Upper Saddle River, N.J. - Onkyo is offering HDMI 1.4a inputs and outputs in previously announced A/V receivers and home theater in a box (HTiB) systems to support 3D broadcast content, the company said.

Last month, the company unveiled its first three A/V receivers and first three home-theater receiver/speaker packages with 3D-capable HDMI 1.4 inputs and outputs. Now the company is saying the six products are actually shipping with HDMI 1.4a, which adds support for the Side-By-Side (Half) and Top-and-Bottom 3D formats that broadcasters are adopting. Like before, the devices are compatible with current 3D Blu-ray content.

The previously announced products also support HDMI 1.4's audio return channel (ARC).

All other AVRs and HTiBs that Onkyo will roll out this year will also feature HDMI 1.4a, the company added.

 he previously announced AVRs are the $299-suggested 5.1-channel TX-SR308, $399 7.1-channel TX-SR508, and $599 7.2-channel TX-SR608. The receiver/speaker packages are the $379-suggested 5.1-speaker HT-S3300, $599 7.1-speaker HT-S5300, and $349 HTX-22HDX, which is a 2.1-speaker HTiB with virtual surround processing.
