2. Serial clock line and data line
This serial clock signal is a reference signal which is used to
control the timing of the data transmission among the
microprocessors.
The previous transmission has only 13 clocknumber, the
new serial data transmission has 20 clock number in it.
Blocks 1 to 10 of both formats will be the same.

system control microprocessor, timer microprocessor and
edit microprocessor.
And 5P Clock which is composed of the clock no. 1, 3, 4, 5,
7, 8, 9 works to transmit the data between the edit micro­
processor and the VTR or MOVIE CAMERA which has an
