Abstract: A system, which uses the internet to deliver time sensitive information, includes an overlay node, having a plurality of overlay nodes, which are used to deliver the time sensitive information. To better characterize the connection between a sending node and a receiving node, the sending node periodically requests each overlay node in the path between the sending node and the receiving node to force a retransmission of a packet, while also forwarding that same packet to the next overlay node. In this way, the delay associated with each link in the path can be quantified and recorded by the receiving node. Based on the observed transmission delays, the receiving node may determine an optimal buffer time. This buffer time is the amount of buffering performed at the receiving node prior to outputting the time sensitive information.

Abstract: A system for remotely controlling a camera is disclosed. The system includes five major subsystems; a first subsystem collocated with the camera; a second subsystem which serves as a gateway between the camera and the third subsystem; a third subsystem to remotely monitor the studio and control the camera; a fourth subsystem located at the destination of the video stream; and a fifth subsystem to receive and re-transmit a video control stream. This system allows the camera to be monitored and controlled by one location, while the primary video stream is transmitted to a different location. In some embodiments, the control video stream is a lower bandwidth signal than the primary video stream. Furthermore, the fifth subsystem is capable of receiving and re-transmitting control video streams from a plurality of cameras simultaneously. The second subsystem allows remote access to the first subsystem, such as via the third subsystem, based on approved credentials.

Abstract: A system and method for delivering content over the Internet from a content source to a destination is disclosed which includes the use of an overlay network, built on an underlying IP network. Additionally, error correction capability is added to the overlay network to allow the destination to reconstitute packets lost during the transmission over the Internet. In one embodiment, an overlay network is created using a plurality of overlay nodes, which may be geographically distributed, either throughout the country or throughout the world. Each respective content source or destination is also a part of the overlay network. Overhead, capable of providing error correction capability, is added to the content flow as it enters the overlay network. As the content flow leaves the overlay network, this overhead is removed from the content flow. In the case of transmission errors across the overlay network, the overhead information is used to reconstitute lost or corrupted packets.
