Beginning with the seventh generation of video game consoles, most consoles support HDMI. In addition to the features in common with HDMI (such as HDCP encrypted uncompressed high-definition video and eight-channel surround sound), MHL also adds the provision of power charging for the mobile device while in use, and also enables the TV remote to control it. Quels sont les bénéfices du Dolby Digital Plus ? For example, displays with HDMI 1.4 ports do not necessarily support the full 340 MHz TMDS clock allowed by HDMI 1.4; they are commonly limited to lower speeds such as 300 MHz (1080p 120 Hz) or even as low as 165 MHz (1080p 60 Hz) at the manufacturer's discretion, but are still considered HDMI 1.4-compliant.

[41] "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. Others, such as the ASUS Eee Pad Transformer implement the standard using mini-HDMI (type C) ports. La technologie de compression très sophistiquée du DD+ permet d’obtenir un son de qualité proche du CD avec un débit de 128 kbits /sec. Ma question est la suivante : Products are not required to implement all features of a version to be considered compliant with that version, as most features are optional. Video Prime :PCM 3/2/0.1 Bonjour, All HDMI sources/sinks must also be capable of sending/receiving native Single-Link DVI video and be fully compliant with the DVI Specification.[95]. This, in combination with the 2.66x bandwidth, raises the maximum data rate of HDMI 2.1 from 14.4 Gbit/s to 42.66 Gbit/s, approximately 2.96x the data rate of HDMI 2.0. Video game consoles that support HDMI include the Xbox 360 (1.2a), Xbox One (1.4b), Xbox One S (2.0a), Xbox One X (2.0b), PlayStation 3 (1.3a), PlayStation 4 (1.4b), PlayStation 4 Pro (2.0a), Wii U (1.4a), Nintendo Switch (1.4b), Xbox Series X and Series S (2.1), and PlayStation 5 (2.1). Therefore, usable uncompressed video out of HDMI is often called "clean HDMI".

[22][32], 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. All future versions of the HDMI Specification were produced by the HDMI Forum, created on October 25, 2011. Et mon problème est que quand je regarde la tnt, ou n’importe quelle autre source, lors du changement d’une chaîne diffusant du stéréo et du Dolby digital +, mon ampli affiche » décoder off « . This enables HDMI 2.0 to carry 4K video at 60 Hz with 24 bit/px color depth. [70] Many HDMI cables under 5 meters of length that were made before the HDMI 1.3 specification can work as Category 2 cables, but only Category 2-tested cables are guaranteed to work for Category 2 purposes. HDMI 1.0 requires support for RGB video, with optional support for Y′CBCR 4:4:4 and 4:2:2 (mandatory if the device has support for Y′CBCR on other interfaces). Several versions of HDMI have been developed and deployed since the initial release of the technology, but all use the same cable and connector. Je souhaiterais donc passer sur un ampli dolby digital plus tout en restant en fibre optique + hdmi pour l’image. Pourquoi le DOLBY ATMOS sur les blu ray 4K n’est jamais ou très rarement disponible en Français? Difficile de s'y retrouver dans la jungle multicanal du Home-Cinema.
