Abstract

A client receives streaming data according to Moving Picture Experts Group-Dynamic Adaptive Streaming over HTTP (MPEG-DASH) standard. The client includes a transmitter which transmits a Media Presentation Description (MPD) request or a segment request to a server, and a receiver which receives an MPD specified in the MPD request and a segment specified in the segment request. The MPD request contains information requesting transmission of an initialization segment by a push. The receiver receives the initialization segment transmitted by the push.

First claim

The invention claimed is:

1. A client complied to Moving Picture Experts Group-Dynamic Adaptive Streaming over HTTP (MPEG-DASH) standard, the client comprising:
communication circuitry configured to communicate with a server; and
a processor coupled to the communication circuitry and configured to control the communication circuitry to:
transmit, to the server, a Media Presentation Description (MPD) request including a first push directive having a first push type;
receive, from the server, an MPD specified by the MPD request and at least one first segment; and
transmit, to the server, 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.
