ABSTRACT:
An MPEG data receiving apparatus adapted to interact with a MPEG data providing apparatus. A storage unit stores scene description information (SDI) from a received MPEG stream and a command recognition unit outputs node identification information based on user-selected objects and scene correction commands input by the user. A correcting unit searches for SDI stored in the storage unit corresponding to the scene correction commands and selectively updates the SDI on the object or requests the MPEG stream providing apparatus to update the SDI corresponding to the scene correction commands according to a result of determining whether the SDI corresponding to the scene correction commands exists in the storage unit. Accordingly, interaction between the MPEG data receiving apparatus and the MPEG data providing apparatus is enabled. Effective results are obtainable under a narrow bandwidth environment by reducing an amount of SDI transmitted from the providing apparatus.
