Digital video broadcasting – handheld (DVB-H) refers to the broadcasting of digital video on handheld devices such as mobile handsets, personal digital assistants (PDAs) or other handheld, battery-powered devices. DVB-H is an extended format of DVB-T, which is TV broadcast through terrestrial transmissions.
Television and digital video broadcasting have become a basic necessity in both residential and professional life. Digital video broadcasting is a service suite used for video transmission through different modes and mediums.
DVB-H terminology focuses on using the smallest amount of resources to provide the best possible service. The technology used to ensure successful DVB-H processing is known as time slicing, where data packets (IP datagrams) are transmitted as data bursts in small time slots. This concept is also known as buffering, because users are able to watch mobile TV on mobile handsets or other handheld devices while the video is continuously buffered on the other end.
Enormous development in mobile devices and PDAs has allowed TV and video service providers to provide transmission to mobile users. DVB-H is generally considered to be the technology that allows users to watch digital video independent of telecommunications service providers.
