avoids the computationally intensive temporal prediction loop at the encoder, by shifting the exploitation of the temporal redundancy at the decoder. This approach, still maturing, may bring significant advantages for a large range of emerging applications, including wireless video cameras, wireless low-power surveillance, videoconferencing with mobile devices, and visual sensor networks.
Though video compression has been steadily evolving in the past 20 years with significant developments in the technology, major compression gains, impressive deployment of services and applications, and an amazing overall impact on our society, something seems to have changed recently since, after the development of the very successful H.264/AVC standard, further compression gains have been short and more difficult to reach than usual. This fact led many video compression research experts to announce the end of the video compression saga as known from the past two decades.
This tutorial intends to present the most important recent achievements on video compression, within and outside standardization bodies, and discuss future needs, trends and technologies with especial emphasis on mobile environments. The tutorial is intended for researchers, professionals and students in the area of video compression and applications, especially those with interest in learning about recent developments and future trends in mobile video compression standardization and research.
