Abstract

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.
