Abstract:
A video signal recorder comprising:(a) inter-frame encoding means for coding a video signal of a moving image the encoding means employing a variable bit rate code to vary data quantity in response to video signal complexity;(b) memory means for storing coded data corresponding to the video signal;(c) recording means for converting the stored coded data into a record signal;(d) drive means for selectively driving a recording medium,(e) control means for controlling an intermittent recording in which the recording means records data to the recording medium when the data quantity stored in the memory means is greater than a predetermined amount A1, and recording being halted when the data quantity stored in the memory means is less than a predetermined amount A2, the control means selectively driving the drive means, refraining from driving the drive means when a record instruction is absent, when a record instruction is given, substantially at the same time, enables coding with the encoding means, actuates the drive means, and sequentially store data coded with the encoding means into the memory means, after a delay, a record operation is performed to read out the data stored in the memory means, then convert the data into record signals with the recording means when the drive means reaches a predetermined rotational speed, and finally recording the signals to the record medium,wherein the maximum rate of the variable bit rate code is less than a recording rate of a recording medium so that no information is lost during the delay between the time of the record instruction and the performance of a record operation.
