    Abstract: Embodiments are provided for segment demarcation and identification in adaptive streaming by enabling marking chunks according to multiple standards simultaneously. An encoder boundary point (EBP) structure is used to indicate a plurality of partitions corresponding to a plurality of representations for a same content. A partition is a set of continuous chunks within a media stream of a defined length according to a corresponding standard. The EBP structure includes a bit-mask that is set to indicate one or more partitions in the stream. The EBP structure can indicate a boundary point for more than two partitions allowing a stream to be partitioned in several ways according to different standards. Additionally, a program map table (PMT) descriptor is used to describe each partition, providing information to process each partition. The PMT descriptor includes a packet identifier (PID) value for packets containing EBP structures.

    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.
