HDMI Licensing has announced the release of HDMI Specification Version 1.4a featuring some enhancements for 3D applications including the addition of mandatory 3D formats for broadcast content as well as the addition of the 3D format referred to as Top-and-Bottom. An extraction of the 3D portion of Specification Version 1.4a is also freely available for public download on the HDMI Web site in order to provide public access to the 3D portion of the HDMI Specification for those companies and organizations that are not HDMI Adopters, but require access to this portion of the Specification.
Having set a complete set of Mandatory 3D Formats in HDMI Specification Version 1.4 (with the updates available in 1.4a), the association is trying to ensure interoperability for devices designed to deliver 3D content over the HDMI connection. Implementing the mandatory formats of the HDMI Specification facilitates interoperability among devices, allowing devices to speak a common 3D language when transmitting and receiving 3D content. Or in plain words that means that you’ll be able to plug in your PlayStation 3 console, when it is updated to support stereo 3D, into a 3D-ready Samsung HDTV for example and not only having to use it with a compatible Sony TV set. Here is a list of the mandatory 3D formats that should all be supported by all compatible displays to ensure full compatibility…
For movie content (like Blu-ray 3D)
– Frame Packing: 1080p @23.98/24Hz
For game content (like PS3)
– Frame Packing: 720p @50 or 59.94/60Hz
For broadcast content (like 3D TV)
– Side-by-Side Horizontal: 1080i @50 or 59.94/60Hz
– Top-and-Bottom: 720p @ 50 or 59.94/60Hz or 1080p @23.97/24Hz
