Abstract: PURPOSE: A device and a method for inserting synchronizing data for digital data broadcasting are provided to reproduce a synchronizing data at a receiving part before its reproducing time by properly inserting the data to MPEG-2 video/audio transmission stream, thereby providing the synchronizing data service in real time. CONSTITUTION: A device for inserting synchronizing data for digital data broadcasting includes a synchronizing data selecting/managing part(410), an additional data storing part(420), a transmission stream analyzing part(430), a synchronizing data inserting/managing part(440), a reproducing time resetting part(450), and a multiplexing part(460). The synchronizing data selecting/managing part receives additional data-related information synchronized with MPEG-2 video/audio transmission stream from the outside via an interface, and carries out searching and selecting the same from the additional data storing part. If the data is not in the additional storing part, the data is inputted and stored from the outside. The additional data storing part stores and manages all additional data used in the digital broadcasting in the file format. The additional data storing part outputs synchronizing data according to a control signal output from the synchronizing data inserting/managing part. The synchronizing data inserting/managing part calculates a time for inserting the synchronizing data into MPEG-2 video/audio transmission stream, considering the packet number of the MPEG-2 transmission stream, the reproducing time of the MPEG-2 transmission stream, and the null packet number of the MPEG-2 video/audio transmission stream.

Abstract: PURPOSE: A system and method for encoding data for digital ground-wave data broadcasting are provided to encode additional data according to ATSC data broadcasting standard so as to synchronize the additional data with a broadcasting program and transmit the data. CONSTITUTION: A data encoding system includes a controller(21), a protocol capsulation unit(22), an object divider(23), a table generator(24), a multiplexer(25), and an output unit(26). The controller generates a control signal according to encoding information inputted from the outside. The protocol capsulation unit capsulates additional data with a protocol defined by data broadcasting standard according to the control signal. The object divider divides an MPEG-4 file into an initial object descriptor, a binary format for scene, an object descriptor and a stream according to the control signal. The table generator generates a program specific information/service description framework table required for demultiplexing of data broadcasting transport streams. The multiplexer multiplexes transport stream packets inputted from the protocol capsulation unit and the table generator. The output unit outputs the transport streams received from the multiplexer.
