At this week's NAB show in Las Vegas, AJA Video Systems (http://www.aja.com) is previewing products-in-development featuring the Thunderbolt technology for new high-framerate 2K 3D, 4K and 5K workflows, and portable HD connectivity.

Thunderbolt technology is based HD/SD I/O with the recently introduced MacBook Pro line. Developed by Intel and brought to market with technical collaboration from Apple, Thunderbolt technology is designed to provide simple, yet powerful one-cable plug-in connectivity for 3G, HD/SD-SDI and HDMI workflows. Codenamed "Phaser", AJA's upcoming product supports HDMI 1.3a input and HDMI 1.4 output for stereo playback, provides 10-bit up/down/cross-conversions, with RS422 device control and professional reference/LTC I/O, in a highly portable design

Codenamed "Riker," AJA's multi-format I/O technology for everything from SD to 5K workflows, is designed to address rapidly changing I/O and processing requirements via its modular architecture. Riker offers an arbitrary hardware scalar that enables users to scale up or down any sized-raster (up to 5K) in realtime at full quality.

It connects to its host via high-speed 8-lane PCIe 2.0, over a 3-meter tether cable. AJA's new technology provides immense bandwidth, easily handling high-framerate 2K stereo 3D at up to 60Hz per eye, and even 4K stereo 3D at 24/30Hz per eye, says AJA President Nick Rashby. Riker delivers superior I/O, processing and scaling on the Mac and PC for complex multi-format 5K/4K/2K and HD/Dual-link/SD workflow, he adds.
