Improve network reliability, and / or, a method and apparatus for enabling a gradual deployment of video services

摘要

among alternative source, for example, the IP video source from a non-IP channels, or, between two alternative IP sources, describes a method and apparatus for automatically migrated program delivery / reception there. A problem that has been detected for delivery through a non-IP channels, or, for reasons of scheduled service, it is possible to trigger the migration. Transition, to perhaps one in response to commands sent to the device, or, that the receiving device has triggered an automatic switch to the content source alternative to detect a problem with one of the content sources It might be those of reason. In at least some embodiments, different content sources corresponds to a different coding method, for example, by non-IP content delivery channel, the content being packetized are MPEG-2 encoding is delivered, the unicast IP content delivery using the technology, MPEG-4 will be delivered. The method facilitates the deployment of new services, first IP content delivery is deployed in the region-based, gradually Non-IP content delivery is rolled outFIELD 8A
