receiving a plurality of groups of data;
storing at least some of the received data in the buffer;
detecting an amount of data in the buffer;
removing at least a first subset of the data from the buffer; and
providing at least the first subset of the data to a receiver, including, if the detected amount of data in the buffer meets
a first criterion, repeating at least some of the data provided to the receiver,
wherein repeating at least some of the data comprises:
copying at least some of the received data in the buffer to obtain at least one data copy, without removing the copied data
from the buffer; and
inserting the data copy at a predetermined position in the first subset of the data provided to the receiver.
