Title:
COMPRESSION CODE DECODING DEVICE
Document Type and Number:
Japanese Patent JPS6384269
Kind Code:
A
Abstract:
PURPOSE:To attain the write by using a direct memory access control by outputting a decoded data as a parallel data so as to connect the titled device directly to an image memory or the like. CONSTITUTION:A synchronizing clock signal ACLK 9 is outputted synchronously with a CLK 13 from a control circuit 4. Since one page video signal 8 is sent by the output of a page synchronizing signal VSYNC 6, a line synchronizing signal BD-DR10 is outputted to command the transmission of the VIDEO signal 8. A decoder 2 receiving it outputs picture synchronizing signals VEN 7 and VIDEO 8. The output is sent synchronously with the ACLK 9, the parallel video interface 3 outputs a parallel picture data 11 in the stage of the arranged VIDEO 8 at the S/P conversion. In this case, the transmission of the signal 9 is stopped so that the next signal 8 is not sent and after the output of the picture data 11 is finished, the signal 9 is outputted to fetch the next signal 8 succeedingly to apply parallel conversion.
