Abstract: When a recording start executed in a variable-speed recording mode, at ST44 a signal having a variable frame rate is selected on the basis of a validity signal from among image signals having a predetermined output frame rate in which the images having the variable frame rate are contained and stored in a memory. If it is decided at ST46 that a phase difference between a write position and a read position in the memory has reached a recording start level, the stored signal is recorded in a recording medium at ST47. If it is decided at ST48 that the phase difference has decreased to a recording stop level, recording to the recording medium is stopped at ST49. When an end operation is executed at ST51, the signal in the memory is recorded in the recording medium to then end actions. The signals are selected and recorded, thus resulting in a smaller signal quantity. Further, if the variable frame rate is varied, video effects can be confirmed only by reproducing the recorded signals.

Abstract: The present invention provides an apparatus for generating a time code compatible with 50P, 60P or 59.94P and having interchangeability with existing time codes. The apparatus includes: a microcomputer for dividing a frame number indicated by time address data in supplied code word data to obtain a quotient and a remainder; and the microcomputer and a time code reader for replacing the frame number indicated by the time address data in the code word data with the quotient and for generating a time code based on the code word data in which a value of a color frame flag is set to 0 if the remainder is 0 and for replacing the frame number with the quotient and for generating the time code based on the code word data in which the value of the color frame flag is set to 1 if the remainder is 1.

Abstract: A method for processing a time code including the steps of generating information, indicating whether or not a location is proper for editing when converting picture information of a predetermined system into picture information of another system, and writing the information to the time code data accompanied with the picture information of the second system.

Abstract: In a method for processing a time code such that time code data composed of a hour minute second frame accompanying picture information of a predetermined system is mapped onto picture information of another system, when converting the picture information of the predetermined system into that of another system, mapping the time code when converting the system of the picture information including the steps of converting time code data accompanying picture information of said predetermined system into a total frame number x, calculating a total frame number y of the converted time code data for said time code data from said total frame number x and generating the converted time code from the total frame number y.
