In the center between "Blank" 0 IRE and 100 IRE you will see the video signal (color-coded as to the actual color which produced it). The top and bottom red lines determine the 20% maximum and minimum limit under 0 IRE and over 100 IRE as defined by NTSC specifications.

The general test procedure is to apply a standard NTSC 1 volt (140 IRE) signal to the video path or equipment input. The test signal is then measured at various points along the signal path to verify its correct amplitude.

When converting between digital and analog, a digital value of 16 (Y') should correspond to 7.5 IRE for NTSC (except in Japan). The majority of DV devices however convert video levels incorrectly. On these devices, 16 (Y') will correspond to 0 IRE instead of 7.5 IRE.

When an NTSC DVD player plays the DVD, it is supposed to scale digital level 16 to analog level 7.5 IRE for correct NTSC black. If you play the tape from the camcorder to analog outputs, black will be incorrect at 0.0 IRE.

Television Engineers find it more convenient to specify signal levels in IRE rather than milivolts. Pure white is defined as 100 IRE and the blanking level is 0 IRE. NTSC video has 714 mV between blanking and peak white so 1 IRE is 7.14 mV.

The only software that I know of that uses the Dreamcast's midi cable, in fact the midi cable was probably made just for this software. ... As the title says, this is a music sequencer for Dreamcast that can be connected to There are numerous different pre programmed melodies with in the software as well as many wave samples.

The problem for DV users in North America is that DV 25 video equipment (named for the 25 megabit per second data rate of this popular video format), whether it is PAL or NTSC has an analog output of 0 IRE.
