<P>PROBLEM TO BE SOLVED: To generate a stream, through which data to be used in common and data to be used only by a present station flow in an order, by merely selecting the stream to be used in each station. <P>SOLUTION: A content stream transmitter 1 and a meta data stream transmitter 2 output the stream of the data to be utilized, in common as a whole and the stream of the data to be utilized by being selected by individual broadcasting stations, by different PIDs exclusively in terms of time. A multiplxer 3 multiplexes the output streams of the content stream transmitter 1 and the meta data stream transmitter 2. A PID for selecting and replacing a device 4 selects a single PID of the stream of the data to be utilized in common and one PID of the stream of the data to be utilized, by being selected by the individual broadcasting stations from multiplexed data streams, replaces the selected PID with one PID and deletes the stream of the unselected PID. <P>COPYRIGHT: (C)2007,JPO&INPIT |
