A Tutorial On How Computer Video Adapters Operate
When someone is checking out a video clip or feature, he/she are not familiar with the forces working behind the cover to bring that video to their screen. There is a lot more than just analyzing, playing, and displaying the images to the screen. Whether it is a simple text animation or a complex 3-D rendering, video cards make it possible to see a video of any kind.
A chip for video is sometimes referred to as: display adapter, graphics card, or graphics accelerator card. In short, the machine picks up the information and sends it to this card, in the on-board slot, to calculate the information and return a display to the monitor. This process happens seamlessly and the person watching the screen has no idea of the many parts that are processing and translating this data.
Video cards usually have input areas in the back to support various devices or media players. These ports basically take in the video from another source and display it to the monitor or screen. Some of the most well-known ports include:
* Video Graphics Array (VGA) - A VGA is ancient and is not seen in later model machines. It looks similar to a rectangle or circle slot with holes in the middle. This is the first kind of video input/output and is not used anymore because the quality is substandard.
* Video In / Video Out (VIVO) and S-Video - This series of sockets allow for 3-D rendering by translating the data. These types are more widely used today and support a perfect view, LCD, and plasma. The installation point looks round and has dots in the inside. Most computers and televisions label this as S video.
* High-Definition Multimedia Interface (HDMI) - This interconnect for digital audio and video is a bit more high-tech and supports gaming and DVD playing. This type of connection also restricts copying of copyrightable materials.
* Display Port - The display port is the newest technology in video connection and is known to be capable of putting all other connections to rest. It supports seamless video rendering without interruption.
Whichever the plug input/output used, computers all read and process video on a chip. The chip set of the card includes components that make it work. These components include: video bios, video memory, and RAMDAC (Random Access Memory Digital to Analog Converter). The video bios is a simple rule book of how the machine is to translate and display video. The video memory then starts to help streaming. Lastly, the RAMDAC translates the analog signal to a digital one so the machine can show the video. Although some computers no longer need RAMDAC, due to the invention of monitors with RAMDACs already in them, though all machines still need it to run the video clip.
Not all computer users who are accustomed to playing videos know what is happening behind the scenes. Most users value being able to see a video at the click of a button. The processes aforementioned calculate so quickly that it is impossible to see by the naked eye. However, many gadgets and pieces are hard at work to bring the clarity of video.
