Abstract: 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.

Abstract: 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.

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: A tile concept allows independent encoding and decoding of regions of the video frames combined with changes in the way that the coded tiles are packetized and queued for transport. After the coded tile network abstraction layer (NAL) units are packetized into MPEG-TS frames, the more important tile data is put in the network abstraction layer at the head of the queue while the less important data is inserted later in the queue. Audio can also be accorded high priority. For a given link bandwidth/latency environment, the important data is transmitted first and the less important data can be discarded at the transmitter with less impact on the user perceived quality.
