Abstract
Methods and apparatus for embedding and recovering an image for use with video content are disclosed. A disclosed system embeds a real component of a spectral representation of an image into a set of video frames and embeds an imaginary component of the spectral representation of the image into a second set of video frames. The two sets of video frames are combined and broadcast. The disclosed system recovers the real component of the spectral representation of an embedded image from a first set of received video frames and the imaginary component of the spectral representation of an embedded image from a second set of the received video frames.

A method of embedding image data within a plurality of video frames, comprising:
- embedding a real component of a spectral representation of the image data into a first set of video frames from the plurality of video frames to form a modified first set of video frames;
- and
- embedding an imaginary component of the spectral representation of the image data into a second set of video frames from the plurality of video frames to form a modified second set of video frames.
A method of recovering image data from a plurality of video frames comprising:
- recovering a real component of a spectral representation of the image data from a first set of video frames from the plurality of video frames;
- recovering an imaginary component of the spectral representation of the image data from a second set of video frames from the plurality of video frames;
- and
- recovering the image data based on the real component of the spectral representation of the image data and the imaginary component of the spectral representation of the image data.
A system for embedding image data within a plurality of video frames comprising:
- a processor system including a memory;
- and
- instructions stored in the memory that enable the processor system to:
- embed a real component of a spectral representation of the image data into a first set of video frames from the plurality of video frames;
- and
- embed an imaginary component of the spectral representation of the image data into a second set of video frames from the plurality of video frames.
A system to recover image data from a plurality of video frames comprising:
- a processor system including a memory;
- and
- instructions stored in the memory that enable the processor system to:
- recover a real component of a spectral representation of the image data from a first set of video frames from the plurality of video frames;
- recover an imaginary component of the spectral representation of the image data from a second set of video frames from the plurality of video frames;
