Fantastic talk by Mary Wootters!
The question at 1:00:02 asked about combining the perceptual error-correction capabilities of humans with algebraic error-correction coding. I believe this direction is called Joint Source-Channel Coding: it takes into account that the source data being sent, such as images, video, or voice are to be interpreted by a human, so in each case, on the one hand the error-correction does not need to be as strict as to correct all errors, but on the other hand the errors that remain after correction must still be perceptually insignificant to a human. It is closely related to lossy compression methods such as mp3 for voice and sound, JPEG for images, and MPEG for video.

THANK YOU! After understanding Huffman error correction for 10 years, I finally understand Reed Solomon!

Referring to your comment at @33:53, do we have any state of the art technique now that can correct the transmitted message with insertion or deletion of symbols as data corruption?
