Mario Pavićević kaže: Pregled poruke
PAL kao druga evropska alternativa NTSC-u(francuski SECAM je bio prvi) nije izmisljen zato sto se nekom tako cefnulo, vec zbog problema koje NTSC ima(otud i cuveno tumacenje NTSC-Never twice same color), SECAM-ovih problema sa preklapanjima boja, kao i zbog razlike u strujnoj mrezi koja se koristi na americkom i evropskom kontinentu(60Hz amerika 50Hz Evropa). Mislim da bi smo ipak trebali da zadrzimo raspravu na objektivnom nivou a ne da ulazimo u domen teorija zavere.
Da ljudi ne pomisle da ja lupetam evo citata da nisu samo tehnicke prednosti uticale na izbor vec i namerna nekompatibilnost:

Citat:
Political factors from the Cold War have also been attributed to the adoption of SECAM in Eastern Europe, as its use made it impossible for most Eastern Europeans to view television which was broadcast from outside the Iron Curtain which were mostly using PAL.

Citat:
French designed a system of their own - primarily for political reasons to protect their domestic manufacturing companies - which is known as SECAM, standing for SEquential Couleur Avec Memoire.
Citat:
SECAM was widely adopted in the former Eastern Block countries to encourage incompatibility with Western transmissions - again a political motive. SECAM is further split between several variants.

Citat:
SECAM was not developed for any technical reason of merit (as was PAL) but was mainly invoked as a political statement, as well as to protect the French manufacturers from stiff foreign competition. In that regard, they were highly successful !.....

Citat:
PAL was developed by Telefunken, a German company, and in the post-war De Gaulle era there would have been much political resistance to dropping a French-developed system and adopting a German-developed one instead

Citat:
Contrary to American Method. Eastern Block countries adopted this format for purposeful incompatibility with western transmissions, possibly also political reasons.
