Peer-to-Peer
Technology and Its Applications
Yang Guo and Christoph Neumann
Thomson Corporate Research
|
|
| |
|
Peer-to-peer technology has attracted a lot of attention
from academia, industry, as well as the general
public since its inception. Peers in p2p network
are implemented with both server and client functionality,
thus bringing computational as well as storage resources
into the system and improving the overall system
scalability. P2P applications such as file sharing,
VoIP, etc. have become disruptive Internet applications
that attract a large number of users and account
for a significant chunk of Internet traffic. The
legal fights between content owners, users, and
p2p software developers over copyright issues ignite
more debates. The recent new direction of content
owners attempting to use p2p technology to reduce
the delivery cost in order to compete with illegal
downloading adds one more dimension to the story.
In this tutorial, we cover the major developments
of p2p technology over the past five years. The
tutorial consists of three parts. In the first part,
we start with the history and motivation behind
the development of p2p technology. We then describe
the classical p2p technologies such as application-level
multicast, un-structured p2p networks, and structured
p2p networks, and compare and contrast these different
technologies in terms of performance, scalability,
and complexity. In the second part of the tutorial,
we present in detail several popular p2p applications,
such as Skype (p2p Voice over IP), BitTorrent (p2p
file sharing), and p2p live streaming (EMS, coolstreaming,
etc.). We also introduce emerging p2p video-on-demand
(VoD) services. In the third part of the tutorial,
we look into the future of p2p technology. We pay
special attention to the use of p2p in commercial
applications. We discuss if p2p can be used for
profit-centered commercial applications, and what
are the potential issues and challenges. The tutorial
is wrapped up with interactive discussion and question
and answer session.

Protection and Digital Rights Management
Willem Jonker
Philips Research
|
|
|
|
DRM (Digital Rights Management) is seen as a very
important enabler for all kinds of content delivery
services. With the growing communication and processing
abilities of consumer devices, DRM comes within
reach of the consumer. Important initial initiatives
are around EMD (Electronic Music Distribution)
and the emerging downloading of digital content
to home networks via broadband connections and
to mobile devices by means of GPRS and UMTS. As
a result the combined IT, CE, and Telecom industry
is taking up DRM very seriously and is investing
in the realization of DRM solutions, amongst others
in standardization fora like MPEG, DVB and OMA.
The tutorial will consist of three parts: - Business
models and stakeholders - Enabling technologies
and products - Standardization activities. The
part on business models and stakeholders will
address various DRM business models centered around
digitial content delivery, interactive TV, and
mobile services. In addition, it will discuss
the roles and interests of various stakeholders
such as content providers, services providers,
DRM solution providers, etc. Finally, it will
discuss some emerging services such as for example
PressPlay and MovieLink.
The part on enabling technologies will address
base technologies for the realization of DRM systems
such as cryptography, key management, watermarking,
and content identification technologies. In addition,
it will discuss a number of existing products.
The part on standardization will address the main
standardization activities amongst others going
on in MPEG-21, DVB-CPT, and OMA.

Perceived
Motion Blur and Sharpness in Liquid Crystal Television
Scott Daly
Sharp Labs |
|
|
|
This tutorial will begin by covering the basics
of Liquid Crystal Displays (LCDs) and in particular
their application toward television, referred to
as LCTV. After setting the foundation for several
dimensions of image quality such as spatial, color,
temporal, and dynamic range, as well as the corresponding
human visual system capabilities along those dimensions,
the tutorial will focus in on the main problem that
has hindered the LCTV: motion.
Since their introduction, LCDs were known for having
a slower and asymmetrical temporal response compared
to CRTs, which led to motion blur and flicker, respectively.
For many years this hindered the use of LCD technology
for television. Improving the Liquid Crystal response
time and the use of digital overdrive techniques
led to a substantial reduction in motion blur, enabling
the LCTV (Liquid Crystal Television). Still, some
residual blur was visible in panned textures and
scrolling text. Further analysis considering human
visual system smooth pursuit eye tracking combined
with the hold-type temporal aperture used with LCTV
has identified the remaining sources of blur. New
techniques that are appearing in prototypes such
as backlight flashing, black data insertion, and
frame rate conversion reduce the motion blur to
that of CRT levels. However, the CRT is not necessarily
the ultimate benchmark, as it suffers from other
motion artifacts, especially with slow velocities.
This talk will describe the key spatiotemporal properties
of the visual system relevant to motion blur, and
the various approaches used in LCTV technology toward
improving overall moving picture sharpness.

