Abstract: Implementations may relate to various aspects of modifying, or using, a coded bitstream, or to recovering watermarking information from data. In one implementation, a coded bitstream is modified to allow for the application of a watermark to the coded bitstream without changing the coding of any other syntax elements in the bitstream. This is performed by identifying conditions necessary to change a coded syntax element without disrupting the interpretation of subsequent coded elements. The coded syntax element is replaced with another coded value if the modified value generates the same decoding variables as the original value would have generated. Particular implementations focus on syntax elements coded using entropy coding, including, for example, Context-based Adaptive Binary Arithmetic Coding (CABAC). Regardless of the type of coding or watermarking, various implementations may provide for recovering watermarking information.

Abstract: There are provided a method and apparatus for video error concealment in multi-view coded video using high level syntax. The apparatus includes a decoder for decoding pictures for at least one view corresponding to multi-view video content from a bitstream. The pictures are representative of at least a portion of a video sequence. At least some of the pictures correspond to different time instances in the video sequence. The decoder determines whether any of the pictures corresponding to a particular one of the different time instances are lost using an existing syntax element. The existing syntax element is for indicating a number of coded views in the bitstream, including the at least one view.

Abstract: The invention relates to a method, an apparatus, and a recording medium for recording multimedia content, which allow a controlled access to the multimedia content. According to the invention, the recording medium for recording multimedia content has a content limitation indicator for indicating which multimedia content is allowed to be recorded on the recording medium, which specifies an age rating for the multimedia content. A recording apparatus compares the multimedia content to be recorded with the limitations specified by the content limitation indicator prior to recording the multimedia content on the recording medium.

Abstract: There are provided methods and apparatus for block-based error concealment. An apparatus includes an error concealment module for concealing a current block in a lost picture in a group of pictures by using a last available inter-coded picture in a previous group of pictures, when the lost picture is a first inter-coded picture in the group of pictures. The group of pictures has a pattern characterized as an intra-coded picture followed by a sequence of inter-coded pictures.

Abstract: A method and an apparatus for bi-layer segmentation of an image or a sequence of images are described. A classifier is derived based on depth data of the image and another classifier is derived based on color data of the image. The image is then segmented by maximizing a weighted sum of matching scores derived from the classifiers based on depth data and color data of the image. The classifier based on color data of the image is derived using color sampling subsequent to generating an initial segmentation of the image.

Abstract: The apparatus includes a pickup for reading data from a super-resolution optical disc, the pickup comprising a laser for generating a main beam, a first and a second satellite beam, the two satellite beams each having a radial offset with regard to the main beam, a third satellite beam following the first satellite beam, having the same radial offset as the first satellite beam, and a fourth satellite beam following the second satellite beam, having the same radial offset as the second satellite beam, for providing a crosstalk correction of the HF data signal. The track pitch between adjacent tracks of the optical disc is particularly below the diffraction limit of the pickup, and the light intensity of each of the first and second satellite beams and of the main beam is sufficient to provide a super-resolution effect on the optical disc and the light intensity of each of the third and fourth satellite beams is not sufficient to provide the super-resolution effect.

Abstract: A particular implementation correlates a broadcast media item, which has a metadata element containing either a station call sign or channel number for a program, to a specific broadcast frequency and a virtual channel that a service provider broadcasts the program on. A command string is algorithmically defined to encode the frequency and physical channel, and is presented to the tuner hardware for locking onto and decoding the signal. A URL including the command string can then be generated. Consequently, a DLNA client device can engage a media renderer to play the broadcast media item through the exchange of a URL and a control interface.
