Abstract:

This tutorial will provide an introduction to human interface with emphasis on human factors as applied to consumer electronics devices. The session will provide an overview of how to approach product design with people in mind. Human factors and ergonomics are concerned with adapting products to people, with the objective of improving the overall systems performance involving human and product elements. We are all familiar with the problems people have operating consumer products, like the video tape recorders, set top boxes, washing machines, telephones and other home products. " This tutorial will look at ergonomics methods in consumer product design and evaluation. This section will include a review of some popular methods which will be used to evaluate a device. It will show how to start an evaluation of a product, the processes involved and the outputs generated. " The next section will provide an overview of systems analysis of consumer products. This will include human error identification, and task analysis for error identification (TAFEI). " Then design issues of hand operated devices will covered. It will include issues related to design principles of consumer electronic products. The tutorial will provide opportunity for student interaction and hand outs will be available that cover some design guidelines.

Abstract

This tutorial will give a historic overview of the evolution of audio/video processing in television including an outlook on the growth of media processing requirements in the coming years. It will address some of the key architectural parameters of media processing like data rates, required processing power and memory bandwidth. Also a short overview will be given of the interfaces in a television system and their main characteristics.

In the codec section, we will address various audio/video codec standards (e.g. h.264, avs, mpg4, mp3, aac etc.) and their architectural considerations. One view we will present is the implementation flexibility for future requirements versus the cost-effectiveness. Another topic we will discuss is the embedding of the codec subsystem in a larger SoC, We focus here on the interaction with the memory controller, on minimizing memory traffic and on techniques to reach latency tolerance in the overall system.

In the video and audio post-processing parts we will address the trade-off between on-chip vs. off-chip memory bandwidth and its relation to fifo and cache implementations. Next to that, we will address and discuss benefits and drawbacks of programmable vs. dedicated hardware solutions. On the video post-processing side, we will especially give attention to the important aspect of motion-based processing. The motion based processing, e.g. frame rate conversion is typically a high-performance requiring sub-system, in which the various architectural trade-offs are relevant.

He received the Diploma degree in electrical engineering and the Ph.D degree, in 1988 and 1994 respectively, from the University of Hannover, Hannover, Germany. From 1988 to 1994 he was a Research Assistant with the Information Technology Laboratory, University of Hannover. In 1994, he joined Philips Semiconductors resp. NXP Semiconductors, Hamburg, starting at system and algorithm pre-development. Since 2000 he is working on TV system definition and implementation.

Johan Janssen graduated in electrical engineering at the Eindhoven University of Technology in 1993. In 1994, he joined Philips Research Labarotories Eindhoven, the Netherlands, and became a member of the TV system Department. In 1998, he moved to Philips Research Briarcliff, NY. During his research period, he led various research projects related to video enhancement. In addition, he was responsible for defining various high-end TV signal processing functions and their architectural requirements. In 2002, he joined Philips Semiconductors. Within NXP, he is currently responsible for the architecture definition of Video and Media subsystem solutions for the various semiconductor markets. He has authored and co-authored many papers and holds more than 15 patents.
