Despite of the recent progresses in reliable and high bandwidth communication, packet loss is still probable and needs special attention in real-time video streaming applications. Congestion and bit error rate, which sometimes are more than the protection capability of the channel codes, are the sources of packet loss in video communication. One common approach to deal with video packet loss is to use error concealment techniques, which estimate the non-received data as close as possible to the actual data. This article reviews the temporal video error concealment methods that have been developed over the past 30 years. The techniques are categorized into 8 groups, and the methods are covered with enough details. The strengths and weaknesses of the 8 groups are also tabulated, and some suggestions for future work and open areas for research are provided.

尽管最近在可靠和高带宽通信方面取得了进展，但是丢包仍然可能发生，并且在实时视频流应用中需要特别注意。拥塞和误码率有时甚至超过通道码的保护能力，它们是视频通信中丢包的根源。解决视频数据包丢失的一种常用方法是使用错误隐藏技术，该技术可以估计未接收到的数据尽可能接近实际数据。本文回顾了过去30年中开发的时间视频错误隐藏方法。将该技术分为8组，并在方法上详细介绍了这些方法。还列出了8个小组的优缺点，
