CPC Class H04N

An encoding scheduling method, a server, a client, and a system for acquiring a remote desktop are provided. An encoding scheduling method includes: determining, by a server, encoding requirement information of an encoding task according to information reflecting a remote desktop creation requirement; and calling hardware encoding resources according to the encoding requirement information of the encoding task, to implement encoding of the encoding task.

Computer software that causes a stream processing management node to perform the following operations: (i) establishing data communication between the stream processing management node and a plurality of stream processing instances executing on respective computing environments in a multi-environment computing system; (ii) distributing one or more processing units of a stream processing job to a first set of stream processing instances of the plurality of stream processing instances; (iii) receiving, from the one or more stream processing instances of the first set of stream processing instances, processing results associated with the one or more processing units of the stream processing job; and (iv) performing a machine learning based stream management operation based, at least in part, on the received processing results.

An optical pattern in a real scene is decoded after acquiring a video stream using a camera of a mobile device, wherein the video stream comprises preview images of the real scene and the optical pattern is in the real scene. A viewport for a screen of the mobile device is defined. The viewport is overlayed on an application window. The video stream is presented in the viewport, wherein at least a portion of the optical pattern is depicted in the viewport. The optical pattern is decoded in one or more images of the real scene acquired by the camera.

A laying sheet is laid between a printing device configured to perform printing on a medium and an installation surface on which the printing device is installed. The laying sheet includes a first surface coming into contact with the installation surface and a second surface being a surface opposite to the first surface. The second surface is provided with at least one mark indicating information relating to the printing device.

Embodiments of the disclosure relate generally to imaging devices and indicia reading devices. An imaging apparatus comprises an image sensor, an optical window positioned in front of the image sensor and a light source enclosing a perimeter of the optical window such that an illumination cone of the light source overlaps a portion of a near field of view cone of the imaging apparatus. The portion of the near field of view cone extends from a surface of the optical window to a threshold distance from the optical window. The light source is configured to produce a first illumination along a first direction extending towards a scene to be imaged.

In an object tracking device, an object detection unit detects an object from video data using a plurality of object detection programs of different detection accuracy. The object tracking unit tracks the object from the detected position of the object by the object detection unit. The control unit controls the object detection programs used by the object detection unit based on the detection result of the object by the object detection unit and the tracking result of the object by the object tracking unit.
