The Duet can be used with the Adtec adVantage™ Ad Insertion System for turnkey content management, alarm monitoring, schedule import and asrun log verifications.

     The Duet and Duet-SDI are MPEG2 digital commercial inserters which seamlessly play scheduled MPEG2 ads into an analog or a digital (SDI) main channel feed. The commercial inserters integrate with popular Traffic and Billing software solutions. When used with Adtec’s adVantage™ Ad Insertion System, they provide turnkey content management, alarm monitoring, schedule importing and as-run log verifications.
    The Duet-SDI inserts MPEG 2 commercials into a serial digital video (SDI) main channel feed with embedded AES-EBU audio. Designed for cable and broadcast operations with mixed SDI and analog systems, the Duet-SDI will provide SDI concurrent with analog video and audio output.

Broadcast Digital Commercial Insertion: The Duet can store thousands of MPEG 2 commercials that can be cued via GPI, DTMF, VBI or a timed schedule. Benefits Generate Revenue from Local Commercial Inserts: The Duet is known by operators as the “money machine” with a typical return on investment (ROI) within the first week of operation. Insert Commercials with Confidence: The Duet is a proven ad inserter that delivers reliable operation in over 20,000 network channels worldwide. Economically Scale to Hundreds of Channels: Unlike some competitive products, the Duet is a completely integrated single-channel commercial inserter that can be replicated to a distributed system with hundreds of channels. Integrate With Your Enterprise: The Duet can be used with the Adtec adManageTM system for turnkey content management, alarm monitoring, schedule import and asrun log verifications.
