1. A method of generating error correction for a video stream, the method comprising:

  • identifying a current portion of a current video stream, the current portion having a feature;

    identifying an estimated vulnerability metric based on a learned feature weight associated with the feature, the estimated vulnerability metric being a value based on comparing;

    a first decoded portion of an encoded training portion of at least one training video stream, the encoded portion including the feature; and

    a second decoded portion of the encoded training portion of the at least one training video stream, the second decoded portion based on the encoded training portion with a simulated transmission error; and

    generating an error correction code for the current portion based on the estimated vulnerability metric.
