mobiles  not media players yet  mobiles are not yet ready to be all-singing  all-dancing multimedia devices which will replace portable media players  say two reports.  despite moves to bring music download services to mobiles  people do not want to trade multimedia services with size and battery life  said jupiter. a separate study by gartner has also said real-time tv broadcasts to mobiles is  unlikely  in europe until 2007. technical issues and standards must be resolved first  said the report. batteries already have to cope with other services that operators offer  like video playback  video messaging  megapixel cameras and games amongst others. bringing music download services based on the success of computer-based download services will put more demands on battery life.  fifty percent of europeans said the size of a mobile was the most important factor when it came to choosing their phone  but more power demands tend to mean larger handsets.  mobile phone music services must not be positioned to compete with the pc music experience as the handsets are not yet ready   said thomas husson  mobile analyst at jupiter research.  mobile music services should be new and different  and enable operators to differentiate their brands and support third generation network launches.  other problems facing mobile music include limited storage on phones  compared to portable players which can hold up to 40gb of music. the mobile industry is keen to get into music downloading  after the success of apple s itunes  napster and other net music download services.  with phones getting smarter and more powerful  there are also demands to be able to watch tv on the move. in the us  services like tivo to go let people transfer pre-recorded tv content onto their phones. but  the gartner report on mobile tv broadcasting in europe suggests direct broadcasting will have to wait. currently  tv-like services  where clips are downloaded  are offered by several european operators  like italy s tim and 3. mobile tv will have to overcome several barriers before it is widely taken up though  said the report.  various standards and ways of getting tv signals to mobiles are being worked on globally. in europe  trials in berlin and helsinki are making use of terrestrial tv masts to broadcast compressed signals to handsets with extra receivers. a service from the norwegian broadcasting corporation lets people watch tv programmes on their mobiles 24 hours a day. the service uses 3gp technology  one of the standards for mobile tv. but at the end of 2004  the european telecommunications institute (etsi) formally adopted digital video broadcasting handheld (dvb-h) as the mobile tv broadcasting standard for europe. operators will be working on the standard as a way to bring real-time broadcasts to mobiles  as well as trying to overcome several other barriers. the cost and infrastructure needs to set up the services will need to be addressed. handsets also need to be able to work with the dvb-h standard. tv services will have to live up to the expectations of the digital tv generation too  which expects good quality images at low prices  according to analysts. people are also likely to be put off watching tv on such small screens  said gartner. digital video recorders  like europe s sky+ box  and video-on-demand services mean people have much more control over what tv they watch. as a result  people may see broadcasting straight to mobiles as taking away that control. more powerful smartphones like the xda ii  nokia 6600  sonyericsson p900 and the orange e200  offering web access  text and multimedia messaging  e-mail  calendar and gaming are becoming increasingly common. a report by analysts instat/mdr has predicted that smartphone shipments will grow by 44% over the next five years. it says that smartphones will make up 117 million out of 833 million handsets shipped globally by 2009.
