Abstract
Methods and systems described herein generate content that quickly cycles between different-colored frames at a rapid rate that may be imperceptible to human viewers. The human eye tends to blend nearby frames together, so that a human viewer will see a full color spectrum even though only a single color is displayed at any given time. The video display may repeatedly cycle between individual color frames, thus providing video content that appears normal to a human viewer. However, a video recording device may capture only some of the color frames. Therefore, the video recorded by video recording devices may include undesirable color flicker or other color artifacts, which may deter unauthorized copying.
Claims20
A method comprising:
- determining that metadata associated with video content indicates a secure display mode;
- converting the video content into color-cycled content comprising a first plurality of frames of a first primary color, a second plurality of frames of a second primary color, and a third plurality of frames of a third primary color;
- and
- causing display of the color-cycled content.
A system comprising:
- a server configured to:
- determine that first video content is associated with a secure display mode;
- generate video metadata associated with the first video content to indicate the secure display mode;
- and
- transmit the video metadata to a computing device;
- and
- the computing device, wherein the computing device is configured to:
- convert the video content into color-cycled content comprising a first plurality of frames of a first primary color, a second plurality of frames of a second primary color, and a third plurality of frames of a third primary color;
- and
- cause display of the color-cycled content.
A method comprising:
- receiving, by a user device and from a server, metadata indicating that first video content is associated with a secure display mode;
- receiving, by the user device, a selection of the first video content;
- converting, by the user device, the first video content into color-cycled content comprising a first plurality of frames of a first primary color, a second plurality of frames of a second primary color, and a third plurality of frames of a third primary color;
- and
- causing display of the color-cycled content.
