Why are HDMI 1.3 products better than prior versions of HDMI
Q. What is the difference between HDMI 1.3, HDMI 1.3a and 1.3b? For consumers, there is no difference between HDMI version 1.3 and 1.3a or 1.3b. These minor revisions to the specification typically relate to manufacturing or testing issues and do not impact features or functionality. In addition, we at HDTV Supply are actively working with manufacturers to reduce confusion for consumers by de-emphasizing version numbers and focusing instead on product features and functionality.
The latest version of HDMI 1.3 is up to 1.3b, but there are four main versions that most equipment will correspond to -- 1.0, 1.1, 1.2 and 1.3. Notice that the versions correspond with the types of audio they can transmit, as all versions should be able to transmit HD video up to 1080p.

HDMI 1.0: This is the first version of HDMI and it was ratified in late 2002. It will decode most versions of audio contained in DVD and digital TV signals, including Dolby Digital and DTS.
HDMI 1.1: This version added DVD-Audio support, which means users with compatible disks and players can listen to 5.1 channel audio streams without the need for six separate audio RCA cables.
1.2/1.2a: The main improvement on 1.1 is the addition of Super Audio CD (SACD) support, which means users no longer need to rely on iLink or analog cables to listen to SACDs. The standard also adds support for an as-yet unused Type A PC connector.
HDMI 1.3/1.3a/1.3b: Version 1.3 adds support for Dolby TrueHD and DTS-HD Master Audio which are used in Blu-ray and HD DVD players. As yet, the only device on the market that supports this standard is the PlayStation 3, but in the coming months most manufacturers plan to release compatible surround receivers. The standard also increases the bandwidth by a factor of two to 10Gbps.
Question: Will HDMI 1.3 products work with my non-1.3 devices?
Answer: Yes, all versions of HDMI are backward and forward compatible. They will all work but non-1.3 products will not support extended bandwidth features of 1.3 devices like "Deep Color." An HDMI 1.3 Category 1 device can carry a signal with a pixel clock of 74.25 MHz whereas an HDMI 1.3 Category 2 device can carry a signal with a pixel clock greater than 74.25 MHz.
These HDMI 1.3 products are fully compatible with all prior versions of HDMI and will support all the new feature including DEEP COLOR (high color bit depth) and enhanced multi-channel digital audio formats (Dolby TrueHD, DTS-HD Master Audio).
