Title:
RECORDING MEDIUM
Document Type and Number:
Japanese Patent JPS63146289
Kind Code:
A
Abstract:
PURPOSE:To display the reproduction progress positions for each program by recording the reproduction progress time information each program to a disk record which records the continuous main information on the video signals, etc. CONSTITUTION:A recording medium records with multiplexing the program reproduction progress time information set for each program in a prescribed cycle. The reproduction video signals demodulated by an FM demodulation circuit 1 are inputted to a decoding circuit 2 which decodes the biphase codes as well as to a sampling pulse generating circuit 3. Each decoded output is stored in a frame number circuit 4 consisting of a shift register, a frame number memory circuit 5 and a total frame number memory circuit 6 respectively in response to each sampling pulse. Each bit output is inputted to a subtraction circuit 7 for calculation of the number of remain frames. A multiplexer 8 which uses the subtraction output and the frame number as selective inputs selects the input signals by the control output CN. The selected output converts the frame display into the second display via a conversion circuit 9 of the next stage to supply it to a character generator 10.
