摘要:
Data is transferred from a host system to a subsystem connected to the host by a system bus in an efficient manner using one or more virtual first in first out (FIFO) registers in host memory and a corresponding set of virtual FIFOs located in the subsystem memory. A transmission controller controls the transfer of data from the host FIFOs to the subsystem FIFOs while the subsystem processor reads and processes data from the subsystem FIFO. By accumulating data in the host FIFOs before transfer to the subsystem, overhead associated with starting and stopping data transfers over the system bus is substantially reduced.

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 (

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.

A method for communicating information for pre-defined metrics management of business metrics uses a system including a server and at least one user accessible device communicative with the server. The server has a database and a web interface. The method comprises providing a user with a web interface configurable to a template accommodating business metrics data by the user, and providing visual indications of the status of the business metrics.
