摘要： A sensor data processing apparatus can be coupled to multiple image sensors of different types. The apparatus adjusts frame transmission rates based on the number of sensors and type of image data sourced by the sensors to optimize utilization of bandwidth on a number of transport channels. The apparatus can be configured to transport selected frames in the image data that are identified as critical frames at a higher rate than non-selected frames in the image data.

摘要： A communication control method for a SLAM device may include requesting an adjustment of a framerate of the sensor of the first device for obtaining additional image data or a request for an adjustment of image resolution, framerate or other parameters of additional image data to be received from the SLAM device, according to the speed of the SLAM device or a distance of the SLAM device from nearby objects. Also, map data of a device region of the SLAM device initially used for guiding the device may be updated if higher quality image data is received, to aid in improved navigating of the device region based on the updated map data.

摘要： Normalized resolutions are determined for first and second regions of interest of an initial video stream captured by a video capture device located within a physical space. The first region of interest is associated with a first conference participant within the physical space and the second region of interest is associated with a second conference participant within the physical space. Instructions are transmitted to the video capture device to cause the video capture device to capture, at the normalized resolutions, a first video stream associated with the first region of interest and a second video stream associated with the second region of interest. The first and second video streams conform sizes and quality levels of the first and second conference participants within separate user interface tiles of a conferencing software user interface to which the first and second video streams are output.

摘要： An encoding device evaluates a plurality of processing and/or post-processing algorithms and/or methods to be applied to a video stream, and signals a selected method, algorithm, class or category of methods/algorithms either in an encoded bitstream or as side information related to the encoded bitstream. A decoding device or post-processor utilizes the signaled algorithm or selects an algorithm/method based on the signaled method or algorithm. The selection is based, for example, on availability of the algorithm/method at the decoder/post-processor and/or cost of implementation. The video stream may comprise, for example, downsampled multiplexed stereoscopic images and the selected algorithm may include any of upconversion and/or error correction techniques that contribute to a restoration of the downsampled images.
