Generally it isn't possible to send two video signals on a single wire although there are instances where it can happen.
Video over Ethernet allows multiple signals to be sent in packets although the nature of Ethernet means that the signals will each have a delay so synchronizing the signals may be difficult.
Video over CAT5 uses converters that take a video signal and modify it to run over a single pair of a CAT5 cable. Normally, two more pairs would be used for stereo audio. If mono audio is used, it is possible to run two composite video signals with audio down one cable. Note that video over CAT5 uses the same cable as Ethernet but employs a very different signal format to Ethernet.
Composite video signals use a single cable but in fact, the signal has three separate video components encoded into the signal. The signals are one for brightness and two for color information. Together they make up a full color signal and can be separated into the three components at the far end. Although the cable carries three signals, remember that they are all parts of the same color signal so this probably doesn't qualify as two signals.
Finally, cable broadcasters use encoding systems to allow numerous signals to be carried on a single cable. The one that enters a house to supply a cable receiver carries many signals with just one being decoded and output by the receiver. This takes complex hardware at both ends so is outside the scope of most home users.
What else can I help you with?
Does dvi cables carry sound?
No, DVI cables do not carry sound. They are designed to carry just video signals, therefore you will need a separate audio connection to hear the sound. If you have an HDMI connection, then you can use this to carry the video and the sound down the same cable.
Which type of port transmits both digital audio and digital video with a single connector?
A HDMI cable will send audio and video down one cable.
How do you know if you have a short in your Panasonic Theater system?
A short (where one wire touches another) in a speaker cable may cause the speaker to simply not work, but usually causes the Panasonic system to shut down. A short inside the Panasonic system is unlikely, unless something was dropped into the cooling vents. If it is still working, but one speaker is not, it could be a break in the cable or a blown speaker.

Larry the cable guy funny sayings about new guinea?
Larry the Cable Guy is known for his humorous, down-to-earth style, often mixing observational humor with playful stereotypes. While he may not have specific sayings about New Guinea, he might jokingly reference the country's unique wildlife or cultural quirks, delivering punchlines that highlight the contrast between rural life in America and the exotic nature of New Guinea. His catchphrase, "Git-R-Done," could be humorously applied to any situation involving adventure or exploration in such a far-off place.
Which type of port transmit both digital audio and digital video with a single connector?
A HDMI cable will send audio and video down one cable.
What is coaxial cable impedance?
Cable impedance is one of the characteristics that define how the cable will transmit signals. There are some simple and some far more complex descriptions of transmission lines on the Internet that describe the feature in more detail. For the normal user, it is sufficient to know that video signals over co-ax cable will use 75 ohm cable. Most data signals that use co-ax cable will use 50 ohm cable. Generally, the source of the signal will have an impedance equivalent to the characteristic impedance of the cable. Similarly, at the end of the cable, the same value of impedance is needed. When the cable is terminated properly, the signal will be transferred to the end of the cable without it reflecting back down the cable. It is the reflections that cause ghost images or smearing on a television image. As the length of cable increases, it becomes more important to make sure the correct impedance of cable is used with the correct termination.
Does dvi cables carry sound?
No, DVI cables do not carry sound. They are designed to carry just video signals, therefore you will need a separate audio connection to hear the sound. If you have an HDMI connection, then you can use this to carry the video and the sound down the same cable.
Which type of port transmits both digital audio and digital video with a single connector?

What is the function of a neuron in the nervous system and how does it receive signals from other neurons?
A neuron in the nervous system functions to transmit electrical and chemical signals. It receives signals from other neurons through its dendrites, which are extensions that receive incoming signals. These signals are then integrated in the cell body and transmitted down the axon to other neurons.
Can you use a standered AV cable with yellow red and white to carry a component video signal through YPbPr?
Yes you can, but the cable isn't really right for video signals. Even the composite video signal that is normally carried by one of the three cables suffers over a long length. The best thing to do is to plug it in and try it. If vertical edges on the image appear slightly smeared, it may well be down to the cable and a new cable is called for. Have no worries - you won't damage anything by using the cable. The right cable to use, if you have a choice is 75 ohm coax. RG59 and URM70 cables will do the job although there are many others with higher spec (and price) that you can choose from. If you have to buy a pre-terminated cable, then choose the fattest cable you can find. It's not a scientific way of choosing the cable, but the diameter is normally an indicator of the quality of cable.
What is the different between s video cable and ypbpr cable?
S-Video is a type of composite video signal. The 4 pins are Chrominance, Luminance, and 2 grounds. Your standard composite video cable combines Chrominance and Luminance into one signal, which is then separated again by the TV. An S-video cable removes this step. The "y, pB, pR" cable set is known as "component" video. this cable goes one step further than S-Video, breaking down the Chrominance signal to individual colors, using Red (pR), Blue (pB) and Luminance (y). The TV then uses additive and subtractive methods to determine Green.
When was the first cable tv invented?
Cable TV was invented as a response to poor over the air reception. In 1948, companies in Arkansas, Oregon, and Pennsylvania started sending TV signals down coaxial cables.
How do you locate underground cable fault?
Time Domain Reflectometers can be used to locate where an underground cable fault lies. Time Domain Reflectometry (See wikipedia) is a measurement technique to identify the location using reflected signals sent down the cable line.
Could you use a stripped coaxial cable as a antenna?
Yes, a stripped coaxial cable can be used as an antenna, but it may not perform as well as a purpose-built antenna designed for that specific application. The length and diameter of the cable, as well as its impedance, will all affect its ability to receive or transmit signals effectively. It may work in a pinch, but for optimal performance, it's best to use a dedicated antenna.
What is a svideo cable for?
A s-video cable provides a connection for Super Video, which is a higher quality video signal than the more common composite video (usually the yellow phono jack marked Video). The Super Video signal provides two components of the composite video signal separately for better resolution and color rendition. The two components, luminance (Y) and chrominance (C), are carried on two parallel coaxial wires in the s-video cable. The four pins in the connector are for Y, Y ground, C, C ground.
What is down converter in satellite communication?
A down converter in satellite communication is a device that converts high-frequency signals received from a satellite into lower frequency signals that can be processed by ground equipment. This process involves mixing the incoming signal with a local oscillator signal to produce intermediate frequencies (IF) that are easier to handle and transmit. Down converters are essential for demodulating and decoding the signals for various applications, such as television broadcasting and internet services. They play a crucial role in ensuring efficient communication between satellites and ground stations.
