Time information method of presentation null of rotary hetsudo type

摘要

PURPOSE:To exactly display the real passage of time from the starting edge of a tape by displaying absolute time information when discriminated tape velocity is the first velocity, and displaying time information corresponding to the second velocity based on the absolute time information in the case of the second velocity. CONSTITUTION:A sound signal inputted to an input terminal 1 is converted to a digital signal by a signal processing circuit 2 and afterwards recorded through a recording amplifier 6 and a rotary transformer 7 to the tape together with a servo signal from a servo signal generating circuit 3 and a sub code signal (start ID, music number and absolute time information) from a sub code signal generating circuit 4. At the time of reproducing, when a long time mode is set, the output of a reproducing amplifier 9 reproduced from the tape is sent to a sub code processing circuit 13 and the reproduced absolute time is made double. Then, when a frame number is more than 17, 1 is added to a duplexed value and displayed through a control circuit 21. When the number is 17, the value is displayed as it is. On the other hand, in a standard mode, the reproduced absolute time is displayed as it is.
