    • A video conferencing system contains one or more display adjusting components, whereby an object to be displayed can be adjusted to appropriately fit various sized display screens. A display adjusting component is contained within the sending client, which adjusts the image of the object to be appropriately displayed to one or more receiving clients. The receiving clients also contain a display adjusting component, which can further adjust the image of the object to be displayed, as necessary. The multimedia conferencing server of the video conferencing system also contains a display adjusting component, which negotiates parameters of the sending and receiving clients. Any of the display adjusting components can function alone, or in any combination together. A method, and computer readable media which contain computer readable instructions to perform a method, of adjusting an image for video conference display are also described.
    • 视频会议系统包含一个或多个显示调整组件,由此可以调整要显示的对象以适当地适合各种尺寸的显示屏。 显示调整组件包含在发送客户端内,该调整组件将对象的图像调整为适当地显示给一个或多个接收客户端。 接收客户端还包含显示调整组件,可根据需要进一步调整要显示的对象的图像。 视频会议系统的多媒体会议服务器还包含一个显示调整组件,该组件协商发送和接收客户端的参数。 任何显示调节组件可以单独地或者以任何组合一起起作用。 还描述了一种包含用于执行视频会议显示的图像调整方法的计算机可读指令的方法和计算机可读介质。

    • A wireless communication device comprises a wireless communication interface, a user interface, and a processing system. The wireless communication interface is configured to receive streaming content from a communication system. The user interface is configured to display the streaming content in a plurality of windows. The processing system is configured to monitor a screen arrangement of the wireless communication device and determine an amount that each of the windows is covered, and if the amount exceeds a threshold value, to initiate a packet indicating a source packet address of the streaming content being displayed in the covered window. The wireless communication interface is further configured to transfer the packet to the communication system, wherein the communication system receives the packet, and in response, ceases transmission of the streaming content being displayed in the covered window to the wireless communication device.
    • 无线通信设备包括无线通信接口,用户界面和处理系统。 无线通信接口被配置为从通信系统接收流内容。 用户界面被配置为在多个窗口中显示流内容。 处理系统被配置为监视无线通信设备的屏幕布置并确定每个窗口被覆盖的量,并且如果该量超过阈值,则发起指示流内容的源分组地址的分组为 显示在被覆盖的窗口中。 无线通信接口还被配置为将分组传送到通信系统,其中通信系统接收分组,并且作为响应,停止在被覆盖的窗口中显示的流传输内容的传输到无线通信设备。

    • A synchronization tracking device and method in a code division multiple access (CDMA) receiver including oversampling received signals corresponding to a plurality of chips at a predetermined speed and sequentially storing the oversampled signals in a received signal shift register unit; sequentially storing pseudo noise codes generated in a pseudo noise code generator in a pseudo noise code shift register unit in a chip unit; correspondingly multiplying the output data from the received signal shift register unit and the pseudo noise codes outputted from the pseudo noise code shift register unit by means of a plurality of multipliers; adding the data outputted from the plurality of multipliers and storing the added result as the phase information and energy value for one path; repeatedly performing the above procedure until the phase information and energy values for all paths are stored; and selecting the path corresponding to a largest value in the stored phase information and energy values for all paths and informing a demodulator of the selected path. Thereby, the synchronization tracking device can reduce the time necessary for the synchronization tracking and continuously correct the information for a selected path, thereby improving the performance of the receiver.
    • 一种码分多址(CDMA)接收机中的同步跟踪装置和方法,包括以预定速度对与多个码片相对应的接收信号进行过采样,并将过采样信号顺序地存储在接收信号移位寄存器单元中; 将伪噪声码发生器中产生的伪噪声码顺序地存储在码片单元中的伪噪声码移位寄存器单元中; 通过多个乘法器相应地将来自接收信号移位寄存器单元的输出数据和从伪噪声码移位寄存器单元输出的伪噪声码相乘; 将从多个乘法器输出的数据相加并存储相加结果作为一个路径的相位信息和能量值; 重复执行上述过程直到存储所有路径的相位信息和能量值; 并且选择对应于所存储的相位信息中的最大值的路径和所有路径的能量值,并将所选择的路径通知解调器。 因此,同步跟踪装置可以减少同步跟踪所需的时间,并连续校正所选路径的信息,从而提高接收机的性能。
