Abstract: An apparatus for converting a PCI/PCI X device into a PCI-Express device. The apparatus may include a first circuit configured to receive first data, wherein the first circuit is configured to translate the first data into PCI formatted data. The apparatus may also include a PCI data bus and a second circuit coupled to the first circuit via the PCI data bus. The second circuit is configured to receive the PCI formatted data from the first circuit via the PCI data bus. The second circuit is configured to translate the PCI formatted data received from the first circuit into PCI-Express formatted data. However, the PCI data bus transmits data between only the first and second circuits.

Abstract: An apparatus and method for use in a network including source clients and viewer clients connected to one or more shared transmission media. A video server is connected to one of the transmission media and is operative to control the broadcast and storage of multiple live or previously-stored video streams. The control may be provided via remote procedure call (RPC) commands transmitted between the server and the clients. In one embodiment, a video presentation system is provided in which a video stream from a source client is continuously broadcast to a number of viewer clients. One or more of the viewer clients may be authorized by the source client to broadcast an audio and/or video stream to the other clients receiving the source video stream. In another embodiment, a multicast directory is provided to each of a plurality of viewer clients by transmitting directory information in a packet corresponding to a predetermined multicast address.
