Abstract:
An apparatus for generating a broadcast interoperable protocol (BIOP) message, comprising:a data/object carousel manager for periodically outputting cyclic data and transmitting the same upon receipt of a broadcast signal; a stream server for outputting audio/video data; and a remux unit for outputting remultiplexing data to a client upon receipt of the cyclic data and the audio/video data; wherein the data/object carousel manager includes a data message generating unit including: an IOR (interoperable object reference) generating unit for creating a list of objects upon receipt of objects in a tree structure, initializing the size of a current module in the created list, judging whether or not an object exists in the module, obtaining a module of a new size by adding the object size to the size of the current module, and generating an IOR to the object, a BIOP message generating unit for reading the list of objects having module control information and an IOR, allocating a memory for storing the module, judging whether or not an object exists in the module, and generating a BIOP message, and a block generating unit for dividing the modules generated by the BIOP message generating unit into blocks of the same size.
