    • In a digital media pipeline, hardware-accelerated transform functions enable longer CPU idle time and a reduction in data transfer between the CPU and hardware, for the primary purpose of conserving power or increasing content security. Multiplexer/de-multiplexer functions can be configured as either stand-alone transform units or as plug-in components to a “pluggable” (host) media source or to a “pluggable” (host) media sink, so that the benefit of hardware acceleration can be applied to the source and sink as well as to the media foundation transform (MFT). Further data processing and control can be routed to a remote processing entity. The disclosed pluggable media source has a single input and one or more outputs; the pluggable media sink has one or more inputs and a single output. The pluggable media source and sink can be configured to accept plug-in components that support a wide range of data formats.
    • 在数字媒体流水线中,硬件加速转换功能可实现更长的CPU空闲时间,并降低CPU和硬件之间的数据传输,主要目的在于节省功耗或增加内容安全性。 多路复用器/去多路复用器功能可以被配置为独立的转换单元或作为“可插拔”(主机)媒体源或“可插拔”(主机))介质接收器的插件组件,从而使硬件 加速度可以应用于源和汇以及媒体基础变换(MFT)。 进一步的数据处理和控制可以被路由到远程处理实体。 所公开的可插拔媒体源具有单个输入和一个或多个输出; 可插拔介质接收器具有一个或多个输入和单个输出。 可插拔媒体源和接收器可以配置为接受支持各种数据格式的插件组件。
