What Is PCI Multimedia Device?
A PCI multimedia device is computer hardware that enhances the ability of your computer to deliver a more complete audio and visual experience with features, such as animation, TV, video, audio and graphics. A PCI multimedia hardware can greatly extend the way you use a computer in business, home office or entertainment applications.

History
-
The development of PCI multimedia devices is related to three technological events. First, in 1991, the Intel Corporation's launch a new industry standard for connecting hardware to the computer called the Peripheral Component Interconnect (PCI) bus. This equipment allowed PCI multimedia hardware to connect directly to the computer's central processing unit (CPU) through the use of an electronic component call a bridge.
The next development that played a key role in the proliferation of PCI multimedia devices was Intel's Plug and Play (PnP) technology eliminated the need to configure devices to work with your computer. The third event was the release of Microsoft Windows 95 operating system, which provided the technical support needed to take advantage of PCI (multimedia hardware) and the PnP features. In its entirety, these developments meant you no longer had to be a geek to connect equipment to your PC.

Function
-
Most personal computers have multimedia hardware built right into the motherboard. However, the functionality is typically limited and includes basic input/output for microphone and speakers. There is also a line input for recording and playback of audio. However, if you enjoy gaming, are active with video editing or if you will be using graphic-intensive software applications, you'll need a PCI multimedia device. For example, a PCI multimedia device (sound card) permits you to use your personal computer to operate a surround sound home media, including your stereo, DVD recorder and flat screen TV.
Types
-
Many types of PCI multimedia devices exist, including TV tuners, graphic cards, (video cards), audio cards. PCI TV tuners cards give you the capability to pause and rewind live television. You can also record programs to your hard disk drive. Users can also watch full-screen video on their computers, or simultaneously open a miniature window on your screen to keep tabs on your favorite show and surf the Internet.
A PCI video card conveys the data it receives from your software applications and outputs the text and graphics you see on your monitor or LCD. One of the main features of many video cards is its graphic processing unit (GPU) and random access memory (RAM). Having its own microprocessor and RAM abolishes the need to rely on the computer; the system can now focus its resources on other jobs.
Features
-
One of the main features of a PCI multimedia device is the relative ease in getting the hardware up and running. All the user is required to do is connect the hardware to the compute. The system takes over from there. The operating system detects the hardware, identifies the Plug and Play ID number of the product and figures out what resources the device will need. The necessary driver is automatically downloaded and installed; PnP also managed power resources, such as hibernation or system shut down.
Benefits
-
One of the main advantages of a PCI multimedia device is the ability it has to enhance digital audio inputs and outputs. This enables users to connect CD and DVD devices that have digital connection features. Since the data transfer is digital, the sound quality is just as good as the original audio. PCI multimedia devices that have Musical Instrument Digital Interface (MIDI) component, or MIDI jacks, not only allow musicians to listen to music, but also compose synthesize music using their personal computers.
