This diagram shows how the new DV5515 integrates with OctaStream modules via Sigma's Octabus. The DV5515 incorporates memory sufficient to delay high-definition video for up to 10 x 25Hz frames (400ms) and in excess of 50 frames at standard definition rates.

Sigma Electronics unveiled its DV5515 latency control module, an enhancement for the OctaStream family of AES digital audio signal management products, at IBC. The module provides the power necessary to solve video and audio signal latency problems encountered in broadcast and post production environments.

The new DV5515 is a unique digital video frame synchronizer that integrates with OctaStream modules via Sigma’s OctaBus. This allows for timing information to be read and compared between up to eight delay modules to realign the timing of HD, SD and AES signals. The DV5515 incorporates memory sufficient to delay high-definition video for up to 10 x 25Hz frames (400ms) and in excess of 50 frames at standard definition rates. This, combined with the ability to frame synchronize and re-align video frame boundaries across different signal formats, makes the DV5515 a powerful addition to the OctaStream family of products.



Sigma Electronics demonstrated the OctaStream family at IBC this year. The OctaStream family is engineered to provide unique solutions to the timing, mixing and synchronizing challenges inherent in the delivery of digital audio.

The OctaStream family, demonstrated at this year’s IBC, also offers the DA5320 Mixer and Subframe router that brings unique timing, mixing and synchronizing power to eight individual audio channels from four AES input streams; the DA5315 Variable Delay Compensator and DATC Comparator that sets variable delay up to 10 seconds for each of four independent AES signals over eight channels; the DA5325 Sample Rate Converter that serves as the audio equivalent of a video frame synchronizer; and the SG5605 AES and DATC Reference Generator, which provides an AES tone/silence with eight audible channel identifiers. The DV5515 is designed to seamlessly integrate into the OctaStream system, providing solutions to challenging timing problems.
