Abstract
A video signal recording method and apparatus in which a video signal for a high definition television system is converted into a video signal for a current television system and recorded on record media. These video signals are recorded so as not to cause a deterioration in picture image quality such as color phase irregularity. According to the present video signal recording method, a screen to be displayed in a high definition television system is divided into a plurality of screens, video signals of each of which are then converted into signals of a current television system. A luminance signal and a chrominance signal of each of the signals of the current television system are time division multiplexed. Signals obtained from the time division multiplexing are recorded onto a plurality of record media with or without a color burst signal added thereto for each line.
