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.

Abstract translation: 描述了媒体内容流水线架构，其使得媒体设备能够有效地接收，存储，播放和流式传输媒体内容。 通常，如本文所述的媒体内容流水线被配置为从一个或多个输入源接收媒体内容流，将媒体内容流分段并存储为固定大小或可变大小的数据缓冲器，对存储在缓冲器中的数据进行加密， 并将加密的数据存储在内存缓冲区高速缓存中用于进一步处理。 媒体内容流水线还可以被配置为响应于一个或多个所定义的操作条件的发生，将存储在内存中缓冲器高速缓存中的加密缓冲区写入辅助存储设备（例如，硬盘）。 媒体内容流水线可以使得媒体设备能够有效地接收和处理媒体内容数据流，将媒体内容数据流写入存储，并将媒体内容数据流传送到客户端设备。
