From Wikipedia, the free encyclopedia. Also present was a picture in picture function, but we could not get this feature to work. Aspect ratio can be altered to a few different settings traditional and wide screen but can not be defined by the user. Channels could be selected by using the mouse to click the appropriate buttons and the channels could easily be surfed using the channel up and channel down buttons. EMBM requires either specialized hardware within the chip for its calculations or a more flexible and programmable graphics pipeline, such as later DirectX 8. Unfortunately, because of the identical core clock and due to lower memory bandwidth, G was slower than G in games. Due to this lack of industry-wide support, and its toll on the limited graphics hardware of the time, EMBM only saw limited use during G’s time.

G’s 3D engine consists of 2 parallel pixel pipelines with 1 texture unit each, providing single-pass dual-texturing capability. There is also a timer that can be set to automatically record a specific channel at a certain time. This driver was a precursor to a fully functional OpenGL ICD driver, a quick development to improve performance as fast as possible by offering an interim solution. Matrox took the technology developed from the G project, refined it, and basically doubled it up to form the G processor.
The software can also decode closed caption information which is displayed on two black lines at the bottom of the live TV image. The new chip featured several new and innovative additions, such as multiple monitor output support, an all-around bit rendering pipeline with high performance, further improved 2D and video acceleration, and a new 3D feature known as Environment Mapped Bump Mapping.
With regard to its hardware, G’s triangle setup engine, called the “Warp Engine” ironically, was somewhat slower than the counterparts aboard the competition’s cards.

The TV image can only be set to. Matrox made it very clear that they were committed to supporting OpenGL, however, and development rapidly progressed. The 3D capabilities of G were identical to G G’s rendering pipelined uses what Matrox called “Vibrant Color Quality 2” VCQ2a functionality in which all internal 3D calculations are done with bit precision. Overclocking tests showed that the core was unable to achieve higher speeds than G even though it was manufactured on a newer process.
Eventually a native OpenGL narvel called “TurboGL” was released, but it was only designed to support several popular games of the time e. Perhaps the most notable feature of G is its ability to drive two separate monitors to display a single desktop.
There are no WDM drivers available for this card. It does this by improving on the 96 constant registers specified for by DirectX 8.

Unfortunately Matrox never described the functionality of this component in-depth so little is known about it. Hardware MJPEG capturing can be unstable but software compression, using a good video codec, gives much better results anyway.
Channels could be selected by using the mouse to click the appropriate buttons and the channels could easily be surfed using the channel up and channel down buttons. Where many cards were crippled by blurry output, especially as the matfox and refresh rate increased, the Matrox cards delivered very sharp and clear images. Views Read Edit View history.

Due to this mtarox of industry-wide support, and its toll on the limited graphics hardware of the time, EMBM only saw limited use during G’s time.
Once the record button is pressed, the stream is written to disk until it is stopped or available disk space is used up. It added some new features to DualHead that worked with Internet Explorer to make pages show up on both screens at once. Bthat are fully 4X compliant and run at the higher speed if the motherboard is capable as well.
Still images of live TV can be saved by taking a “video snapshot”, accessible via the camera icon on the on-screen remote. This prevented us from sizing the window to our liking but also prevented image stretching or skewing as a result of an altered aspect ratio.
Retrieved from ” https: The DualHead capability not only offered desktop widening but also desktop cloning two screens showing the same thing and a special “DVDMAX” mode which outputs video overlays karvel the second monitor. This is an evolution of G’s “DualBus”, which had been bit. Snapshots are taken of the channel and displayed on the screen until updated.

It was also equipped with a hardware transform and lighting unit capable of processing 20—30 million triangles per second. EMBM requires either specialized hardware within the chip for its calculations or a more flexible and programmable graphics pipeline, such as later DirectX 8. There was no skipping or other problems while time shifting live TV. It marvwl purely a Direct3D 6.
