No signal conversion is necessary, nor is there a loss of video quality when a DVI-to-HDMI adapter is used. [5]: §C The Consumer Electronics Control (CEC) capability allows HDMI devices to control each other when necessary and allows the user to operate multiple devices with one handheld remote control device. [5]: §6.3
It can also carry audio, USB, and other forms of data. DisplayPort is backward compatible with other interfaces such as HDMI and DVI through the use of active or passive adapters. Male Mini DisplayPort plug Mini DisplayPort: Proposed alternative to HDMI, used with computer displays: (VGA, DVI) Apple Inc.'s successor to their own Mini-DVI.
Consumer Electronics Control (CEC) is a feature of HDMI designed to control HDMI connected devices [1] [2] by using only one remote controller; so, individual CEC enabled devices can command and control each other without user intervention, for up to 15 devices.
Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
Schematic of a TMDS link used as a link for digital component video data (RGB) between a video controller (PC) and a display controller (Monitor) in interfaces such as DVI or HDMI Transition-minimized differential signaling ( TMDS ) is a technology for transmitting high-speed serial data used by the DVI [ 1 ] and HDMI video interfaces, as well ...
HDMI lacks VGA compatibility and does not include analog signals. DVI is limited to the RGB color model while HDMI also supports YCbCr 4:4:4 and YCbCr 4:2:2 color spaces, which are generally not used for computer graphics. In addition to digital video, HDMI supports the transport of packets used for digital audio.
It defines a new license-free, royalty-free, digital audio/video interconnect, intended to be used primarily between a computer and its display monitor, or a computer and a home-theater system. The video signal is not compatible with DVI or HDMI , but a DisplayPort connector can pass these signals through.
A sink has one or more HDCP/HDMI receivers. [4] Repeater A repeater accepts content, decrypts it, then re-encrypts and retransmits the data. It may perform some signal processing, such as upconverting video into a higher-resolution format, or splitting out the audio portion of the signal. Repeaters have HDMI inputs and outputs.
