Title:
DATA REPRODUCTION DEVICE
Document Type and Number:
Japanese Patent JPH05217340
Kind Code:
A
Abstract:
PURPOSE:To display lap time from the leading position of music by conforming a timing to a signal being reproduced at present. CONSTITUTION:Main data is sent to a D/A converter 7 at a constant rate and is outputted via an LPF 8 by taking out the main data by decoding data separated at every music read from a disk 1 by a signal processing part 4, and performing read/write control on a RAM 6 for buffer by a RAM controller 5. A system controller 10 finds delay quantity between read and write based on the amount of data accumulated in the RAM 6 for buffer, and finds in-music lapse time(lap time) by subtracting the absolute time of the leading position of the music and the delay quantity from the absolute time obtained by subcode data from the signal processing part 4, then, it is displayed on a display part 11.
