Master content directory service server for providing a consolidated network-wide content directory |
摘要 |
A master content directory service (CDS) provides a consolidated CDS which includes content listings representing all of the content within the network. A component of the master CDS functioning as a control point application periodically queries each CDS within the network in order to obtain the content listings for processing and inclusion within the master CDS. The component of the master CDS functioning as a control point application preferably also subscribes to each CDS within the network to receive notification of changes in content. Control point applications within the network access the consolidated master CDS to search content listings from all devices within the network. Preferably, the content itself is stored on the original device. When a control point application, accessing the master CDS, selects content for rendering, a communication is sent to the source device for the selected content. The selected content is then transmitted from the source device to the requesting device.
