• Best Practice. If possible, based on available bandwidth, it is better to use purpose built
devices (e.g., our family of 9000 encoders) to create the multiple bitrate necessary for
adaptive playback. Then, use the DME to combine and serve the streams.
• Best Practice. The act of transrating will always reduced the amount of "data" or quality
of the stream. While it is possible to upscale videos, that cannot ever add "data" but can
interpolate between existing data. If possible, start a transrate with a data stream larger
(resolution/bitrate) than the resulting stream.
• Best Practice. Test. Test. Test. Always pretest your source and any associated transrated
streams. Different sources can impart different characteristics within the stream which
may influence (good or bad) the transrate. If you have tested enough, test one more time
Note: DMEs 7550 and 7570 come standard with the Stream Conversion
feature. If you are on a DME 7530 and have licensed and activated the
Stream Conversion separately, it is critical that you monitor the CPU usage
of this feature. For more information see Activate Feature.
