Abstract

A method, device and computer program for providing privacy during delivery of ABR media content to an ABR OTT client device are shown. The method receives an ABR manifest for an ABR media asset; the ABR manifest includes a segmentation-units index that points to segmentation-units in the ABR media asset. Using the segmentation-units index and a customization process, randomized byte-range requests for portions of the ABR media asset are produced and sent. Responsive to receiving the randomized byte-ranges, the ABR media asset is reassembled in order and provided to a media player in the client device.
