Yes, it can.
Assuming the video cable has the right connectors, probably RCA type (phono connectors) then it can be used for audio signals. In fact, some high end audio interlinking cables use video cable because it is claimed that they work better than standard audio cable. (Note that this is the subject of fierce debate among audiophiles and there is no proof that video cable is an improvement on audio cable for audio signals) Using audio cable for video can also be done up to a point. For short connections, up to a few feet or a couple of metres, an audio cable will work just fine. As the length of the lead increases, the cable will begin to interfere with the video signal and cause loss of definition or ghost images. Substituting the cables will not cause damage to equipment, so it is safe to try it. If it looks or sounds like it works, then it works!
The type of cable used to connect audio video equipment will be dependent on whether or not one is using HD or not. If one is using HD equipment, then an HDMI cable can work. If not, then look for an S-Video cable. A local Best Buy can personally help one in their decision.
For short signal runs, audio cable can be used for video without any issues. As the length of cable increases, it become more important to use cable that is designed for video signals. For most video signals, this will be a 75 ohm co-ax cable such as RG59. There will only be a noticeable difference in quality once the cable length exceeds 10 to 20 feet.
I can be used to replace the standard 3.5mm audio cable, yes
Use the s-connector to improve the picture from that of a simple yellow video connection. The improvement will enough you can see it on the screen. This cable carries no audio.
An optical audio cable is used to transmit digital audio (AC-3) signal from the source to the receiver, such as from a DVD player to a digital audio amplifier/receiver. You can transmit 5.1 dolby digital or DTS surround sound with an optical audio cable, same as digital coaxial audio cable.
A scart cable is a multi-pin video and audio connector common in Europe. The cable can carry audio, composite video, S-video, RGB and component video as well as a limited amount of control data. Used for connecting video recorders to televisions, it also supports return video )i.e from the television to the recorder). The connector was only used in domestic video installations and never in a commercial environment. The connector was prone to reliability problems as the weight of the cable was sometimes able to dislodge the connector. Scart connectors are now giving way to HDMI and becoming less common on new equipment.
HDMI connectors (they aren't slots), are inputs or outputs for high definition video and audio used by modern televisions, cable and satellite receivers, game machines, computers and other devices.
Audio connectors and video connectors are electrical connectors for carrying audio signal and video signal, of either analog or digital format. Analog A/V connectors often use Shielded cable to inhibit radio frequency interference (RFI) and noise. They use connectors such as SPEAKON, XLR, TRS and RCA.
It can be video, audio but mainly its video and audio together. Found on Wikipedia
S-Video to RCA jacks cost around 13 dollars.If you prefer you can use a video switch,a little box used to switch between video sources.You just put the S-video in one of the inputs and the RCA jacks in the output,select the right button and you're good to go.
HDMI is High definition multimedia interface. It is a cable that sends both audio and video to the TV. It is used for HD and video games. Newer TVs have a port in the back for the plug-in.
