    • Data transfer is effected by a remote packet-communicating device to facilitate the transfer of data from a data source to another device that is local to the remote device. According to an example embodiment of the present invention, a host server provides access to a user's data source (e.g., at a registered user's PC) in response to a request from a remote packet-communicating device. The remote device directs the host server to facilitate the transfer of data from the data source to another device that is local to the remote device. In one implementation, a remote device and a media playback device are in communication on a local area network (LAN), and the remote device controls the communication of data from the data source to the media playback device, by interacting with a host server via a packet-communicating network and a gateway at the LAN.
    • 数据传输由远程分组通信设备实现,以便于将数据从数据源传输到远程设备本地的另一设备。 根据本发明的示例实施例,主机服务器响应于来自远程分组通信设备的请求,提供对用户数据源(例如,在注册用户的PC)的访问。 远程设备指示主机服务器以便于将数据从数据源传输到远程设备本地的另一设备。 在一个实施方式中,远程设备和媒体回放设备在局域网(LAN)上进行通信,并且远程设备通过与主机服务器通过与主服务器进行交互来控制数据从数据源到媒体回放设备的通信 分组通信网络和LAN上的网关。

    • According to an example embodiment, the present invention is directed to a video communication system having a user-friendly, intuitive-like control for altering the video camera view at a remote terminal. The local terminal includes a display and a movement-responsive sensor arranged to generate a direction signal in response to corresponding movement at the display. At least one of the first and second computer arrangements is configured and arranged to alter data being sent to the display in response to the direction signal from the movement-responsive sensor.

    • A videoconferencing system includes a videoconferencing arrangement with the capability to automatically determine whether a videoconferencing or conventional telephone call is being initiated. In one embodiment, a portable telephone unit includes a preprogrammed memory storing codes that indicate whether a telephone number input to the telephone unit should be used to initiate a videoconferencing or conventional telephone call. If a conventional telephone call is being initiated, the video processing functions of the videoconferencing unit are not activated and the user proceeds with the conventional telephone call. If a videoconferencing call is being initiated, the videoconferencing unit establishes a data connection with a compatible device at the remote end of the communications channel and proceeds with the videoconference. In another embodiment, a portable telephone unit interfaces with a remotely located switch circuit and the switch circuit determines whether the telephone call input to the portable telephone unit should be used to initiate a videoconferencing call or a conventional telephone call. The switch circuit includes a preprogrammed memory storing codes that indicate whether the telephone number input to the telephone unit should be used to initiate a videoconferencing or conventional telephone call.
    • 视频会议系统包括具有自动确定视频会议或常规电话呼叫是否被启动的能力的视频会议装置。 在一个实施例中,便携式电话单元包括存储代码的预编程存储器,其指示输入到电话单元的电话号码是否应用于发起视频会议或传统电话呼叫。 如果传统的电话呼叫正在发起,则视频会议单元的视频处理功能不被激活,并且用户继续传统的电话呼叫。 如果正在启动视频会议呼叫,则视频会议单元与通信信道的远端的兼容设备建立数据连接,并进行视频会议。 在另一个实施例中,便携式电话单元与远程位置的开关电路相连,并且开关电路确定输入到便携式电话单元的电话呼叫是否应用于发起视频会议呼叫或常规电话呼叫。 开关电路包括存储代码的预编程存储器,其指示输入到电话单元的电话号码是否应被用于发起视频会议或常规电话呼叫。

    • A computer workstation receives multiple audio input streams over a network in an audio conference. The audio input streams are kept separate by storing them in different queues. Digital samples from each of the queues are transferred to an audio adapter card 28 for output. A digital signal processor 46 on the audio adapter card multiplies each audio stream by its own weighting parameter, before summing the audio streams together for output. Thus the relative volume of each of the audio output streams can be controlled. For each block of audio data, the volume is calculated and displayed to the user, allowing the user to see the volume in each audio input stream independently. The user is also provided with volume control for each audio input stream, which effectively adjusts the weighting parameter, thereby allowing the user to alter the relative volumes of each speaker in the conference.
    • 计算机工作站通过音频会议中的网络接收多个音频输入流。 通过将音频输入流存储在不同的队列中来保持音频输入流的分离。 来自每个队列的数字样本被传送到音频适配器卡28以便输出。 音频适配器卡上的数字信号处理器46在将音频流相加在一起以输出之前,通过其自身的加权参数将每个音频流相乘。 因此,可以控制每个音频输出流的相对音量。 对于每个音频数据块,计算并显示给用户的音量,允许用户独立地查看每个音频输入流中的音量。 用户还为每个音频输入流提供音量控制,其有效地调整加权参数,从而允许用户改变会议中每个说话者的相对音量。
