The Mobile TV is a new telecommunications device that allows individuals to view current television broadcasts instantly on their mobile phone. Nokia is working with telecommunications, media, and broadcasting to create the Mobile TV, which is driven by the DVB-H technology. The DVB-H combines conventional digital video with Internet Protocol to produce a smaller image for the smaller device. The content from broadcasters is sent to the user’s mobile phone through an IP Datacast System. The Mobile TV can benefit broadcast network operators, mobile network operations, broadcasters, and people who just want convenient entertainment.

Nokia has introduced the Mobile TV device to pilots in Finland, Germany, Australia, France, Netherlands, Spain, and the UK. The Mobile TV utilizes the technology of DVB-H, Digital Video Broadcast-Handheld. DVB-H is beneficial compared older broadcast delivery systems because it provides an excellent picture and audio quality, reduces battery consumption by up to 90%, and allows up to 55 mobile channels. The content from broadcasters, aggregators, and content providers is carried by broadcast network operators to the mobile network operators which displays the picture on a cellular phone. IP (Internet Protocol) Datacast uses IP to distribute digital content to mass audiences. IP is the format in which content is distributed over the internet, and this content is expedited in the form of data packets.

Network structure makes effective us of high bandwidth channels with fast transmission speeds. This gives mobile phone consumers the ability to view a wide selection of TV services. Standardization creates the grounds for a horizontal market so consumers can choose from a wide variation of suppliers and services. “Mobile TV enables expansion of broadcast business into viewers’ mobile lives and offers new revenue streams such as advertising and subscriptions.”

Mobile TV provides a positive correlation between mobile network operators, expanding TV coverage, and revenues for broadcast network operators. With people living mobile lifestyles, the Mobile TV provides a convenient form of entertainment for them, but also generates revenues for businesses who participate in advertising and subscriptions. The Mobile TV is digital instead of analog which will generate new growth from investments.

When offering broadcast services to consumers, mobile network operators play an important role. Mobile TV offers an easy to understand device and a quick connection time for customers on the go. This device also can connect with customers using affiliate programming for a one-to-many broadcasting service.

Broadcasters benefit from the Mobile TV because it takes television into any place possible with a wireless connection—the park, on a bus, or on a bike. The Mobile TV expands the customer range as well as the prime time for television shows. People will now start watching TV on their way home at 5 o’clock instead of when they get home at 7 o’clock. There is a Mobile TV application for the selection, purchase, consumption, and storage of TV programs, and the TV offers up to 4 hours of watch time. The mobile TV is different from regular television viewing in that a viewer can select and purchase items on TV, follow embedded links to the internet, and can interact with programming by SMS voting or chatting.

Mobile television provides a new platform for individuals to catch up with information and entertainment while on the go. “More than 2 billion people around the world own or use mobile phones. And increasingly, consumers are using their mobile phones for multimedia—not just for communication, but also for entertainment, news, and information services.”
