摘要： A method, apparatus, and computer program product provide for signaling of viewport orientation timing, such as in panoramic video delivery. In the context of a method, the method receives a first stream comprising panoramic video content based on a first viewport orientation. The method generates a feedback message comprising one or more updated parameters of a second viewport orientation and causes transmission of the feedback message. The method also receives a second stream comprising panoramic video content based on the second viewport orientation of the client device. The method further comprises determining a motion to high-quality delay value based on timestamps associated with the first and second streams and causing transmission of the motion to high-quality delay value.

摘要： A method, apparatus, and computer program product provide for extended margins around a viewport for immersive content. In the context of a method, the method receives panoramic video content and determines at least one motion signal. The method determines a viewport area, margin area, and background area for the panoramic video content based on the at least one motion signal and a quality level for each area. The method causes transmission of a request for updated panoramic video content in accordance with the determined quality levels. The method also receives updated panoramic video content in response to the request and causes rendering of the content for display.

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).
