Abstract: A video providing device for providing video content having a plurality of viewpoints, the device including a video storage unit 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 operable to determine a requested viewpoint in the video content, a video selection unit operable to select 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 operable to transmit the selected video to a video receiving device, and a video switching unit operable to, if the selected video is not the highest-resolution video corresponding to that viewpoint, perform successive switches to higher-resolution videos at the next-occurring group of pictures boundary in a higher-resolutio

Abstract: A video providing device for providing video content having a plurality of viewpoints, the device includes: a video storage unit operable to store a plurality of versions of a video for each of a plurality of the viewpoints in the video content, the videos being encoded such that each video includes a region of high resolution corresponding to that viewpoint, where a plurality of the videos each include the same region of high resolution, and each video having the same region of high resolution is encoded with a temporal offset of the group of pictures relative to those other videos with the same region of high resolution, the group of pictures offsets defining video switching times for each video, a viewpoint determining unit operable to determine a requested viewpoint in the video content, a timing identification unit operable to identify a next suitable video switching time from amongst the plurality of video switching times, a video selection unit operable to select a video with a high resolution region c

Abstract: A display system for displaying video content, the display unit including a display controller operable to control the display of at least a region of the video content and a visual acuity identification unit operable to identify at least regions of high visual acuity and low visual acuity of a viewer at display positions corresponding to particular regions of the video content, where the display controller is operable to control the display of video content such that regions of high visual acuity are displayed differently to regions of low visual acuity.

Abstract: A method of adapting content responsive to a well-being of a user wearing a head mountable display (HMD) includes detecting, by one or more sensors, one or more parameters indicating one or more current properties of the user wearing the HMD, generating information indicating the well-being of the user based on the one or more parameters, and adapting an output of the HMD responsive to the generated information, the output comprising at least one of an image and an audio signal.

Abstract: A media recorder is operable to receive broadcast media data from a media data source. The media recorder comprises a storage element for storing at least a portion of the media data, and a receiver for receiving a sequence of video images from a video camera. The media recorder further comprises a user detector for detecting whether a user is attending to a presentation of the media data, and a media presentation status detector operable to detect whether the presentation of the media item has ended. If the user detector detects that the user is not attending to the presentation, the user detector is operable to cause the storage element to store the media data. If the media presentation status detector detects that presentation of the media item has ended, the media presentation status detector is operable to cause the media recorder to enter a stand-by mode.

Abstract: A stereoscopic image processing method for a stereoscopic image pair forming a 3D image comprises the steps of evaluating whether the distance of a user is closer or further than a preferred distance from a 3D image display upon which the stereoscopic image pair is to be displayed, and if the evaluation indicates that the user is further than the preferred distance from the 3D image display, adjusting the respective displacements between corresponding image elements in the stereoscopic image pair, thereby changing the stereoscopic parallax in the 3D image.
