ADS Tech's New Portable Dual-Link SDI Converter Delivers Bi-directional DV and SDI Transcoding in the Field
Posted Apr 25, 2005

ADS Tech has today its new portable Dual-Link SDI (Serial Digital Interface) Converter with embedded AES/EBU digital stereo audio functionality. The Dual-Link SDI transcoder is a 1394a bi-directional device that converts DV audio/video to and from SDI video, the broadcast standard digital interface. Windows XP and MAC OS X-compatible, the versatile device can be used with a portable battery pack, making it ideal for on-location news and event broadcasts, according to ADS.

With the Dual-link SDI Converter, camera operators have a cost-effective solution for Betacam transcoding, transporting content for NLE production and connecting to studio SDI network backbones or affiliate SDI matrices--all while leveraging legacy equipment. Designed for convenience and improved workflow, the compact device eliminates the wire clutter and the connector adaptors associated with using a DV camera to transcode.

The converter works with Betacam SX equivalents to the Sony BVW-55 Betacam SP Editing Recorder such as the DNW-A25 Betacam SX Portable Editing Recorder. In addition to being SMPTE-259M-compliant, the ADS Tech Dual-Link SDI transcoder is enhanced with an embedded audio transmitter and receiver that conform to the SMPTE 272M-A standard. The high picture quality of Dual-Link SDI is embedded with AES/EBU digital stereo audio with a sampling frequency of 48kHz (synchronous to video) to ensure high-quality audio.

Other features, such as the ability to adjust the default start-up options, let the user customize the device to speed workflow. A decode/encode switch is also included that allows users to change modes without being connected to a computer. With auto detection and support for both PAL and NTSC, the ADS Tech Dual-Link SDI Converter is built for international use.

Featuring a low-profile design, ADS Tech's Dual-Link Converter is housed in a rugged yet lightweight case designed for portability. The low-profile device features 4-pin and 6-pin 1394a ports for DV Input and output and two SDI BNCs for simultaneous SDI signal broadcast as well as separate VITC input and output BNC connectors (SMPTE 12M) for analog decks. A 4-pin DIP Mode select switch enables audio pair selection and other modes. The device can be powered using the 4-pin male latching XLR for battery input or the DC power adapter input. A 9-pin D subminiature is also included for RS-422 remote machine control per the Sony protocol.

ADS Tech's portable Dual-Link SDI Converter for Windows XP and MAC OS X systems has a MSRP of 999 and will be available through ADS Tech's network of online and retail channels worldwide by the end of April 2005.
