    摘要: A video encoding method and apparatus are provided. The video encoding method includes determining whether a current block includes an affine-transformation object having an affine transformation; if the current block includes an affine-transformation object, generating a prediction block by performing affine transformation-based motion compensation on the current block in consideration of an affine transformation of the affine-transformation object; and if the current block does not include any affine-transformation object, generating a prediction block by performing motion vector-based motion compensation on the current block using a motion vector of the current block. Therefore, it is possible to achieve high video encoding/decoding efficiency even when a block to be encoded or decoded includes an affine transformation.

    摘要: Provided are domain contexts indicating user and device based domain systems for being applied to a new digital content protection/management system, and management methods thereof. A concept of “domain” is introduced in the present invention so that various business models can be obtained in accordance with content use of one home or small-sized group. The domain refers to as a group of user and device SAV and PAV indicating a context for being applied to the domain system includes: a domain identifier for specifying a domain as a region containing at least one content execution device and at least one content user; domain authentication information for guaranteeing authenticity of the domain; a user list containing information of users belonging to the domain; and a device list containing devices belonging to the domain.

    摘要: An apparatus and method for adapting a scalable video coding (SVC) bitstream is provided. The apparatus may include: a layer selection unit to select at least one quality layer from a plurality of quality layers contained in each of spatial layers of the SVC bitstream; a layer discarding unit to discard the at least one quality layer; and a layer dependency modification unit to modify a quality layer dependency between one or more quality layers remaining among the plurality of quality layers, or a spatial layer dependency between the plurality of spatial layers. Accordingly, it is possible to adapt the SVC bitstream where the entire quality of spatial layers is enhanced.
