SAA7134HL
PCI audio and video broadcast decoder
6.5 Analog TV standards
Analog TV signals are described in three categories of standards:
Basic TV systems: defining frame rate, number of lines per field, levels of
synchronization signals, blanking, black and white, signal bandwidth and the
RF modulation scheme
Color transmission: defining color coding and modulation method
Sound and stereo: defining coding for transmission
TV signals that are broadcast 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.
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.).
Table 14
to
Table 16
list some characteristics of the various TV standards.
The SAA7134HL decodes all color 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.
The SAA7134HL incorporates TV stereo decoding for NICAM and dual FM sound
systems. BTSC and EIAJ are demodulated to monaural sound, but stereo decoding can
be added externally. Baseband stereo audio can be fed into the device as analog signal,
or in digital form in I
2
S-bus format.
