Multiplex and demultiplex controlling apparatus, multiplex and demultiplex controlling system, and method thereof

A multiplex and demultiplex controlling apparatus comprising:

• multiplex and demultiplex means for discriminating between an image data and a control data from a packet which has been transmitted, based on a head of said packet, and demultiplexing an image data stream and a control data stream from each other, and for adding time information to said demultiplexed image data stream and control data stream, respectively;
• storage means for temporarily storing an output from said multiplex and demultiplex means;
• timing controlling means for generating a timing signal for indicating read-out of said stored image data and control data in accordance with synchronous timing corresponding to said time information which is added to said image data and control data stored in said storage means;
• image reproducing means for reproducing an image data read out from said storage means in response to said timing signal, and conducting a feedback output of time information which is added to said reproduced image data;
• control processing means for conducting a control processing in accordance with a control data which is read out from said storage means in response to said timing signal, and conducting a feedback output of time information which is added to said control data;
• and
• timing correcting means for correcting said synchronous timing of said timing controlling means in response to a difference between time information fed back from said image reproducing means and said control processing means, respectively.
