چکیده
Due to rapid growth of using mobile phones, this device becomes a part of todays humans life using it for many applications from a simple camera, MP3 player, FM radio to now mobile TV. Technology has shifted the handset from a simple calling and answering device to being a part of an advanced entertainment, Internet access, gaming, office application, mobile commerce and utility device. Mobile TV is a very important tool for live TV and many useful applications like, videoconferencing, video file sharing and group working. Generally the transmission of TV programs or video for a range of wireless devices is called mobile TV. The programs can be transmitted in a broadcast mode, multicast and even unicast mode to be delivered to a user on demand. The mobile TV transmissions can be via the terrestrial medium or delivered via high-powered satellites directly to mobiles. DVB-H is a mobile TV technology that is an extension of digital video terrestrial technology or DVBT [Broadcasting 2009]. DVB-H launched after a series of successful trials in Pittsburgh, Barcelona, Oxford [Protection 2006], and other sites that proved they could bring digital video broadcasting to millions of handhelds under a new technology[Elisa et al. ]. Other mobile TV technologies like 3G oprators in the United States of America, Japan, and Europe had been offerd streaming video services and live TV as well. In South Korea services using digital multimedia broadcasting technologies and in Japan the 3G FOMA services began in 2005 and 2002. Mobile TV application of the handsets has been tested in several situations in recent years. Telenor Norway, for example, had broadcast the 2005 Winter Olympics held in Torino live, along with the highlights and other features, for mobile users on 3G networks [TV et al. ]. When the FIFA games started in Germany in June 2006, the towering TV transmitters of Berlin, Munich, Frankfurt, Rome, and Milan [TV et al. ], as well as a number of
