Techniques for improved multicast content delivery are described. In some embodiments, for example, an apparatus includes a processor circuit, a communication component operative by the processor circuit to receive a data transmission containing a description segment and a correspondence segment, a correspondence processing component operative by the processor circuit to determine a plurality of multicast content streams representing different versions of a media content based on the correspondence segment, and a selection component operative by the processor circuit to select and receive one or more of the plurality of multicast content streams based on characteristics identified in the description segment. In various such embodiments, the apparatus includes an adaptation component operative by the processor circuit to adaptively switch across the plurality of multicast content streams for reception and processing based on characteristics identified in the description segment. Other embodiments are described and claimed.
