Abstract

Portable consumer electronic devices featuring image- or audio-capture capabilities, such as cell phones, wristwatches, digital cameras, personal digital assistants, and MP3 players, are becoming increasingly prevalent. Watermark information embedded in the captured content can be used to trigger distribution of corresponding content (web pages, high fidelity audio, etc.) from on-line repositories. Thus for example, music 'heard' by a user's cell phone microphone (10) can be processed and used to trigger the electronic delivery of a high fidelity version (20) of the same (or different) music to the portable device (22) or to the user's home computer (22). Likewise, an object 'shown' to a cell phone camera (10) can initiate a link to a corresponding web page, launch a corresponding application program, or otherwise control the device. The watermark can be decoded from the content in the consumer device, or the content can be transferred to a remote device (14) for decoding.
