Currently, there are seven TV channels available. Moreover, in parallel to the TV program, one-seg also provides data streams, such as program-associated information, news, traffic information, etc. Regarding movie content downloading and browsing services, au provides “EZ movie”, the “EZ channel” service and “Flash®” content. “EZ movie” allows the downloading of high-quality movie clips by mobile phone. The clip format conforms to the 3GPP2 and AMC format. 5 MB, or about 3 minutes in length. Users can view either downloaded or streaming movies.
5 MB, or about 3 minutes in length. Users can view either downloaded or streaming movies. QuickTime® supports the 3GPP2 format, so viewing or encoding of EZ movie content on a PC is possible. From a 1X WIN mobile terminal, KDDI (au) supports the 3GPP format in capturing video as well as the 3GPP2 format, ensuring interoperability with other carriers. Figure 2-12. EZ movie protocol stack Chapter 2. Mobile Internet Deployment in Japan 33 EZ Channel is a program distribution service enabling users to enjoy a variety of multimedia-heavy content (3 Mbps or less).
After selecting one or more people, the caller presses the Talk button again for immediate, simultaneous connection to the other users. The caller holds down the Talk button while speaking, then releases it to let someone else speak (while the Talk button is pressed, the speaker cannot hear others talk). One person can talk up to 30 seconds at a time. If nobody speaks for 30 seconds, the service is automatically disconnected. While connected, each user’s screen lists all participating members of the group and the current speaker.
