Abstract: The present invention details a low cost novel apparatus and method of coordinated broadcasting of music among connected peer listeners in a wireless ad-hoc networking environment. One or more receiver/listeners and one or more broadcasting/listeners equipped with a portable music player in local proximity, can use short-range wireless transmission to participate and listen to the same song at the same time. Moreover, the present invention allows listeners in the transmission range to discover broadcasters through channel switching and profile matching. As one broadcaster can have many listeners, channel switching and profile matching are used by the listeners to identify capable broadcasters and by broadcast/listeners to change transmission channels.

Abstract: The present invention provides a method for recording a watermark pattern on a color recording medium that forms an image using a number N of colorants, the method comprising the step of forming the watermark pattern using at least two colorants, but fewer than N colorants.

Abstract: A method is provided for applying a watermark pattern along a length of photosensitive medium, the photosensitive medium having a frame pitch in the length direction that is the sum of an image frame height plus an interframe distance. The method exposes watermark tiles contiguously along the length of the photosensitive medium, wherein each watermark tile has a height dimension that is an integral divisor of the frame pitch.
