Video

Video-88AGP-3D (NVIDIA Vanta) accelerates full motion video playback under DirectDraw using hardware overlay scaling and color space conversion integrated into the Palette-DAC pipeline. This overlay pipeline features smooth up and down scaling with multitap X and Y sub-pixel interpolation, optional edged enhancement and per-pixel color keying. Interlaced video is double buffered at 60Hz with both odd and even fields displayed.

VIDEO SCALER PIPELINE

Video-88AGP-3D (NVIDIA Vanta) video scaler pipeline performs stretching of video images in any arbitrary factor in both horizontal and vertical directions. The video scaler pipeline consists of the following stages:

Vertical stretching

Filtering

Color space conversion

Horizontal stretching

Vertical stretching

Vertical stretching is performed on pixels prior to color conversion. The video scaler linearly interpolates the pixels in the vertical direction using an internal buffer which stores the previous line of pixel information.

Filtering

After vertical interpolation, the pixels are horizon-tally filtered using an edge-enhancement or a smoothing filter. The edge-enhancement filter enhances picture transition information to prevent loss of image clarity following the smoothing filtering stage. The smoothing filter is a low-pass filter that reduces the noise in the source image.

Color space conversion

The video overlay pipeline logic converts images from YUV 4:2:2 format to 24-bit RGB true-color. The default color conversion coefficients convert from YCrCb to gamma corrected RGB. Saturation controls make sure that the conversion does not exceed the output range. Four control flags in the color converter provides 16 sets of color conversion coefficients to allow adjustment of the hue and saturation. The brightness of each R G B component can also be individually adjusted, similar to the brightness controls of the monitor.

Horizontal stretching

Horizontal stretching is done in 24-bit RGB space after color conversion. Each component is linearly interpolated using a triangle 2-tap filter.

Windowing and panning

Video images are clipped to a rectangular window by a pair of registers specifying the position and width. By programming the video start address and the video pitch, the video overlay logic also supports a panning window that can zoom into a portion of the source image.

Video composition

With the color keying feature enabled, a programmable key in the graphics pixel stream allows selection of either the video or the graphics output on a pixel by pixel basis. Color keying allows any arbitrary portions of the video to overlay the graphics. With color keying disabled and video overlay turned on, the video output overlays the graphics in the video window.

Interlaced video

The video overlay can display both non-interlaced and interlaced video. Traditional video overlay hardware typically drops every other field of an interlaced video stream, resulting in a low frame rate. Some solutions have attempted to overcome the this problem by de-interlacing the fields into a single frame. This however introduces motion artifacts. Fast moving objects appearing in different positions in different fields, when de-interlaced, introduces visible artifacts which look like hair-like lines projecting out of the object.

Technical Assistance

Q: Why is the display shifted or changed sizes when I switch display modes?

Explain and Suggestion:

Some monitors lack auto-sizing features or just do not synchronize properly to the video board output. In some cases, horizontal and vertical display adjustments may be necessary. Use the monitor control panel functions to adjust screen.

In other cases, mode type and refresh rate adjustments may be necessary. Use the utility program, which provided by video card manufacturer or production developer. To centering the display with normal type (mode 3), and to reduce (decrease) the refresh rate with the monitor's specification.

Q: What kind monitors can display 800x600 mode or higher resolution mode?

Explain and Suggestion:

To display 800x600 resolution at 60Hz refresh rate, the monitor must be capable of synchronizing a 31.5KHz horizontal scan rate (e.g., NEC 2A, 3D). At 72Hz refresh rate, the monitor must be capable of synchronizing a 48.0KHz scan rate (e.g., Sony HG 1304, NEC 4D, 5D, Seiko 1450).

To display 1024x768 interlaced mode; the monitor must be capable of synchronizing a 35.5KHz horizontal scan rate (e.g., NEC 3D, Seiko 1430 or 1440). To display 1024x768 non-interlaced mode at 60Hz, the monitor must be capable of synchronizing a 48.7KHz scan rate (e.g., Sony HG 1304, NEC 4D, 5D, Seiko 1450).

To display 1024x768 non-interlaced mode at 70Hz, the monitor must be capable of synchronizing a 56.4KHz scan rate (e.g., NEC 4D).

Q: Windows screen won't come up, it kicks back to

DOS prompt. Why?

Explain and Suggestion:

Windows 95

Inadvertently, certain configuration files (e.g., msdos.sys, and command.com) have been changed in the system. Proceed to correct that, is re-boot the system with a system (Windows 95) formatted floppy diskette.

There are many reasons to causing the system booting-up with un-appropriated steps. Base on Microsoft support wizard on their WEBsite, there are many technical articles to help users with this subject, such as troubleshooting with VXD errors, virus, Fatal exceptions, etc., more details cover on each issue are descriptive and familiar with, and exclusively further to our support.

Q: System hangs-up after installing video driver.

Explain and Suggestion:

Today, most video drivers are developed for 32-bit processing and may require a channel to Code/Decode. Conflict between device drivers and TSR (terminate-and-stay-resident) programs will inverted the display, and are particularly effectual at crashing computer. The most effective way to check for conflicts is to replace with the original video driver, or delete and re-install the current video driver to the system.

Accomplishing IRQs (Interrupt Request Query) settings or troubleshooting the conflicts on hardware source may necessary. Most AGP video cards designed for Plug-n-Play, that means video card IRQ's setup which controls by main boards (motherboard) circuitry and BIOS. Physically pulling out other devices from system, and re-starts the computer. Confirm and modify your IRQ addresses with qualified computer technician.

