Abstract
There are disclosed various methods, apparatuses and computer program products for adaptive bitrate control for tiled omnidirectional video. In some embodiments information of a size of a viewport to view omnidirectional video data is received and an orientation of a viewport within the omnidirectional video data is determined. A first set of tiles belonging to the viewport and a second set of tiles outside the viewport are determined. A bitrate is estimated for a full picture using a first quality for the first set, and a second quality for the second set. The determination is repeated for a plurality of viewports. A representative viewport orientation is selected using the estimation results. A plurality of bitrates are estimated for a full picture for the third set of tiles and for the fourth set of tiles; and estimated bitrates and the representative viewport orientation are provided to an adaptive bitrate algorithm.
