![]() Also there would be an interrupt, which will cause increased usage (see above), and any sort of "thumbnail preview" like what youtube and netflix use would also slightly increase the bandwidth. Jumping around (skipping, re-winding, etc.) could also affect the usage - going forward past the buffer would reduce the amount of bandwidth used by a stream, but any re-winding would increase it. The same can be used for audio, especially where there isn't a fixed rate (i.e. This normally doesn't pop up much, but when a stream is paused/interrupted for whatever reason, this "history" is lost and will need to be re-transmitted, thus increasing the bandwidth, while with a download, it can be resumed at the "break", and assumed that the receiver already has this information. ![]() use that hue of blue from pixel X in frame Y), the less there needs to be sent. This means that the more history there is (i.e. It could also take more bandwidth depending on how the video is compressed - most of the time the entire image is not sent, rather just the change (or delta) between the frames. no throttling, frame-skipping, or lower-quality streams), then at best the streams will take the same amount of bandwidth as a download, although it could be done at a time/rate more convenient to the provider.
