SAA7134HL

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.

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.

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.
