    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.

    Abstract: Content providers, such as television companies, may multicast adaptive bitrate content, using playlist-oriented streaming techniques, to recipient devices (such as set-top boxes (“STBs”)). In a playlist-oriented streaming technique, segment files (e.g., segments of the content) may correspond to predetermined time segments. In order to mitigate lag time, when a channel is selected by a user of an STB, which may ordinarily be caused by the nature of playlist-oriented streaming techniques, an STB may obtain content, associated with the selected channel, via a unicast, non-playlist-oriented technique. Once the next segment file has been received by the STB, the STB may cease obtaining the content by the unicast technique, and may use the segment files received via multicast.
