Abstract:
A method for processing frames of data that are input to a data encoder when a loss of synchronization between the input data frames and the encoder is detected, comprising the steps of:monitoring the input data frames to detect a sync loss thereof in a sync loss frame;providing pre-sync loss input data of the input data frames to a data compressor of the encoder prior to detection of the sync loss;providing substitute data to the data compressor in synchronism with the pre-sync loss input data when the sync loss is detected to complete a remainder of the sync loss frame so that the sync loss frame is provided to the data compressor as a complete frame;monitoring the input data frames to detect a recovery of sync thereof; andproviding post-sync loss input data of the input data frames to the data compressor after the sync recovery is detected, and after a last frame including the substitute data is provided to the data compressor.
