    • Audio in an audio conference is spatialized using either virtual sound-source positioning or sound-field capture. A spatial audio conference is provided between a local and remote parties using audio conferencing devices (ACDs) interconnected by a network. Each ACD captures spatial audio information from the local party, generates either one, or three or more, audio data streams which include the captured information, and transmits the generated stream(s) to each remote party. Each ACD also receives the generated audio data stream(s) transmitted from each of the remote parties, processes the received streams to generate a plurality of audio signals, and renders the signals to produce a sound-field that is perceived by the local party, where the sound-field includes the spatial audio information captured from the remote parties. A sound-field capture device is also provided which includes at least three directional microphones symmetrically configured about a center axis in a semicircular array.
    • 音频会议中的音频使用虚拟声源定位或声场捕获进行空间化。 使用由网络互连的音频会议设备(ACD)在本地和远程方之间提供空间音频会议。 每个ACD捕获来自本地方的空间音频信息,生成包括所捕获的信息的一个或三个或更多个音频数据流,并将生成的流发送到每个远程方。 每个ACD还接收从每个远程方发送的生成的音频数据流,处理所接收的流以产生多个音频信号,并且使信号产生由本地方感知的声场, 其中声场包括从远程方捕获的空间音频信息。 还提供了一种声场捕获装置,其包括围绕半圆形阵列的中心轴对称配置的至少三个定向麦克风。

    • A system and method for facilitating application sharing in a networked environment is provided. Specifically, the system divides a display area on a host computer into a plurality of regions, with each region comprised of a predetermined number of current pixels. The system then evaluates current pixels within a selected region and compares them to corresponding pixels stored in memory. If the system determines that the value of the current pixel differs from the value of the stored corresponding pixel, all pixels within the region are sent to a receiving computer via a network. The receiving computer inserts the received region into a display such that it matches the display on the host computer from which the region originated.
    • 提供了一种用于促进网络环境中的应用共享的系统和方法。 具体地说,系统将主计算机上的显示区域划分为多个区域,每个区域由预定数量的当前像素构成。 然后,系统评估所选区域内的当前像素并将其与存储在存储器中的相应像素进行比较。 如果系统确定当前像素的值与存储的相应像素的值不同,则该区域内的所有像素经由网络发送到接收计算机。 接收计算机将接收到的区域插入到显示器中,使得它与主区域起源的主计算机上的显示器相匹配。

    • A method, system and apparatus for application sharing smoothness when updating application screen imagery in an application sharing system. A shared application smoothness system can include an application sharing server configured for communicative coupling to multiple application sharing clients. The system further can include an application image update smoothness processor programmed to consolidate changes to adjacent image regions in an image of a shared application for transmission to the communicatively coupled application sharing clients in a single application image update interval. A shared application smoothness method can include the steps of detecting common shared image changes across multiple adjacent display regions of a shared application image and transmitting updates for the multiple adjacent display regions to communicatively coupled application sharing clients in a single image update interval.
    • 一种在应用程序共享系统中更新应用程序屏幕图像时应用程序共享平滑度的方法,系统和装置。 共享应用平滑系统可以包括配置为与多个应用共享客户端进行通信耦合的应用共享服务器。 该系统还可以包括应用图像更新平滑处理器,该应用程序图像更新平滑处理器被编程以整合在共享应用的图像中的相邻图像区域的改变,以在单个应用图像更新间隔中传送到通信耦合的应用共享客户端。 共享应用平滑方法可以包括以下步骤:跨共享应用图像的多个相邻显示区域检测公共共享图像变化,并且在单个图像更新间隔中将多个相邻显示区域的更新发送到通信耦合的应用共享客户端。
