TV Tuner Card : What is it?
TV tuner cards receive television signals and display images on the computer monitor. They receive signals through a regular coaxial cable connector, which passes the signal to a tuner and decoder. An MPEG-4 decoder on the computer usually converts the signal into a viewable format. Most tuner cards come with tuner software, radio tuner, remote control, and infrared receiver.
Kinds of TV Tuner Cards include the following:
|PCI TV tuner cards|
- PCI TV tuner cards are mounted onto slots in the computer’s PCI expansion rack.
- They are commonly used for desktop computers and servers.
PCMCIA TV tuner cards
- PCMCIA TV tuner cards are shaped like credit cards and fit into the PCMCIA expansion in laptops and portable computers.
- They are more compact than PCMCIA, but usually have fewer outbound connectors.
USB TV tuner cards
- USB TV tuner cards are housed in a separate box that plugs into the computer’s USB port.
- They are simpler to install and can easily be transferred between computers.
|Parental control: Choose a TV tuner card with a parental control feature if children will be using the tuner. Look for one that blocks or secures adult channels, or logs failed attempts to access them. A timed session feature is also useful for regulating your child’s viewing hours.|
Compatibility: Choose a TV tuner card that supports all display formats, such as PAL, NTSC, and SECAM. For wider channel pickup, look for one that picks up analog, digital, and satellite signals.
