Integrated audio video signal processing system using centralized processing of signals

摘要

Integrated processing of audio/video signals can eliminate unnecessary signal processors and converters without losing the functionality of typical home entertainment system components. The integrated system includes a main player that captures and processes signals digitally, a dummy display, and a dummy speaker. The dummy display may only have a display panel and a panel driver. The dummy speaker may only have a driving unit and no crossover logic. The main player may have a PC architecture and process all signals digitally for outputting signals tailored for the display device and the individual driving units of the dummy speaker. The integrated system may also provide dynamic signal adjustments based on the surrounding environment. The main player may include a storage device and can process media content stored therein to produce supplemental information to provide an optimal audiovisual experience. This supplemental information can be shared among users over a network connection.

主权项

1. A speaker system, comprising:
a digital crossover unit implemented as a software module and configured to separate an input audio signal into different frequency ranges; a hybrid amplifier configured to respectively receive the different frequency ranges output by the digital crossover unit and to generate a plurality of speaker driving currents corresponding to the different frequency ranges; a first interchangeable speaker module comprising a woofer speaker unit configured to receive a low frequency driving current; and a second interchangeable speaker module comprising a tweeter speaker unit configured to receive a high frequency driving current; wherein: the digital crossover unit and the amplifiers are not contained in any of the speaker units; each speaker unit comprises a dummy speaker comprising a driving unit and no crossover logic; the hybrid amplifier comprises:
at least one digital amplifier providing the low frequency speaker driving current to the woofer speaker unit; andat least one analog amplifier providing the high frequency speaker driving current to the tweeter speaker unit; and the digital crossover unit is configured to dynamically adjust the different frequency ranges while an audio source is playing.
