Abstract: A wireless keyboard may be provided with a guard protocol which prevents unintended typematics. An alive signal may be periodically generated to advise a host processor-based system that the keyboard communication link is still effective. If the host processor-based system receives a key make signal but does not receive a break signal or an alive signal, the processor-based system may deduce that the link has gone inactive, and may generate its own break signal. This avoids unnecessary power consumption and unnecessary typematics.

Abstract: The media dependent module provides an interface between an upper-level conferencing driver (e.g., a data-link manager) of the conferencing system and a lower-level communications driver of the conferencing system to isolate the conferencing driver from the communications driver, where the media dependent module is dependent upon hardware of the communications driver. The media dependent module is adapted to perform a plurality of functions called by the conferencing driver. The media dependent module has a connection state machine. In a preferred embodiment, the communications driver is a communications stack that conforms to one of the NetBIOS, IPX, POTS Modem, and TAPI transport standards. The conferencing system may have multiple media dependent modules, each of which provides an interface between the data-link manager and a communications stack that conforms to a different transport standard.

Abstract: This disclosure describes techniques that can improve the generation of a decomposed multi-stream (DMS) by a host device of a video display system and the display of a DMS by a client device of the video display system. The techniques may apply different frame rates to different streams within a DMS, and the frame rates may depend on the content. For example, one stream within a DMS may comprise a sequence of full-motion video information, which may be rendered at a relatively high frame rate. However, another stream within the DMS may be associated with a background of the display, various graphic user interface control windows or elements, or a display window that includes non-video content (such as e-mail or a document). The second stream in the DMS may be rendered at a much slower frame rate than that used for the sequence of full-motion video information.

Abstract translation: 本公开描述了可以通过视频显示系统的主机设备改进生成分解的多流（DMS）的技术，以及由视频显示系统的客户端设备显示DMS。 这些技术可以对DMS内的不同流应用不同的帧速率，并且帧速率可以取决于内容。 例如，DMS内的一个流可以包括可以以相对高的帧速率呈现的全运动视频信息的序列。 然而，DMS内的另一个流可以与显示器的背景，各种图形用户界面控制窗口或元件或包括非视频内容（诸如电子邮件或文档）的显示窗口相关联。 DMS中的第二个流可以以比用于全动态视频信息序列的帧速率慢得多的帧速率来渲染。

Abstract: Wireless video transmissions over a MAC layer employ various techniques to improve throughput which may negatively impact latency, such as Block-ACK and data aggregation. To improve latency while continuing to improve throughput, data packets are fenced according to application layer specifications and then transmitted. For video data, Block-ACK sequences and aggregation sequences are terminated at the end of video frames or video slices. For data aggregation, a physical layer data packet concludes at the end of a video frame or slice. The application layer can indicate to the MAC layer when such packet fencing is to occur. In use with 802.11n transmission a data flag may be used by the MAC layer to facilitate fencing.

Abstract translation: MAC层上的无线视频传输采用各种技术来提高吞吐量，这可能会对等待时间造成负面影响，例如Block-ACK和数据聚合。 为了在持续提高吞吐量的同时提高延迟，数据包根据应用层规范进行围封，然后传输。 对于视频数据，Block-ACK序列和聚合序列在视频帧或视频片段结束时终止。 对于数据聚合，物理层数据分组在视频帧或分片结束时结束。 当发生这种分组防护时，应用层可以向MAC层指示。 在与802.11n传输一起使用时，MAC层可以使用数据标志来促进栅栏。
