A method for processing audio/video signals. The method includes determining if the video signals are in two dimensional or three dimensional format. If the video signals are in two dimensional format, the method includes providing a first delay to be applied to the audio signals. If the video signals are in three dimensional format, the method includes providing a second delay, longer than the first delay, to be applied to the audio signals.

Audio synchronization for two dimensional and three dimensional video signals

A method includes providing, to a user of a control device, an indication of a value currently representative of a preset sound signal source, and simultaneously providing an indication of a possible new value of the preset.

Remote controlling

A method and apparatus for processing multi-channel audio signals in which the channels are processed by one of alternatively selectable processes to produce an alternatively selectable number of output channels, the process being responsive to information contained in the input signal.

Audio signal processing

An audio system may include a plurality of sound reproduction devices characterized by parameter values; a plurality of audio signal sources characterized by parameter values; a plurality of remote control devices, a system controller, constructed and arranged to wirelessly receive command signals from the remote control devices and to wirelessly transmit parameter values of audio signal sources and of sound reproduction sources to the remote control device. The remote control devices are constructed and arranged for wirelessly transmitting command signals to the system controller and for wirelessly receiving parameter values and displaying parameter values. The remote control devices are being further constructed and arranged to transmit command signals to and receive parameter values from a system controller that is separated from remote control. A remote control for use with the audio system illuminates only graphic figures corresponding to terminals to which a sound reproduction device is attached; illuminates graphic figures corresponding to surround speakers only if a selected sound reproduction device is equipped for surround speakers; and has a touch screen which can be disabled. An audio system has volume adjusting circuitry which allows collective volume adjusting of different devices while maintaining a volume offset, and has circuitry which allows collective turning on and off of sound reproduction devices receiving signals from the same signal source.

Transceiving remote controlling

A radio receiver has a radio tuner having a radio frequency input and an audio output, and an audio signal amplifying system having an audio input and an electroacoustical transducing output. A volume controller is coupled to the radio tuner and the audio amplifying system. A microprocessor is coupled to the tuner, volume controller, a visible display and an array of controls. The microprocessor is constructed and arranged to respond to actuation of the controls to cause the tuner to be tuned to a selected radio frequency, cause the display to display the frequency to which said radio tuner is tuned, cause the volume controller to set the sound level from the electroacoustical transducing output and cause the display to display a quantity representative of the volume to which the volume controller is then set and further constructed and arranged to respond to actuation of the controls to selectively couple the radio tuner audio output to the audio input while initially setting the sound level to zero when the signal on the audio output coupled to the audio input begins and gradually increasing the sound level to a predetermined value and reducing the sound level to zero when the signal on the audio output then coupled to the audio input ends.
