摘要：
The embodiments relate to a method and a technical equipment for implementing the method. The method comprises receiving encoded omnidirectional video content for displaying, wherein the encoded omnidirectional video content comprises a viewport region, a margin region outside the viewport region and a background region (801); defining image regions to be included in the margin region, wherein the definition is based on a margin speed threshold (802); determining a head speed and a direction of motion (803); determining when the head speed is greater than or equal to the margin speed threshold, and as a response to the determining, adding negative margins in one or more direction with respect to the viewport (804); downloading the viewport with a first quality; and downloading the negative margins at a quality lower than the first quality (805).
