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.
Claims50
A method comprising:
- identifying, by a computing device, metadata indicating that a first content item is to be displayed using a color-cycled mode in which at least one primary color, of a plurality of primary colors, is omitted from a frame captured by a recording device;
- and
- based on the metadata, causing display of the first content item using the color-cycled mode.
An apparatus comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the apparatus to:
- identify metadata indicating that a first content item is to be displayed using a color-cycled mode in which at least one primary color, of a plurality of primary colors, is omitted from a frame captured by a recording device;
- and
- based on the metadata, cause display of the first content item using the color-cycled mode.
A method comprising:
- receiving, by a user device, metadata indicating that a first video content item is to be displayed in a video capture interference mode in which a time period to cycle between frames of a primary color is longer than a frame capture period of a video recording device;
- converting, by the user device and based on the metadata, the first video content item into color-cycled content in which a full color cycle is not completed within the frame capture period;
- and
- causing display of the color-cycled content.
A system comprising:
- a server;
- and
- a computing device;
- wherein the server is configured to:
- send metadata indicating that a first video content item is to be displayed in a video capture interference mode in which a time period to cycle between frames of a primary color is longer than a frame capture period of a video recording device;
- and
- wherein the computing device is configured to:
- receive the metadata;
- convert, based on the metadata, the first video content item into color-cycled content in which a full color cycle is not completed within the frame capture period;
- and
- cause display of the color-cycled content.
