Home Theater Cords And Connectors

When you are setting up your high definition home theater, you will find a number of methods to connect your devices. We can go over a few now. The first is component video. This caries an analog video signal which is separated into three separate channels. The first two channels carry information in regards to color. The third carries information about luminance. These cables use RCA connectors. S-video is another way to hook your devices up to one another. S-video uses a four pin connector and one cable to transmit an analog signal. The third way is DVI or digital vidual interface. This uses a 29 pin connection. It's the same connector you see when you hook up your computer monitor. Unlike the first two methods we discussed, DVI will carry digital signals. In the early days of high definition television, we relied on DVI. It came into the consumer market before HDMI did, and since both systems use the very same TMDS protocol, they are compatible with one another. All you really have to do is connect your HDMI cable to a passable adapter in a DVI port. There are other similarities between HDMI and DVI connectors. Both HDMI and DVI us a grid of pins to get the signal off of the cable into the intended device. The DVI connector has 29 pins while the HDMI type A connector has only 19. DVI connectors will also have that pair of screws that are used to hold it to the device. Like I mentioned, these are the same connectors used with computer monitors. HDMI plugs do not have this extra feature and those that enjoy HDMI have complained about this. This is because of the extra strain it puts on both the connectors and the circuitry of the device. There is also a min version of the HDMI connector. This is used on devices that are too small for the larger size like digital camcorders. There is a smaller version of the 29 pin DVI connector as well, but most users will just go with the HDMI option. The signal moves from twisted copper wire into the HDMI connectors pins. Six pins carry audio and video channels. The TMDS clock allows devices to sync up their incoming data and that takes up two more pins in the connector. Each pair of pins on the connector has a shield. There is also another wire that will protect your interface from the next one over so the signal does not get mixed up. These channels with the clock and the shield compose most of the cable pairs you will find in an HDMI cable.
