Abstract: Various embodiments herein provide techniques for Session Description Protocol (SDP)-based signaling of camera calibration parameters for multiple video streams. In embodiments, a device may receive an SDP attribute to indicate that a bitstream included in a real-time transport protocol (RTP)-based media stream includes camera calibration parameters. The device may obtain the camera calibration parameters based on the SDP attribute, and process the RTP-based media stream based on the camera calibration parameters. In embodiments, the camera calibration parameters may be used to stitch together (e.g., align and/or synchronize) the multiple video streams. In embodiments, the stitched video streams may form an immersive video content (e.g., 360-degree video content). Other embodiments may be described and claimed.

Abstract: An input data structure of a first size may be converted to a plurality of data structures of a second size smaller than the first size. The data structures of the second size are realigned such that each of the plurality of data structures fits in one cache line. The realigned data structures are compiled for use in a vector machine.
