There are two common connections for domestic video that carry both video and audio. In Europe, the SCART connector has been popular for may years. It is a 21 pin connector that carries SD video with stereo audio. In a fully wired connection, it also carries return video and audio signals. The connector also handled control lines to integrate control of players and televisions. The connector has made little impact in North America and is now being replaced in Europe by HDMI.
HDMI is a digital video interface that also carries video and audio. It handles SD, HD and computer display formats. It is compatible with digital DVI connections although DVI does not support audio.

Does s-video have audio signal?
S-video is an interface standard for video signals only. It used two cables, one for a black and white image and the other for the color information. Audio needs to be routed on separate cables.
Does an S-Video cable also carry audio?
S-video cables carry two video signals. One carries brightness information (the Luma signal) and the other carries color information (the Chroma signal). Together they deliver a complete color picture. There is no audio carried by the cable, either as a separate signal or imbedded in the video signals. To get audio, another cable or set of cables will be needed. There are some multi-pin connectors that carry not only vide but audio and control as well. The SCART connector which is commonly available in Europe is one such example. This connector can carry a variety of video signals, two channel audio and some control lines as well. Most of the analog multi-pin connectors are being replaced by HDMI, a digital connection that carries all signals in a digital encoded format.
Does an S Video cable also carry audio?
S-video is a two part video signal carrying luma and chroma signals (Brightness and color signals). There is no audio signal in an S-video connection so the audio will need a separate connection to operate.
Can audio and video signals can be sent simultaneously over bnc cable?
BNC is a type of connector for co-ax cables. It is commonly used in the broadcast industry although seen far less in domestic situations. There are two ways that audio can be carried with a video signal over a single co-ax cable. The first is by using RF signals, as are used in terrestrial broadcasts and picked up by an antenna. Signals can be either digital or analog. The alternative is a broadcast digital signal called SDI (serial digital interface). SDI carries digital component video, audio and other control data and represents the best quality video signals available. The interface supports SD and HD signals and runs at 270Mbit or 1.5Gbit, depending on the resolution. Unfortunately, SDI is not seen outside broadcast facilities. Despite the ease of use and compact size of the cables, SDI does not support the copy protection that is demanded by content producers and so has never made it to domestic equipment.
Is it true that HDMI cables provide the best quality HD picture because the audio and video connections is in the same cable?
There is no truth in the statement. HDMI is an interface that carries digital audio and video signals. The image quality is dependent entirely on the quality and resolution of the signal that is delivered to the HDMI port by the video source. The HDMI connectors and cable carry that signal to the receiver but the cable does not change it in any way at all. DVI is compatible with HDMI other than the fact that there is no audio carried with the video signal. The video signal is identical to that carried by an HDMI cable and so this alone proves that statement to be false.
Does dvi support HD signal?
Yes and no. Domestic HD video uses the HDMI interface to carry signals. HDMI not only carries video but also handles audio and control functions. DVI is a similar interface and it entirely compatible with HDMI video. An image carried by DVI will be identical to that carried by HDMI. Unlike HDMI, DVI does not support audio and therefore is not generally accepted as an HD video interface.
What does a HDMI audio and video cable do?
HDMI is a type of video interface developed to carry high definition video signals. Additionally, HDMI will support standard definition video and carries audio as part of the signal. The cable provides a convenient method of carrying video, audio and control signals between devices without the need to use multiple wires. HDMI is also compatible with DVI, a video display interface for computer displays. Unlike HDMI, DVI does not handle audio so the compatibility is limited to video only. HDMI supports an encoding system known as HDCP. The encoding is designed to prevent unauthorized copying of video content and increasingly commercial content is using the protection system.

What is trunk line?
A trunkline refers to audio, and it represents an "address" that determines where the video and audio signals need to be directed to. A trunkline refers to audio, and it represents an "address" that determines where the video and audio signals need to be directed to.

What video types support or carries both analog and digital signals?
Analog and digital video signals don't mix well so there are few interfaces that handle both. HDMI is purely digital and has no capacity to carry analog signals. RCA, phono or scart connections are analog with no provision to carry digital video. In broadcast studios, 75 ohm co-ax cable is used almost exclusively to carry video. The same cables will carry analog video or digital video depending on what they are connected to. The decision to make broadcast digital signal run on the same cable as analog video has greatly smoothed the transition to digital broadcasting. As far as domestic video is concerned, the only dual standard interface that is recognized is the DVI connector. Primarily a computer display interface, it carries digital video but will also handle analog VGA signals on the same cable. Furthermore, the two signals can be carried simultaneously and can be the same or different images. As the digital video component of a DVI interface is compatible with the video component of HDMI, it can carry broadcast signals as well as computer display data so it can be described as a video cable. Note that although DVI and HDMI are compatible, DVI does not carry the audio element of the signal whereas the HDMI interface does.

Difference between data voice and video signals?
Audio: - An electrical signal that carries sound information is called audio. Video: - An electical signal that carries telivision picture information is called video.
Does an S Video cable also carry audio?
S-video is a two part video signal carrying luma and chroma signals (Brightness and color signals). There is no audio signal in an S-video connection so the audio will need a separate connection to operate.
What is an AV output?
An AV output is one or several connectors that output both video and audio signals from a device. They are found on terrestrial and satellite receivers, video recorders as well as some televisions. The output may be analog, using composite video, s-video, component or RGB with audio normally carried on a pair of connectors for left and right signals. Typically, domestic equipment will use RCA (phono) connectors although there are other connectors that are used in commercial equipment. Digital outputs are normally restricted to HDMI on modern equipment - a single connector that carries video and audio signals. DVI may also be called an AV connector but as it does not carry audio, it doesn't strictly fit the definition. Broadcast equipment uses a single co-axial connection on a BNC connector and carries SDI, a digital signal that can carry video, audio and other signals. Whatever the interface, it needs to be connected to a similar input to a television, a recorder input or similar device to link the output to any other equipment.
Does s video cables carry audio signals?
No. They only carry separated color signals.
