I visited the SeaWell Networks booth at the recent NABShow and got a demo of their new network-based ad insertion capabilities from CEO Brian Collie. SeaWell's Spectrum technology helps service providers manage delivery of adaptive bit rate (ABR) streams to multiple devices, in partnership with ARRIS. At the NABShow, Brian demo'd how Spectrum can dynamically and seamlessly insert ads into video based on an individual user's behavior. SeaWell just completed an $8 million financing.
