Sony debuts optical disc recording system

Available in the fall, the company says it expects the system to bring a revolutionary change to the world of broadcast news (ENG) and electronic field production (EFP).

“Our optical disc system will offer an entirely new paradigm in field acquisition and editing, in moving material at high-speed from the field to the television station to facilitate editing, and by introducing significant new efficiencies to a facility’s overall workflow,” says Steve Jacobs, senior VP of the broadcast and professional systems division of Sony Electronics’ Business Solutions and Systems Company.

The optical system records both the high-resolution original, and a lower-resolution but frame-accurate version called a proxy video and audio. The optical disc system will offer the choice of recording video with the DVCAM codec at 25 Mbps or the MPEG IMX codec at 30, 40, or 50 Mbps. Optical decks will accept both formats and offer the full range of analog A/V, digital A/V, and information technology (IT) standards, including compatibility with i.LINK (IEEE-1394) and Ethernet interfaces.

The optical media consists of a 12-centimeter (5-inch) re-writable disc in a protective cartridge; the two camcorders able to capture high-quality pictures with 2/3-inch EX HAD image sensors and 12-bit analog-to-digital converters; the battery-powered mobile deck which plays back DVCAM and MPEG IMX recordings and displays them on the built-in LCD monitor; a compact, NLE companion deck, a half-rack feeding/recording machine for nonlinear editing, which supports up to five times faster-than-real-time transfer of full-resolution DVCAM audio and video and up to 50 times real-time transfer of low-resolution proxy audio and video; and the studio deck, a standard editing deck that offers both DVCAM and MPEG IMX recording and playback, providing a full complement of analog A/V, digital A/V, and IT interfaces, including the i.LINK interface and Gigabit Ethernet port.
