Publication number: 20220385730Abstract: The disclosed technology is directed towards a rules engine that determines whether a content asset such as a movie is allowed to be downloaded to a device, such as for offline viewing. A rules engine receives information of a request to download a content asset to a device, in which the request is associated with a user identifier and a content asset identifier. The rules engine obtains a rule identifier via the asset identifier, which is used to obtain a ruleset. The rules engine obtains user download state information associated with the user identifier, and evaluates the ruleset and the download state information to determine whether to allow the download of the content asset. A ruleset can include entries such as total downloads allowed, total downloads allowed by a studio that owns the content asset, downloaded copies of the same asset allowed (e.g., to different user devices), and the like.Type: ApplicationFiled: May 25, 2021Publication date: December 1, 2022Inventors: Zheng Hua, James Boisseranc
