Abstract: A method and apparatus for a streaming service to provide scalability and view information are provided. When a scalable video or multi-view video is transmitted using a Moving Picture Experts Group-2 (MPEG-2) system, scalability information or view information regarding the scalable video or multi-view video in a payload may be used. Using the scalability information or view information, a packetized scalable video or multi-view video may be efficiently adapted to various terminal performances, various network characteristics, a specific user preference, and the like.
