Abstract
Aspects of the subject disclosure may include, for example, a method in which a connection is initiated to an adaptive bit rate (ABR) content delivery network delivering ABR data streams at different bit rates. A manifest associated with the network includes a profile of each data stream and its associated bit rate. The method also includes requesting delivery of content and downloading the content. If the download speed is greater than the delivery bit rate, the manifest is queried for a higher bit rate. If a higher bit rate is not available, a recommendation is received from the content delivery network to obtain additional content via an alternate content stream delivered by a second network. The method further includes selecting the profile for the alternate content stream from the manifest, and receiving the alternate content stream from the second network in accordance with the selecting. Other embodiments are disclosed.
