US Patent 9571870 Automatic detection of preferences for subtitles and dubbing

In an approach, a server computer receives a request from a client computer specifying particular content for a particular user, wherein the particular content is associated with an original audio language. In response to receiving the request, the server computer selects a preferred audio language and a preferred subtitle language for the particular content based on a particular record of a preference database. The server computer returns asset identifying data that the client computer uses to obtain a stream of the particular content using the preferred audio language and the preferred subtitle language from a content delivery network (CDN) or other asset location. The server computer receives a message from the client computer that identifies an presented audio language and a presented subtitle language that were presented to the particular user while the particular content streamed. In response to a determination that the presented audio language differs from the preferred audio language or that the presented subtitle language differs from the preferred subtitle language, the server computer updates the particular record in the preference database.
