Title:
MULTIPLEXING METHOD FOR TRANSFER OF DATA
Document Type and Number:
Japanese Patent JP3300520
Kind Code:
B2
Abstract:
PURPOSE: To transfer the reel-time information with no delay of time by reading first the normal information excluding several head packets to be sent earlier and then multiplexing several head packets of real-time information to immediately send them.
CONSTITUTION: The normal information D14-D190 are previously inputted among those information to be transferred in a frame memory (1) 109. Then the information D1 and then D2 are inputted and also the information D1 is outputted in a frame cycle. The information D2 is outputted when the information D3 is inputted. Thus the information are continuously inputted up to the D13, and the vertical parity calculation is carried out to prepare for output of P1. Meanwhile the information D1-D15 which are precedently inputted are outputted in reference to the output data. Since all of the parity calculations are completed in this step, other information P1, D16,..., D190 and P82 are stored in a memory 1 and may be outputted in sequence. An output switch 112 is changed over toward a memory 2 when the information P82 is sent. Then the memory 1 starts to input the data D1-D190 and carries out again the preceding operations.
