HDBaseT is a connectivity standard for uncompressed HD multimedia contents. HDBaseT 2.0 is the latest technology published by HDBaseT Alliance for a complete multimedia entertainment center for transmitting 5PlayTM digital multimedia contents via twisted-pair copper cables.
HDBaseT facilitates a cost-effective and simply plug-and-play solution using standard twisted-pair cables and RJ45 connectors in the categories Cat. 5e, 6, 6A, 7 or 7A** for a fully comprehensive multi- media system.
HDBaseT comprises several functions, marketed under the name 5PlayTM. They form the base for HDBaseT. 5PlayTM groups together uncompressed Full-HD or UHD video contents, audio, 100BASE-T Ethernet, energy supply by Power over Ethernet (PoE) respectively Power over HDBaseT (PoH) of up to 100 W and various control signals in a single technology. Communication between the devices (TV, the sound system, the computer and other electronic entertainment devices) and access to stored multimedia contents (music and video streaming) is made possible by 100 Mbit Ethernet (100BASE-T Ethernet) via a standard twisted-pair copper cable over a distance of up to 100 m. Thus, HDBaseTTM can use a cost-efficient cabling infrastructure: different cables for a new installation or retrofitting are avoided and in new buildings the required cables may already be present, since all 5PlayTM functions are transmitted via a single cable.
Since HDBaseT comprises the 5PlayTM functions and thus also in particular the transmission of highresolution video contents, the focus in the previous chapter was placed especially on the enormous data volumes for these HD and UHD contents. The reason for this is the cabling infrastructure, which comes up against its limits in terms of transmission capability and length restriction. This is why, here at HDBaseT, the decision was taken in favor of twisted-pair cables. Their use and specifications for different HDMI versions and twisted-pair categories will be explained in more detail in one of the following chapters.
**Cabling system, category and class are described in ISO/IEC 11801.
