Approximately seven years ago the teamat Cablevision envisioned a system whereour subscribers’ recorded content could bestored in a data center and played back overour network to their homes. The idea wouldeliminate the need for costly in homedevices and move to a cloud environment.We built a prototype that used commodityhardware along with a combination ofvendor and in house developed softwarethat would allow subscribers to createrecordings of their favorite shows and storethose programs on storage systems in ourheadend. After announcing our intentions,the content owners filed suit against us,claiming that our system was notpermissible under the copyright laws. Afterseveral years of litigation, the courtsvindicated the system, holding that it did notviolate the copyright laws.In January of 2011 we commerciallylaunched our Remote Storage DVR (RSDVR)product and marketed it as DVR Plus.Region by region we enabled cloud basedservices for all of our customers. This paperreviews the overall system and addressessome lessons learned. This will includeboth technical and operational detail onhow moving content recording and playbackto the cloud enables new features andportability for our customers. It will alsodefine how this platform is technicallyextensible to support multiple advancedstreaming services as well as Dynamic AdInsertion (DAI).Contributors: Thanks to Peter Caramanica,Rich Neil, Brad Feldman, and John Kennyfor their contributions to this paper.
