Bio: Ernest Tsui is a DTV architect and principal engineer in the Wireless Communications Architecture group in the Mobility Group at Intel Corporation. He is a senior member of the IEEE and a graduate of Cal Berkeley. He has also been involved in development universal QAM demodulators and managed a group that provided equipment to the Grand Alliance during the formulation of the ATSC DTV standard.

Title: DTV on Mobile Platform

Abstract: New usage models for watching Digital Television include watching while in trains, buses, cars, etc. on handheld devices with relatively low resolution video such as QVGA (320x240) or QCIF. However, watching high definition television (720p or 1080i) on a higher resolution displays like those available on notebook computers while mobile will be a challenge. Other challenges include co-existence with other wireless transmitters on the platform (e.g., like cellular, etc.), having adequate antenna orientations/architectures, meeting thermal requirements and finally having good battery life while watching DTV. We will address these challenges and describe some of the key components and the associated architectures in this presentation. We will focus on the DVB-T/H standard but the techniques are equally applicable to other COFDM based DTV standards around the world. The intended audience is architects, managers, and designers that want to learn about DTV architectures for mobile platforms.
