21st Century 3D to Demonstrate Breakthrough Direct-to-Disk Stereoscopic Recording Technology at NAB 2006

4:4:4 uncompressed RGB 3D video camera utilizes high speed Seagate disk drives for recording.

21st Century 3D today announced that it will showcase the 3DVX3 camera system, the world’s smallest and lightest high-definition stereoscopic camera - recorder, at the National Association of Broadcasters convention (NAB), April 22-27 in Las Vegas. The 3DVX3 records a staggering 58 Mbytes/sec of stereoscopic video data to on-board, removable Seagate Momentus 7200.1 hard drives. While most digital camera systems measure their sustained data rates in Mbits/sec, the 3DVX3 records 1200% more data than most prosumer HD cameras, putting unprecedented demands on its storage subsystem.

Unlike many other direct to disk or direct to edit systems that record low bandwidth DV or HDV formatted video, the 3DVX3 records uncompressed RAW CCD data at 4:4:4 RGB in up to 10 bits per channel. Recorded simultaneously, each left and right eye video channel consists of 29Mbytes/sec of sustained data. This data flows from the camera’s A/D converters directly to two on board removable Seagate Momentus 7200.1 hard drives via two high speed USB data interfaces and two extensively modified Mac OS X CPUs.

Seagate’s 2.5-inch Momentus 7200.1 drives are compact and lightweight. They offer extremely high performance, and consume 48% less power than other drives 21st Century 3D tested. In addition, Momentus 7200.1 was the only model hard drive to sustain a write speed of 29Mb/sec over the entire disk surface – crucial to providing a full hour of recording time and extending operating duration from a single battery charge. Offered in capacities of up to 100GB, Momentus 7200.1 drives deliver a substantially longer record time than other 2.5” drives that were initially considered for use in the 3DVX3. The Momentus 7200.1 features a 7,200-rpm spin speed and 8mb on board cache that also makes it ideal for high-performance mobile workstations, non-mission-critical blade servers and small form factor PCs like the ones built in to the 3DVX3.

3DVX3 inventor and CEO of 21st Century 3D Jason Goodman said, “One of the keys to designing a successful system was the use of off the shelf components to the greatest extent possible. Selecting the correct ones proved to be a substantial challenge however. Throughout the course of development, we tried every brand and configuration of drive we could get our hands on. RAID configurations were tested too, but weight and size were critical design factors in creating the 3DVX3. Power consumption was a major issue as well. The sheer quantity of data being recorded dictated that the drives would need to be easily removable in a production situation. RAID arrangements offered good performance but poor battery life and they were neither compact nor convenient to deal with. A single drive (per eye view) solution was needed. The Seagate drives fit the bill on all accounts. A customized DC-DC regulator from Carnetix controls the power output from Anton/Bauer Dionic 160 batteries and the lower power consumption of the Seagate drives really helped extend operating time.”

NAB is the largest electronic media tradeshow in the world, and the 2006 event marks the first major public demonstration of 3DVX3 technology. 21st Century 3D will occupy booth C11631 in the Central Hall where they will be displaying the camera system as well as footage shot by the 3DVX3 in full color stereoscopic 3D.
