Abstract: A spectator experience corresponding to an occurrence of one or more games or events is generated based on each associated occurrence. The occurrence of a game or event varies in response to contributions and/or interactions of one or more participants of the game or event. The spectator experience enables users thereof to observe an augmented version of the game or event, such as by implementing enhanced viewpoint controls and/or other spectator related effects. In a particular aspect, the spectator experience can provide an indication of the spectators' presence, which is made available to the spectators and/or to the participants of the game.

Abstract: A system that captures both whiteboard content and audio signals of a meeting using a digital camera and a microphone. The system can be retrofit to any existing whiteboard. It computes the time stamps of pen strokes on the whiteboard by analyzing the sequence of captured snapshots. It also automatically produces a set of key frames representing all the written content on the whiteboard before each erasure. The whiteboard content serves as a visual index to efficiently browse the audio meeting. The system not only captures the whiteboard content, but also helps the users to view and manage the captured meeting content efficiently and securely.

Abstract: An adaptive "temporal audio scaler" is provided for automatically stretching and compressing frames of audio signals received across a packet-based network. Prior to stretching or compressing segments of a current frame, the temporal audio scaler first computes a pitch period for each frame for sizing signal templates used for matching operations in stretching and compressing segments. Further, the temporal audio scaler also determines the type or types of segments comprising each frame. These segment types include "voiced" segments, "unvoiced" segments, and "mixed" segments which include both voiced and unvoiced portions. The stretching or compression methods applied to segments of each frame are then dependent upon the type of segments comprising each frame. Further, the amount of stretching and compression applied to particular segments is automatically variable for minimizing signal artifacts while still ensuring that an overall target stretching or compression ratio is maintained for each frame.
