    摘要： An interface for a networking device. A network interface module existing within a networking device monitors certain contacts of a network connection to identify a protocol of the networking system to which it is connected. Based on the detected protocol, the network interface module selects a set of configuration information with which to configure the networking device.

    摘要： A system is described that includes a real-time routing server to route and process multimedia sessions over a network. The system also includes a group server to manage the multimedia communications sessions over the network. The group server is coupled to the routing server. The system further includes a plurality of end-point processing devices to schedule and conduct multimedia communications sessions over the network. The plurality of end-point processing devices are coupled to the routing server and the group server. Protocols determine the topology of the network, reserve bandwidth, reserve media processing resources, and find the best route and the best real-time routing server to transfer and process multimedia data.

    摘要： A Multiservice Access Concentrator (MAC) provides a time limit for a first ringing voltage signal in response to an attempted call. The call is attempted via a voice over packet-data-network system (VOPS), wherein the VOPS comprises voice over Internet Protocol (IP), voice over Frame Relay, voice over Asynchronous Transfer Mode (ATM), and voice over High-level Data Link Control (HDLC) network systems. Generation of the first ringing voltage signal is terminated upon expiration of the time limit. A control message is transmitted to terminate the attempted call, wherein the control message is transmitted via the VOPS.

    摘要： Participants in a teleconference may exchange multimedia data, such as audio, video, documents, thumbnails, white board, buddy list, control data, etc., for example. The end-point devices may be located in different locations, may have different capabilities, such as processing power, amount of random access memory, amount of graphics memory, and display size, and the links among terminals may have different bandwidths. A real-time routing server may scale features available, such as video capture/encoding size, video decoding/display size, number of video display windows, quality of video pictures, whether to have thumbnails, etc., to the end-points based on the capabilities of the particular end-point device and/or its link bandwidth to the real-time routing server.

    摘要： A method is described for encoding video. A video sequence is captured at a full frame resolution. Boundaries for an inner region are identified within frames of the video sequence. The video sequence is encoded at the full frame resolution into a bitstream. The bitstream includes a sub-bitstream which encodes for the inner region. Data is embedded within the bitstream. The data identifies the sub-bitstream within the bitstream. In one aspect, the data is a header specifying the inner region. In another aspect, the encoding estimates motion for pixels within the inner region based on pixels within the inner region.

    摘要： A multimedia communication system in an Internet Protocol (IP) network includes broadcast capabilities. A system-wide emergency broadcast initiated by a user with the appropriate authority interrupts all teleconferences in progress. A group-wide high priority broadcast initiated by a user with the appropriate authority may interrupt some teleconferences in progress in the selected or other group(s). A group-wide normal priority broadcast allows all teleconferences to remain in progress and user may choose to join or not join the broadcast when the in-progress teleconference has ended.

    摘要： Embodiments are directed to systems and methods for delivering broadcast television (TV) using an Internet Protocol (IP) network. The IPTV system and methods use real-time routing servers to unicast and/or multicast of broadcast television programs. The IPTV system and methods may enable advertisers to insert local commercials into national or international television broadcasts. The IPTV system and methods offer network-based time-shifting of broadcast television programming rather than personal video recorder (PVR)-based time-shifting. The IPTV system and methods may provide scalable video on-demand (VOD) by multicasting video content and dynamically determining whether to speed up or slow down a bit stream to catch up to or wait for the previous or next multicast of the video content. The IPTV system and methods also may enables interactive television programming whereby a viewer may be permitted to exchange video with a television program and have that video displayed.
