• and
• at least one non-transitory memory including computer program code,
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least:
• determine a foreground area covering a viewport of 360-degree video, and one or more other areas of the 360-degree video not containing the foreground area in its entirety;
• select a first set of tile streams among available tile streams of the 360-degree video, wherein the first set of tile streams covers the foreground area;
• select a second set of tile streams among the available tile streams of the 360-degree video, wherein the second set of tile streams covers the one or more other areas;
• and
• request transmission of a first set of portions of the first set of tile streams and a second set of portions of the second set of tile streams, wherein at least one of the first set of portions have a shorter duration than at least one portion of the second set of portions.

A computer program product comprising a non-transitory computer readable medium encoded with computer program code configured to, when executed on at least one processor, cause an apparatus or a system to:

• determine a foreground area covering a viewport of 360-degree video, and one or more other areas of the 360-degree video not containing the foreground area in its entirety;
• select a first set of tile streams among available tile streams of the 360-degree video, wherein the first set of tile streams covers the foreground area;
• select a second set of tile streams among the available tile streams of the 360-degree video, wherein the second set of tile streams covers the one or more other areas;
