(1) Data transfer is sensitive to data loss and bit errors, while delay and jitter are of relatively low importance. (2) In contrast, multimedia services are very sensitive to delay and jitter, whereas data loss and bit errors are of limited importance. (3) Some transmission schemes, such as those in ATSC and DVB, impose strict constant bit requirement on the transport stream. In order to ensure that the stream maintains a constant bitrate.
