The document summarizes AARNet's experiences transmitting uncompressed high definition video between Canberra, Australia and Pittsburgh, USA during the Supercomputing 2004 conference. Key points include: - AARNet successfully transmitted 1.4 Gbps of uncompressed HD video between the two locations, equivalent to transmitting over 8 DVDs per minute. - The transmission used off-the-shelf components like Intel servers to capture, transmit, receive and display the video streams. - It was the first time live HD video was transmitted between the two countries, allowing participants in Pittsburgh and Canberra to communicate in real-time.
