Abstract

A broadcast stream contains different types of information with the different types identified in the stream. An information processing device receives the broadcast stream and selectively captures (for future playback) only those pieces of information corresponding to one or more preselected types of information. In one embodiment, the broadcast stream is a radio broadcast and the different types are identified in digital sidebands of the radio signals. In other embodiments, the broadcast stream is embedded into audio signals or video signals using luminance or chrominance modulation or other spread spectrum techniques. A user is able to edit a personal profile that is stored in the device and contains the list of preselected types of information. In one embodiment, the device has an interface that allows the user to edit the personal profile, for example, by connecting the device to a personal computer running a profile-editing software program or by communicating with a service bureau that provides the profile-editing function. In this way, each information processing device can be programmed to capture only the subset of information in the broadcast stream in which the user is interested.
