Abstract
A method for providing privacy during delivery of ABR media content to a plurality of ABR OTT client devices includes receiving, at a network node that includes a Controlled Cache, an ABR manifest for an ABR media asset. The ABR manifest includes a segmentation-units index. Responsive to receiving a request for the ABR media asset from an ABR OTT client device, the method sends to the ABR OTT client device a custom manifest having a number of segmentation-units in segments that is customized for an ABR playback session. A network node, which can be one of an origin server, an edge server and a Just-In-Time Packager (JIT-P), and a computer program product for providing privacy during delivery are also shown.
