1. A server complied to Moving Picture Experts Group-Dynamic Adaptive Streaming over HTTP (MPEG-DASH) standard, the server comprising:
communication circuitry configured to communicate with a client; and
a processor coupled to the communication circuitry and configured to control the communication circuitry to:
receive, from the client, a Media Presentation Description (MPD) request including a first push directive having a first push type;
transmit, to the client, an MPD specified by the MPD request and at least one first segment; and
receive, from the client, a segment request including a second push directive, a second push type having the second push type different from the first push type, the segment request being generated by reference to the MPD, wherein
the at least one first segment includes at least one initialization segment selected in the server from among a plurality of initialization segments of respective representations, and
the first push directive indicates whether a media segment is included in the at least one first segment.