Residential
DSL Standards
Jalil Kamali

As late as only a decade ago, the use of phone lines
for broadband communication was perceived by most
experts as unreliable, expensive, and inefficient.
It turns out, however, that what was originally
planned to carry 4KHz voice signal can be utilized
at much higher frequencies, providing reliable full
duplex broadband access at rates up to 100Mbps symmetric
to hundreds of millions of residential and business
customers, making DSL the number one broadband access
technology worldwide. Many factors contributed to
this breakthrough in broadband technology. On the
technical side one can point to advanced signal
processing schemes and highly integrated analog
and digital circuit design. At the same time appropriate
regulatory policies as well as a set of comprehensive
and widely accepted standard recommendations significantly
helped the new technology to find its way into the
marketplace and to be massively deployed. The history
of broadband communication proves that a solid and
well consented standard recommendation has a key
role in promoting the underlying technology and
DSL standardization is undoubtedly one of its perfect
examples.
This presentation starts with a general introduction
to DSL; its preceding technologies, its challenges,
its competition, etc. We will then look back at
the first standard bodies which got involved in
developing regional specifications for the DSL transceivers
and how they were eventually assembled under one
umbrella in the International Telecommunication
Union (ITU). We will further review different recommendations
created by the ITU over the years in response to
dynamic market requirements. The basic features
of each recommendation will be covered at a reasonable
technical level.
To complete the picture, the activities of other
DSL oriented standard bodies such as the DSL Forum
or regional committees like NIPP-NAI, ETSI, and
TTC are also discussed.

Recent
Developments in Video Compression Standards: from
Scalable to Multi-view Video Coding
Bart Masschelein

In March 2003, the Joint Video Team (JVT), a collaboration
between ITU-T VCEG and ISO/IEC MPEG, finalized a
new video compression standard called H.264/Advanced
Video Coding (AVC). Next to improving compression
efficiency performance (up to 50% of bit-rate saving
over previous standards), H.264/AVC provides a network-friendly
video representation for applications such as video
telephony, storage, broadcast and streaming.
Because of the improved compression efficiency and
flexibility of the core coding technologies introduced
by this new standard, extensions of H.264/AVC are
currently being developed by the JVT. The Scalable
Video Codec (SVC) extends H.264/AVC with scalability
features at the bit-stream level. Beside temporal
scalability, which was already possible with H.264/AVC,
SVC supports (non-)dyadic spatial and quality scalability.
The latter can be either at a coarse level, or at
a fine granular level, allowing for an embedded
bit-stream. Another H.264/AVC extension under development
by JVT is the Multi-view Video Coding (MVC). MVC
is an encoding framework for multiple video streams
and associated camera parameters, and address the
request of a large number of companies for a standard
that enable Free Viewpoint Television (FTV) and
3D Television (3DTV).
After a short overview of the MPEG and ITU-T standardization
bodies and previous standards, the tutorial focuses
on the above mentioned extensions of H.264/AVC,
which will be standardized as amendments to MPEG-4
Part 10. A technical review of the Scalable Video
Coding (SVC), expected to be finalized by early
2007, is presented. In addition, the challenges
posed by implementing this new standard are highlighted.
Examples of target applications are provided as
well. Then, the current status of the Multi-view
Video Coding (MVC) is reviewed. Finally, application
scenarios of this extension, expected to be finalized
in early 2008, are presented and discussed. This
tutorial provides an overview on these emerging
standards and on their impact on consumer electronics,
thus allowing the audience to understand their added
value without un-necessary technical details and
mathematical formulas. Also, functionalities and
performance are shown using (self-)explanatory figures,
thus appealing to a wider audience.
