Abstract: System and method embodiments are provided herein for efficient representation and use of initialization vectors (IVs) for encrypted segments using template mode representation in Dynamic Adaptive Streaming over Hypertext Transfer Protocol (DASH). An embodiment method includes sending in a media presentation description (MPD), from a network server to a client, a template for generating a universal resource locator (URL) to obtain an IV that is used for encrypting a segment, in absence of an IV value in the MPD, receiving from the client a URL configured according to the template, and upon receiving the URL, returning an IV corresponding to the URL to the client. Another embodiment method includes receiving in a MPD, at a client from a network server, a template for generating a URL to obtain an IV that is used for encrypting a segment, upon detecting an absence of an IV value or IV base value in the MPD, configuring a URL for the IV using the template, sending the URL for the IV, and receiving an IV.
