Title: Reproducing circuit of chrominance signal
Inventor: KOJIMA NOBORU
IPC: H04N9/87
Filed: 1982-07-26
Abstract: PURPOSE:To simplify the circuit constitution and to prevent the change in hue from being produced on a reproduced screen, by determining suitably an oscillating frequency of a voltage controlled oscillator and using the frequency in common use for both the NTSC and the PAL systems. CONSTITUTION:A signal reproduced from a video tape is led to an output terminal 3 via an LPF4, a frequency converter 5, a BPF6 and a comb line filter 7. This output and an output of an oscillator 8 for APC are inputted to a phase detector 9 and its output is given to a VCO28. This VCO28 is controlled with an output of a frequency discriminator 30 and its oscillating frequency is selected to almost eight times the low frequency conversion chrominance subcarrier frequency. The output of the VCO 38 is frequency-divided by 1/8 at a frequency dividing circuit 29 and given to a frequency converter 13 via a phase shift circuit 12. The output of the frequency converter 13 is given to a frequency converter 5 via a BPF14.

Filed: 1989-05-22
Abstract: PURPOSE:To realize track division having length to validate all sectors by comprising a sector pulse sending circuit of a microprocessor, a ROM, a composite switch, two counters, and an AND gate. CONSTITUTION:The microprocessor 1 reads out the binary data of plural paral lel bits from the composite switch 6. After that, the processor 1 performs the calculation of C/n (C: the number of bytes per track, (n): the number of bytes to be divided), and finds the number (x) of bytes per sector, and sends it to the counter 3, and also, finds x(n-1)alpha, and sends it to the counter 4. When the speed of a spindle motor reaches constant rotating speed, a servo analog circuit 7 sends out an index pulse signal 15 at every c-byte interval, and also, sends out a byte clock signal 14. The counter 3 outputs a pulse signal 16 with x-byte interval, and the counter 4 outputs a signal 17 of logic 1 during a period of {x(n-1)+alpha} bytes. And the output signal 18 of a gate circuit 5 is used as a sector division signal.
