1. A method of operating a content distribution network to deliver both and Internet Protocol (IP) packetized content and legacy non-IP encoded content via a switched digital system, said method comprising:

  • receiving data indicative of a request for said IP packetized content at said switched digital system, said data indicative of said request issued from a requesting IP enabled device;

    determining whether said requested IP packetized content is currently being delivered over said switched digital system; and

    in response to a determination that said requested IP packetized content is not currently being delivered, switching in at least one stream via said switched digital system to effect delivery of said requested IP packetized content; and

    concurrent with said delivery of said requested IP packetized content to said requesting IP enabled device, delivering said legacy non-IP encoded content via said switched digital system to at least one non-IP enabled user device in a same service group as that of said requesting IP enabled device;

    wherein said legacy non-IP encoded content delivered from said content distribution network to said non-IP enabled device and said IP packetized content concurrently delivered from said content distribution network to said requesting IP enabled device are configured to intermix without regard to an encoding thereof in a first IP format and/or a second legacy non-IP format.
