    摘要: The present invention discloses methods and systems for providing very high quality audio and video playback using all-digital wireless paths from the source to the speaker transducers, video displays and headphones located anywhere within a distance allowed by the FCC. Each speaker has a separate digital amplifier dedicated to each transducer within it (e.g. woofer, tweeter). The present invention also discloses a system that provides a data link capable of sending an all-digital, full-bandwidth, signal from the original digital source material to each separate transducer in the system without using sound degrading lossy data compression. This system is designed to read, broadcast, and reproduce with accurate audio loudspeaker time-alignment (

    摘要: A computer-based digital wireless audio and video system for consumer audio, home theater and recording studio applications is disclosed. The system distributes synchronized 2-channel stereo and multi-channel home theater video and audio digital signals via wireless broadcast to a closed network including a personal computer, a display, and one or multiple digital active loudspeakers or headphones. Each loudspeaker has a separate digital amplifier dedicated to each transducer within it. The system provides a data link capable of sending an all-digital, full-bandwidth signal from the original digital source material to each separate transducer in the system without using sound degrading lossy data compression. This system is designed to read, broadcast, and reproduce with accurate audio and video channel synchronization in the effort to maintain the integrity of the entire audio and video signal.
