2.1 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.
