Abstract:
Disclosed herein are a hybrid download method and apparatus for multiview streaming. The hybrid download method includes requesting a group download for an n−1-th segment from a server, playing an n−3-th segment at a viewpoint VP1 of a viewer, when a group download request for the n−1-th segment is completed, making a group download request for an n-th segment, when a change in a viewpoint of the viewer occurs at a time at which an n−2-th segment is played, playing a low-quality n−2-th segment at a viewpoint VP3, when the group download for the n-th segment is completed, requesting a single download for a high-quality n−1-th segment corresponding to the viewpoint VP3 from the server, and when the single download for the high-quality n−1-th segment corresponding to the viewpoint VP3 is completed, playing the high-quality n−1-th segment at the viewpoint VP3.
