ABSTRACT:
A high definition television production system generates a high definition video signal that is easily convertible to signals formatted in accordance with other television and film standards of release media. Such other standards may include 525/60 and 625/50 formats and film formats having a frame rate of 24 film frames per second. The HDTV system employs vertical line scanning in the camera to generate the HDTV signal. The horizontal field scanning rate is chosen to be the lowest common integral multiple of the frame rates of the release standards of interest. The interlace factor is selected high enough to provide good temporal sampling and to result in a vertical line scanning frequency that yields an integral number of HDTV scan lines in the field or frame time of the release standards. The video sampling rate is selected to be compatible with the 13.5 megahertz digital world standard studio rate.
