{{Short description|Technology for connecting consumer electronics}}
'''LiquidHD''' technology was an architecture and a set of protocols for networking [consumer electronics](/source/consumer_electronics) devices. It was designed to let consumers link their HDTVs, home theater components, PCs, gaming consoles, and mobile devices into local entertainment networks, where they could view [high-definition](/source/High-definition_television) digital content from any networked source device on any compliant display.
[Silicon Image](/source/Silicon_Image) promoted LiquidHD in 2009 and sponsored a website for it that year.[{{Cite web |title= LiquidHd - Digital Entertainment Unleashed |work= Promotional website |url= http://liquidhd.com/ |url-status=dead |archivedate=January 25, 2009 |archiveurl= https://web.archive.org/web/20090125151208/http://liquidhd.com/ |accessdate= December 1, 2013 }}]
==Description==
The LiquidHD architecture allowed network connections to be made via [Ethernet](/source/Ethernet), [coaxial cable](/source/coaxial_cable) (i.e., [MoCA](/source/Multimedia_over_Coax_Alliance) or [G.hn](/source/G.hn)[{{Cite news |title= New standard for home entertainment networks |date= January 8, 2009 |work= Financial Times |author= Chris Nuttall |url= http://www.ft.com/intl/cms/s/2/5a40d558-dd93-11dd-930e-000077b07658.html |accessdate= December 1, 2013 }}]), [802.11](/source/802.11) wireless, [powerline communication](/source/powerline_communication) (such as G.hn or other specifications such as [HomePlug](/source/HomePlug), [HD-PLC](/source/HD-PLC) or [Universal Powerline Association](/source/Universal_Powerline_Association)), phone lines ([HomePNA](/source/HomePNA) or G.hn) or [HDMI](/source/HDMI), depending on the usage scenario and what connections were already available. Once devices were linked in a LiquidHD network, users could control them via a remote user interface, enabling sharing of source devices and facilitating activities such as pausing a program in one room and resuming it in another.
LiquidHD included protocols for:[{{Cite web |title= LiquidHD Digital Entertainment Unleashed |work= Promotional brochure |date= January 22, 2009 |url= http://cn.siliconimage.com/docs/LiquidHD_Technology_Overview.pdf |accessdate= December 1, 2013 }}]
* Automatic discovery and authentication of LiquidHD-enabled devices
* High-definition media streaming from live and stored sources across the network
* Remote access of any source device's user interface to any LiquidHD display device, and for a single remote control at each display to control all source devices on a network.
* Secure communication between connected devices
* Security and content protection, including [digital rights management](/source/digital_rights_management) for consumers to play their legally-obtained content on any LiquidHD display, and protect the network from hostile attacks
Development began in the summer of 2007.
It was announced January 8, 2009 at the [Consumer Electronics Show](/source/Consumer_Electronics_Show) in [Las Vegas](/source/Las_Vegas).[{{Cite news |title= Silicon Image Unveils LiquidHD |author= Wendy Sheehan Donnell |date= January 8, 2009 |work= PC Magazine |url= https://www.pcmag.com/article2/0,2817,2338367,00.asp |accessdate= December 1, 2013 }}]
By September 2009 analysts observed that no major customers had adopted the technology.[{{Cite news |title= Will Silicon Image's LiquidHD gamble pay off? |work= EE Times |date= August 14, 2009 |author= Junko Yoshida |url= http://www.eetimes.com/document.asp?doc_id=1263554 |accessdate= December 1, 2013 }}]
After announcing declining sales in the [Great Recession](/source/Great_Recession), the company replaced its chief executive in September 2009 as it was criticized for spreading itself over too many new initiatives.[{{Cite news |title= Analysis: Behind the downfall of Silicon Image's CEO |work= EE Times |date= September 30, 2009 |author= Bolaji Ojo |url= http://www.eetimes.com/document.asp?doc_id=1171826 |accessdate= December 1, 2013 }}]
Silicon Image mentioned the technology on its web site in 2010, but quietly dropped it in early 2011 under new chief executive Camillo Martino.[{{Cite web |title= LiquidHD™ Technology |publisher= Silicon Image |work= Company website |url= http://www.siliconimage.com/technologies/index.aspx?Page=13&Section=1 |url-status=dead |archiveurl= https://web.archive.org/web/20100923112429/http://www.siliconimage.com/technologies/index.aspx?Page=13&Section=1 |archivedate= September 23, 2010 |accessdate= December 1, 2013 }}][{{Cite news |title= Silicon Image pushes 'connectivity co-processor' for TV |work= EE Times |date= January 24, 2011 |author= Junko Yoshida |url=http://www.eetimes.com/document.asp?doc_id=1258444 |accessdate= December 1, 2013 }}]
