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.
