Abstract:
A computing device (e.g., a content packager) may receive a request for content (e.g., video, audio, games, applications, data). The computing device may send a second request for the requested content to an encoder. In response to the second request, the computing device (e.g., the content packager) may receive the requested content and a content manifest associated with the requested content. The computing device may determine that encryption key data (e.g., an encryption key and/or key metadata) for the requested content is not in a cache associated with the computing device. The computing device (e.g., the content packager or a cache associated with the content packager) may send a request for the encryption key data associated with the requested content to a cache associated with a second computing device, based on the determination that the encryption key data is not in the cache associated with the computing device.
