Mobile Phones As Multiple Information Terminals: from the Research Project “People and Media Usage in Japan”
Mobile Phones as Multiple Information Terminals: From the Research Project “People and Media Usage in Japan” SUZUKI Yuji, YONEKURA Ritsu, NAKANO Sachiko, and NISHIMURA Noriko This is a summary and analysis of a survey on trends in mobile phone use conducted in November 2006.1 Mobile phone use in Japan rose rapidly from the late 1990s, with the number of subscribers reaching over 60 million by 2001, greater than the number of landline subscribers. As of February 2007, there were 95.76 million subscribers, and, added to the 4.91 million PHS sub- scribers, the total figure rose well over 100 million.2 According to these fig- ures, we have entered the “one mobile phone per person” era. Research by the Ministry of Internal Affairs and Communication shows that in 2006, there were more people using the Internet on mobile phones and PHS than those using the Internet on their computers (PCs).3 The mobile phone is becoming a major information terminal through which people access the Internet. As seen in Internet use, mobile phones have achieved rapid upgrades and functional diversity. In addition to standard communication functions such as making phone calls and sending e-mail, others such as web searches, music downloading, cameras, games, calendars, calculators, 1seg (one-segment; mobile digital terrestrial television broadcasting service) reception, video reception, and electronic payments for Internet shopping have become the focus of increasing attention. This shift has become more pronounced with the spread of 3G (third-generation) mobile phones, which make possible high- speed, high-volume data transmission. As such, mobile phones have increas- ingly become “multiple information terminals” used in every imaginable situation in daily life. -

Mobile TV Technologies Zahid Ghadialy March 2006 © 2006 Zahid Ghadialy What is Mobile TV Mobile TV Broadcasting allows the user to watch their favourite TV programs such as dramas, news, music, sports and documentaries on their mobile device. The service works by receiving a specialised digital TV broadcast signal from the air in much the same way as televisions at home will do in future. Channel guides will also be broadcast allowing users to keep abreast of the latest programs on air. It is not the same as a streaming video service over 3G or GPRS, but one which is optimised for longer period TV viewing by large numbers of simultaneous users with high picture quality and low battery power consumption.
