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.

FEATURES

PCI and DMA bus mastering

? PCI 2.2 compliant including full Advanced Configuration and Power Interface (ACPI)

? System vendor ID, etc. via EEPROM

? Hardware support for virtual addressing by MMU

? DMA bus master write for video, audio, VBI and TS

? Configurable PCI FIFOs, graceful overflow

? Packed and planar video formats, overlay clipping.

TV video decoder and video scaling

? All-standards TV decoder: NTSC, PAL and SECAM

? Five analog video inputs: CVBS and S-video

? Video digitizing by two 9-bit ADCs at 27 MHz

? Sampling according ITU-R BT.601 with 720 pixels/line

? Adaptive comb filter for NTSC and PAL, also operating for non-standard signals

? Automatic TV standard detection

? Three level Macrovision copy protection detection according to Macrovision Detect specification Revision 1

? Control of brightness, contrast, saturation and hue

? Versatile filter bandwidth selection

? Horizontal and vertical downscaling or zoom

? Adaptive anti-alias filtering

? Capture of raw VBI samples

? Two alternating settings for active video scaling

? Output in YUV and RGB

? Gamma compensation, black stretching.

TV sound decoder and audio I/O

? TV stereo decoding for NICAM and dual FM

? Audio sampling locked to video field rate, no drift of audio stream against video stream

? On-chip stereo audio ADCs and DACs (2 × 16-bit)

? Sampling rate, e.g. 32, 44.1 and 48 kHz

? Integrated analog audio pass-through for analog audio loop back cable to sound card.

Peripheral interface

? I2C-bus master interface: 3.3 and 5 V

? Digital video output: ITU and VIP formats

? TS input: serial or parallel

? General purpose I/O, e.g. for strapping and interrupt

? Propagate reset and ACPI state D3-hot.

General
