Analog TV signals are described in three categories of
standards:
TV signals that are broadcasted usually conform fairly
accurately to the standards. Transmission over the air or
through a cable can distort the signal with noise, echoes,
crosstalk or other disturbances.

RF modulation scheme
Colour transmission: defining colour coding and
modulation method

Video signals from local consumer equipment, e.g. VCR,
camcorder, camera, game console, or even DVD player,
often do not follow the standard specification very
accurately.
Playback from video tape cannot be expected to maintain
correct timing, especially not during feature mode (fast
forward, etc.).
Tables 12 to 14 list some characteristics of the various
TV standards.
The SAA7130HL decodes all colour TV standards and
non-standard signals as generated by video tape
recorders e.g. automatic video standard detection can be
applied, with preference options for certain standards, or
the decoder can be forced to a dedicated standard.
