A method comprising: receiving (11.1) a first video data representing a three-dimensional video content arranged as a plurality of first tiles associated with respective sub-areas of an image; providing (11.2) data indicating for each first tile a depth range of the three-dimensional video content within said tile; determining (11.3) for the each first tile a respective volume based on the depth range; determining (11.4), based at least in part on position and orientation of a display device, a field of view of a user in relation to the first tile volumes; rendering (11.5) of the first video data for one or more first tiles of the plurality of first tiles as one or more screen tiles comprising respective pixels or groups of pixels for display on the display device, if a determined volume of the one or more first tiles is at least partially within the field of view; identifying (12.1) one or more of the screen tiles having invalid pixel data, wherein invalid pixel data relates to pixel positions within the one or more screen tiles which have no graphical data; receiving (12.2) a second video data representing the three-dimensional video content captured from a different location than the first video data, the second video data being arranged as one or more second tiles; identifying (12.3) one or more second tiles that, when projected onto the screen tiles from the different location, correspond to at least one of the identified one or more screen tiles having invalid pixel data; and rendering (12.4) pixel data of the identified one or more second tiles to fill-in the at least one of the screen tiles having invalid pixel data. receiving (11.1) a first video data representing a three-dimensional video content arranged as a plurality of first tiles associated with respective sub-areas of an image; providing (11.2) data indicating for each first tile a depth range of the three-dimensional video content within said tile; determining (11.3) for the each first tile a respective volume based on the depth range; determining (11.4), based at least in part on position and orientation of a display device, a field of view of a user in relation to the first tile volumes; rendering (11.5) of the first video data for one or more first tiles of the plurality of first tiles as one or more screen tiles comprising respective pixels or groups of pixels for display on the display device, if a determined volume of the one or more first tiles is at least partially within the field of view; identifying (12.1) one or more of the screen tiles having invalid pixel data, wherein invalid pixel data relates to pixel positions within the one or more screen tiles which have no graphical data; receiving (12.2) a second video data representing the three-dimensional video content captured from a different location than the first video data, the second video data being arranged as one or more second tiles; identifying (12.3) one or more second tiles that, when projected onto the screen tiles from the different location, correspond to at least one of the identified one or more screen tiles having invalid pixel data; and rendering (12.4) pixel data of the identified one or more second tiles to fill-in the at least one of the screen tiles having invalid pixel data.
