Abstract
Rectilinear viewport extraction from a region of a wide field of view is described using messaging in the video transmission field. Some embodiments pertain to a method that includes receiving a wide field of view video, receiving position data from a remote coupled user device, selecting a region of interest in the video based on the received position data, extracting the region of interest from the video, generating region metadata describing the extracted region of interest, encoding the extracted region of interest of the video, and transmitting the encoded video with the region metadata to the user device.
Claims25
A computer-implemented method of image processing, comprising:
- receiving, at a client device, only a region of interest of an entire wide field of view frame of a video and associated with position data transmitted from the client device, wherein multiple possible viewport locations are within the region of interest;
- receiving, at the client device, a description of the region of interest;
- generating updated position data at the client device;
- and
- generating a viewport within the region of interest at the client device using the updated position data.
A computer-implemented method of image processing, comprising:
- transmitting, to a client device, only a region of interest of an entire wide field of view frame of a video and associated with position data transmitted from the client device, wherein multiple possible viewport locations at the client device are within the region of interest;
- and
- transmitting, to the client device, a description of the region of interest to generate a viewport within the region of interest at the client device using position data updated by the client device.
A head mounted display (HMD), comprising:
- at least one display means to be viewed by a user wearing the head mounted display (HMD);
- means for transmitting position data of at least a position of the HMD;
- means for receiving only a region of interest of a video rather than an entire wide field of view frame of the video and associated with the position data;
- means for receiving a description of the region of interest and that corresponds to multiple possible viewport locations within the region of interest;
- means for generating updated position data of the head mounted display;
- and
- means for generating a viewport within the region of interest by using the updated position data.
