Apparatus and methods for selective secondary content insertion in a digital network

Apparatus and methods for generating secondary content scheduling and dynamic insertion for users of a managed content distribution network, such as a cable, satellite, of HFCu network. In one embodiment, the secondary content comprises advertising content which is directly related or tied to demographics, psychographics, and/or other metrics of applicability to one or more users of the content distribution network. Individual insertion opportunities are identified (either in advance or dynamically), and relevant or targeted secondary content is dynamically "switched in" for delivery to the one or more users via interaction between a local or client application (e.g., operative on the user's set top box or personal electronic device) and a switched digital video entity of the network, and subsequently switched out if no longer required, thereby conserving network bandwidth and/or other resources.
