GENERAL DESCRIPTION
The SAA7134HL is a single chip solution to digitize and
decode video and sound, and to capture both data
streams through the PCI-bus.
Special means are incorporated to maintain the
synchronization of audio to video. The device offers
versatile peripheral interfaces (GPIO), that support various
extended applications, e.g. analog audio pass-through for
loop back cable to the sound card, or capture of DTV and
DVB transport streams, such as Vestigial Side Band
(VSB), Orthogonal Frequency Division Multiplexing
(OFDM) and Quadrature Amplitude Modulation (QAM)
decoded digital television standards (see Fig.1).

Introduction
The PCI audio and video broadcast decoder SAA7134HL
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 SAA7134HL 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.
Analog TV sound is digitized and stereo decoded (NICAM
and dual FM standards). Audio is streamed digitally via the
PCI-bus or routed as an analog signal via the loop back
cable to the sound card.
The SAA7134HL 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.

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.
