摘要： Systems and methods are disclosed that facilitate real-time information exchange in a multimedia conferencing environment. Data Client(s) facilitate data collaboration between users and are maintained separately from audio/video (AV) Clients that provide real-time communication functionality. Data Clients can be remotely located with respect to one another and with respect to a server. A remote user Stand-in Device can be provided that comprises a display to present a remote user to local users, a digital automatic pan/tilt/zoom camera to capture imagery in, for example, a conference room and provide real-time information to an AV Client in a remote office, and a microphone array that can similarly provide real-time audio information from the conference room to an AV Client in the remote office. The invention further facilitates file transfer and presentation broadcast between Data Clients in a single location or in a plurality of disparate locations.

摘要： 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 spectator' presence, which is made available to the spectators and/or to the participants of the game.
摘要翻译：基于每个相关联的事件生成对应于一个或多个游戏或事件的发生的观众体验。游戏或事件的发生响应于游戏或事件的一个或多个参与者的贡献和/或交互而变化。观众体验使其用户能够观察游戏或事件的增强版本，例如通过实施增强的视点控制和/或其他观众相关效果。在特定方面，观众体验可以提供观众的存在的指示，这是向观众和/或游戏参与者提供的。

摘要： A program distribution system includes a plurality of set-top boxes that receive broadcast programming and segmentation data from content and information providers. The segmentation information indicates portions of programs that are to be included in skimmed or condensed versions of the received programming, and is produced using manual or automated methods. Automated methods include the use of ancillary production data to detect the most important parts of a program. A user interface allows a user to control time scale modification and skimming during playback, and also allows the user to easily browse to different points within the current program.

摘要： An erasure resilient coding (ERC) distributed data storage system and method for storing data in a reliable and survivable fashion while minimizing hardware and associated costs. The system and method includes forming multiple protection groups both within and across storage nodes of the storage system. Data is segmented into original data blocks and ERC data blocks. Load balancing occurs by interleaving storage nodes with equal numbers of original data blocks and ERC data blocks while ensuring each node has an equal number of combined read and write operations. Unique read and write operations on data block can be performed independent of other data blocks in a protection group. The write operation uses Galois field arithmetic and ERC transform to either write or append a new data block to a storage node. The read operation recovers data in a variety of ways using ERC decoding.

摘要： Architecture that scales up the non-negative matrix factorization (NMF) technique to a distributed NMF (denoted DNMF) to handle large matrices, for example, on a web scale that can include millions and billions of data points. To analyze web-scale data, DNMF is applied through parallelism on distributed computer clusters, for example, with thousands of machines. In order to maximize the parallelism and data locality, matrices are partitioned in the short dimension. The probabilistic DNMF can employ not only Gaussian and Poisson NMF techniques, but also exponential NMF for modeling web dyadic data (e.g., dwell time of a user on browsed web pages).
摘要翻译：将非负矩阵分解（NMF）技术扩展到分布式NMF（表示为DNMF）以处理大型矩阵的架构，例如，可以包括数百万和数十亿个数据点的网络规模。为了分析网络规模数据，DNMF通过并行性应用于分布式计算机集群，例如数千台机器。为了最大化并行度和数据局部性，矩阵在短维中被划分。概率DNMF不仅可以采用高斯和泊松NMF技术，还可以采用指数NMF来建模网络二进制数据（例如，用户在浏览的网页上的停留时间）。

摘要： An “adaptive audio playback controller” operates by decoding and reading received packets of an audio signal into a signal buffer. Samples of the decoded audio signal are then played out of the signal buffer according to the needs of a player device. Jitter control and packet loss concealment are accomplished by continuously analyzing buffer content in real-time, and determining whether to provide unmodified playback from the buffer contents, whether to compress buffer content, stretch buffer content, or whether to provide for packet loss concealment for overly delayed or lost packets as a function of buffer content. Further, the adaptive audio playback controller also determines where to stretch or compress particular frames or signal segments in the signal buffer, and how much to stretch or compress such segments in order to optimize perceived playback quality.
摘要翻译： “自适应音频播放控制器”通过将音频信号的接收分组解码并读取到信号缓冲器来进行操作。然后根据播放器设备的需要从信号缓冲器中播放经解码的音频信号的样本。抖动控制和分组丢失隐藏是通过实时连续分析缓冲区内容来实现的，并且确定是否从缓冲器内容中提供未修改的重放，是否压缩缓冲区内容，扩展缓冲区内容，还是提供丢包隐藏延迟或丢失的数据包作为缓冲区内容的函数。此外，自适应音频重放控制器还确定在哪里拉伸或压缩信号缓冲器中的特定帧或信号段，以及拉伸或压缩这些段以便优化感知的播放质量。
