A method of controlling a display device outputting an image in either one of display modes including a horizontal mode and a vertical mode, the display device including a display configured to be rotatable, includes displaying at least one user interface (UI) element corresponding to at least one image content. The method further includes based on a user instruction of positioning a highlight on a first UI element among the displayed at least one UI element, identifying whether a resolution of a first image content corresponding to the first UI element corresponds to a current display mode, and based on the resolution of the first image content being identified to not correspond to the current display mode, providing a visual effect to the first UI element.

Scenes in video images are identified based on image content of the video images. Regional cross sections of the video images are determined based on the scenes in the video images. Image portions of the video images in the regional cross sections are encoded into multiple video sub-streams at multiple different spatiotemporal resolutions. An overall video stream that includes the multiple video sub-streams is transmitted to a streaming client device.

One embodiment of the present invention sets forth a technique for dynamically cropping image data transmitted to an endpoint device. The technique includes computing a first visual interest score for a first visual interest region within a digital image based on content included in the first visual interest region, computing a second visual interest score for a second visual interest region within the digital image based on content included in the second visual interest region, and determining that the first visual interest region is preferred over the second visual interest region based on the first visual interest score and the second visual interest score. The technique further includes setting a location within the first visual interest region as a point of visual interest and transmitting the digital image and the location of the point of visual interest to a computing device for displaying a portion of the digital image that includes the point of visual interest.

Provided is a method of displaying an image in a display device, the method including transmitting, to a content providing device, image request information requesting the content providing device to selectively transmit an image of a first resolution or an image of a second resolution; receiving the image of the first resolution or the image of the second resolution which is obtained by performing upscaling on the image of the first resolution using a first upscaler, based on the image request information; based on receiving the image of the first resolution, performing upscaling on the image of the first resolution using a second upscaler of the display device to obtain a upscaled image having the second resolution and displaying the upscaled image having the second resolution, upscaling capability of the second upscaler being different from upscaling capability of the first upscaler; and based on receiving the image of the second resolution, displaying the image of the second resolution.

A camera system captures an image in a source aspect ratio and applies a transformation to the input image to scale and warp the input image to generate an output image having a target aspect ratio different than the source aspect ratio. The output image has the same field of view as the input image, maintains image resolution, and limits distortion to levels that do not substantially affect the viewing experience. In one embodiment, the output image is non-linearly warped relative to the input image such that a distortion in the output image relative to the input image is greater in a corner region of the output image than a center region of the output image.

A video display system generally includes a computerized media processing unit configured to receive a plurality of content from a plurality of content sources and configured to combine the plurality of content from the plurality of content sources to generate and output a video signal receivable by at least one display device. The video signal includes an interactive multilayer stream, with a plurality of video layers all displayable on the at least one display device simultaneously with independently variable size and position under the control of a user. The content of one of the video layers may be determined based on the content of a different video layer.

The present disclosure provides systems and methods for video content security and for detecting and preventing unauthorized playback. According to an exemplary method, a device performing a video playback can acquire a set of video frames from a decoder during the video playback, and generate, based on the set of video frames, a first video identifier. The first video identifier can be sent to a server. In response to the server determining that the first video identifier matches a second video identifier stored in the server, the device can receive a list of authorized playback sources associated with the second video identifier. The device can determine whether a source of the video playback is included in the list of authorized playback sources, and control the video playback based on the determination.

Scenes in video images are identified based on image content of the video images. Regional cross sections of the video images are determined based on the scenes in the video images. Image portions of the video images in the regional cross sections are encoded into multiple video sub-streams at multiple different spatiotemporal resolutions. An overall video stream that includes the multiple video sub-streams is transmitted to a streaming client device.

A method causes a display device to display a video depicting an item in a scene and a tag in a first position on a first frame of the video. The tag is associated with the item depicted in the video, and the tag includes text information associated with the item depicted in the video. The method causes the video display to display the tag in a second position on a second frame of the video and causes the video display to display the tag in intermediate positions between the first and second positions during frames between the first and second frames of the video.
