Image processing device and method

A video providing device provides video content comprising a plurality of viewpoints. The device comprising a video storage unit is operable to store a plurality of versions of a video for each of a plurality of viewpoints in the video content, each video corresponding to the same viewpoint being encoded with a different resolution and a different group of pictures duration. A viewpoint determining unit is operable to determine a requested viewpoint in the video content. A video selection unit selects a video from amongst the plurality of versions corresponding to the requested viewpoint, the selected video having a next-occurring group of pictures boundary. A video transmitting unit transmits the selected video to a video receiving device. A video switching unit, if the selected video is not the highest-resolution video corresponding to that viewpoint, performs successive switches to higher-resolution videos at the next-occurring group of pictures boundary in a higher-resolution video until a switch is performed to the highest-resolution video for the determined viewpoint. The video transmitting unit transmits a switched video instead of the selected video. The video may be shown on a head mounted device.
