8.10.10 Data Clock Generating Circuit
This circuit generates a data clock synchronized with the start bit
detected in the start bit detecting circuit. The data clock stores cap-
tion data to the 16-bit shift register. When the 16-bit data has been
stored and the clock run-in determination circuit determines clock
run-in, the caption data latch completion flag is set. This flag is reset
at a falling of the vertical synchronous signal (V
sep
).
