2.1
The PCI video broadcast decoder SAA7130HL is a highly
integrated, low cost and solid foundation for TV capture in
the PC, for analog TV and digital video broadcast. The
various multimedia data types are transported over the
PCI-bus by bus-master-write, to optimum exploit the
streaming capabilities of a modern host based system.
Legacy requirements are also taken care of.
The SAA7130HL meets the requirements of PC Design
Guides 98/99 and 2001 and is PCI 2.2 and Advanced
Configuration and Power Interface (ACPI) compliant.
The analog video is sampled by 9-bit ADCs, decoded by a
multi-line adaptive comb filter and scaled horizontally,
vertically and by field rate. Multiple video output formats
(YUV and RGB) are available, including packed and
planar, gamma-compensated or black-stretched.

PCI-bus
Audio is routed as an analog signal via the loop back cable
to the sound card.
The SAA7130HL provides a versatile peripheral interface
to support system extensions, e.g. MPEG encoding for
time shift viewing, or DSP applications for audio
enhancements.
The channel decoder for digital video broadcast reception
(ATSC or DVB) can re-use the integrated video ADCs.
The Transport Stream (TS) is collected by a tailored
interface and pumped through the PCI-bus to the system
memory in well-defined buffer structures. Various internal
events, or peripheral status information, can be enabled as
an interrupt on the PCI-bus.
