Remarks

This enumeration defines various analog television broadcast standards used worldwide. The standards are grouped into three main families: NTSC (National Television System Committee), PAL (Phase Alternating Line), and SECAM (Séquentiel couleur à mémoire). Each standard has regional variations denoted by letters or numbers. The enumeration also includes bit masks for filtering standards by family.
