Claim 3:
4. A method of supporting continuous access to content when access to the content is transitioned from a first network at a first codec to a second network at a second codec different from the first codec, the method comprising:
identifying whether the content being accessed over the first network is also available over the second network;
if the content is also available over the second network, identifying whether the content is available over a broadcast or multicast tier of the second network;
if the content is available over the broadcast tier, generating transition instructions dependent on a static channel map used by the broadcast tier to instruct access to the content on the second network; and
if the content is available over the multicast tier, generating transition instructions dependent on a current multicast group used by the multicast tier to instruct access to the content on the second network,
wherein the transition instructions comprise parameters of the second codec of the second network and at least one multicast address of the second network, and
wherein the first network is heterogeneous with respect to the second network.
