Amplify the bandwidth of single-link mode to 340 Mhz (data transmission speed 10.2 Gbps)
Expanded support from 24bit color gamut (16.77 million colors) to 30-bit, 36-bit, and 48-bit (RGB or YCbCr) color gamut (equivalent to more than one billion color display)
Support the new xvYCC color standard
Support automatic voice synchronization (line to mouth) function

Propose a new miniaturized connector to support lightweight cameras
SonyPlayStation 3 is the first HDMI 1.3 player to be marketed.
Sony BRAVIA KDL-46X2500 and KDL-40X2500 are the first HDMI 1.3 displays on the market. (1080p supports the new xvYCC color standard, 36bits deep color)
