Abstract: An application-specific power management technique may establish a separate power-down interval for one or more applications based on user interaction with the one or more applications. In some implementations, during use of a particular application, when a management component determines that a period of user inactivity has become greater than or equal to the particular power-down interval established for the particular application, the management component may initiate a power down of one or more components, such as a display.

Abstract: This document describes a directed graph model using a peer-to-peer overlay structure and a gossip-based protocol to maintain the distributed membership. A protocol suite for peers to join the live streaming session, form the P2P streaming overlay, and exchange video packets with others has also been presented. The different capabilities of the heterogeneous peers are well depicted using an adaptive out-degree mechanism. The performance of the whole system is maintained by a contribution-aware mechanism, which ensures that the peers with large contribution will get more chance to be served than those with small or no contribution.

Abstract: An end-to-end lecture broadcast system (LBS) is described. The LBS system typically comprises three modules: a schedule module, a capture module and a transmission module. The schedule module is comprised of a scheduler that is implemented as a software add-on on the lecture host's computing device, a schedule server, and a schedule agent component in the uploading peer to provide for channel based management. The capture module is comprised of a video camera for capturing video content, one or more microphones for capturing audio content, and a VGA signal capture for capturing presentation materials. The transmission module is comprised of an uploading peer and a web server. The uploading peer is responsible for transmitting video/audio content to the Internet/intranet using peer-to-peer (P2P) streaming technology. The web server is responsible for the delivery of captured presentation materials and for ensuring the synchronous play back of video/audio content and presentation materials.

Abstract: Techniques described herein enable peers to determine each peer's NAT type much more efficiently and quickly than when compared with existing techniques. To do so, a peer simultaneously sends multiple test messages to a server. The peer then waits to either receive a response for each of the multiple test messages or may store an indication that no response has been received after a predetermined timeout period. The peer then analyzes the received responses and/or the stored timeout indications to determine the peer's NAT type or to determine that the peer is operating free from concealment by a NAT/firewall device. By simultaneously sending the multiple test messages, the peer may determine the NAT type within a maximum time defined by the predetermined timeout period or a roundtrip time period that is required for communication between the peer and the server. As such, the tools allow for efficient NAT-type detection.

Abstract translation: 本文描述的技术使得对等体能够比与现有技术相比更有效和快速地确定每个对等体的NAT类型。 为此，对等体同时向服务器发送多个测试消息。 然后，对等体等待接收多个测试消息中的每一个的响应，或者可以存储在预定的超时时段之后没有接收到响应的指示。 对等体然后分析接收到的响应和/或存储的超时指示以确定对等体的NAT类型或者确定对等体正在从NAT /防火墙设备的隐藏中运行。 通过同时发送多个测试消息，对等体可以在由对等体和服务器之间的通信所需的预定超时时间段或往返时间周期限定的最大时间内确定NAT类型。 因此，这些工具允许有效的NAT类型检测。
