Abstract: An online system receives a media stream from a host of a live broadcasting stream and a second media stream from a guest of the host, and generates a single composite stream that includes the multiple live streams. The online system decodes and aligns the video and audio frames of each live stream to ensure that the composite stream displays the multiple live streams in a synchronized fashion. Additionally, the composite stream can display the multiple live streams in a particular format (e.g. side-by-side, or picture-in-picture), and therefore, the online system adjusts the video and audio frames of each live stream to fit that format. For each composite stream, the online system employs a decision engine that identifies the optimal set of encoded composite streams based on a variety of characteristics. The online system encodes the composite stream and distributes the appropriately encoded composite stream to client devices for display to viewers.

Abstract: A point cloud compression approach that exploits HEVC for compression of both the geometry and color data is described herein. Although both the geometry and color could be compressed in a lossy fashion, the point cloud compression approach is suggested for the scenario of lossless geometry and lossy color coding. Both geometry and color data are first mapped into 2D images and then compressed by HEVC. A sorting technique is used to sort the geometry data to make it as correlated as possible when it is mapped to a 2D image. For color coding, clustering is used to put similar colors in a point cloud into spatial neighbors in the mapped 2D image. This significantly avoids color leaking due to quantization errors to neighbor points in 3D. The results show that much better compression is achieved compared to the Anchor when it is configured for lossless geometry coding.
