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.
The most straightforward use of the device is to extend the range of the signal without degrading it. Most cables have a practical limit of five meters. Better quality cables extend the range to at most 15 meters. If there is a need to go beyond manufacturer recommended lengths most technicians specify the use of a repeater to join two cables without sacrificing signal quality.
The basic device will have two ports for input and output. The signal that is received is reassembled by the circuitry of the device. The data that was rebuilt is then sent to the output port.
The unit can be daisy chained thus allowing very long cable runs. When you use this deice, you can pass unsightly cables through walls and ceilings. Your entertainment room will look cleaner and more impressive.
As said earlier, the device allow longer paths for data transmission. But exciting new uses are being created for the device. Some repeaters add something to the signal before it is sent to the output connector. Special effects like surround sound, equalization, and video effects are just some of the things that are happening. But when devices gets complicated, we all know that more problems will show up sooner or later.
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.
