Ad Insertion Platform and Castlabs at NAB 2026

In late 2025, IAB Tech Lab released a formal set of standards for advanced streaming ad formats – the first significant update to ad format guidelines in several years. The move reflects a growing consensus: that the next wave of streaming monetization will not only be built on pre-roll and mid-roll, but on formats that integrate more naturally and creatively into the viewing experience.

STARDUSTmark v3 forensic watermarking updates

We’re excited to launch version 3 of STARDUSTmark featuring a practical update to our single-frame forensic watermarking pipeline. The core changes are in embedding and extraction: v3 is more resilient under real distribution transforms, while introducing less visible structure in the image than v2.
