Abstract: Provided are a method and apparatus for transmitting or receiving data. The method includes obtaining information about first media data, the first media data including at least one component; and obtaining the at least one component based on the information about the first media data, wherein the information about the first media data further includes information indicating whether the at least one component is provided together with a component obtained from second media data.

Abstract: A method and apparatus for adaptively transmitting and receiving media data to a streaming environment by segmenting into segments a plurality of media data, which is generated by encoding content to have different qualities.

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: A peer-to-peer (P2P) network system is provided. The P2P network system includes a server which groups transmission unit packets constituting a data stream into a group according to a predetermined time unit and provides the group of the transmission unit packets, and a plurality of peer devices which transmit and receive the group of the transmission unit packets.

Abstract: Provided are an apparatus and method for sharing a broadcasting program, and more particularly, an apparatus and method for sharing a broadcasting program via the Internet. The apparatus includes a list manager which manages a list of devices storing a broadcasting program and a device information transmitter which transmits information, to a first device, about a second device storing a broadcasting program requested by the first device, wherein the second device divides the requested broadcasting program into time slots and transmits each time slot to the first device.

Abstract: Method and apparatus for receiving data by using a plurality of pieces of information managed by a server that manages information about data that can be received via one or more peer-to-peer (P2P) networks and information about peers respectively connected to each P2P network.

Abstract: Provided are a method and apparatus for transmitting/receiving broadcast data via a peer-to-peer (P2P) network, in which information regarding a list of a plurality of pieces of broadcast content that are broadcast via one broadcast channel is provided to a server in the P2P network, and the broadcast data is transmitted/received according to the provided list.

Abstract: Provided are a method and apparatus for providing and using content advisory (CA) information on Internet contents. A method of providing CA information by using a CA information server, includes receiving a request for the CA information on a content, from an Internet Protocol television (IPTV); searching for CA information on the content; and transmitting the found CA information to the IPTV. A method of using CA information when an IPTV reproduces a content not having the CA information, according to the present invention, includes transmitting a request for CA information, to a CA information server; receiving the CA information from the CA information server; analyzing the CA information; and applying the CA information.
