HDMI 1.3 has been the talk of the forums lately. Everyone wants to know what's going on with the new spec and what it means to the current and future crop of AV devices. We were fortunate enough to be able to do a brief Question and Answer exchange with Leslie Chard, President of HDMI Licensing, LLC to get a better idea of the recent changes to the HDMI spec. In particular we were interested in both the audio and video differences found in HDMI 1.3. Here is the result of our Q&A session.
What specifically does HDMI 1.3 add to the 1.2a spec in terms of audio Video format support?
HDMI 1.3 can support new formats and capabilities in both audio and video areas. HDMI 1.3 increases its single-link bandwidth from 165MHz (4.95 gigabits per second) to 340 MHz (10.2 Gbps).
With this increased bandwidth capability, HDMI 1.3 supports the demands of future high definition display devices, such as higher resolutions, high frame rates and Deep Color. Let’s look at each of these specifically to see what it means to end users.

- Higher resolution – HDMI 1.3 can provide over 450% the resolution of 720p HDTV, and over 225% of 1080p HDTV for greater detail and larger display sizes.
