I dont think they can - which is why despite being in breach of (at least) Youtubes TC's this practice is rife.
Thee are no inherent protocol differences between a download and stream, but there are some comon things a server could use -
- The number of chunks downloaded simultaneously.
- The speed the download occurs at.
- The size if the download relative to the reported screen size.
- Method of download - eg a streaming program may use TCP while reporting to be Chrome - when Chrome actually use QUICK
- Interpreting of Javascript
- Simultaneous downloads of multiple videos, or inadequate delays between downloads.
Ofcourse all of these can be emulated by a downloader - creating something of a cat and mouse game
There is, however, a biggie I dont believe is used by Youtube or Vimeo (but Netflix does) - DRM. This requires specific program or browser support, and us much harder to circumvent/immitate. Ofcourse, ths creates costs to deploy and rcreates barriers to view - and I expect Youtube etc business model is such that its not optimal for them.
