The descriptor instantiationDataRate expresses the amount of data in a digital media file that is encoded, delivered or distributed, for every second of time. Although optimal data rates are often dependent on the codec used to compress and encode a digital file, generally speaking, a larger data rate translates into a better quality playback experience (e.g., 56 kilobits/second is lesser quality than 1 megabit/second).
