Abrégé

Methods and apparatus for automatically transitioning program delivery/reception between alternative sources, e.g., from a non-IP channel to an IP video source or between two alternative IP sources are described. The transition maybe triggered by a detected problem with the delivery via the non-IP channel or because of scheduled service. The transition may be in response to a command sent to a device or because the receiving device detects a problem with one of the content sources triggering an automatic switch to the alternative content source. In at least some embodiments the different content sources corresponding to different coding methods, e.g., with MPEG-2 encoded and packetized content being delivered by a non-IP content delivery channel and MPEG-4 being delivered using unicast IP content delivery techniques. The methods facilitate deployment of new services with IP content delivery being deployed initially on a regional basis with non-IP content delivery gradually being rolled out.
