Abstract:

Bringing TV experience to the mobile users opens up a new era in the evolution of the mobile systems. Even if it started as a mere copying of the linear TV distribution of today, the mobile systems technologies that can provide feedback channels from every user enable new ways of enhancing the TV experience. So besides just watching TV via broadcast or on demand, a whole myriad of possibilities is enabled where the end-user can actively participate in the interactivity sessions with the content provider and indirectly with other viewers. Further, more sophisticated terminals enable pre-recording of the subscribed content to be consumed at the user's convinience.

Today, 3G wireless systems offer a superior streaming capabilities for TV distribution, either as unicast service (e.g. HSPA) or broadcast service (e.g. MBMS). Actually, the best utilization of the resources is provided with a combination of the unicast and broadcast services, where unicast part is used in areas with lower demand and for offering basically unlimited number of channels, while broadcast part is used as a capacity booster in areas where several users are interested in the same content.

There are also alternative pure broadcast technologies like DVB-H, DMB, ISDB-T and MediaFLO that are gaining traction in different parts of the world but to provide interactivity they must be integrated with some cellular system. That makes the Mobile TV market segmented for the time being but the near future will show what model is capable of gaining the largest momentum thus creating mass market for Mobile TV.

Biographical sketchs:

Dalibor Turina joined Ericsson Radio systems AB in 1993 as a member of the technical staff at the Access Networks research department. He has since been actively involved in the design and standardisation of the GPRS radio interface. In 1997, he became manager of the Air Interface Architecture unit at the Access Networks department of Ericsson Research. Between 2000 and 2003, he worked as en expert with system management strategic issues regarding Radio Access Network architecture at the development and business unit level. Since 2004, became a member of the corporate Group Function R&D Systems Management and responsible for Radio Access Networks architecture evolution. He holds an M.Sc. in telecommunications from the Faculty for Electrical Engineering and Computer Sciences at Zagreb University. (Author of 10 patents and 14 publications in the area.)

Thorsten Lohmar receives his diploma degree in electrical engineering from the University of Aachen (RWTH) in 1997. Beginning of 1998, he joined the Mobile Multimedia Networks Research Department of Ericsson Research in Germany and was working on various topics in the areas mobile communication systems such as Quality of Service, Hybrid networking and integrating WLAN into cellular environments. Since 2000, he is primarily focusing on mobile multicast and broadcast services. Thorsten led the "Mobile Multicast Protocols" workpackage of the IST-OverDRiVE Project (2002-2004). Since 2003, Thorsten is leading the Ericsson MBMS Standardization team and is actively contribution to MBMS standardization in 3GPP.
