PAD INTERLOCKING TYPE TRANSMISSION METHOD FOR DMB PAD BROADCASTING

摘要

A PAD(Program Associated Data) interworking transmission method in a terrestrial DMB(Digital Multimedia Broadcasting) PAD broadcast is provided to perform an interworking service of the terrestrial DMB PAD broadcast and re-search and link received storing PAD data by inserting additional information except for a photo into photo data in case of a slide show service, synchronizing and connecting the photo data with NPAD(Non PAD), setting and connecting link data with the Internet. An automatic data transmission system prepares photo data necessary for transmitting a PAD broadcast, checks a header of the photo, parses an internal structure of the photo, and obtains sizes of the header and a place where a real photo is located. The automatic data transmission system obtains data to be added from a database of a broadcasting data database system, generates data according to a specific protocol, adds the generated data structure to the photo, and generates one photo. A PAD transmission system transmits the generated photo as a captured photo of a text image to an encoder. The encoder parses the received data into a photo and data by the specific protocol, and interworks and displays the data associated with the photo.
