    My major is computer science. Iam working on a project that deals with
    analog and digital video signals. I understood that NTSC, PAL and SECAM
    are analog broadcast standards. Does it necessarily mean that the above
    mentioned three are three types of analog signals. If that is true
    ATSC, DVB-T, ISDB-T should be the digital broadcast standards or the
    types of digital video signals.
    My concern is regarding TTL, CMOS, Firewire, DV. What are
    these? Are they different types of digital video signals? If not what
    relation does each of those hold with a digital video signal? these
    questions have been bugging me. Please do help.
    Thanks in advance.
