    • A computer-implemented method, to facilitate processing a payment for an online transaction, includes, responsive to receiving secure transaction data from a merchant server, using a payment processor to generate a transaction data identifier to identify the transaction data. The payment processor communicates the transaction data identifier to the merchant server. In response to receiving a request to process a payment, including the transaction data identifier, the payment processor requests user credentials from a user. Upon receiving user credentials from the user, the payment processor verifies the user credentials. The payment processor processes the payment and generates a payment identifier to identify payment data associated with the payment. The payment processor communicates the payment identifier to the merchant server. Upon receiving a request for payment data, including the payment identifier, over a secure communication channel from the merchant server, the payment processor communicates the payment data to the merchant server.
    • 计算机实现的方法,以便于处理在线交易的支付,包括响应于从商家服务器接收安全交易数据,使用支付处理器来生成交易数据标识符以识别交易数据。 支付处理器将交易数据标识符传送到商家服务器。 响应于接收到处理支付的请求(包括交易数据标识符),支付处理器从用户请求用户凭证。 在从用户接收到用户凭证时,支付处理器验证用户凭证。 支付处理器处理支付并产生支付标识符以识别与支付相关联的支付数据。 支付处理器将支付标识符传送给商家服务器。 在通过来自商家服务器的安全通信信道接收到包括支付标识符的支付数据请求时,支付处理器将支付数据传送到商家服务器。

    • A videoconferencing apparatus automatically tracks speakers in a room and dynamically switches between a controlled, people-view camera and a fixed, room-view camera. When no one is speaking, the apparatus shows the room view to the far-end. When there is a dominant speaker in the room, the apparatus directs the people-view camera at the dominant speaker and switches from the room-view camera to the people-view camera. When there is a new speaker in the room, the apparatus switches to the room-view camera first, directs the people-view camera at the new speaker, and then switches to the people-view camera directed at the new speaker. When there are two near-end speakers engaged in a conversation, the apparatus tracks and zooms-in the people-view camera so that both speakers are in view.
    • 视频会议设备自动跟踪房间中的扬声器,并在受控的人民摄像机和固定的室内摄像机之间动态切换。 当没有人在说话的时候,设备会显示到远端的房间视图。 当房间中有主导扬声器时,设备将人物摄像机引导到主扬声器,并从室内摄像机切换到人民摄像机。 当房间里有一个新的扬声器时,设备首先切换到室内摄像机,将人物摄像机引导到新的扬声器,然后切换到指向新扬声器的人物摄像机。 当有两个近端扬声器进行通话时,该设备将跟踪和放大人民摄像机,以便两个扬声器都在视野中。

    • A conferencing unit reduces or eliminates percussive noise in audio that it outputs to a far-end. The unit filters near-end audio into a plurality of bands and calculates instantaneous energies for each band. The energies in first and second ranges of the bands are summed, and a difference between the two sums is compared to a threshold value to determine whether speech is present in the near-end audio received. The first range is preferably a mid-band range of frequencies of 300 to 600-Hz, while the second range is preferably an outer-band range of 100-Hz to 300-Hz and 600-Hz to 14-kHz. Based on the determination, the conferencing unit adjusts an output level of the near-end audio to reduce or eliminate any percussive noise in output audio while there is not a substantial amount of speech in the near-end audio.
    • 会议单元减少或消除音频中的冲击噪声,从而将其输出到远端。 该单元将近端音频滤波成多个频带并计算每个频带的瞬时能量。 将频带的第一和第二范围的能量相加,并将两个和之间的差与阈值进行比较,以确定是否存在接收的近端音频中的语音。 第一范围优选为300至600Hz的中频带范围,而第二范围优选为100Hz至300Hz和600Hz至14kHz的外频带范围。 基于该确定,会议单元调整近端音频的输出电平以减少或消除输出音频中的任何冲击噪声,而近端音频中没有大量语音。
