Personal computer (PCs) with a DVI interface are capable of video output to an HDMI-enabled monitor. [5]: appx. C Some PCs include an HDMI interface and may also be capable of HDMI audio output, depending on specific hardware. [161]
The EIA/CEA-861-C and -D standards have the first 59 short video descriptors above. EIA/CEA-861-D is used by HDMI 1.3–1.3c. The EIA/CEA-861-E standard has the first 64 short video descriptors above. It is used by HDMI 1.4–1.4b. The CTA-861-F standard has the first 107 short video descriptors above. It is used by HDMI 2.0–2.0b.
A video decoder is an electronic circuit, often contained within a single integrated circuit chip, that converts base-band analog video signals to digital video. [1] Video decoders commonly allow programmable control over video characteristics such as hue , contrast , and saturation .
It is possible to have a decoder which only supports decoding a subset of profiles and levels of a given video format, for example to make the decoder program/hardware smaller, simpler, or faster. [53] A profile restricts which encoding techniques are allowed. For example, the H.264 format includes the profiles baseline, main and high (and others).
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.
On April 3, 2013, ATEME announced the availability of the first open source implementation of a HEVC software player based on the OpenHEVC decoder and GPAC video player which are both licensed under LGPL. [30] [31] The OpenHEVC decoder supports the Main profile of HEVC and can decode 1080p at 30 fps video using a single core CPU.
Decode sound in MP2, PCM or AC-3 format and output (with optional AC-3 to stereo downmixing) on stereo connector, optical or electric digital connector; Output a video signal, either an analog one (in NTSC or PAL format) on the composite, S-Video, SCART, or component video connectors, or a digital one on the DVI or HDMI connectors.
Earlier versions of HDMI, such as HDMI 1.1, support PCM audio, where the player decodes the audio and transmits it losslessly as PCM over HDMI to the receiver. Some receivers and players support analog surround sound, and the player can decode the audio, and transmit it to the receiver as analog audio. Most receivers and players support S/PDIF.
