Valens HDBaseT™ technology empowers plug-and-play digital connectivity between HD video sources and remote displays. 5Play feature set, converged through a single 100m/328ft CAT5e/6 cable enables the delivery of:
Video – Uncompressed high-definition /3D video in up to 4K resolution
Audio – Any standard digital audio format
Ethernet – 100BaseT Ethernet
Control – Various control signals including CEC, RS-232, USB and IR
Power – Up to 100W using Power-over-Cable
HDBaseT™ delivers Full HD/3D and 2K/4K uncompressed video to a network of devices, or as a point-to-point connection. Video transmission is based on a pass-through from an HDMI chipset, thus supporting all key features of HDMI 1.4, including EPG, CEC, EDID, HDCP and more. Valens proprietary video coding scheme ensures the highest video quality with zero latency.
As in for video, HDBaseT™ Audio is passed-through directly from the HDMI chipset, thus supporting all standard formats, such as Dolby Digital, DTS, Dolby TrueHD, DTS HD-Master Audio and more.
HDBaseT™ supports 100Mb Ethernet capabilities, enabling televisions, hi‐fi equipment, computers, and other CE devices to communicate with each other and access stored multimedia content, including video streaming, pictures and music. Relying on the same physical infrastructure, HDBaseT™ also supports Ethernet Fallback Mode. This means you can plug an HDBaseT device into an Ethernet‐only infrastructure, and the device will seamlessly "realize" it, and will only enable the Ethernet capabilities of the connection.
HDBaseT™ delivers different types of control signals for different purposes, from Consumer Electronic Controls (CEC) to Recommended Standard (RS)-232, USB and infrared (IR). Since HDBaseT™ also caters for an Ethernet channel, IP control can also be used. This opens endless possiblities for equipment manufacturers, from remote control over distant devices to complete managed network capabilities.
As part of its 5Play™ feature-set, HDBaseT™ supports transmission of up to 100W of DC power over the same CAT5e/6 cable. This significant feature provides the ultimate possiblity to forego plugging devices into the wall outlet for power, allowing greater mobility.
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 tehcnology 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 benfits of the cost-effective CAT infrastrcture.
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 HDBaseT HomePlay 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.
HDBaseT HomePlay 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.
Unlike other HD distribution technologies currently available, HDBaseT is the only technology that enables long-reach wired connectivity up to 100 meters for uncompressed ultra-HD multimedia content and up to 100 watts of charging 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. Other existing solutions also require a specific cable and/or a new proprietary connector while HDBaseT utilizes the existing Ethernet infrastructure.
Yes. HDBaseT is the only standard that delivers uncompressed Ultra-HD 4K video for up to 100m
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.
HDBaseT enables full ultra-HD/3D and 2K/4K uncompressed video, and is compatible with all HDMI formats. It provides the highest video quality, with zero latency, and directly relays digital audio from the HDMI chipset. It supports all audio standard formats, including TrueHD,DTS HD-Master Audio, Dolby Pro Logic Iiz 7.1 & 9.1, and more.
HDBaseT technology is optimized for the delivery of uncompressed, ultra-high-definition digital media, and can connect all the entertainment devices in the home through its "5Play" feature set, converging uncompressed ultra HD digital video/audio, 100BaseT Ethernet, USB 2.0, up to 100W of Power (through Power over HDBaseT POH) and various control signals all through a single 100m/328ft Cat6 cable.
No. Audio Return Channel -enabled devices can be connected via all the existing categories of HDMI cables.
Yes. Whether the TV is sending audio to the sound system or vice-versa, devices featuring LipSync functionality (introduced in HDMI 1.3) will be able to track and correct for any processor lags, and adjust the delivery of audio and video so that the two signals stay in sync.
The Audio Return Channel supports all the same audio formats that can be sent through a traditional S/PDIF audio connection, including Dolby Digital, DTS, and PCM audio.
If your HDTV has a built-in tuner, DVD player, or other digital content source, the Audio Return Channel allows the TV to send audio data “upstream” to your A/V receiver, eliminating the need for a separate audio cable in this type of configuration. Audio Return Channel-enabled TVs can either send or receive audio via the HDMI link, giving you greater flexibility in how you set up your home theater equipment and making a separate upstream audio link unnecessary.
Probably not. Most of the new features introduced in HDMI 1.4 will require a new HDMI chip to enable, and cannot be upgraded via firmware.
The HDMI Ethernet Channel enables a number of new possibilities via the HDMI link, including:
Sharing an internet connection – The HDMI Ethernet Channel feature allows your internet-ready entertainment devices, from gaming consoles to Blu-ray Disc players and more, to share an internet connection without any need for a separate Ethernet cable.
Content distribution – Devices connected by the HDMI Ethernet Channel will be able to exchange digital content in its native format, enabling recording, storage, and playback options across a connected system, with no need for a separate Ethernet cable.
Home entertainment networking – The HDMI Ethernet Channel accommodates current and future IP-based networking solutions for consumer electronics, such as UPnP, LiquidHD, and DLNA. HDMI with Ethernet is the ideal one-cable solution for connecting devices in these advanced home-networking environments.
The HDMI Ethernet Channel feature supports any networking protocol that can run over an existing Ethernet connection, including TCP/IP, UPnP, DLNA, LiquidHD, and so forth.
Yes, devices built to the HDMI 1.4 specification will be fully backwards-compatible with existing HDMI devices and their features.
Recently, HDMI Licensing, LLC announced that cables would be tested as Standard or High-Speed cables.
Standard (or “category 1”) HDMI cables have been tested to perform at speeds of 75Mhz or up to 2.25Gbps, which is the equivalent of a 720p/1080i signal.
High Speed (or “category 2”) HDMI cables have been tested to perform at speeds of 340Mhz or up to 10.2Gbps, which is the highest bandwidth currently available over an HDMI cable and can successfully handle 1080p signals including those at increased color depths and/or increased refresh rates from the Source. High-Speed cables are also able to accommodate higher resolution displays, such as WQXGA cinema monitors (resolution of 2560 x 1600).
