Embodiment Construction

[0053]In an embodiment of the invention, the embedding aspect has application in relation to projecting digital movies in cinemas. According to the invention, in one embodiment, a digital cinema projector either comprises or is connected to a watermark embedder according to the invention and embeds a watermark during projection of a film. Typically, information such as the projector's serial number and time code is embedded as payload.

[0054] figure 1 Represents an embodiment of a watermark embedding scheme module diagram, namely figure 1 A watermark embedder according to the invention is shown. Embedding schemes facilitate embedding payloads in moving image signals comprising sequences of images or frames. Payloads are usually in the form of multi-bit payloads. The payload is embedded into the image signal by embedding a reference watermark and a shift watermark, the shift representing the payload. The shift may be a periodic rotation of the watermark along the time ax...

Abstract

The invention relates to embedding in, as well as to extracting a payload from a motion image signal. Furthermore, the invention relates to a motion image signal. A payload is embedded in the motion image signal by the following steps. A first and an at least second watermark are represented by at least a first sequence of watermark samples, and a first and at least a second global property of an image of the signal are determined. Subsequently, the first and the at least second watermark are embedded in the signal, so that a shift of the at least second watermark with respect to the first watermark represents the payload. The first and the at least second watermarks are embedded by modifying the first and the at least second global property in the image in accordance with the corresponding watermark samples. The first and second global properties may be the mean luminance and the mean color saturation of the pixels constituting the image.

Description

technical field [0001] The present invention relates to a method of embedding and extracting payloads in moving image signals. The invention also relates to a watermark embedder, a watermark detector, a moving image signal, a storage medium and a computer readable code. Background technique [0002] Watermark embedding is an important aspect of copyright protection strategy. While most copyright protection schemes deal with the protection of electronically transmitted content (broadcasting, storage media), movies shown in theaters also require copyright protection. Illegal copying in movie theaters using hand-held camcorders is already a common practice. Despite their often low quality, the economic impact of illegal VHS tapes, discs and DVD titles is significant. [0003] The Digital Cinema Project's video watermarking scheme is designed to work with upcoming digital cinema formats and to help content owners and distributors trace the source of illegal copies. Watermark...
