Tutorial#: T3
Title: "Introduction to UPnP"
Presenter: Jack Weast (co-author of the book "UPnP: Design By Example")

Abstract:
I believe networked devices should be as easy for consumers to set up as stereo equipment - when you plug it in and turn it on, it just works. Universal Plug and Play technology can help make this happen. UPnP devices will provide new levels of automation and ease of use and will enable new usage models in the home and small office. Imagine being able to use your home PC as a control center from which you can direct audio or video content (music, movies, and so on) from the Internet or your hard drive to play on your stereo or TV. Or imagine sitting on your couch with friends and family viewing your latest vacation pictures on your TV - a slide show streamed directly from your PC. Digital content, broadband access, and wired and wireless home networks are ushering in a new digital media age that will make such things possible.

The tutorial is intended for technical professionals - those who just want to understand UpnP and those that also must implement UPnP devices. It provides a detailed look into the various protocols that comprise UPnP, including GENA, SOAP, SSDP, and Auto-IP. During the tutorial I'll walk attendees through the development of a fully functional UPnP device, a "Super Toaster" and corresponding controlling application. At each step, we'll cover the theory behind each protocol and the code needed to implement it. Attendees should be familiar with the C programming language and basic network programming concepts and protocols. I'll provide a CD-ROM of course materials (PDF files of course slides, software, etc).

Biography:
Jack Weast is a senior software engineer at Intel Corporation and leads the development of UPnP-based devices for media distribution within the "Digital Home." Jack's work has ranged from solving laptop power management and mobility issues to developing Bluetooth and Intel XScale-based embedded Linux devices. As a developer involved with emerging technologies that extend the PC's role in the home, Jack has spoken at a variety of events, including the Intel Developer Forum.

Tutorial#: T4
Title: "Concepts, Technologies, Systems and Applications for Online Entertainment"
Presenter: Prof. Dr. Marco Roccetti, Prof. Dr. Paola Salomoni (both University of Bologna, Italy)

Abstract:
On-line entertainment technology is becoming a serious business. Jesse Schell, senior scientist at the Entertainment Technology Center of CMU, reports that in 2002 U.S. consumers spent $9.4 billions on game software and devices - yet again surpassing the revenues provided by the movie industry. Microsoft alone says it will spend $2 billions over the next years to establish its Xbox machine and online game play.

On the other side, perhaps no other device symbolizes Silicon Valley's shift to digital on-line entertainment better than the iPod. Its hip design and ease of use have rapidly drove this device to the top of the MP3 player market, especially when Apple has made it compatible with both Macintosh and Microsoft Windows-based PCs. Several analysts report that the introduction of the iTunes Music Store service in 2003 has propelled the iPod to a shipment of 807,000 units during the last quarter of 2003, thus yielding a record share of almost 20% in the MP3 player market.

In some sense, the iPod is the symbol of the PC industry's shift to focus on the consumer world. The case of the success of such popular personal portable audio device (linked with the Internet) is a prominent warning of an impending technological novelty we are all beginning to experience. Based on the ever-growing popularity of the Internet, the today's entertainment technology is going to create a large interactive environment for the delivery of the maximum entertainment value to millions of consumers worldwide. Those (virtual) entertainment spaces amount to worlds where games, movies, songs, plus news, sport events and shows, are all made available for instant enjoyment with just one click.

While in the past computer-mediated digital technologies offered predominantly passive experiences (e.g., video on demand), modern, high-tech, on-line entertainment is taking advantage of a series of radical innovations in the field of wireless/wired communications that are making ever-new nomadic entertainment experiences possible. In this respect, what was meant with the term entertainment technology as recently as a year ago requires a continual redefinition in light of recent advances in network and computer technologies. Further, all these technological advances have been raising a set of interesting research questions that concern the provision of networking and system support to entertainment: How can the Internet can take the lead of this complex scenario for scaling the delivery of entertainment contents to millions of users? How can digital entertainment be delivered effectively to very small devices? How can a greater interactivity be implemented for enabling consumers to enjoy more exciting experiences while on the move?

