SAA7133HL

General description

The PCI audio and video broadcast decoder SAA7133HL is a highly integrated, low cost and solid foundation for TV capture in the PC, for analog TV and digital video broadcast (DTV and DVB). The various multimedia data types are transported over the PCI-bus by bus-master-write, to optimize the streaming capabilities of a modern host based system; see Figure 1. Legacy requirements are also taken care of.

The SAA7133HL meets the requirements of PC Design Guides 1998, 1999 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 (BTSC and EIAJ). Audio is streamed digitally via the PCI-bus or the I²S-bus or routed as an analog signal via the loop back cable to the sound card. The SAA7133HL provides a versatile peripheral interface to support system extensions, e.g. MPEG encoding for time shift viewing.

The channel decoder for digital video broadcast reception (ATSC or DVB) can re-use the integrated video ADCs.

The Transport Stream (TS) or Program Stream (PS) 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.
