This books presents the research work of COST 273 Towards Mobile Broadband multimedia
Networks, hence, it reports on the work performed and on the results achieved within the project
by its participants. The material presented here corresponds to the results obtained in four years
of collaborative work by more than 350 researchers from 137 institutions (universities, operators,
manufacturers, regulators, independent laboratories and others – a full list is provided in Appendix
B) belonging to 29 countries (mainly European, but also from Asia and North America) in the area of
mobileradio. Theobjectiveofpublishingtheseresultsasabookisessentiallytomakethemavailable
to an audience wider than the project. In fact, it just follows a ‘tradition’ of previous COST Actions
in this area of telecommunications, i.e. COST 207, 231 and 259.
Mobile multimedia communication is increasingly in demand because of the basic need to communi-
cate at any time, anywhere, using any technology. In addition, to voice communication, people have a
desire to access a range of other services that comprise multimedia elements—text, image, animation,
high fidelity audio and video using mobile communication networks. To meet these demands, mobile
communication technologies has evolved from analog to digital, and the networks have passed through
a number of generations from first generation (1G) to fourth generation (4G).
In case you haven’t noticed, multimedia communication over IP and wireless net-
works is exploding. Applications such as BitTorrent, used primarily for video
downloads, now take up the lion’s share of all traffic on the Internet. Music file
sharing, once on the legal cutting edge of massive copyright infringement on col-
lege campuses around the world, has moved into the mainstream with signifi-
cant legal downloads of music and video to devices such as the iPod and nu-
merous other portable media players.
The TW9910 is a multi-standard video decoder and encoder chip that is designed for
multimedia applications. It uses the mixed-signal 1.8V CMOS technology to provide a low-
power integrated solution.

The high defi nition multimedia interface (HDMI) is fastbecoming the de facto standard for passing digitalaudio and video data in home entertainment systems.This standard includes an I2C type bus called a displaydata channel (DDC) that is used to pass extended digitalinterface data (EDID) from the sinkdevice (such as adigital TV) to the source device (such as a digital A/Vreceiver). EDID includes vital information on the digitaldata formats that the sink device can accept. The HDMIspecifi cation requires that devices have less than 50pFof input capacitance on their DDC bus lines, which canbe very diffi cult to meet. The LTC®4300A’s capacitancebuffering feature allows devices to pass the HDMI DDCinput capacitance compliance test with ease.
