Session Shifting and Delivery Services
The CDS uses the delivery services to implement most of its functions. Each delivery service is
associated with an origin server. A Content Origin in the CDS defines a Service Routing Domain Name,
which is used by the clients to receive the content delivery from the CDS platform. The Service Routing
Domain Name is only used for serving content. The Service Routing Domain Name configured for the
Content Origin should also be configured in the DNS servers, so client requests can get redirected to a
Service Router for request mediation and redirection.
The Web Services interface for session shifting is implemented on a per-delivery service basis. A Service
Router, identified by the Service Routing Domain Name, is designated as the centralized session
manager for each delivery service participating in session shifting. Only one Service Router is used for
all session shifting delivery services. A delivery service participating in session shifting can also be used
to deliver content.
Note The schemas used in the CDS for the Web Services interface follow the SCTE-130 standard and are
available upon request.
Content Manager
The Content Manager facilitates the management of content information for 3-Screen Session Shifting.
Content Lists can be posted to a Web Services interface in order to add or delete content. The provisioned
content is visible at a simple URL.
For example, for the delivery service with a Service Routing Domain Name of sr.cds.com, the following
link can be used to address the Content Manager to provision content:
http://sr.cds.com/api/services/content_mgr
Content Lists
Content Lists in XML format are used to add, append, and delete content entries through the delivery
service Session Shifting page. The following is an example of a Content List for a delivery service with
a Service Routing Domain Name of cds.com:
