Abstract

In some embodiments, a method receives session features for a session associated with a request for a video from a client and predicts network conditions for the session using the session features. A subset of available profiles is selected based on the network conditions. The available profiles are associated with a different playback characteristic. The method provides a profile ladder that includes the subset of available profiles for the playback of the video to the client. The profile ladder restricts the client to using the subset of available profiles to request segments of the video during the session.
