Abstract: In structure of selected category of broadcast signals, one channel includes the category of program material transmitted by the station. When the signals having this category designation are applied to the receiver unit, the receiver unit can identify these program categories and, using parameters designated for each category of program material, can process the program material thereby providing an output signal customized for the program material currently being received by the radio receiver.

Abstract: In a dual-channel HD radio receiver, when the broadband filter channel is compromised, the broadband channel is inactivated and the narrowband channel is activated. By mixing the signals of the two channels during the change, undesirable audio artifacts can be minimized.

Abstract: In digital radio technology, information channels describing the properties of the associated performance channel(s) are included in the broadcast band. The digital radio determines when selected signal groups are present in the information channels. Upon identification of a selected signal group, the digital radio automatically reconfigures itself into a user-determined configuration for processing the performance channel. By way of specific example, the user can determine that the equalization of the performance channel for selected musical formats and/or selected artists.

Abstract: In order to accommodate increased processing requirements as additional functionality is added to the digital radio, an audio postprocessor unit is coupled to the output of the demodulation/processing unit. In this manner, the processing capability of the digital radio can be enhanced with relatively minor changes in the hardware and software.

Abstract: In order to enhance the performance of audio presentation of a digital radio, the digital radio presentation is analyzed to extract the parameters of at least one selected instruments. The selected instrument parameters, for example, pitch, intensity, etc., are then reformatted in the form of control signals. The control signals are applied to an automatic (electrically driven) version of the selected instrument. The performance of the selected automatic instrument is played in synchronism with the audio presentation. The present of an actual instrument playing in synchronism with the audio presentation from the speakers driven by the digital radio provides an augmented listening experience.

Abstract: In a digital camera having a rotatable image display, when the camera is placed in an auto-exposure mode, the rotatable image display is positioned to face toward the exposure subjects. In the auto-exposure mode and after the exposure switch is activated, the image display provides a periodic count-down sequence such that an imminent shutter release is identified for the exposure subjects.

Abstract: In a digital camera in a first embodiment, components are added such that when the user operates the switch to acquire an image, the camera provides the external sounds and activity simulating the acquisition of an image, but without actually acquiring a image. The activation of the switch initiates operation of a timing unit. The actual image acquisition is acquired without user input after a preselected time determined by the timing unit. In the second embodiment, activation of a timing unit by switch causes the digital camera to acquire images periodically. The images are transferred to a processing unit where a pattern recognition program examines the acquired image for a preselected feature, such as smile on a face of a subject. When the preselected feature is identified, the digital camera stores the image providing the preselected feature. This invention can be used in the photographing of children.
