摘要： A communications task resides on an audio/communications board of the computer conferencing system. A communications manager and a communications application programming interface reside on a general-purpose host-processor of the computer conferencing system. The communications manager receives local compressed video signals from a video subsystem of the computer conferencing system and passes the local compressed video signals to the communications task. The communications task receives local compressed audio signals from an audio task of the computer conferencing system, the audio task residing on the audio/communications board. The communications task transmits the local compressed video signals and the local compressed audio signals over a communications link to a remote computer conferencing system. The communications task receives remote compressed video signals and remote compressed audio signals over the communications link from the remote computer conferencing system. The communications task passes the remote compressed audio signals directly to the audio task for decompression and playback processing. The communications task passes the remote compressed video signals to the video subsystem for decompression and playback processing.

摘要： A computer system for transmitting two or more types of signals. Each type of signal is assigned a priority level. Signals of a particular type are transmitted as they become ready for transmission, unless signals of a different type having a greater priority become ready for transmission. In that case, the transmission of the low-priority signals is interrupted to allow transmission of the high-priority signals. The transmission of the low-priority signals is resumed after the transmission of the high-priority signals is complete. In a preferred embodiment directed to conferencing systems, audio signals are assigned higher priorities than video, data, and control signals in order to provide a high-quality to the audio portion of a conferencing session.

摘要： There lies a challenge to develop a technique of effectively establishing a direct communication link between client devices in a communication network. In some implementations, an associated STA is a client device which is associated with a particular access point (AP). A non-associated STA is a client device which is not associated with the AP. A tunneled probe request may be transmitted by an associated STA through the AP to be broadcast to other associated STAs. In some implementations, an active scan may be combined with a tunneled probe request in order to establish a communication link between an associated STA and a non-associated STA.

摘要： A higher frame rate (a multiple of the original display frame rate at the host) is exploited at a display sink device to opportunistically insert new decoded frames for display at the higher refresh rate of the sink. In other words, delayed frames arriving at the sink may get a chance to be displayed during the higher refresh rate cycle, thus offering a better (“smoother”) viewing experience along with improved interactivity or “responsiveness.”

摘要： A power conservation method and system are provided for conserving power in client terminals by using a partitioned proxy server. The client terminal, having low-power and high-power communication interfaces, may power down its high-power communication interface to conserve power. Prior to shutting off its high-power communication interface, the client terminal may assign a partitioned proxy server to act as its proxy. The partitioned proxy server may include remote and local paging proxies which communicate with each other over an IP network. The remote paging proxy receives paging requests from an access point or the communication network and forwards it to the local paging proxy. The local paging proxy then forwards the paging message to the client terminal via a low-power communication interface. Upon receipt of the paging message via its low-power communication interface, the client terminal may power up its high-power communication interface and directly respond to the paging message.
摘要翻译：提供了一种省电方法和系统，用于通过使用分区代理服务器来节省客户端的功率。具有低功率和高功率通信接口的客户终端可以将其大功率通信接口断电以节省功率。在关闭其高功率通信接口之前，客户终端可以分配分区代理服务器来充当其代理。分区代理服务器可以包括通过IP网络彼此通信的远程和本地寻呼代理。远程寻呼代理从接入点或通信网络接收寻呼请求，并将其转发给本地寻呼代理。然后，本地寻呼代理器经由低功率通信接口将寻呼消息转发到客户终端。在通过其低功率通信接口接收到寻呼消息时，客户终端可以加电其高功率通信接口并直接响应寻呼消息。

摘要： Devices, systems and methods for optimizing a number of retransmission attempts in a multimedia environment and managing delays in a host MAC layer. In its various aspects, the presently claimed invention includes several methodologies and systems that are configured for determining an optimal retry limit in response to one or both of a packet error rate bound and a latency bound. To the extent that the retry limit is determined with respect to one of the aforementioned boundaries, the presently claimed invention may include determining a confidence level that the non-selected bound will also be met by the selected retry limit. The presently claimed invention details devices, systems and methods optimizing the number of retransmission attempts to ensure delivery of the selected data packets while guarding against undue delays and application disruptions.
