Claim Text:
1. A method of supporting seamless transmission of a particular piece of content to a mobile device that travels from a first access network to a second access network while the content is being transmitted, wherein the particular piece of content is being simultaneously transmitted over the first access network to a first multicast group according to a first codec and over the second access network to a second multicast group according to a second codec, the method comprising: transmitting instructions to the mobile device that allow the mobile device to seamlessly access the content as the mobile device travels from the first access network to the second access network, wherein the instructions instruct the mobile device to locate the second multicast group assigned to the content and to process the content for output according to requirements of the second codec once the mobile device is no longer accessing the content over the first network; monitoring progress of the content while being transmitted over the second access network to determine at least one portion of the content not already transmitted to the mobile as important content and at least one portion of the content not already transmitted to the mobile device as less or non-important content; and generating the instructions to specify a transition period when the mobile device is to switch from the first multicast group to the second multicast group in order to begin accessing the content through the second access network, including selecting the transition period to occur while the less or non-important content is being transmitted to the second multicast group such that the mobile device misses at least a part of the less or non-important content transmitted during the transition period.
