Multimedia Applications: Protocol MOT



To transport media in digital broadcasting channels independent of their individual characteristics (address, type, capacity, etc.) in DAB radio, a uniform system of transportation of multimedia objects was introduced. It is the Multimedia Object Transfer (MOT) protocol. Objects MOT play the role of universal capsules allowing to transmit any media via DAB channel and – after being transported to the receiver – to use their own parameters to unpack, merge in the radio buffer, decode, and display.

Each object MOT consists of a header containing information about the object and the field locating transmitted object. Due to the nature of a broadcast system, the header and object field are transmitted independently. In order to quickly organize the object reception, the user should have the shortest possible time to access offer of broadcasted programs and services after turning on the receiver. So, the header is transmitted more frequently than the media objects themselves.

The MOT protocol may be used for the transmission of slides, video, MOT directory, broadcasting websites, or electronic program guide.
