No signal conversion is necessary, nor is there a loss of video quality when a DVI- to- HDMI adapter is used. Other than improved audio and video capacity, performance, resolution and color spaces, newer versions have optional advanced features such as 3.

High-Definition Multimedia Interface (HDMI) is an audio/video interface for transmitting digital data which provides better quality output than analog.

Audio return channel (ARC) is a feature introduced in the HDMI 1. This limits the caption style (even for digital captions) to only that decoded at the source prior to HDMI transmission. This also prevents closed captions when transmission over HDMI is required for upconversion. For example, a DVD player that sends an upscaled 7. HDMI to an HDTV has no way to pass Closed Captioning data so that the HDTV can decode it, as there is no line 2. VBI in that format. Communication channels. HDMI specifically requires the device implement the Enhanced Display Data Channel (E- DDC), which is used by the HDMI source device to read the E- EDID data from the HDMI sink device to learn what audio/video formats it can take. During the Video Data Period, the pixels of an active video line are transmitted. During the Data Island period (which occurs during the horizontal and vertical blanking intervals), audio and auxiliary data are transmitted within a series of packets. The Control Period occurs between Video and Data Island periods. HDMI adds the ability to send audio and auxiliary data using 4b/1. Data Island Period. Each Data Island Period is 3. Packet Header, which includes 8 bits of BCH ECC parity data for error correction and describes the contents of the packet. Each packet contains four subpackets, and each subpacket is 6. BCH ECC parity data, allowing for each packet to carry up to 2. Each Data Island Period can contain up to 1. Seven of the 1. 5 packet types described in the HDMI 1. Among these are the General Control Packet and the Gamut Metadata Packet. The General Control Packet carries information on AVMUTE (which mutes the audio during changes that may cause audio noise) and Color Depth (which sends the bit depth of the current video stream and is required for deep color). The Gamut Metadata Packet carries information on the color space being used for the current video stream and is required for xv. YCC. CEC also allows for individual CEC- enabled devices to command and control each other without user intervention. HEAC utilizes two lines from the connector: the previously unused Reserved pin (called HEAC+) and the Hot Plug Detect pin (called HEAC. No signal conversion is required when an adapter or asymmetric cable is used, so there is no loss of video quality. C)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. In the reverse case a DVI- D monitor would have the same level of basic interoperability unless there are content protection issues with High- bandwidth Digital Content Protection (HDCP) or the HDMI color encoding is in component color space YCb. Cr which is not possible in DVI, instead of RGB. An HDMI source such as a Blu- ray player may demand HDCP- compliance of the display, and refuse to output HDCP- protected content to a non- compliant display. 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. However, many devices output HDMI over a DVI connector (e. ATI 3. 00. 0- series and NVIDIA GTX 2. Exact capabilities beyond basic compatibility vary from product to product. Adapters are generally bi- directional. Content protection (HDCP). 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. CSS, CPRM and AACS require the use of HDCP on HDMI when playing back encrypted DVD Video, DVD Audio, HD DVD and Blu- ray Disc. The HDCP Repeater bit controls the authentication and switching/distribution of an HDMI signal. According to HDCP Specification 1. HDMI CTS 1. 3a), any system that implements HDCP must do so in a fully compliant manner. HDCP testing that was previously only a requirement for optional tests such as the . Type A/B are defined in the HDMI 1. C is defined in the HDMI 1. D/E are defined in the HDMI 1. Type AThe plug (male) connector outside dimensions are 1. It is electrically compatible with dual- link DVI- D, but has not yet been used in any products. As of HDMI 1. 4, the pixel clock rate crossover frequency from single to dual- link has not been defined. For comparison, a micro- USB connector is 6. It keeps the standard 1. A and C, but the pin assignment is different from both. A relay connector is available for connecting standard consumer cables to the automotive type. This cable will connect to video display/sink devices using any of the native HDMI connectors. This is an HDMI cable, in this case a USB Type- C to HDMI cable. HDMI cables with Ethernet differ in that three of the separate conductors instead form an additional shielded twisted pair (with the CEC/DDC ground as a shield). In addition to expanding the set of cable testing requirements, the certification program introduces an EMI test to ensure cables minimize interference with wireless signals. These cables are marked with an anti- counterfeiting authentication label and are defined as. HDRPremium High Speed HDMI Cable with Ethernet. In conjunction with the HDMI 2. January 4, 2. 01. HDCP DDC signals must be multiplexed with TMDS video signals to be compliant with HDCP requirements for HDMI extenders based on a single Category 5/Category 6 cable. Active HDMI cables use electronics within the cable to boost the signal and allow for HDMI cables of up to 3. III) Each subsequent version of the specification uses the same kind of cable but increases the bandwidth or capabilities of what can be transmitted over the cable. III) A product listed as having an HDMI version does not necessarily mean that it will have all of the features that are listed for that version. It defines up to 3. Gbit/s of video bandwidth (1. Hz or UXGA) and 8 channel LPCM/1. Hz/2. 4- bit audio. III)Version 1. 1. III)Version 1. 2. It also added the availability of HDMI type A connectors for PC sources, the ability for PC sources to implement only the s. RGB color space while retaining the option to implement the YCb. Cr color space, and required HDMI 1. III)Version 1. 3. It also optionally allows output of Dolby True. HD and DTS- HD Master Audio streams for external decoding by AV receivers. It also changed CEC capacitance limits, clarified s. RGB video quantization range, and CEC commands for timer control were brought back in an altered form, with audio control commands added. It also added the optional ability to stream SACD in its bitstream DST format rather than uncompressed raw DSD like from HDMI 1. III)HDMI 1. 3b, 1. March 2. 6, 2. 00. November 9, 2. 00. August 2. 5, 2. 00. They do not introduce differences on HDMI features, functions, or performance. HDMI 1. 4 requires that 3. D displays implement the frame packing 3. D format at either 7.
