    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.

    摘要: An apparatus for truncating fine granular scalability (FGS) data of a scalable video coding (SVC) video, the apparatus including: a rate-distortion (R-D) data extractor analyzing a bitstream to extract R-D data of at least one spatial layer; a user preference collector collecting user preference information associated with each spatial layer; a decision engine unit deciding an optimal bitrate of each spatial layer based on the R-D data and the collected user preference information; and a scaling engine unit truncating FGS data that does not correspond to the optimal bitrate of each spatial layer is provided.

    摘要: Provided is a method and apparatus for accessing service discovery metadata. Advance Internet Protocol Television (AIT) devices may access discovery metadata of different schemes using a generic protocol based on the moving picture experts group (MPEG) Extensible Middleware (MXM). According to the above access scheme, end-user devices, description service provider devices, and IPTV service provider devices may exchange metadata. Subsequent modification and addition of a metadata scheme may be supported.
