Robust Header Compression (ROHC) offers a way to compress packet header information for more efficient transmission of data. The compression is achieved through various confidence modes set up by the transmitter and the receiver. The Initialization and Refresh state (IR) is the first state of the compressor. This provides a complete, uncompressed context of the data that is being transmitted. In typically operation, the ROHC compressor will periodically transmit IR packets providing context information allowing the ROHC decompressor to decompress one or more packets following the IR packet. However, under certain conditions such as decompressor start-up, it is possible for the decompressor to miss an IR packet. Exemplary methods and apparatus are described in which a decompressor uses a later-received IR packet to decompress earlier packets for which the decompressor had not received context information.

Method and device for correcting distortion errors due to accommodation effect in stereoscopic display
The invention concerns a method and a device for correcting distortion errors in a 3D content viewed by an observer on a screen. The method comprises the step of determining a rendered roundness factor (rrf) of a pinhole model projected cylinder, estimating a rendered roundness factor table depending on the defined distance of the observer to the screen and the disparity values of objects of the image, determining for the observer a disparity transform function (TD) as a function of the estimated rendered roundness factor table and modifying the object disparity values using the disparity transform so that a perceived roundness factor of one is provided.
Various implementations provide techniques to prevent excessive parallax, depth, or disparity from being passed through to a viewer. In one particular implementation, it is determined that a depth indicator for an object in a stereoscopic image pair of a video sequence is outside of a target range. One or more images of the stereoscopic image pair is modified so that the depth indicator for the object is within the target range. In other implementations, a depth transition between the object and another portion of the video sequence is smoothed. In further implementations, the stereoscopic image pair is replaced with a 2D image pair that includes the object. In yet further implementations, a resulting video sequence includes (i) one or more stereoscopic image pairs having non-zero disparity and for which the depth indicator is within the target range for the entire image pair, and (ii) one or more 2D image pairs.
A 3D model can be modeled using pattern-instance representation, wherein an instance component may be represented as transformation (for example, rotation, translation, and scaling) of a pattern. Quantization errors may be introduced when encoding rotation information, causing different vertex coordinate errors at different vertices of an instance. To efficiently compensate the vertex coordinate errors, an upper bound can be estimated for the vertex coordinate error of a vertex. Based on the upper bound, the codec decides whether the vertex coordinate error of the vertex needs to be compensated, and decides a quantization parameter for compensating the vertex coordinate error if compensation is needed. The upper bound can be estimated at both the encoder and decoder, and thus, no explicit signaling is needed to indicate whether vertex coordinate error compensation is used or to indicate the quantization parameter for the vertex coordinate error.

A particular implementation receives geometry data of a 3D mesh, and represents the geometry data with an octree. The particular implementation partitions the octree into three parts, wherein the symbols corresponding to the middle part of the octree are hierarchical entropy encoded. To partition the octree into three parts, different thresholds are used. Depending on whether a symbol associated with a node is an S1 symbol, the child node of the node is included in the middle part or the upper part of the octree. In hierarchical entropy encoding, a non-S1 symbol is first encoded as a pre-determined symbol ‘X’ using symbol set S2={S1, ‘X’} and the non-S1 symbol itself is then encoded using symbol set S0 (S2⊂S0), and an S1 symbol is encoded using symbol set S2. Another implementation defines corresponding hierarchical entropy decoding. A further implementation reconstructs the octree and restores the geometry data of a 3D mesh from the octree representation.

Method and device for processing of an image by regularization of total variation
The invention addresses the problem that traditional Total Variation only enforces the horizontal and vertical intensity continuity and thus fails to reconstruct oblique edges well. In an embodiment, Directional Total Variation is defined which supports multiple gradient directions. It first pre-processes the image and determines the direction of edges/texture; Directional TV is calculated based on the gradients along the determined direction and its orthogonal direction. By utilizing adaptive weights to different directions in the regularization, Directional TV is capable of preserving edges independent from their orientation nicely. Thus, Directional TV regularization based image denoising, compression or super resolution tend to obtain better quality.

Method and apparatus for customizing 3-dimensional effects of stereo content
A method and system for adjustable 3-dimensional content are described in which a viewer can adjust the depth range according to the viewer's own visual comfort level and/or viewing preference. The depth change is achieved by shifting the left and right images of stereoscopic content image pairs so that corresponding pixels in the shifted left and right images of a stereoscopic pair exhibit a new horizontal disparity sufficient to achieve the desired depth change. By shifting the left and right images in an image pair, content objects in the scene can appear closer to, or farther away from the viewer than those same objects in the un-shifted image pair. This technique achieves a viewer controlled customization of the sensation of depth in the stereoscopic 3-dimensional content.
n) via a set-top box (14). The set-top-box collects metadata identifying the audio-visual content viewed by the viewer and provides that metadata to a database (26) that searches for and identifies to the set-top-box the source(s) of alternative audio-if any. The set-top box will alert the viewer who can then select one of the identified sources of alternative audio in place of the audio embedded in the currently viewed audio-visual content.

Method and apparatus for searching in a layered hierarchical bit stream followed by replay, said bit stream including a base layer and at least one enhancement layer
A two-layer hierarchical audio bit stream can have a frame-based structure for the base layer bit stream and can be decoded independently from a higher layer and the decoding can start following every sync header. In the extension layer bit stream the frame structure may not be reflected on bit stream level. To facilitate seek operations with such highly compressed extension-layer data, the header of the extension layer bit stream comprises an FAT table with seek target positions. Because there are fewer entry points in the enhancement layer than sync headers in the base layer, a re-synchronization and some base layer frames are required to start decoding of the enhancement layer and to generate the full audio quality. Three seeking ways of seeking are described, of which each one offers a different compromise between seeking accuracy, re-synchronization latency and audio quality.
