Why NTSC has a ~59.94 hz field rate
by Hijexx at 2:58 pm EST, Feb 9, 2007 |
Was doing research on de-interlacing NTSC, as well as reading up on HDTV broadcasting. Ran accross this excellent description of how the ~59.94 hz field rate came to be. It was an artifact of retaining backwards compatibility with black and white TV's. I didn't know that technically the field rate was dropped by a factor of 1000/1001. |

Fascinating! I never thought it was arbitrary, but i also never understand the importance of 59.94... thanks! |

Yeah, it always bugged me not understanding what it was for but I never researched it. Makes sense though. You might find 44100 Explained interesting as well. 44100 seemed arbitrary until I found out what the reasoning was. |

Also very interesting... it's remarkable to think about how many things we take for granted have such a long and complex history. Thanks for the insight! |
