NTSC AES

  1. 24.167829MHz main clock / 4 = 6.041957MHz pixel clock
  2. 6.041957MHz / 384 pixels per line = 15.734kHz horizontal rate
  3. 15.734kHz / 264 lines = 59.599 frames/second

PAL AES

  1. 24.167829MHz main clock / 4 = 6.041957MHz pixel clock
  2. 6.041957MHz / 384 pixels per line = 15.734kHz horizontal rate
  3. 15.734kHz / 312 lines = 50.429 frames/second

MVS

  1. 24.000000MHz main clock / 4 = 6.000000MHz pixel clock
  2. 6MHz / 384 pixels per line = 15.625kHz horizontal rate
  3. 15.625kHz / 264 lines = 59.1856 frames/second
