Abstract: A key delivery mechanism that delivers keys to an OS platform (e.g., iOS platform) devices for decrypting encrypted HTTP live streaming data. An HTTPS URL for a stateless HTTPS service is included in the manifest for an encrypted HTTP live stream obtained by an application (e.g., a browser) on an OS platform device. The URL includes an encrypted key, for example as a query parameter value. The application passes the manifest to the OS. The OS contacts the HTTPS service to obtain the key using the URL indicated in the manifest. Since the encrypted key is a parameter of the URL, the encrypted key is provided to the HTTPS service along with information identifying the content. The HTTPS service decrypts the encrypted key and returns the decrypted key to the OS over HTTPS, thus eliminating the need for a database lookup at the HTTPS service.

Abstract: Various embodiments in this disclosure describe a method and a system for including advertisements in streaming content. For example, a manifest file may be accessed by a client device from a server device via a network, the manifest file including one or more media segment URLs and one or more advertisement markers arranged in a predetermined sequence. The advertisement markers included in the manifest file may be replaced by the client device with advertisement URLs associated with user-customized advertisements. The media segment URLs and the advertisement URLs included in the manifest file may then be sequentially accessed in accordance with the predetermined sequence.
