On March 10, 2026, CastLabs announced its attendance at the NAB Show 2026, where it plans to demonstrate technologies designed for protecting pre-release studio assets, enabling addressable ad innovation, and combating deepfakes within the media ecosystem. Previously, on March 5, 2026, CastLabs noted Google's upcoming discontinuation of its Widevine Cloud License Service (CLS) on April 13, 2027, urging users reliant on the service for Widevine DRM delivery to transition their architectures, clarifying that only the Google-hosted CLS endpoint is being retired. Earlier in March, on the 4th, CastLabs addressed the evolving challenges of Conditional Access Systems (CAS) in 2026, highlighting the financial and operational burdens traditional CAS designs impose on PayTV networks due to their fixed hardware and slow innovation cycles. This followed its February 11, 2026, commentary on the lack of standardized player error codes in streaming, which it identified as a significant factor contributing to confusion in Quality of Experience (QoE) due to varying reporting methods across platforms.
