摘要:
Methods, apparatus and computer program products reduce bandwidth requirements in mobile video and gaming applications by tracking a gaze fixation point of a user on a video image at a remote location; generating information identifying the gaze fixation point at the remote location; transmitting the gaze fixation point information to a source of video information over a network; determining a portion of a video image to transmit at a high resolution and a remaining portion to transmit at a low resolution using the transmitted gaze fixation point information; and transmitting the portion of the video image selected for transmission at a high resolution at the high resolution and the portion of the video image selected for transmission at a low resolution at the low resolution. Further methods, apparatus and computer program product also reduce bandwidth requirements by receiving gaze fixation point information from a remote location, wherein the gaze fixation point information indicates where in a video image a user is currently looking; selecting a portion of video images to transmit at a high resolution and a portion of video images to transmit at a low resolution using the transmitted gaze fixation point information; and transmitting the portions of the video images at the determined resolutions.
