HDMI: New Definition
The HDMI format definition has evolved, and a new version 1.3 is available.
Among the new features, the bandwidth will increase by rising up the frequency from 165 to 215MHz, and colors will be 36-bits coded instead of 30-bits previously.
Concerning the audio, the new version will support the future Dolby HD and DTS HD contents.
Do not forget that you will need a HDMI-enable display/TV to be able to watch protected HD contents on it. But the current HDMI version 1.2a installed in all devices will be sufficient to manage all HD movies that should appear in a near future.
