Abstract: Rendered portions of a renderable portion of a first view of a multi-view signal are introduced into a prediction loop of a multi-view encoder to form a reference signal for the block-based prediction of the encoder's view predictor may improve the prediction and thereby increasing the coding efficiency. The introduction may be performed by completely inserting the renderable portion into the prediction loop to form new reference pictures with their own reference picture indices in addition to reference pictures obtained by the reconstructed version of the multi-view signal of the block-based prediction. Alternatively, the rendered portion may be introduced into the prediction loop completely, but with replacing the normal prediction reference signal, i.e., the normally reconstructed signal as obtained by block-based prediction. Alternatively, it may be signaled within the data stream which portions of the renderable portion are used to replace respective portions in the normally reconstructed signal.

Abstract: A proposed intermediate way of handling the renderable portion of the first view results in more efficient coding. Instead of omitting the coding of the renderable portion completely, even more efficient coding of multi-view signals entails merely suppressing the coding of the residual signal within the renderable portion, whereas the prediction parameter coding still takes place from the non-renderable portion of the multi-view signal across the renderable portion so that prediction parameters for the renderable portion may be exploited for predicting parameters for the non-renderable portion. The additional coding rate for transmitting the prediction parameters for the renderable portion may be kept low as this merely aims at forming a continuation of the parameter history across the renderable portion to serve as a basis for prediction parameters of other portions of the multi-view signal.

Abstract: Reliable detection of input by a virtual-reality or augmented reality system is disclosed. Detection of input by the system may include displaying, via a display device, a stereoscopic rendering of a portion of a three-dimensional virtual environment including targets moving in predictable patterns. The rendering is updated based on movements tracked via a head tracker to show corresponding portions of the three-dimensional virtual environment along a gaze path through it. A first condition is detected if the gaze path corresponds to the movement one of the related targets along its pattern. Input is detected if, following detection of the first condition, it is detected that the gaze path also corresponds to the movement another of the targets along its pattern.
