Abstract: Saliency regions are identified in a global scene depicted by volumetric video. Saliency video streams that track the saliency regions are generated. Each saliency video stream tracks a respective saliency region. A saliency stream based representation of the volumetric video is generated to include the saliency video streams. The saliency stream based representation of the volumetric video is transmitted to a video streaming client.

Abstract: An optical transmitter comprises a directly coupled MZ interferometer and driver circuit. The MZ interferometer comprises a pair of differentially driven MZ electrodes configured to impart RF signals to light travelling through respective arms of the interferometer, and to receive DC bias as a positive voltage via lower n-type cladding of the MZ interferometer. The lower n-type cladding is at a different positive DC potential to an upper plane RF ground of the MZ interferometer, but the lower n-type cladding and the upper plane RF ground have similar AC potential. The MZ interferometer also comprises a pair of resistors in series configured to provide differential RF termination of the MZ electrodes; and a capacitive coupling between a virtual ground formed at a centre point between the pair of resistors and an RF ground configured to provide common-mode RF termination. The DC supply for the driver circuit is applied to the centre point of the RF termination.

Abstract: Methods and apparatus for dynamic modification of interruptibility settings of network-accessible resources are disclosed. A system includes a resource manager and a plurality of resource instances, each of which has an interruptibility setting. In response to an instance acquisition request, the resource manager allocates an instance with a first interruptibility setting, allowing the resource manager to revoke the client's access to the instance without a notification. In response to an approval of an interruptibility upgrade request, the resource manager modifies the interruptibility setting to a second setting that allows the client to retain access to the instance for at least a specified time. Respective billing amounts for the client's use of the instance are determined for each of the interruptibility settings used.

Abstract: Apparatus and methods are provided that employ one or more of a variety of techniques for reducing the time required to display high resolution images on a high dynamic range display having a light source layer and a display layer. In one technique, the image resolution is reduced, an effective luminance pattern is determined for the reduced resolution image, and the resolution of the effective luminance pattern is then increased to the resolution of the display layer. In another technique, the light source layer's point spread function is decomposed into a plurality of components, and an effective luminance pattern is determined for each component. The effective luminance patterns are then combined to produce a total effective luminance pattern. Additional image display time reduction techniques are provided.

Abstract: In a multi-tenant web services platform, a request is received from a first customer requesting that a second customer be allowed to use a computing resource associated with the first customer. Control of the computing resource is transferred to the second customer based on a constraint selected by the first customer. A first portion of a cost associated with the computing resource is billed to the first customer. The control of the computing resource by the second customer is terminated in accordance with the constraint selected by the first customer.

Abstract: A data structure defining a high dynamic range image comprises a tone map having a reduced dynamic range and HDR information. The high dynamic range image can be reconstructed from the tone map and the HDR information. The data structure can be backwards compatible with legacy hardware or software viewers. The data structure may comprise a JFIF file having the tone map encoded as a JPEG image with the HDR information in an application extension or comment field of the JFIF file, or a MPEG file having the tone map encoded as a MPEG image with the HDR information in a video or audio channel of the MPEG file. Apparatus and methods for encoding or decoding the data structure may apply pre- or post correction to compensate for lossy encoding of the high dynamic range information.