This tutorial provides an opportunity for researchers, engineers and academia to disseminate the latest technical information and research findings on concepts, technologies, systems, and applications for on-line digital entertainment covering existing deployments, current developments and future evolution.

Tutorial#: T6
Title: "Wearable Systems: Intelligent, Any Time Any Place Information Gateways"
Presenter: Prof. Dr. Paul Lukowicz (ETH Zürich, Switzerland; University of Health Informatics and Technology Innsbrück, Austria)

Abstract:
Wearable technology is widely believed to be crucial for the next generation of mobile consumer systems and is being actively pushed by many major players in the consumer electronic and communications field (e.g Infineon, Phillips). Wearable systems can be broadly defined as mobile electronic devices that can be unobtrusively embedded in the user's outfit as part of the clothing or an accessory. In particular, unlike conventional mobile systems, they can be operational and accessed without or with very little hindrance to user activity. To this end they are able to model and recognize user activity, state, and the surrounding situation: a property, referred to as context sensitivity. Wearable systems range from micro sensors seamlessly integrated in textiles through consumer electronics embedded in fashionable clothes and computerized watches to belt worn PCs with a head mounted display.

The tutorial will describe how wearable computing concepts can change network access possibilities, consumer habits and usage patterns. It will introduce concepts of context recognition driven information retrieval and recording. Ideas, technology trends, and potential applications will be described and the impact on connectivity requirements analyzed. The tutorial will focus on an overview of wearable technology and its implication for networked mobile consumer products. It will also provide the participants with the hands on experience with different experimental devices and technologies.

Tutorial#: T8
Title: "Networked Appliances - What They Are, How They Work and Challenges to Adoption"
Presenter: Stan Moyer (Telcordia Technologies, NJ, USA)

Abstract:
As computing power becomes more ubiquitous we can reasonably expect it to move from desktop behemoths down to the individual gadgets that already fill our lives - the networked toaster has long been used as an example of the kind of device that might receive network functionality in the fullness of time, but prior to that the TV Remote, the HiFi or the Central Heating/Air Conditioning systems are all better candidates for the addition of network functionality.

While the utility of adding a network connection to a toaster might reasonably be called into question there could be significant advantages from having many devices in your home connected together - burglar alarms that can use your house lighting system, home entertainment systems that can co-ordinate with your curtains or perhaps something as simple as being able to query the electricity, water or gas consumption of your home and the devices in it are all interesting and compelling applications of this kind of technology.

This tutorial will answer the question of what is a Networked Appliance and will go on to give use cases and practical examples of where we might typically expect to find them. It will then go on to discuss the constraints and capabilities of the early devices that we see in the market today, highlighting the limitations of the technology that is available. It will then discuss the work that is progressing to address some of these limitations in many fora including the OSGi, IETF and other places, with specific examples of how technologies such as SIP for Appliances can be applied to the problems we foresee before concluding with a vision of a possible future with multiple, integrated, devices in heterogeneous network environment communicating and interworking seamlessly with the other devices around them.

Tutorial#: T9
Title: "IP Header Compression Enabling High Quality Consumer-Oriented Communications"
Presenter: Prof. Dr. Frank Fitzek, Prof. Dr. Tatiana K. Madsen (both Aalborg University, Denmark)

Abstract:
As new services and protocols emerge for wired networks, the need to incorporate those services and protocols in the wireless environment arises to break new ground in consumer electronics. To fulfill bandwidth constraints of wireless scenarios, the compression of the packet traffic is required. This can be done by header compression mechanisms that reduce the amount of overhead information. Many header compression schemes exist already, but most of them are not suitable for the wireless environment. Wireless links have typically a very high and variable bit error probability (BEP) due to shadow- and multi-path fading and mobility. Compression schemes designed to operate in error-prone environments can reduce the required bandwidth, and improve the latency and Packet Error Probability (PEP). The goal of the tutorial is to explain why IP header compression is needed in the consumer field and its methodology.

The tutorial gives a broad overview of header compression schemes, while presenting in-depth study of RObust Header Compression (ROHC), a scheme developed for wireless channels. The intended audience for this tutorial includes network managers, application designers, and others who are considering implementing or dealing with header compression schemes. This includes persons at sites planning networks.
