Better Sound with an HDMI Cable Connection
HDMI cables have been updated several times through its nine-year long existence. Originally, the basics were supported, such as standard RGB and YCbCr, 8 channel LPCM, 192 kHz, 24 bit audio capabilities, blu-ray and HD DVD at full resolution and Consumer Electronic Control. There are four main version upgrades with minor fixes inserted in. Version 1.1 provided DVD-Audio support. This form of audio is similar to the Super Audio CD, a method of delivering audio content at much higher qualities than traditional CDs. Version 1.2 and 1.2a added in Super Audio CD support. Version 1.3 was the biggest update and provided Deep Color (more than 16.7 million colors), xvYCC (Extended color gamut), auto lip-sync, Dolby TrueHD and DTS-HD Master Audio. The minor update to 1.3 added in an updated Consumer Electronic Control command list. Version 1.4 allows for use of the ethernet, audio return, 4k x 2k resolutions and 3D video. A minor update to 1.4 allowed for 3D at a higher quality.
