Abstract
Consumer uses of mobile devices and electronic media are changing. Mobile devices include increased computational capabilities, mobile broadband access, better integrated sensors, and higher resolution screens. These enhanced features are driving increased consumption of media such as images, maps, e-books, audio, video, and games. As users become more accustomed to using mobile devices for media, opportunities arise for new digital watermarking usage models. For example, transient media, like images being displayed on screens, can be watermarked to provide a link between mobile devices, extending the reach of digital watermarking. Digital fingerprinting can also be employed. Applications based on these emerging usage models can provide richer user experiences and drive increased media consumption. A great variety of other features and arrangements are also detailed.

1. (canceled)
- 2. A portable device comprising a processor, a memory, an input sensor for capturing data, and an output device, the memory including instructions by which the processor can process the captured data to derive plural-bit data therefrom according to plural different digital watermarking and/or content fingerprinting schemes, the input sensor being selected from the group consisting of a microphone and an image sensor, the memory further including instructions causing the processor to analyze captured data for clues, and based on such clues determine which of said plural different schemes to apply to the captured data.

3. A method practiced in a movie auditorium, comprising the acts:
-
capturing audio or image data from a movie presentation, using a portable device; by reference to the captured data, identifying a particular temporal location within a movie; accessing information in a subtitle repository from the portable device, said accessing making reference to the identified temporal location; and presenting subtitle information on a display screen of said portable device, in synchrony with the movie presentation.
-
-
4. The method 3 that further includes, by reference to the captured data, identifying the movie.
-
5. The method 4 that includes using a processor in the portable device to decode plural-bit data steganographically encoded in the captured data, and identifying the movie by reference to this decoded data.
-
6. The method 3 that includes identifying the particular temporal location by reference to audio or visual landmarks within the movie.
