ACTIVE VIDEO COMPONENTS
Active video components offer a wide range of possibilities: whether you want to transfer a video source to multiple output media via a video splitter or play multiple video sources with a video switch on one output device. Especially active video extenders become more and more important in times of HDMI™ 2.0 and their more rigorous length restrictions. 4K Resolutions are hardly realisable in lengths of more than 10 m with conventional cables. If the link pass 15 m, active video extenders are particularly suitable. They can bridge large distances with modern network cabling and are available in several variants for different interfaces.
Until recently, the cabling of the video network was predominantly guaranteed by means of pure video cabling. For solutions to extend the length limits of the current video cables, proprietary systems were used. Disadvantages of these systems, however, include possible losses in quality, due to a compression of the data or the incompatibility with 3rd party manufacturers. Added to this, 4k resolution is gradually becoming more and more common in our everyday lives, with the result that higher demands are placed on bandwidth, which also brings this system to its limits. The HDBaseT™ Alliance has introduced HDBaseT™ technology to the market in order to provide a connectivity standard to solve those problems and provide many other benefits. HDBaseT™ builds on a so-called 5Play ™ system, which combines the function of transmitting video, audio, Ethernet, control signals and power over one single network cable. In this process, one network cable of Category 5e or higher is used as the transfer medium, which can transmit the data and power to a distance of up to 100m.
Audio & Video
Transmission of uncompressed audio and video data in Full HD (2k) or Ultra HD (4k) resolutions without any delay. Support for all features of HDMI 1.4a.
The transmission of the data is ensured via a 100Mbit connection (100Base-T Ethernet), whereby the connection is bidirectional and allows the devices to communicate with each other.
Native USB2.0 support, for input devices, touch screens, mass storage, etc. These HDBaseT devices would also take over functions that had previously been reserved for KVMs.
Support of control signals such as CEC, bidirectional RS232, IR or IP. For the control and simple installation of terminal devices.
Power over HDBaseT™
HDBaseT™ enables power from connected devices of up to 100W. This builds upon the 4PPoE (4 Pair PoE, IEEE802.bt) standard, which allows to transmit power up to 25W over one twisted pair. In conjunction with HDBaseT™, the technique is called PoH. As a result, devices can be operated over long distances without a power supply.
