摘要： A method and apparatus for providing a trick play service in a hypertext transfer protocol (HTTP) adaptive streaming (HAS) architecture for adaptively streaming media data according to fluctuation of a streaming environment are provided. The method at a server includes: generating a media presentation description (MPD) file including information about at least one piece of trick play data; transmitting the MPD file to a client; and transmitting the at least one piece of trick play data to the client in response to a request by the client based on the MPD file. The method at a client includes: receiving a media presentation description (MPD) file including information about at least one piece of trick play data; and receiving the at least one piece of trick play data from a server based on the MPD file.

摘要： An information file pertaining to media data includes reproduction rating information for each of a plurality of segments. The information file is used by a client to determine what segment or segments to request from a server. The server responds to the request by sending the segment or segments to the client. Since the reproduction rating information may be provided for each of the segments, the selection of the segment or segments by the client can take into account a reproduction rating threshold.
