System and method embodiments are provided for controlling end client behavior in dynamic adaptive streaming over hypertext transfer protocol (HTTP) (DASH). In an embodiment, the method includes receiving, at the end client, a DASH Motion Picture Experts Group (MPEG)-2 stream (TS) segment, wherein the DASH MPEG-2 TS segment includes segmentation descriptors, and performing, with the end client, an action, such as a media presentation description (MPD) reload, indicated by the segmentation descriptor. In an embodiment, the segmentation descriptor conforms to a Society of Cable Telecommunications Engineers (SCTE) 35 protocol or a HTTP live streaming (HLS) protocol.