Q: Multiple images or unreadable screen after loading video driver.

Explain and Suggestion:

There are a variety of reasons why the display might be distorted. One common reason is a monitor mis-match. Some older multifrequency monitors are unable to switch video modes without being turned off, then turned on again.

If the problem occurring in windows, make sure that you have loaded that proper video driver, and that the driver is compatible with the monitor being used. Try re-configuring your application software to use a compatible video mode. If problem persist in windows, load the standard generic VGA driver. The generic VGA driver should function properly with virtually every video board and VGA (or SVGA) monitor available.

If that is an unsatisfactory solution, you may have to upgrade to a monitor that supports the desired video mode.

Some new monitors are also synchronizing this problem because built-in DDC (Data-Digital-Channel) feature. Sometime that DDC automatically setup the display frequency without loading video driver. Try to turn it off, or change settings of monitor type in your system.

Q: Selection of color, resolution and refresh rate combination that always backs to default after restart the system.

Explain and Suggestion:

Accordingly, there must be a bug (defected source-code) in video driver, or in the system. Debug the source-code or fix the error in video driver, that should be done by the driver developer. Likewise, upgrade the video driver from the manufacturer or from the original software developer is necessary.

Frequently Asked Questions (FAQ)

Q1 Why do we need 3D graphics capability in our PC?

Answer

3D technology is becoming increasingly important (and common) not only in games, but also in other applications such as VRML, which allows 3D scene descriptions in Web applications. 3D technology is used for image editing, modeling, and an increasing number of in home and business applications. In games, as well as other applications, 3D acceleration not only allows better visual qualities and more realistic scenery attributes than software alone, but it also allows a higher frame rate, which translates into a more interactive experience for the end user.

Q2 What does Rendering Engine mean?

Answer

Rendering Engine generically applies to the part of the graphics engine that draws 3D primitives, usually triangles. In most implementations, the rendering engine is responsible for interpolation of edges and 'filling in' the triangle.

Q3 What does the set-up engine do in a graphics controller?

Answer

A set-up engine allows drivers to pass triangles in the form of raw vertex information; whereas, most common designs force triangles to be pre-processed for the rendering engine in terms of delta values for edges, color, and texture.

Q4 Why does a 3D graphics chip need to have both a rendering engine and a setup engine?

Answer

Any 3D application, a game, VRML, or modeling package, can benefit from 3D rendering. This is especially true of applications that uses texturing extensively, because texturing and texture filtering are very intensive operations at the pixel level in terms of CPU operations and demands for memory bandwidth. Without a set-up engine in a graphics controller, the CPU has to calculate the delta values for edges, color, and textures; the drivers need to handle ten (10) times more extensive data. This results in slower 3D pipeline operations between the CPU and the graphics controller.

Q5 If we use powerful CPUs, such as a Pentium 200, can a standard 2D graphics card achieve 3D performance?

Answer

Yes and no. Software rendering can take advantage of 'tricks' learned by force of necessity through years of trial and error. With such stratagems, the speed of software rendering for simple scenes can approach that of low-level hardware 3D rendering. On the other hand, as scenes become more complex (or frame sizes become larger), there are conflicts between using the CPU for high-level game logic, geometry, lighting, and rendering, all of which increase their demands. No current CPU or system can perform advanced quality-enhancements (bilinear filtering and alpha blending) in real time. Even general case texture mapping with RGB lighting is too much for the current CPU generation.

Q6 What does 'software 3D' mean?

Answer

Software 3D is generally used to mean using non-specific (2D) hardware in conjunction with the CPU to render for 3D applications. Some of these techniques allow usable 3D applications when high-powered and/or MMX-equipped CPU's are employed along with special-case software optimization techniques. As stated above, SW 3D can achieve credible results with today's (software optimized) applications, but the rising popularity of good 3D hardware at the consumer price level is inexorably compelling the public to expect hardware level scene enhancements and frame rates.

Q7 What is SGRAM?

Answer

Synchronous Graphics Random Access Memory (SGRAM) is a new and improved type of memory, custom-designed for graphics use.

Q8 What is the advantage of as compared to ordinary DRAM?

Answer

is now capable of running at much higher speeds than Fast Page Mode or EDO DRAM. Also, is able to execute a small number of frequently executed operations, such as buffer clears, specific to graphics applications, independently of the controller.

Reducing Warranty Claim Rejections.

To reduce the potential of incurring damages not covered by Manufacturers warranties, we strongly recommend the following:

read your manuals before installing peripherals and/or before making changes to the machines configuration;

ask your dealer if there are any known problems with the system requirements or installation procedures for any add-on products that your are purchasing;

buy industry standard products where compatibility issue are more likely to surface;

If you are unsure about installation for a new product, contact your dealers service department.

We believe it is important for you to know and understand what your warranty coverage provides and what it does not.

We also want you to be aware that most hardware warranties only relate to the function of the hardware. In most cases, no assurances are given by the manufacturer that the hardware item will work in conjunction with any other hardware item. If a computer product is not working because it is not compatible with another product, or because it has not been properly installed and set-up, the manufacturer does not pay for the service time. To help avoid these inconveniences, contact a professional consultant that one can help you determine the possibility of incompatibility issue before you purchase add-on or accessories.
