摘要： A method of compressing video content is disclosed and may include receiving an image frame of a video signal having multiple components, generating an edge-map for the image frame, generating a bitstream base layer for each component of the video signal, generating a first bitstream enhancement layer for each component of the video signal, and generating successive bitstream enhancement layers for each component of the video signal. As the successive bitstream enhancement layers are generated, the method of compressing video content goes from lossy to lossless.

摘要： Systems and methods identify a multi-hop network data path with sufficient available resources at each node along the data path to facilitate desired end-to-end data flow. Embodiments operate to identify resource constraints for meeting QoS or other communication requirements at each node of a multi-hop data path and propagate the resource constraint information within the network for use in identifying data paths suitable for supporting a desired end-to-end data flow. A resource allocation algorithm operable to allocate resources to achieve an end-to-end data flow meeting the communication requirements is implemented according to embodiments. A resource allocation algorithm of embodiments operates to ensure efficient use of the available resources so that desired conditions are satisfied when the resource requirements are met at each intermediate node for the upstream and downstream links and also both links simultaneously.

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： A method sends a signal to render visual information on a display, and receives a user response to the rendered visual information. The user response includes a first delay. The method also queries an electronic system for data indicating a second delay. The second delay is a portion of the first delay and attributable to the electronic system. The method further using the data indicating the second delay to compensate for electronic system delay during interactions with a user.

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.”

摘要翻译： 开发在通信网络中有效建立客户端设备之间的直接通信链路的技术存在挑战。 在一些实现中，相关联的STA是与特定接入点（AP）相关联的客户端设备。 非关联的STA是不与AP相关联的客户端设备。 隧道式探测请求可以由关联的STA通过AP发送以被广播到其他相关联的STA。 在一些实现中，活动扫描可以与隧道化探测请求组合，以建立相关联的STA和非关联STA之间的通信链路。
