External services allocation in closed on-demand systems
Integrating external on-demand services is performed through embedding a pseudo on-demand video-title for each new on-demand external service, which is activated by an original session manager (SM) once a particular set-top converter box (STB), which belongs to a particular group_id, initiates a request for the external service. An STB application intercepts SM tuning information on the selected transport_id and service_id of the pseudo service and recovers the address of the selected edge device and QAM in the original system, associated with the intercepted transport_id, through the inverse mapping the couple (group_id, transport_id) to the edge and QAM IP and UDP port addresses which map is set by external management system. The STB application initiates the external on-demand service with same edge and QAM but with a different unique external_service_id , through streaming of the external service to the recovered edge IP address and to a new UDP port number where the new UDP port number encodes the original QAM address with the new unique external_service_id number of the external service, and tunes to the new external_service_id.
