Abstract
A system for adaptive bit rate distribution of multicast streams may include one or more processors and a memory. The one or more processors may be configured to identify streams, such as multicast streams, transmitted by a content delivery network. The streams may each contain a content item that is encoded at a different bit rate for each stream. The one or more processors may determine segments of the streams, for example based on time stamps associated with the content item or markers of the streams. The one or more processors may transmit a first segment of a first stream encoded at a first bit rate to a user device in response to a request therefor and, upon completing the transmission of the first segment, transmit a second segment of a second stream encoded at a second bit rate to the user device in response to a request therefor.
