Chapter 1 Product Overview
Overview
Note RTMP is part of the Flash Media Streaming feature and is part of Releases 2.0–2.3
3-Screen Session Shifting
Note 3-Screen Session Shifting is a Release 2.2 feature and supports RTSP streaming for the Windows Media
Engine and Movie Streamer Engine.
The 3-Screen Session Shifting feature unifies the user interactions with different content streaming
engines and enables seamless movement of user sessions to and from different client devices (PC, Mac,
Mobile, and TV). With this feature, users can pause a streaming session on one device and resume it on
a different device. This feature provides the intelligence for client detection and format selection. The
3-Screen Session Shifting interacts with the TV CDS as well.
3-Screen Session Shifting integrates with the delivery service configuration by linking three XML files
that interact with content management and transcoding systems to obtain device-type mappings and
content format mapping. 3-Screen Session Shifting works with entitlement servers to get the user
identification and uses the user identification as a key to store user sessions.
Session shifting from one client device to another device for a particular user requires the subscriber ID,
content ID, and last play time.
The Service Router acts as the centralized session manager for session shifting and maintains the session
database. The session database is populated by operator-generated 3-screen maps (XML files),
consisting of the Content map, Subscriber map, and Profile map. The XML schema for these different
