Signal recording system of rotary recording medium
专利汇可以提供Signal recording system of rotary recording medium专利检索，专利查询，专利分析的服务。并且PURPOSE: To reproduce data on the basis of an interactive system between a reproducing device and an external control apparatus, based on only a control program signal of a specified field discriminated by a block discriminating signal, by recording the block discriminating signal in the control program signal by applying time division multiplexing.
CONSTITUTION: A decoder 7 discriminates the number of horizontal synchronizing signals which follow a vertical synchronizing signal, and in an output terminal 10, the first period extending from the 22H-th of a scanning line number to the 261H-th line, and the second period extending from the 285H-th line to the 524H-th line make a selector 4 output selectively a modulated wave signal of a control program signal from a control program signal generating circuit 1. Also, in other period than the first and the second periods, a control signal for outputting selectively the signal from a signal generating circuit 2, from the selector 4 is generated and supplied to the selector 4. The signal outputted selectively from the selector 4 is supplied to a latching circuit 8, and latched by a signal of a frequency of two times of the horizontal synchronizing signal. A digital signal from the latching circuit 8 is outputted to the output terminal 10 whose band has been limited to a sound signal band through a low-pass filter 9, and recorded together with a video signal.
