6.2 Application examples
The SAA7133HL enables PC TV capture applications both on the PC mother board and
on PCI add-on TV capture cards.

proposed tuner types incorporate the RF tuning function and the IF downconversion.
Usually the IF downconversion stage also includes a single channel and analog sound
FM demodulator. The NXP tuners FI1286 (Japan) and FI1236MK2 (USA and other NTSC
countries) are suitable for M standard. The FM12x6 are special versions for additional
FM radio reception. All types are suited for terrestrial broadcast and for cable reception.
The tuners provide composite video CVBS and audio as second SIF. These analog video
and sound signals are fed to the appropriate input pins of the SAA7133HL.
Further analog video input signals, CVBS and/or Y-C, can be connected via the board
back-panel, or the separate front connectors, e.g. from a camcorder. Accompanying
stereo audio signals can also be fed to the SAA7133HL.
Video is digitized and decoded to YUV. TV sound is digitized and decoded. The
SAA7133HL is able to decode stereo audio according to BTSC [also including the
Secondary Audio Program (SAP)] and stereo/dual audio according to EIAJ. In addition
mono decoding of FM and AM sound is possible. The digital streams are pumped via
DMA into the PCI memory space.
The SAA7133HL incorporates means for legacy analog audio signal routing. The on-chip
audio DACs convert the digital decoded stereo signal into analog audio. This analog audio
input signal is fed via an analog audio loop back cable into the line-in of a legacy sound
card. An external audio signal, that would have otherwise connected directly to the sound
card, is now routed through the SAA7133HL. This analog pass-through is enabled as
default by a system reset, i.e. without any driver involvement and before system set-up.
During the power-up procedure, the SAA7133HL will investigate the on-board EEPROM
to load the board specific system vendor ID and board version ID into the related places of
the PCI configuration space. The board vendor can store other board specific data in the
EEPROM that is accessible via the I
