SYSTEM AND METHOD FOR SEGMENT DEMARCATION AND IDENTIFICATION IN ADAPTIVE STREAMING

摘要

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.
