Product specification
PCI audio and video broadcast decoder
SAA7134HL

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
Colour transmission: defining colour coding and
modulation method
Sound and stereo: defining coding for transmission.
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.
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 SAA7134HL 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.
The SAA7134HL incorporates TV stereo decoding for
NICAM and dual FM sound systems. BTSC and EIAJ are
demodulated to mono-aural 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.
