Standard HDMI (High Definition Multimedia Interface) – an interface for transmitting data between devices. Since 2002, when this interface was introduced, there have been a few different standards.
Description and specification:
HDMI 1.0 (introduction date: the end of 2002 ) – audio-video transmission with the throughput of 4.9 Gb/s – supporting the resolution of 1080p at 60 Hz – 8 audio channels with the sampling frequency of 192 kHz – 8-bit colour depth
HDMI 1.1 (May 2004) – supporting DVD Audio – small mechanical and electrical changes – first mass-selling cable version
HDMI 1.2 (August 2005) – supporting transmission Super Audio CD (a rare standard of a sound carrier created by Sony and Philips) – A type pin for computers – higher colour depth for computers (RGB + YCbCr) – these cables also work with low voltage and they can be found on current video card interfaces
HDMI 1.2a (the end of 2005) – the only cable version with complete documentation and standardisation CEC (Consumer Electronic Control)
HDMI 1.3 (June 2006) The former versions did not differ too much but here a real revolution starts: – increased transmission rate to 10.4 Gb/s as part of the demand for future devices with higher resolution – considerably higher colour depth – this standard currently supports 10, 12 and 16 bits (compared to the previous versions) – support for the function of "x.v.Color" – enabling the display of every colour which can be seen with the human eye – audio and video synchronisation (AV Sync) and Dolby True HD and DTS-HD – C "mini" type pins were created for handling video cameras.
HDMI 1.3 a-c (November 2006 – November 2007) These were only corrective and test versions for new devices: – a command list was added to CEC – small modifications in the C type pin
HDMI 1.4 (May 2009) Another revolutionary cable version: – supporting ethernet channel in HDMI devices – introduction of audio return channel (no need for a separate audio cable) – supporting 3D technology – supporting 2K and 4K resolution – introducing micro type pin for telephones and other mobile devices
HDMI 1.4 a-b (March 2010 – October 2011) – small improvements, mainly with 3D technology supporting
HDMI 2.0 (September 2013) Version created for the most demanding users: – increasing the transmission rate (now it is 18 Gb/s) – handling up to 32 audio channels – handling full resolution 4K at 60 Hz – colour depth from 24 to 48 bits – supports image format of 21:9 – dynamic audio and videos synchronisation
