Abstract: In one example, a processing system of a mobile computing device including at least one processor may capture visual information of a first location, transmit a recognition request to a first server, the recognition request comprising the visual information, obtain a first recognition result from the first server comprising first annotation content associated with a first item in the visual information of the first location, the first recognition result further comprising visual information of the first item, present at least a portion of first annotation content via the mobile computing device, store the first annotation content and the visual information of the first item in a local cache, detect a first additional mobile computing device via a non-cellular wireless communication modality, and share the first annotation content and the visual information of the first item with the first additional mobile computing device via the non-cellular wireless communication modality.

Abstract: An augmented reality device computationally processes an image frame against a first augmented reality profile stored in a local database. The first augmented reality profile includes first annotation content associated with a first object and is obtained from a second user device. In response to an object computationally processed from the first image frame satisfying a predetermined threshold of similarity with the first object in the first augmented reality profile, the first annotation content is rendered, on a display of the first user device, relative to the first object according to rendering instructions for the first annotation content.

Abstract: Aspects of the subject disclosure may include, for example, a device in which a processing system receives from a multimedia content server a plurality of content streams; each of the content streams includes a portion of an original content stream. The processing system transcodes the plurality of content streams based on a viewport prediction to produce a plurality of viewport streams; the viewport prediction is based at least in part on a visibility map associated with a viewer of the content. The processing system delivers each of the viewport streams to a client device associated with the viewer; each of the viewport streams is buffered at the client device in a separate buffer. Other embodiments are disclosed.

Abstract: A processing system having at least one processor may obtain a feature set from a camera frame of a client device, perform a feature reduction of the feature set to produce a reduced feature set, generate a compressed representation from the reduced feature set, compare the compressed representation of the reduced feature set to a plurality of compressed representations of known objects stored in one or more hash tables to identify an object in the camera frame, and provide an identification of the object to the client device.
