我们引入了一种通过互联网的点对点视频传输方案，该方案将低延迟 TCP 友好的传输协议与具有容错性和带宽可扩展性的新颖压缩方法相结合。压缩视频被打包成单独的可解码数据包，这些数据包具有同等的预期视觉重要性。因此，在有损条件下，接收器可以实现相对稳定的视频质量。可以截断数据包以满足传输协议规定的随时间变化的带宽。实际的互联网实验与模拟一起用于评估整体方案的性能。
We introduce a point to point video transmission scheme over the Internet combining a low-delay TCP-friendly transport protocol in conjunction with a novel compression method that is error resilient and bandwidth scalable. Compressed video is packetized into individually decodable packets that are of equal expected visual importance. As a result, relatively constant video quality can be achieved at the receiver under lossy conditions. The packets can be truncated to meet the time varying bandwidth imposed by the transport protocol. Actual Internet experiments together with simulations are used to evaluate the performance of the overall scheme.
