随着计算机和网络技术的迅速发展，高带宽流媒体应用现已在互联网上成为可能。然而，因特网并不提供支持高质量、实时多媒体传输所需的必要的服务质量（QoS）保证，导致因特网多媒体应用遭受延迟、抖动和丢失。其中，通常由网络拥塞引起的丢失最能降低多媒体流的感知质量。我们提出了一种视频交织的方法，改善了帧丢失的影响，通过传播的突发性影响的损失。发送方首先在传输前对数据进行重新排序，以帮助分配损失，然后在接收方将数据返回到原始顺序。我们将我们的方法应用于MPEG和评估的好处交织的感知质量与用户研究。我们的研究结果表明，交织增加了少量的延迟和带宽开销，同时显着提高互联网视频的感知质量。
With the rapid improvement in computer and network technologies, high-bandwidth streaming multimedia applications are now possible on the Internet. However, the Internet does not provide the necessary Quality of Service (QoS) guarantees needed to support high-quality, real-time multimedia transmission, causing Internet multimedia applications to suffer from delay, jitter and loss. Among these, loss, typically caused by network congestion, can degrade the perceptual quality of multimedia streams the most. We propose a video interleaving approach that ameliorates the effects of frame loss by spreading out the bursty effects of loss. The sender first re-sequences data before transmission to help distribute loss, and returns the data to their original order at the receiver. We apply our approach to MPEG and evaluate the benefits of interleaving to perceptual quality with user studies. Our results show that interleaving adds a small amount of delay and bandwidth overhead, while significantly improving the perceptual quality of Internet video.
