WHAT IS HDbaseT?
HDBaseT™ technology has truly revolutionised the market for AV distribution sending all these signals over a dedicated single CAT cable infrastructure. HDBaseT products are now being specified as the standard in most commercial and residential AV systems.
Phd Solutions have embraced this technology and have manufactured most of our connectivity products based on HDBaseT and HDBaseT-Lite.
Our engineers have been at the forefront of this technology since its launch. Through innovative integration of HDBaseT they have developed a comprehensive range of leading edge connectivity products.
The HDBaseT Alliance, incorporated on June 14, 2010 by Samsung Electronics, Sony Pictures Entertainment, LG Electronics and Valens Semiconductor, was developed to promote the HDBaseT technology originally created by Valens.
HDBaseT is a connectivity standard for whole-home and commercial distribution of uncompressed HD multimedia content. The cornerstone of HDBaseT technology is 5Play™, a feature set that converges uncompressed full HD digital video, audio, 100BaseT Ethernet, power over cable and various control signals through a single LAN cable.
The HDBaseT 5Play™ feature set enables delivering the following over a single 100m / 328ft CAT5e / 6 cable:
Video
HDBaseT delivers full HD / 3D and 2K / 4K uncompressed video to a network of devices or to a single device (point-to-point ). Since the video is passed through the HDMI chipset, HDBaseT supports all key HDMI 1.4 features, including EPG, CEC, EDID, and HDCP. The unique video-coding scheme ensures the highest video quality at zero latency.
Audio
HDBaseT audio is also passed through directly from the HDMI chipset. HDBaseT audio supports all standard formats, including Dolby Digital, DTS, Dolby TrueHD, and DTS HD-Master Audio.
Ethernet
HDBaseT supports 100Mb Ethernet, enabling communication between televisions, sound systems, computers, and other CE devices as well as access to any stored multimedia content (such as music or video streaming). HDBaseT also supports Ethernet Fall-back Mode, which enables seamless integration between aHDBaseTdevice and an Ethernet-only infrastructure. In such a case, only the Ethernet capabilities of the connection are enabled.
Control
HDBaseT enables multiple control signals for multiple purposes: Consumer Electronic Controls (CEC), Recommended Standard (RS)-232, USB, and infrared (IR). IP control is also enabled due to the support of an Ethernet channel. HDBaseT’s wide range of control options provides manufacturers with virtually endless opportunities.
Power (PoH)
Up to 100W of DC power can also be delivered over the same CAT5e/6 cable. This major aspect of 5Play provides the freedom to place equipment where you want it and not where an available power source happens to be installed.
HDBaseT™ In-Depth
The Valens HDBaseT™ offering consists of two complementary chips. A transmitter chip is implemented in the HD source device (e.g. Blu-ray player, STB). A receiver chip is implemented in the HD sink device (e.g. HDTV, projectors).
HDBaseT™ relies on Pulse Amplitude Modulation (PAM). Basically, this is the same technology that is used to code Ethernet signals into twisted pair cabling, where digital data is represented as a coding scheme using different levels of DC voltage at fairly high rates. However, HDBaseT™ uses a patented proprietary version of the PAM modulation, enabling its vast feature-set to be converged into a up to 100m single CAT cable, without the electrical characteristics of the wire affecting performance. It is important to note that, while HDBaseT uses the same coding technology as Ethernet and have an Ethernet channel, it is neither Ethernet nor packet based. It just relies on the same cabling, thus providing the inherent benefits of the cost-effective CAT infrastructure.
WHAT IS HDbaseTLite?
Valens Semiconductor developed a cheaper version of the original HDBaseTchipset
The cornerstone of HDBaseTLite technology is 3Play™, a feature set that converges uncompressed full HD digital video, audio, power over cable and various control signals through a single LAN cable.
The HDBaseT3Play™ feature set enables delivering the following over a single 70m / 230ft over 6 cable:
Video
HDBaseT Lite delivers full HD / 3D and 2K / up to 1080P over 70m / 230ft . Uncompressed 1080p@60Hz@36 bits, 1080p@60Hz@48 bits, 3D, 4K x 2K up to a distance of 40m/150ftto a network of devices or to a single device (point-to-point ). Since the video is passed through the HDMI chipset, HDBaseT supports all key HDMI 1.4 features, including EPG, CEC, EDID, and HDCP. The unique video-coding scheme ensures the highest video quality at zero latency.
