Abstract: Marking a keyframe of a media stream in a communication system involves one or more entry media switches in communication with one or more endpoints. An entry media switch receives a media stream from an endpoint, where the media stream comprises a sequence of packets with a keyframe. The keyframe is detected and marked with a keyframe indicator. The keyframe indicator is operable to notify a downstream device of the keyframe. An output media stream is outputted.

Abstract: Synchronizing audio and video streams in packet-based networks requires synchronization of packet timestamps. The present invention provides such synchronization without resort to a network time standard. In one embodiment of the present invention, pairs of timestamp synchronized signals, such as audio and video signals, not having a common timestamp clock are mixed. One of the signals, for example, the audio signals, is mixed first while preserving the original audio timestamps. The preserved timestamp information is then used to synchronize the timestamps of the unmixed signals, in this example the video signals, to provide synchronization of all signals. In another embodiment, the present invention uses packets containing calibration of timestamps to reduce jitter. The present invention also includes specifications for a packet for transmitting timestamp information.

Abstract: In one embodiment, an apparatus includes two modules. A first module receives a request from a first endpoint to subscribe to a voice activated multicast group and causes the first endpoint to receive a current speaker's video stream if the first endpoint is not the current speaker and to receive a last speaker's video stream if the first endpoint is the current speaker. A second module receives a request from a second endpoint to subscribe to a continuous presence multicast group and causes the second endpoint to receive a continuous presence, current speaker video stream if the second endpoint is not the current speaker and to receive a continuous presence, last speaker video stream if the second endpoint is the current speaker. The continuous presence, current speaker video stream includes a composition or two or more video streams, one of which includes at least a portion of the current speaker's video stream. The continuous presence, last speaker video stream includes a composition or two or more video streams, one of which includes at least a portion of a last speaker's video stream.

Abstract: Disclosed is an active or dynamic RFID tag that actively provides current status information regarding a particular item, as well as mechanisms for recognizing dynamic RFID information read from such RFID tag. Static identifying information regarding the particular item is provided either by the same active/dynamic RFID tag or by a different passive RFID tag. While the RFID tag may passively or actively provide general identification, the RFID tag actively provides status information that corresponds to changes in the corresponding item's status. In a first implementation, active RFID tags are positioned next to one or more components within a system so that each active RFID tag is powered and transmitting its RFID information when its corresponding component is operational. In contrast, each active RFID tag is positioned so that it is not powered and not transmitting its RFID information when its component is failing. Accordingly, an RFID reader can then know when a system has a failing component when one of the component's corresponding active RFID tag is not transmitting its RFID information. In this first implementation, the active RFID tag either transmits or fails to transmit based on its component's status state. In a second implementation, a dynamic RFID is associated with a specific component, set of components, or system, and the dynamic RFID tag dynamically provides an RFID reader with RFID information that changes with its associated item's changing status state. The status state may correspond to any suitable parameter of the item or product that can change over time. Thus, the dynamic RFID provides different transmission frequencies based on different status states of its component or system.

Abstract translation: 公开了主动或动态RFID标签，其主动地提供关于特定项目的当前状态信息，以及用于识别从这种RFID标签读取的动态RFID信息的机制。 关于特定项目的静态识别信息由相同的主动/动态RFID标签或不同的无源RFID标签提供。 当RFID标签可以被动地或主动地提供一般标识时，RFID标签主动地提供对应于相应项目状态的变化的状态信息。 在第一实现中，有源RFID标签位于系统内的一个或多个部件的旁边，使得每个有源RFID标签被供电并在其相应的部件可操作时传送其RFID信息。 相比之下，每个有源RFID标签被定位成当其组件出现故障时它不被供电并且不发送其RFID信息。 因此，当组件的相应的有源RFID标签中的一个不发送其RFID信息时，RFID读取器可以知道何时系统具有故障组件。 在该第一实现中，有源RFID标签基于其组件的状态来传输或不发送。 在第二实施例中，动态RFID与特定组件，组件或系统集合相关联，并且动态RFID标签动态地向RFID读取器提供随其相关联项目的改变状态状态而改变的RFID信息。 状态可以对应于可随时间变化的物品或产品的任何合适的参数。 因此，动态RFID基于其组件或系统的不同状态提供不同的传输频率。
