Abstract

Integrated processing of multimedia 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 generate parameters for optimizing display of a video source. These parameters can be shared among users over a network connection.

Claims

1. An integrated multimedia processing system, comprising:

a video source providing a video signal;

a central processing unit adapted to be responsive to the video signal from the video source to generate a digital display signal; and

a dummy display driven directly by the digital display signal to display video output, wherein the central processing unit controls the video signal.

2. The integrated multimedia processing system comprising:

a media source;

a central processing unit; and

a digital processing module that processes a signal coming from the media source.
