When on-the-fly erasure code makes late video decoding happen.

This paper proposes \"LD-Tetrys\" (Late Decoding Tetrys), a solution based on an on-the-fly erasure code that attempts to solve the problem of late decoded packets usually considered as lost by the video decoder. LD-Tetrys has the following advantages: i) it drastically improves the trade-off between throughput and quality without modifying the codecs or adding complexity at the encoder side ii) it allows a simple but robust configuration. The only cost is a minor modification of the decoding process and a slight increase in the video decoding complexity. Last but not least, LD-Tetrys requires a much smaller playout buffer to obtain the same perceived video quality, bringing benefits for interactive applications.
