  • Patent number: 7243168
    Abstract: A computer subsystem of a computer includes a CPU, RAM, display, storage device, input device(s), and a digital-audio generating IC. A CD-ROM subsystem of the computer includes a CD-ROM drive and CD-ROM control buttons for controlling CD-ROM drivers operation while playing audio CDs. An audio-interface IC of the CD-ROM subsystem couples a bus of the computer subsystem to the CD-ROM drive, and to the control buttons. The audio-interface IC, in one operating mode, relays commands and data between the bus and the CD-ROM drive. A second operating mode permits turning the computer subsystem off while the audio-interface IC autonomously responds to the control buttons and transmits commands to the CD-ROM drive for playing an audio CD.

  • Publication number: 20060101175
    Abstract: An audio controller for use with laptop and notebook digital computers for reproducing compressed digital audio recordings. The controller includes a drive interface for traversing and accessing audio data files stored on a drive of a computer system. Function keys coupled to the controller permit users to access drives containing desired audio data. The selected audio data is read from the drive into the controller. Decoding circuitry decodes the audio data and generates a decoded audio data stream. The data stream can be converted to an analog signal by the controller, or sent to the audio subsystem of the computer system. Advantageously, the controller operates when the computer system is in an inactive state, for example in power saving mode or OFF, and operates in passthrough mode when the computer system is ON or active.

  • Publication number: 20060080475
    Abstract: A controller for use with laptop and notebook digital computers for reproducing compressed digital audio and video files. The controller includes a drive interface for traversing and accessing data stored on a drive of a computer system. Function keys or a remote controller permit users to access drives containing desired data. The selected data is read from the drive. A decoder circuit parses the data into audio data and video data and decodes each set of data to generate a decoded audio data stream or video data stream. The audio data stream can be converted to an analog signal by the controller, or sent to an external ADC of the computer system. Advantageously, the controller operates when the computer system is in an inactive state, for example in power saving mode or OFF, and operates in passthrough or bypass mode when the computer system is ON or active.
