In a written statement released last week, Onkyo has confirmed that its new 3D-Ready home theater receivers and home theater in a box (HTiB) systems which began shipping in March will support the new HDMI v1.4a connectivity standard.

HDMI Licensing, LLC, the group responsible for overseeing the HDMI standard, had introduced the new HDMI v1.4a standards last month after Onkyo had begun shipping its new systems which led to confusion among potential buyers concerned about 3D playback.

The new HDMI V1.4a standard was a surprise to consumers since it came less than nine months after the v1.4 standard was introduced. The HDMI v1.4a specification added two more mandatory 3D formats called "Side-by-Side Horizontal' and "Top-and-Bottom."

The industry trade group defended the updated specification, which will render some home theatre equipment still on retail shelves obsolete, by saying it was necessary so home theatre devices could "speak a common 3D language when transmitting and receiving 3D content."

For consumers who want to guarantee their home theatre systems are 3DTV compatible, it means that your home theatre equipment must be HDMI v1.4a compatible.


In an attempt to alleviate consumer concerns about its products ability to support 3DTV, Onkyo issued a special written statement last week saying that all the following equipment is HDMI v1.4a compatible even though it is not specifically stated on their products.
