Cable operators are responding to their subscribers' insatiable appetite for TV programming with new innovative video solutions such as Cloud-DVR (cDVR) and TV Everywhere [1, 2]. cDVR solutions move in-home recording and playout functions to the cloud, and thus enabling remote access of the recorded Linear TV content on a variety of platforms such as laptops, tablets, cellphone, and TVs. cDVR has many advantages such as cost, performance, operation, and business intelligence compared with in-home DVR. For example, no truck-rolls are needed to deploy and fix cDVR issues. The cDVR service offers a virtually unlimited number of tuners, enabling customer to record more than two shows at a time, and providing completely scalable and redundant storage capability. This feature allows customers to easily increase the amount of paid storage without any changes to their home network. Furthermore, cDVR based solutions allow cable operators to deploy faster, and to use more cost-effective CPE devices such as Charter's Worldbox 2.0 with traditional and cloud-based interfaces [3].
