The 3.58 MHz subcarrier signal with its modulated 'I' and 'Q' signals is added to the Y signal and composite NTSC is the result. During all this processing, which takes time, the Y channel must be delayed to account for the time difference.

The FM system uses a 19 kHz pilot (in order to keep the pilot as far away as possible from the high-frequency content of the main channel), and a 38 kHz stereo subchannel. The BTSC system uses a pilot at the NTSC horizontal scan frequency of 15,734 Hz, and a subchannel operating at twice that frequency or 31,468 kHz.

Actually, if we wanted to define the rates to the Nth degree, the importantstarting point is the field rate. The NTSC color frame rate was defined as(60 * 1000/1001) Hz, which is a bit more than 59.94 Hz. From this rate, allthe others in the system are defined. The line rate is 262.5 times this, andthe color subcarrier is defined as 455/2 times the line rate.

It should not significantly affect the quality of either video (as the audio subcarrier is outside the video bandwidth) or audio (as the audio carrier frequency of, depending on region, 4.5-6.5 MHz - and its bandwidth - are high enough to encode all audible frequencies). Stereo could also be carried the usual broadcast way (MTS, A2 or NICAM).

Converting (transcoding) NTSC 3.58 MHz subcarrier to PAL 4.43 MHz subcarrier is the easy bit. Many standard PAL VCRS can transcode an NTSC tape to PAL. They do this without converting the 525 line/sec and 60 field/sec scan rates. The result is PAL 60.

Reception quality on transponder 17, 4.085 GHz, Rc, was excellent with an audio subcarrier on 6.60 MHz. Some heavy noise in the sound could be observed during high saturated colors (of course the reds especially), but this could be blamed on the NTSC-PAL conversion, somewhere on it's way via Orion 1, from California, USA.
