What is the repetition of HDMI®?
High -resolution multimedia interface (HDMI®) is a preferred High -resolution interface (HDTV) and audio visual products such as DVD players, Bluray® and gaming devices. The interface sends high resolution, digital video and multi -channel digital sound over one efficient cable. While the HDMI® specifications do not contain HDMI® transfer restrictions via the cable, the cable design itself leads to signal degradation. Installations that require longer cable lengths can benefit from using the HDMI® repeater.
October 17, 2008, HDMI® cables are marked according to one of two specifications: Category 1 certification cables or category 2 certified cables. Category 1 cables are "standard" cables, supportive resolution up to 1080i, while category 2 cables are "high -speed" cables that support 1080p and then (eg HDMI® 1.4. 1080p for 3D TV).
are constructed certified by the needed qualityOU for faithful delivery of the signal over the length of the cable, but the length of the cable is limited, usually to 16 feet (5 m), or for higher quality cables, 49 feet (15 m). Longer cables are available, but depending on quality, they can eventually deliver a weak signal that represents problems such as freezing or pixilation. For installations that require longer cable lengths, it could be a better option to connect with the HDMI® repeater to strengthen the signal to prevent degradation.
Repeater HDMI® is a separate device that can be powered by its own AC power source or 5 V charging in the HDMI® cable. Connect the incoming HDMI® source to the input port and another HDMI® cable to the output port. The repeater regenerates the incoming HDMI® to ensure the integrity of the signal via the secondary cable, allowing its own length to be. The actual lengths are particularly useful in the carriage of kabelly through walls, floors or ceilings. If necessary, the product can also work in a series. Depending on the model, the HDMI® repeater may be small as a connector or adapter.
Repeater HDMI® should comply with disturbed protection against copyrights to video rights or high digital content with high bandwidth (HDCP). HDCP encodes movies to avoid piracy. In order to work properly, the source and display must also pass the HDCP content.
Repeater HDMI® can also be referred to as HDMI® amplifier, but not every HDMI® extension increases or amplifies the signal. Some extensions only equalize or clean the signal.
HDMI® Repeatters ranges from about $ 35 in USD (USD) to more than $ 100. Smaller models of adapter types that do not require external power and LED function indicators are generally in the middle of the price. Most models specify how far the signal can be extended, usually 100 feet (30.48 m) and 200 feet (60.98 m).
