Difference From Other Technologies
The difference between SureStream and Bitrate Peeling is that SureStream is limited to only a handful of pre-defined bitrates, with significant difference between them, and SureStream encoded files are big because they contain all of the bitrates used, while Bitrate Peeling uses much smaller steps to change the available bitrate and quality, and only the highest bitrate is used to encode the file/stream, which results in smaller files on servers.
A related technique to the SureStream approach is hierarchical modulation, used in broadcast, where severally different streams at different qualities (and bitrates) are all broadcast, with the higher quality stream used if possible, with the lower quality streams fallen back on if not.

Famous quotes containing the word difference:
“I allude to these facts to show that, so far from the Supper being a tradition in which men are fully agreed, there has always been the widest room for difference of opinion upon this particular. Having recently given particular attention to this subject, I was led to the conclusion that Jesus did not intend to establish an institution for perpetual observance when he ate the Passover with his disciples; and further, to the opinion that it is not expedient to celebrate it as we do.”
—Ralph Waldo Emerson (1803–1882)
