<p>PROBLEM TO BE SOLVED: To synthesize a data string having frame constitution by proper multiplexing. SOLUTION: Data memories 10 record data strings having frame constitution inputted from a data string generation source. In this case, when detecting the input start of the data strings, a control processing part 14 operates a frame counter 14a and before the lapse of a period for inputting data strings for one frame, the part 14 discriminates whether all of the data memories 10 have started writing of the data strings. In the case of judging that they have started then, the part 14 restarts the counter 14a, stands by until the period for inputting data strings for one frame elapses and then sends a synthesis control signal for instructing the start of processing for synthesizing the data strings to a TS synthesis processing part 11. In accordance with the synthesis control signal, the part 11 reads the data strings recorded in the memories 10 and multiplexes them for synthesis.</p> |
