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: The present invention relates to a quick release structure for a keyboard, which allows users to quickly remove and assemble the keyboard using a quick release ball structure between the top case and bottom case of the keyboard instead of tools and is more convenient compared to traditional keyboards requiring tools to remove ribbon cables and screws. Further, a PCB board is designed to connect to the Type-C interface inside the keyboard via a PIN magnetic connector. The PIN magnetic connector is an interface technique that uses magnetic force to achieve quick connection and disconnection. It usually consists of a magnetic male socket and a magnetic female socket with PINs, which are automatically connected via magnetic force. The quick release ball structure and PIN magnetic connector achieve ultimate quick release of the keyboard, making it convenient for keyboard maintenance and modification.
