各种视频处理卡的功能与接口概述

Things to keep in mind cont.
• Running 2 Video Cards at once o Depends on the chipset of your motherboard Scalable Link Interface (SLI) Nividia chipset that allows you to run multiple videocards Crossfire is a Intel chipset that allows multiple video cards to run Need a USB 2.0 Display Adapter to run MultiMonitor while using SLI/Crossfire
PCI AGP or PCIe
Video/Graphic Cards
PCI AGP • Peripheral • Accelerated Graphics Port cபைடு நூலகம்mponent interconnect • Originally created • Uses bus for 3-D computer architecture graphics • Can be integrated • Provides dedicated circuit fitted onto pathways between the mother board the slot and the processor or an expansion card • Point-to-Point • Coexist with other connection expansion buses allowing higher • "Plug and Play clock speeds
I/O Cards
• Input/ Output (I/O) cards are cards that provide some sort of external connectivity.
o
USB, Parallel, SATA, SCSI, and NIC/WNIC cards Although often times USB, Parallel, and SCSI cards are very much out of date. Now integrated in with the Motherboard. Often times I/O Cards are labeled as "Low Profile Cards" which are cards that fit in smaller computer towers.
Video Capture Cards
• Video capture cards are designed to plug directly into expansion slots in personal computers and servers • All comply with one of the popular host bus standards (PCI, AGP, and/or PCIe) • Proper hardware and software are necessary to transport the captured video to the computer • Problems arise with dropped frames, problems synchronizing audio and video, and poor quality play back.

Different types of Hardware for your computer
• Adapter Cards o Graphics Cards o Sound Cards • RAID Cards • eSATA Cards o I/O Cards • Wired And Wireless Network Cards • Capture Cards
o
SCIS: Small Computer Interface System • Pronounced "scuzzy"
• Involve chains, IDs, and termination • Chains: a series of SCSI devices working together through a host adapter (the host adapter provides the interface between the SCSI chain and the PC) • Categorized as internal and external devices • IDs: range from 0-15, doesn't matter which device gets which number and numbers can be skipped but none can be the same • Termination: Only terminate the ends of the SCSI chain. Some devices come automatically able to terminate others need to be set. Termination is used to prevent the electrical echo.
Adapter Cards
• An Adapter Card (which is also known as an expansion card) is a circuit board that's put into a expansion slot of a motherboard to give more functionality to the computer. o The main focus of an Adapter card is to provide features that are not normally offered on some motherboards Graphics Cards Sound Cards Network Cards
Overclocking and Benchmarking
• Overclocking- Process of running the video card at a higher bits/second than it was meant for. It's used for minimizing/maximizing performance.
PCIe • Express • Replaced AGP and older PCI versions • Uses Point-toPoint serial connection rather than shared parallel communication • Not compatible in PCI slots • Multiple data lanes
RAID Cards
• RAID Controller Cards are pieces of hardware dedicated to controlling RAID functions. o RAID chips can be integrated into the Motherboard o RAID Controller Cards will come in the form of PCI, or PCIe • RAID 0 and RAID 1 can be setup either by software, or hardware. RAID 5 is setup by hardware.
Sound cards, TV tuner cards, Capture cards
Sound Cards
• Sound Cards (aka Audio Cards) is an Adapter Card that enable's the input and output of audio signals between the itself and the computer. o Multiple inputs: Pink- Microphone input Blue- Audio input Green- Audio output Front speakers Headphones Brown- Audio output for Right to Left Speaker Black- Audio output surround sound speakers Orange- Audio output for subwoofer
• Benchmarking- Tests a video card performance and then gives results to compare to other benchmarkers. o http://www.videocardbenchmark.net/

Things to Keep in mind
• Bigger Monitors with higher resolution (while running the same program) need better video cards • Make sure your Power Supply has enough power to support your Videocard • Making sure your output is supported o Blue Ray will need a video card which supports: HDMI HDCP (High-Bandwidth Digital Content Protection) Allows you to stream blue ray from your Video card to the TV)
TV Tuner Cards
• Computer component that allows television signals to be received by a computer • 4 components are required to make this happen 1.A tuner device 2.An antenna or cable connection 3.A tuning application 4.Some sort of program guide
Graphics Cards
• A graphics card (aka Video Adapter, Graphics Accelerator Card, Display Adapter, or video card) is an expansion card that generates output images to a display monitor. o Added features to a graphics card 3D rendering video recording MPEG-2/-4 decoding (compressing of videos) Light pen TV Output Multi-Monitors
