Product data sheet

1. General description

The SAA7130HL is a single chip solution to digitize and decode video, and capture it

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 loopback 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 Figure 1.

1.1 Introduction

The PCI video broadcast decoder SAA7130HL 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.
