What Does An HDMI Repeater Do
HDMI is the best thing now for home entertainment. With just one cable, it allows several signals to pass through simultaneously in their original, unaltered formats. While the specification does not state that HDMI has a limited range, differences in cable manufacturing means that there is a practical length of the wire that is used to connect say a blue ray player to a flat screen monitor. To overcome this limitation, different manufactures are making HDMI repeaters.
Easily the most obvious use for the device is to extend the distance between a signal source and a player. Lower quality cables have a signal limit of 5 meters while better quality ones allow 15 meters. Technicians when asked about how to extend the distance usually recommend a repeater.
The device will have an input and output port. The cable that needs to be extended is connected to the input port. The circuitry inside the repeater rebuilds the signal and is passed to the output port.
It is theoretically possible to daisy chain two or more devices. Because lengths in data cable can be overcome when the device is used, unsightly cable runs can be avoided. This makes it possible to hide cables inside the ceiling and walls. A cleaner look in your entertainment area is achieved.
There are other more exciting uses of the device. As stated earlier, the circuitry in the unit reassembles the signal. Some devices add something to the signal that is being rebuilt. These are usually effects like surround sound and equalization. However the more sophisticated the unit becomes, the more problems there will be.
An HDMI repeater is an effective solution to overcome the common problem of limited cable length. The device is easy to use and cheap. Equalization and surround sound are not normally associated with repeaters but when they become part of functions of the device, it creates excitement in the market that is good for consumers like us.
