S-Video ports and AVI ports are used to connect a computer to a monitor/television screen. S-video usually works with older television sets and some monitors. AVI used to be the most common way to connect a computer (desktop or laptop) to a monitor. Currently HDMI and DVI dominate the commercial market.
As for uses: people use them for dual/multi-monitor displays; to extend their workspace. You can also connect your laptop to a better monitor/television and then you can watch a video in better quality.
Hope this helped!
S-video is better than the composite video when output to a television
An S-Video Port
Composite video out has better performance than S-Video.
S-Video is an analog port, not digital, so "serial" and "parallel" terms do not apply to it.
Composite video would be worse then S-Video. S-video separates out the Chroma and Luma signals which means there is less cross-talk between them producing a cleaner analog picture.
An S-Video Port.
The S-video port on a Sony Vaio allows it to output to older televisions and projectors. This is helpful when doing presentations where a larger screen is needed.
No, you should use a bus to connect a capture card to a computer. If you're asking if you should use the S-video port to connect the video device playing the video you want to capture to the card... sure, it's one option, and if your capture card and video device support S-video, it's likely to result in a higher-quality image than using the composite video port will.
what is another name for a video port?
No, unless your laptop has a TV-in or S video in port
An S-Video port is typically a round, 4-pin or 7-pin connector, resembling a small circular socket. It has a characteristic design with a metal casing and a small notch to ensure proper alignment when connecting. The pins inside the connector transmit video signals separately for better quality compared to composite video connections. S-Video ports are commonly found on older televisions, video equipment, and some computer graphics cards.
This cannot be done. The LPT port is a digital parallel printer port used mostly to interface with printers. The LPT port has a very low data transfer speed and is considered by many to be obsolete. The S-video is an analog port and sends a signal similar to a composite video signal. The two are apples & oranges, and there is no known hardware which can make that conversion. Nor will there likely ever be.
