The Digital Display Working Group (DDWG) has a specification which limits the approved HDMI cable length to 15 meters (approximately 50 feet.) for delivering a full HDTV signals. The HDMI In-line Signal Amplifier Dongle digital interface attaches to the display side connector of an HDMI cable and not only amplifies the signal but it cleans out any noise or digital artifacts from the data and retransmits the picture to the source display. The result is that a high definition video up to 1080p, compressed or uncompressed multi-channel audio, and intelligent format CEC command data can be delivered to 150 feet away from the source component all from one in-line adapter. No external power supply is required as the HDCP compliant amplifier with the adapter receives power from the connected HDMI cable while remaining entirely transparent to the source component and the display monitor. An LED power indicator even lets you know that the device is powered and working properly.
