Abstract
An exemplary data router may receive from a client device a request to access a multicast packet stream corresponding to a media content channel. The data router may access the multicast packet stream, which may include a plurality of bit rate profiles each including a plurality of data packets representing a component of the media content channel transferred at a particular bit rate. The data router may filter out data packets included within bit rate profiles that have data transferred at a bit rate that is not a preferred or requested bit rate by the client device. The data router may also replace a multicast destination address with a device destination address in the data packets that are not filtered out. The data router may then route the modified multicast packet stream to the client device at the device destination address. Corresponding systems and methods are also described.
