Perfect Signal Synchronization: "PerfectSync"
(patent pending)

ADVC3000 not only incorporates the same video conversion technology present in the entire ADVC family of products, providing excellent reproduction of the source video footage, but also features PerfectSync technology. PerfectSync controls and synchronizes the transfer rate of IEEE 1394 communication with an external reference signal. This prevents skipped and duplicate frames and produces perfect conversion of all frames during analog/DV and SDI/DV conversion.

Many of the current DV converters adjust the output by skipping and/or duplicating frames in order to synchronize the DV signal to an external sync signal's frame frequency. In these converters, there is no guarantee that all input frames will output to DV accurately without frame repetition and/or frame drops. Since ADVC3000 is primarily designed for studio environments, frame accuracy is essential for accurate offline/online editing. With PerfectSync, this is assured.

VTR Control by AV/C-RS422 Conversion
ADVC3000 converts DV device control signals to RS422, to control an external VTR. Such control makes it possible to take in data from up to two professional VTRs, such as Digital Betacam, from any standard DV editing software that features DV device control.

Professional Video System Input
Reference input and LTC input/output can be utilized to create a professional video editing system with editors or switchers.

• Reference Input
• LTC input/output
• Reciprocal TC conversions (LTC, DVITC, DV)
• Frame accurate timecode conversion for LTC/DVITC/RS-422 to DV output
• DVITC line setting / automatic line detection

Comprehensive Audio Functionality
ADVC3000 can pass through or embed up to four channels of audio through the SDI output, making it possible to transfer professional level video/audio signals and connect to long distance transmission systems. ADVC3000 can also de-embed the audio from SDI input out to AES/EBU terminals, to support multi-channel audio operation with a professional audio mixer.

Other audio control features include individual digital audio peak meters, individual analog audio level knobs, balanced audio input/output headroom/level/600ohm termination, down-mixed two-channel output for audio monitoring, and the ability to combine video and audio from two difference sources and output to a single DV stream, complete with audio delay adjustment.

Analog Video Input Filtering
ADVC3000 also features built-in analog filtering technology to improve the quality of analog video input during conversion. Filtering options include 3D Y/C separation*, 3D noise reduction*, 2D Y and 2D C noise reduction, black/white gain adjust and horizontal/vertical outline enhancement.

*NTSC only

Proven DV Codec Technology
At the heart of ADVC3000 is the innovative Canopus DV codec chip, providing the industry's highest picture quality preservation during analog-to-DV conversion, and locked audio support for perfect audio and video synchronization at all times.

Advanced Usability
ADVC3000 is quickly configurable. The front-side dial and LCD display feature controls for Video and Audio I/O selection, aspect ratio, audio sample rates, audio delay, reference sync, RS422 control, color bar output, PerfectSync adjustments and more.

ADVC3000 can operate as a stand-alone device not requiring a computer, while keeping any preprogrammed settings.
