Abstract
Methods are disclosed for creating a virtual encryption session prior to video streaming content being requested to reduce or eliminate delay in initialization of the encryption session and content delivery to the customer. A virtual session has control word(s) (CW) and virtual entitlement control message(s) (ECM) that are devoid of content specific information. One or more virtual sessions may be stored at an edge device and may be used to encrypt the first portion of a content stream while a content-specific encryption session is being initiated.
