Methods and apparatus for providing packetized content to users via a bandwidth-optimized network. In one embodiment, legacy and IPTV streams are carried over the same switched digital infrastructure, and freely intermixed without regard to their encoding or type. A user's selection for IPTV content is transmitted to an IP proxy (such as a gateway apparatus or a headend server), then on to the switched digital server which causes provision of the requested content back to the proxy for formatting. The formatted content is then delivered to the requesting IP-capable device. The entire carrier class program stream is therefore available as IP-encapsulated content to the IP capable devices (and as legacy content to legacy devices) without any significant modifications to the network infrastructure or bandwidth penalty.
