A portable device, such as a cell phone, is used to “forage” media content from a user's environment. For example, it may listen to a television viewed by a traveler in an airport lounge. By reference to digital watermark or fingerprint data extracted from the content, the device can identify the television program, and enable a variety of actions. For example, the device may instruct a DVR to record the remainder of the television program—or add the program to the traveler's viewing queue (e.g., at Netflix). The device may also identify content that preceded (or follows) the foraged content. Thus, a user who tunes-in just at the end of an exciting sporting event can capture one of the following commercials, identify the preceding program, and download same for later viewing. A great variety of other functions and arrangements are also detailed.
