    摘要: This invention concerns a distributed stereo audio system. Distributed stereo audio systems are used to provide stereo sound to several rooms or areas from a single source of signal. The system includes two or more speakers for the broadcast of stereo audio signals; a source of stereo audio signals; a stereo amplifier to amplify stereo audio signals and drive the speakers; and a mains operated electrical power supply to provide power to the amplifier. The amplifier is located in the same room as the speakers, and remote from the signal source and power supply. The amplifier is connected to the signal source and power supply by means of a category 5 four pair twisted cable which provides, in respective twisted pairs, right channel audio signals from the signal source to the amplifier, left channel audio from the signal source to the amplifier, DC power from the power supply to the amplifier, and control signals from the amplifier to the signal source.

    摘要: This invention concerns a distributed stereo audio system (1). Distributed stereo audio systems are used to provide stereo sound to several rooms or areas from a single source of signal. The system includes two or more speakers (2, 3) for the broadcast of stereo audio signals; a source of stereo audio signals; a stereo amplifier (4) to amplify stereo audio signals and drive the speakers; and a mains operated electrical power supply (10) to provide power to the amplifier. The amplifier is located in the same room as the speakers, and remote from the signal source and power supply. The amplifier is connected to the signal source and power supply by means of a category 5 four pair twisted cable (11) which provides, in respective twisted pairs, right channel audio signals (12) from the signal source to the amplifier, left channel audio (13) from the signal source to the amplifier, DC power (14) from the power supply to the amplifier, and control signals (20) from the amplifier to the signal source.

    摘要: A user can have media files associated with a user account in a shared resource environment, enabling the user to access those files from multiple devices and locations. Instead of uploading each file, a process can scan the files to determine corresponding copies already stored to the shared resource environment, which can be associated with the user account without uploading another copy. In cases where encryption or other protection prevents the content of a file from being verified, a fingerprint of unencrypted records of the file can be generated and compared against an index of fingerprints for previously encountered files. If the fingerprint matches information stored for a media file, and the fingerprint meets at least one validity criterion, a copy of the media file can be associated with the user account even though the user's copy cannot be read, or potentially even played, by a component of the environment.

    摘要: A distributed stereo system includes two (or more) speakers; a source of audio signals; an amplifier in the same room as the speakers that drives the speakers; and a mains-operated electrical power supply to power the amplifier. The amplifier is remote from the signal source and power supply and is connected to the signal source and power supply by means of a category 5, four-pair twisted cable or similar, which provides right and left channel audio signals from the signal source to the amplifier and DC power from the power supply to the amplifier. A distributed intercom system features a bi-directional intercom hub; a mains-operated power supply; and two or more remote modules each having an amplifier and speaker. The modules are connected to the hub via category 5 cable or similar, which carries audio signals between the hub and the modules and power from the supply to the modules.