Audio
HDBaseTLiteaudio is also passed through directly from the HDMI chipset. HDBaseT audio supports all standard formats, including Dolby Digital, DTS, Dolby TrueHD, and DTS HD-Master Audio.
Control
HDBaseTLite enables multiple control signals for multiple purposes: Consumer Electronic Controls (CEC), Recommended Standard (RS)-232, USB, and infrared (IR). IP control is also enabled due to the support of an Ethernet channel. HDBaseT’s wide range of control options provides manufacturers with virtually endless opportunities.
The HDBaseT4Play™is also a feature of some HDBaseTLite products, this adds Power over the Cable (POH) to the 3Play™ feature set.
Power (poh)
DC power can also be delivered over the same CAT5e/6 cable. This major aspect of 3Play provides the freedom to place equipment where you want it and not where an available power source happens to be installed.
DOES HDbaseT TRAVEL ON AN ETHERNET NETWORK?
No. Although it uses the Ethernet jack (RJ-45) HDBaseT is based on a different protocol that standard Ethernet equipment can’t work with. Future generations of HDBaseT will include HDBaseT switches that will allow HDBaseT networking.
DOES HDbaseT Support 4K?
Yes. HDBaseT is the only standard for delivering UltraHD 4K 60 (4:2:0) video up to 70m long. New UHD sources like the new Ultra Bluray players will require all connecting equipment in the HDMI chain all the way through to the display (TV) to be HDCP 2.2 compliant to enable a UHD image to be displayed.
HOW IS HDbaseT TECHNOLOGY DIFFERENT TO OTHER TECHNOLOGIES?
Unlike other HD distribution technologies currently available, HDBaseT is the only technology that enables long distance wired connectivity up to 100 meters for uncompressed full HD multimedia content and up to 100 watts of power via a single cable. HDBaseT is optimized for video applications and can connect all HDBaseT-enabled home entertainment devices by providing the 5Play convergence. Furthermore, HDBaseT technology has the capacity to deliver double the resolution available today, a component necessary for 3D integration and future 2K and 4K formats. Other existing solutions also require a specific cable and/or a new proprietary connector while HDBaseT utilizes the existing Ethernet infrastructure.
WHAT IS HDbaseT2.0?
HDBaseT 2.0 Brings Pro-AV Quality and User Experience to Consumers’ Homes
HDBaseT 2.0 is the latest specification released by HDBaseT Alliance in August 2013. The new specification introduces HDBaseTHomePlay feature set that, based on the HDBaseT 5Play capabilities, will make it simpler and more cost-effective for consumers to turn their entire homes into multimedia entertainment centers. HomePlay features an elegant, affordable plug-and-play solution that will allow the average consumer to enjoy the same multimedia benefits of HDBaseT that the professionals have become accustomed to.
HDBaseTHomePlay defines the adaptations across all seven layers of the Generic communication OSI 7 model to allow the support of time-sensitive, high throughput video/audio and other time sensitive applications.
While HDBaseT 1.0 addresses the Physical and Data Link layers only, HDBaseT 2.0 adds networking, switching and control point capabilities. HDBaseT 1.0 defined a point-to-point connectivity standard,HDBaseT 2.0 defines point-to-multi point connectivity, thereby providing multi-stream support.
Spec 2.0 also adds inherent support for USB 2.0, and other native interfaces which enable manufacturers to remove multiple interfaces and conversion components required for HDBaseT 1.0 products. The result is a smaller and a simpler-to- implement switch.
HDBaseT 1.0 was defined to support the transmission of “video, audio, Ethernet, power and controls, what we refer to as the “5Play” feature set. Spec 2.0 establishes a specification that will allow HDBaseTHomePlay switches to control and distribute multimedia throughout consumers’ homes.
HDBaseT 2.0 represents the culmination of more than two years of development work by both Pro-AV and CE manufacturers, and it offers significant benefits to the pro-AV companies such as native USB2.0 and additional features to improve performance margin including for 4K video and optimize the existing infrastructure and bandwidth.
