1. A method for consumption of omnidirectional visual media content, comprising:
receiving from a sender a bitstream defining a presentation, the presentation comprising an omnidirectional visual media content;
transmitting the presentation to a receiver device;
determining a condition when to send viewport orientation information to the sender, wherein the determining is based on at least a distance relating to a moving viewport and a corresponding threshold;
signaling the determined condition from the sender to the receiver device or from the receiver device to the sender;
when the determined condition is met, generating a packet comprising the viewport orientation information and sending the packet to the sender;
receiving a presentation from the sender to be streamed on the receiver device according to the sent viewport orientation; and
using one or more of (1) a velocity of a rendering device and (2) the distance for the following:
calculating time for the moving viewport to reach a margin boundary; and
determining the condition for the viewport orientation information.
