What are the differences between HDMI v.1.2 and 1.3?
HDMI 1.3 has all of the features of 1.2 plus; Deep Color: Deep Color lets HDTVs and other displays go from millions of colors to billions of colors allowing consumers to enjoy unprecedented vividness and accuracy of color on their displays. Deep Color eliminates on-screen color banding, for smooth tonal transitions and subtle gradations between colors. It enables increased contrast ratio, and can represent many times more shades of gray between black and white. Lip Sync: In a DTV, typically the video processing takes more time than the audio. As a result, lip sync can become an issue where it’s noticeable to the viewer, creating an effect similar to that of a badlydubbed movie. HDMI 1.3 provides a method whereby the audio processing times in devices can be automatically adjusted to remove lip sync. Lossless Audio Formats HDMI 1.3 adds additional support for new, lossless compressed digital audio formats Dolby TrueHD and DTS-HD Master Audio for theater-like, professional sound quality.
