Abstract:
A multiplex and demultiplex controlling apparatus comprising:multiplex and demultiplex means for demultiplexing multiplexed image data and control data from each other, adding time information to said demultiplexed image data and control data, respectively, and outputting them; storage means for temporarily storing an output from said multiplex and demultiplex means; timing controlling means for generating read-out indication of corresponding 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 read-out indication of said timing controlling means, and conducting a feedback output of time information to be 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 read-out indication of said timing controlling means, and conducting a feedback output of time information to be 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 control processing means, respectively.
