Abstract

A data distribution system is provided which generates outputs attribute data about multimedia data in advance and broadcasts the output attribute data together with the multimedia data so that the receiving terminal can grasp the outlines of the entire multimedia data and improve the visibility. A data broadcasting device (1) generates output attribute data about multimedia data in a data analyzing portion (13). The output attribute data exists alone or is embedded in the multimedia data. The multimedia data and the output attribute data are encoded in a protocol encoder (14) and broadcast from a transmitter (15). A receiving terminal device (2) receives the broadcast data in a tuner (21) and obtains the multimedia data and output attribute data in a tuner (21). When a data display portion (26) displays the obtained multimedia data, the output attribute data is referred to and information related to the multimedia data is displayed together with the multimedia data. A data analyzing portion (24) analyzes the multimedia data and extracts the output attribute data embedded therein.
