We describe design and deployment infrastructure considerations for streamed delivery of multimedia. The
system addresses constraints introduced by variations in broadband network capacity, a rich variety of
playback devices, and content protection objectives. Streamed distribution, playback processing, and
conditions for resource consumption are described.
The constraints and design implications of streamed distribution and downloaded distribution of media are
described and compared. Server resources, client resources, and broadband connectivity considerations are
described, with the objective of supporting computer platforms and low-cost consumer electronics.
For playback of multimedia content we describe the use cases for full and partial media views, and the
digital rights considerations for authorized access from multiple playback devices. We describe client
device and server state interactions to support the resumed playback use case.
For time-based conditions and limitations for streamed media, we describe design considerations for
calculating resource availability, rights grants, and the customer experience for media interaction as
authorization windows reach their conclusion.
