Abstract
A media content pipeline architecture is described that enables media devices to efficiently receive, store, play, and stream media content. In general, a media content pipeline as described herein is configured to receive media content streams from one or more input sources, segment and store the media content streams into fixed-sized or variable-sized data buffers, encrypt the data stored in the buffers, and store the encrypted data in an in-memory buffer cache for further processing. The media content pipeline further may be configured to write the encrypted buffers stored in the in-memory buffer cache to a secondary storage device (e.g., a hard disk) in response to the occurrence of one or more defined operating conditions. The media content pipeline may enable a media device to efficiently receive and process media content data streams, write the media content data streams to storage, and stream the media content data to client devices.
