Product data sheet
1. 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

1.1 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 optimally exploit the streaming capabilities of a modern host based system. Legacy
requirements are also taken care of.

SAA7134HL
PCI audio and video broadcast decoder
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.
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.
