HDMI implements the EIA/CEA-861 standard, which defines video formats and waveforms, transport of compressed and uncompressed LPCM audio, supplementary data, and implementation of VESA EDID. III CEA-861 signals carried by HDMI are electrically compatible with CEA-861 signals used by Digital Visual Interface (DVI). No signal conversion is required, nor is there any loss of video quality when a DVI-to-HDMI adapter is used. :§C Consumer Electronics Control (CEC) capability allows HDMI devices to control each other when necessary and allows users to operate multiple devices with one handheld remote control device. : 6.3
Several versions of HDMI have been developed and used since the technology’s initial release, but all use the same cables and connectors. In addition to increased audio and video capacity, performance, resolution, and color space, the newer version includes optional advanced features such as 3D, Ethernet data connection, and CEC extensions.
Production of consumer HDMI products began in late 2003. In Europe, either DVI-HDCP or HDMI are included in the HD ready labeling specification for TV sets for HDTVs, formulated by EICTA with SES Astra in 2005. HDMI began appearing on consumer HDTVs in 2005. 2004 and camcorders and digital still cameras in 2006. By January 2021, nearly 10 billion HDMI devices had been sold.
That’s a brief understanding of the HDMI port from me, hopefully this article can help those of you who are looking for information about the HDMI port. That’s all from me, sorry if there are any wrong words from me as the author of this article and thank you for taking the time to visit the articles I made and for visiting our my method website.
