Subscription and channel management technology, in which a system allows a user to subscribe to a subset of the available channels on a content delivery network and personalize at least one channel. The system identifies a user identity of the user and stores, in a user database, channel subscription information for the user identity based on the subset of channels to which the user subscribed and the user personalization. The system identifies a downloader device associated with the user identity and controls the downloader device based on the channel subscription information stored in the user database.
