Introduction / Overview
1-3
The television output circuitry supports both NTSC and PAL standard formats, and scales images
appropriately for both television formats and panels.
HiQVideo Multimedia Support
The 69000 uses independent multimedia capture and display systems on-chip. The capture system places
data in display memory (usually off screen) and the display system places the data in a window on the
screen.
The capture system can receive data from either the system bus or from the ZV enabled video port in either
RGB or YUV format. The input data can also be scaled down before storage in display memory. Capture
of input data may also be double buffered for smoothing and to prevent image tearing. To better support
MPEG2 (DVD) video decompression, the 69000 includes a line buffer to directly support the native format
of MPEG2 data of 720 pixels wide.
The capture engine also supports image mirroring and rotation for camera support. This feature is important
for applications such as video teleconferencing because it allows the image movements to appear on the
display as it actually occurs. The image and movement is not a mirror image of what is actually taking place.
The display system can independently place either RGB or YUV data from anywhere in display memory into
an on-screen window which can be any size and located at any pixel boundary (YUV data is converted to
RGB "on-the-fly" on output). This is important for the 69000 since the video must be stored in the integrated
2MB frame buffer and thus optimized to require very little space. Storing data in the native YUV format uses
less memory for video while providing excellent playback display quality.
Non-rectangular windows are supported via color keying. The data can be fractionally zoomed on output
up to 8x to fit the on-screen window and can be horizontally and vertically interpolated. Interlaced and non-
interlaced data are both supported in the capture and display systems.
Low Power Consumption
The 69000 uses a variety of advanced power management features to reduce power consumption of the
display sub-system and to extend battery life. Optimized for 3.3V operation, the 69000 internal logic, bus
and panel interfaces operate at 3.3V but can tolerate 5V operation.
Software Compatibility / Flexibility
The HiQVideo controllers are fully compatible with the VGA standard at both the register and BIOS levels.
CHIPS and third-party vendors supply a fully VGA compatible BIOS, end-user utilities and drivers for
common application programs.
Acceleration for All Panels and All Modes
The 69000 graphics engine is designed to support high performance graphics and video acceleration for all
supported display resolutions, display types, and color modes. There is no compromise in performance
operating in 8, 16, or 24 bpp color modes allowing true acceleration while displaying up to 16.7M colors.
