ISBE2SpanningEvent Interface

[This documentation is preliminary and is subject to change.]

Implements spanning events for the Stream Buffer Engine, version 2 (SBE2), which supports the new Protected Broadcast Driver Architecture (PBDA). A spanning event is an event that exists until it is replaced or erased, and is part of the state for events that appear later in the same stream. Spanning events have a defined validity period within a Stream Buffer Interface file and may be recovered after a seek operation, updated, or deleted. Spanning events are intended for data with a defined lifespan, such as Digital Rights Management (DRM) keys, iTV DSM-CC data, or ratings information.

For more information about PBDA, download the specification from https://go.microsoft.com/fwlink/?LinkId=132926.
