Abstract:
Provided is a method of transmitting and receiving personal broadcasting data in a peer-to-peer (P2P) based network. A terminal (client) that receives a personal broadcast requests a tracker server for a viewing reservation by using electronic program guide (EPG) information or a uniform resource locator (URL) of a personal broadcasting channel, a terminal (broadcaster) that transmits personal broadcasting data receives a list of clients that made a viewing reservation of the personal broadcast from the tracker server and notifies the clients about starting of the personal broadcast when it is time to start the personal broadcast. Accordingly, the client starts streaming when notified of the starting of the personal broadcast by connecting to the personal broadcasting channel after making the viewing reservation, without having to wait for the personal broadcast to start.

Abstract:
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.

Abstract:
Provided are a method and apparatus for limiting a content usage authority scope of a client by using metadata in an Internet Protocol Television (IPTV) service. The method performed by a metadata server adds control information to the metadata and transmits the metadata, wherein the content usage authority scope of the client is defined in the control information. The client of a user limits a content control operation according to a user input by using the control information extracted from the metadata.
