If not, the digital data is analyzed and decoded through an analytic platform and a decoder platform according to an identifying code of data flow and the first subtitle set image control signal. Then a mixed digital video signal and a digital audio signal are outputted by an image construct platform and an output platform. The interface management platform of receiving end continuingly transmitting a decoded message of a second subtitle set image to the comparison platform and the comparison platform reads control signal of the second subtitle set image and compares it with the first subtitle set image retained temporarily in the accumulator register for decoding the subtitle set image contol signal inexistent in the accumulator register.
