Apparatus, a method and a computer program for omnidirectional video

An apparatus comprising

• at least one processor and
• at least one non-transitory memory, said at least one memory stored with code thereon, which when executed by said at least one processor, causes the apparatus to perform at least:
• obtain information of a region for overlaying at least a part of an omnidirectional video, wherein the region for overlaying comprises, at least, a recommended viewport;
• obtain information of a current viewport in the omnidirectional video;
• obtain information of an overlaying method for determining whether to overlay a part of the current viewport by the region for overlaying, wherein the information of the overlaying method comprises at least one condition;
• and
• encode the information of the region for overlaying, the information of the current viewport and the information of the overlaying method, wherein the encoding is configured to enable overlaying of the part of the current viewport by the region for overlaying based on the overlaying method in response to a determination to overlay.

A method comprising:

• receiving information of a region for overlaying at least a part of an omnidirectional video, wherein the region for overlaying comprises, at least, a recommended viewport;
• receiving information of a current viewport in the omnidirectional video;
• receiving information of an overlaying method for determining whether to overlay a part of the current viewport by the region for overlaying, wherein the information of the overlaying method comprises at least one condition;
• decoding the information of the overlaying method;
• decoding image information of the current viewport;
• decoding image information of the region for overlaying;
• examining the decoded information of the overlaying method to determine whether to overlay the part of the current viewport by the region for overlaying;
• and
• overlaying the part of the current viewport by the region for overlaying in response to a determination to overlay the part of the current viewport by the region for overlaying.

• decode image information of the region for overlaying;
• examine the decoded information of the overlaying method to determine whether to overlay the part of the current viewport by the region for overlaying;
• and
• overlay the part of the current viewport by the region for overlaying in response to a determination to overlay the part of the current viewport by the region for overlaying.
