  • Page 131: Fec Details

    Appendix FEC Details Matrix Size, Overhead, and Latency • FEC can only work if a single packet from each row/column is missing. Multiple packets missing from each row/ column will cause FEC to fail. • Due to the above, a smaller matrix is more robust, as there is a better chance of errors not occurring in the same row/column.

  • Page 132: Fec, Latency, And Lip Sync

    In order for FEC to work, the matrix must be filled in order to calculate the FEC packets. This introduces some additional latency. Due to high bitrates, this is not noticeable for video, but can be very significant for audio. Therefore, Atlona recommends either leaving FEC disabled for audio or using a very small matrix. •...
