SAA7130HL
PCI video broadcast decoder
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.
Audio is routed as an analog signal via the loopback 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.
1.2 Overview of TV decoders with PCI bridge
A TV decoder family with PCI interfacing has been created to support worldwide
TV broadcasting. The pin compatibility of these TV decoders offers the opportunity to
support different TV broadcast standards with one PCB layout.
