Motherboard Description The motherboard provides two inputs for video on the video riser card I/O panel: an RCA input connector for composite video signals, and a 7-pin mini-DIN connector for S-Video signals and Inter-Integrated Circuit (I2C) signals. The Bt829A's registers are accessed using the I2C interface. The Bt829A operates as an I2C slave device. To reprogram the default settings, you must connect an I2C master to the 7-pin mini-DIN I2C/S-Video connector. The I2C serial clock and data lines transfer data from the master device at a rate of 100 Kbits/sec. 1.9.3.1 Video Capture Input Connector A 1x4 pin connector is available on the motherboard for applying a composite video signal (from a TV Tuner add-in card, for example) to the input of the Brooktree Bt829A Video Capture device. Two pins are dedicated to external control capability via the I2C protocol using serial clock (SCL) and serial data (SDA) pins. 1.9.3.2 Video Capture Drivers and Utilities Video capture software and utilities are available from Intel's World Wide Web site (see Section 5.2). 1.9.4 ImpacTV NTSC/PAL Encoder The optional ATI-ImpacTV NTSC/PAL Encoder is an ASIC that provides a TV-out interface for the ATI-264GTB 3D Rage II+ multimedia graphics accelerators. Quality issues such as image flicker, illegible text and low-definition graphics are controlled through on-chip circuitry for scaling, flicker removal, and artifact suppression. Features include: • Circuitry for producing interlaced images with flicker removed • Circuitry for eliminating dot crawl • Filters for bringing out detail in fine text while suppressing color artifacts • Support for both NTSC and PAL formats • Filters that ensure signal bandwidth does not exceed TV standards • Fully programmable timing that enables NTSC or PAL signals to be generated from monitor resolutions that include 320x200, 320x240, 320x350, 320x400, 360x200, 360x240, 360x400, 360x440, 512x384, 640x350, 640x400, 640x480, 720x350, 720x400, 720x480, and 800x600 • Simultaneous display of images on both a TV and a PC monitor • Independent horizontal positioning of the TV image and the PC monitor image • Independent vertical positioning of the TV image and the PC monitor image • Independent horizontal scaling of the TV image and the PC monitor image • Power management for full VESA DPMS and EPA Energy Star compliance • Automatic power down of the ASIC at initialization if a TV is not detected • Support for both composite and S-Video connectors The motherboard provides two outputs for video on the video riser card I/O panel: an RCA connector for composite video-out signals and a 4-pin mini-DIN connector for S-Video output signals. 21

Motherboard Description
21
The motherboard provides two inputs for video on the video riser card I/O panel:
an RCA input
connector for composite video signals, and a 7-pin mini-DIN connector for S-Video signals and
Inter-Integrated Circuit (I
2
C) signals.
The Bt829A’s registers are accessed using the I
2
C interface.
The Bt829A operates as an I
2
C slave
device.
To reprogram the default settings, you must connect an I
2
C master to the 7-pin mini-DIN
I
2
C/S-Video connector.
The I
2
C serial clock and data lines transfer data from the master device at
a rate of 100 Kbits/sec.
1.9.3.1
Video Capture Input Connector
A 1x4 pin connector is available on the motherboard for applying a composite video signal (from a
TV Tuner add-in card, for example) to the input of the Brooktree Bt829A Video Capture device.
Two pins are dedicated to external control capability via the I
2
C protocol using serial clock (SCL)
and serial data (SDA) pins.
1.9.3.2
Video Capture Drivers and Utilities
Video capture software and utilities are available from Intel’s World Wide Web site (see
Section 5.2).
1.9.4

The optional ATI-ImpacTV NTSC/PAL Encoder is an ASIC that provides a TV-out interface for
the ATI-264GTB 3D Rage II+ multimedia graphics accelerators.
Quality issues such as image
flicker, illegible text and low-definition graphics are controlled through on-chip circuitry for
scaling, flicker removal, and artifact suppression.
Features include:
•
Circuitry for producing interlaced images with flicker removed
•
Circuitry for eliminating dot crawl
•
Filters for bringing out detail in fine text while suppressing color artifacts
•
Support for both NTSC and PAL formats
