Abstract
A method and system of message exchange for controlling flow associated with multimedia streaming services from a server to a client using DASH are disclosed. In one method, one or more Push Directives are sent from a client to a server to indicate information related to media data requested. At least one selected Push Directive uses one URLTemplate that comprises a list of media parameter values, and where each media parameter value corresponds to one media parameter associated with one media segment requested. The server then pushes one or more groups of data for the media data requested to the client according to the list of media parameter values. In another method, at least one selected Push Directive uses one URLTemplate that includes a first number to represent a number of repeating difference of media parameter values associated with requested media segments.
