Abstract: In an electronic device for implementing various functions using a DSP, the functionality can be updated as required. The electronic device is provided with a DSP and a flash memory for storing a program executed by the DSP. A program for implementing a new function implements both an old function and the new function, and for implementing a function corresponding to a version flag that has been set in version flags. When the program in the flash memory is updated to a program for implementing the new function, the program for implementing a new function is loaded into the flash memory, and a version flag corresponding to the new function is set in the version flags.

Abstract: The present invention is concerned with an audio equipment capable of processing video signals and a method of displaying operation of the acoustic equipment. An input selector switch 1 is supplied with reproduced audio signals from devices connected to a tuner unit 2 and input terminals 3, and supplies a signal to a sound field processing DSP unit 4. A signal processed by the DSP unit 4 is applied through a muting switch 5 to an output terminal 6. An input selector switch 7 is supplied with reproduced video signals from devices connected to input terminals 8, and supplies a signal to a graphic controller (GDC) 9 which generates a video signal to display an image. One of a signal generated by the GDC 9 and an original video signal are selected by a switch 10, and applied to an output terminal 11. The GDC 9 also generates an image simulating a control panel. When a key switch 13 is operated, the display corresponding to the operated key in the simulating image is varied.

Abstract: An audio signal processing method wherein it is detected whether the data supplied from an optical disk reproduction apparatus or the like has continuous zero data for a predetermined period of time, and in the case where zero data continue for the predetermined period of time, it is determined that compressed audio data is involved, and the supplied data is decoded.

Abstract: The invention relates to a method of transmitting data and the like which are preferably applied to cases where different types or schemes of data are transmitted using a bus line, for example, an IEEE1394 bus line. Data of one sample is transmitted using multiple slots each having a data length of 32 bits. For example, when the data of one sample has 128 bits, data of one sample is transmitted using 8 slots. Each slot includes segmented 16 bits. The leading 8 bits of the 32-bit data constitute label data, with its lowest 3 bits indicating a slot number. Information regarding the number of data bits to be included in one slot is contained in the ancillary data. Data can be easily transmitted if the number of bits in the data of one sample exceeds the maximum bits by which the data can be transmitted using one slot.

Abstract: A sound reproducing system in which virtual image orientation processing of audio signals for at least two rear speakers disposed in directions from a listener close to the right-back direction from the listener is performed by a virtual sound orientation processor so that the listener can have a sound image at a position different from each of real speaker positions at which the rear speakers are placed, and/or so that the listener is unconscious that sounds are radiated from the rear speakers placed at real speaker positions. This virtual image orientation processing is performed according to acoustic transfer coefficients of transfer of sounds from the rear speakers to the listener's ears when the rear speakers are placed at virtual speaker positions different from the real speaker positions.
