No signal conversion is necessary, nor is there a loss of video quality when a DVI-to-HDMI adapter is used. HDMI devices to control each other when necessary and allows the user to operate multiple devices with one handheld remote control device. Several versions of HDMI have been developed and deployed since initial release of the technology, but all use the same cable and connector. Production of consumer HDMI products started in late 2003. The HDMI founders were Hitachi, Panasonic, Philips, Silicon Image, Sony, Thomson, RCA, and Toshiba.
The HDMI founders began development on HDMI 1. 0 on April 16, 2002, with the goal of creating an AV connector that was backward-compatible with DVI. HDMI products, was opened by Silicon Image on June 23, 2003, in California, United States. The first ATC in Japan was opened by Panasonic on May 1, 2004, in Osaka. According to In-Stat, the number of HDMI devices sold was 5 million in 2004, 17. 4 million in 2005, 63 million in 2006, and 143 million in 2007. On January 28, 2008, In-Stat reported that shipments of HDMI were expected to exceed those of DVI in 2008, driven primarily by the consumer electronics market.
In 2008, PC Magazine awarded a Technical Excellence Award in the Home Theater category for an “innovation that has changed the world” to the CEC portion of the HDMI specification. On October 25, 2011, the HDMI Forum was established by the HDMI founders to create an open organization so that interested companies can participate in the development of the HDMI specification. On January 8, 2013, HDMI Licensing, LLC announced that there were over 1,300 HDMI adopters and that over 3 billion HDMI devices had shipped since the launch of the HDMI standard. The HDMI specification defines the protocols, signals, electrical interfaces and mechanical requirements of the standard. The maximum pixel clock rate for HDMI 1.
3 uses the CEA-861-D video standard, and HDMI 1. 4 uses the CEA-861-E video standard. HDMI devices must implement the sRGB color space at 8 bits per component. 3, HDMI allows lossless compressed audio streams Dolby TrueHD and DTS-HD Master Audio. CBCR video, audio capability is optional. Return” refers to the case where the audio comes from the TV and can be sent “upstream” to the AV receiver using the HDMI cable connected to the AV receiver.

HDMI has three physically separate communication channels, which are the DDC, TMDS and the optional CEC. HDMI interleaves video, audio and auxiliary data using three different packet types, called the Video Data Period, the Data Island Period and the Control Period. During the Video Data Period, the pixels of an active video line are transmitted. 10b encoding for the Control Period. 10b encoding for the Data Island Period. It is a one-wire bidirectional serial bus that is based on the CENELEC standard AV. It was defined in HDMI Specification 1.
0 and updated in HDMI 1. USB to CEC adapters exist that allow a computer to control CEC-enabled devices. HEC is transmitted as a differential signal over the pair of lines, and ARC as a common mode component of the pair. This direction is used when the TV is the one that generates or receives the video stream instead of the other equipment.
An adapter with a DVI receptacle connector to HDMI plug connector. An adapter with an HDMI receptacle connector to DVI plug connector with a close up of the HDMI connector. No signal conversion is required when an adapter or asymmetric cable is used, so there is no loss of video quality. From a user’s perspective, an HDMI display can be driven by a single-link DVI-D source, since HDMI and DVI-D define an overlapping minimum set of allowed resolutions and framebuffer formats to ensure a basic level of interoperability. Typically, the only limitation is the gender of the adapter’s connectors and the gender of the cables and sockets it is used with. Features specific to HDMI, such as remote-control and audio transport, are not available in devices that use legacy DVI-D signalling.
Exact capabilities beyond basic compatibility vary. Intel created the original technology to make sure that digital content followed the guidelines set by the Digital Content Protection group. HDMI can use HDCP to encrypt the signal if required by the source device. HDCP accommodates up to 127 connected devices with up to 7 levels, using a combination of sources, sinks and repeaters.
Devices called HDCP strippers can remove the HDCP information from the video signal so the video can play on non-HDCP-compliant displays, though a fair use and non-disclosure form must usually be signed with a registering agency before use. A close up image of the end three HDMI plugs: Type D, Type C and Type A. There are five HDMI connector types. B are defined in the HDMI 1. 0 specification, type C is defined in the HDMI 1. E are defined in the HDMI 1. There are 19 pins, with bandwidth to carry all SDTV, EDTV, HDTV, UHD, and 4K modes.
It is electrically compatible with single-link DVI-D. Type B This connector is 21. It is electrically compatible with dual-link DVI-D, but has not yet been used in any products. Type C This Mini connector is smaller than the type A plug, measuring 10. 42 mm but has the same 19-pin configuration. It is intended for portable devices. CEC Ground is assigned to pin 13 instead of pin 17, the CEC is assigned to pin 14 instead of pin 13, and the reserved pin is 17 instead of pin 14.
