Start-up Arroyo Video Solutions’ 1st external round of financing attracted some big MSO names-Time Warner Investments and Comcast Interactive Capital. Leading the $13mln funding round were DCM-Doll Capital Mgmt and Foundation Capital. Arroyo will go into trials with an unnamed MSO in the next few weeks. Details are being kept hush-hush (heck, Arroyo hasn’t even unveiled its product offerings publicly). Here’s what we know: Arroyo is developing a platform to deliver next-generation video services (on demand, HDTV, ITV). The platform would reside at the headend and be open standards based, with the goal of enabling MSOs and telcos to rapidly introduce new services.
