Please excuse my ignorance but I'm not sure I understand you correctly, Isn't PAL_SECAM an analogue television colour encoding system used in broadcast television and has been superseded by digital TV?
AdobeRGB, sRGB and ProPhoto are colour space profiles, and should have no connection to PAL_SECAM or NTSC.
I expect I am wrong as I am a noob when it comes to videos (movies) but I think you are talking about a Photo presentation (a series of stills) and I fail to make a connection between Analogue TV and colour space profiles for stills.
