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.
Claims24
A method comprising:
- identifying metadata associated with a plurality of video content items, wherein the metadata indicates:
- that a first video 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 video recording device;
- and
- that a second video content item is to be displayed without using the color-cycled mode;
- and
- based on the metadata:
- causing display of the first video content item using the color-cycled mode.
A system comprising:
- a server;
- and
- a computing device;
- wherein the server is configured to:
- determine an expected video recording device frame capture rate;
- generate, based on determining that a first video content item is associated with a video capture interference mode, video metadata comprising the expected video recording device frame capture rate;
- and
- send the video metadata to the computing device;
- and
- wherein the computing device is configured to:
- convert, based on the expected video recording device frame capture rate, the first video content item into color-cycled content comprising a color cycle rate that is less than the expected video recording device frame capture rate, wherein a time period of a full color cycle at the color cycle rate is longer than a time period between frame captures at the expected video recording device frame capture rate;
- and
- cause display of the color-cycled content.
A method comprising:
- receiving, by a user device and from a server, 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
- a second video content item is to be displayed in a video capture non-interference mode;
- receiving, by the user device, a selection of the first video content item;
- and
- based on the metadata:
- converting, by the user device, the first video content item into color-cycled content, resulting in a failure to complete a full color cycle within the frame capture period;
- and
- causing display of the color-cycled content.
