Title: Flip-flop circuit with clock signal control function and clock control signal
Inventor: HAMADA MOTOTSUGU
IPC: H03K3/012
Filed: 1999-08-23
Granted: 2001-01-21
Abstract: This invention discloses flip-flop circuit with clock signal control function and clock control signal. The inconsistence detection circuit DDC and clock control circuit CCC are installed in the flip-flop circuit 10. The inconsistence detection circuit DDC is used to detect the inconsistence between the data input signal DIS and the data output signal DOS of the flip-flop circuit 10. When data input signal DIS is inconsistent with data output signal DOS, clock control circuit CCC is synchronized with the rise of external clock signal ECLK and the short pulse is used as the internal clock signal ICLK sent to the flip-flop circuit 10. On the other hand, when data input signal DIS is consistent with data output signal DOS, low voltage level signal is used as the internal clock signal ICLK sent to the flip-flop circuit 10. Therefore, the consumed electricity required for supplying the clock signal can be reduced and furthermore, the error occurred in the flip-flop action can be prevented.

The transmission device multiplexes the first and the second data streams and then transmits the multiplexed data stream. The transmission of the multiplexed data stream is controlled so that a transmission rate for the multiplexed data stream does not exceed the maximum transmission rate, and so that a transmission rate for the first data stream becomes lower than that for the second data stream. A receiving device records the first data stream on the recording medium, and permits the first data stream to be played back for use after the transmission completes.
