The inevitable rule in the information age is: "if it can be digitized, it will."
The transition from analog to digital in the video world has been quick and a key enabler of this has been HDMI, High Definition Multimedia Interface. Virtually all HD equipment utilizes HDMI to transport audio/video from the sources to the display. The original rendition of HDMI, HDMI 1.0 was released back in 2002 and has been the de facto standard for HD Video transmission.
HDMI enables full digital transport of both audio and video from source to display using a single cable. HDMI is the dominant standard for HD distribution and will continue to evolve in order to remain the best HD connection available. As the digital revolution has continued, HDMI has also evolved from 1.0, 1.1, 1.2 and mostly recently HDMI 1.3. Some of the key points regarding HDMI 1.3 are summarized below.
Do I need HDMI 1.3:
You will still get incredible 1080 P HD picture quality with HDMI 1.1 and HDMI 1.2. HDMI 1.3 is backwards compatible with previous versions of HDMI. Getting HDMI 1.3 display and HDMI sources will enable you to take advantage of the extra feature enhancements available. If you are in the market for a new HDTV, then it would be advisable to get one with HDMI 1.3 support. However, you should look for the specific features that are supported.
HDMI 1.3 - what is different:
On the physical layer level, all HDMI versions utilize Transmission Minimized Differential Signaling, TMDS and the physical connector looks identical. The major enhancements of HDMI 1.3 are:
Expanded Data Rate Support:
HDMI 1.2 supports aggregate data rate of 4.95 Gbps. In order to ensure that HDMI is the connectivity of the future, HDMI 1.3 has provisions to eventually double the bandwidth from 4.95 Gbps to 10.2 Gbps. For comparative purpose, USB 2.0 has a maximum data transfer rate of 480 Mbps, 1/20 of the data rate of HDMI 1.3.
Although, HDMI 1.3 has provision for up to 10.2Gbps, the transition will be gradual with the first devices available to achieve 6.75Gbps initially.
Deeper Color and higher resolution:
The increased bandwidth in HDMI 1.3 enables higher display resolutions beyond the typical 1920x1080P resolution and improved color depth. For example, HDMI 1.2 allows 8 bits/ pixel to be allocated for color information. In version 1.3, HDMI has provisions to support 10, 12 and 16 bit color/ pixel thus allowing for even improvement in picture quality.
Lip Synch Correction:
The modern HDTV performs complex digital processing to the incoming video signal such as de-interlacing, format conversion, noise reduction and etc. The digital video processing takes finite time to execute and must be synchronized with the audio portion of the incoming signal to ensure that both video and audio are synchronized and no delay is perceived. Most HDTV have compensation to ensure that the audio and video are properly synchronized However, many consumers will likely process the audio separately in a surround sound system. HDMI 1.3's lip synch feature allows the audio and video signal to be synchronized to external HDMI devices.
Mini Connector:
HDMI 1.3 has also added an optional mini HDMI connectors so handheld HD video devices such as HD video cameras can also utilize HDMI for HD connectivity.
What is still the same:
HDMI 1.3 is fully backwards compatible with previous versions of HDMI. So if your display supports 1.2 and your source is 1.3 capable. The source and display will arbitrate for the best available format. HDCP, although not required by HDMI 1.3, still enables HDCP to be implemented over the HDMI interface.
