First Claim
Patent Images
1. A method of communicating a command to a controllable device, comprising the steps of:
- generating a watermark comprising the command, which is to be executed by the controllable device;
generating a watermarked signal comprising the watermark and an information unit to be transmitted to the controllable device; and
transmitting the watermarked signal to the controllable device for causing the controllable device to execute the command, wherein transmitting the watermarked signal comprises rendering the watermarked signal using at least one of a video device and an audio device, the controllable device capable of receiving the rendered watermarked signal produced by at least one of the video device and the audio device.

Abstract
Disclosed are a method, a controlling device (110), a controllable device (130) and an arrangement (100) for communicating a command from the controlling device (110) to the controllable device (130). A watermark is generated comprising the command, and embedded in a signal (120) representing an audio or video fragment. The controllable device (130) receives the signal (120) comprising the command, and decodes and executes the command therefrom. Also disclosed is a method of presenting an advertisement which involves sending a command related to presenting the advertisement using the above-mentioned method.
