Abstract

Disclosed is a method that routes all incoming signals from devices (e.g. TV, radio, etc.) to a PC, then distributes the signals to the appropriate devices inside the house. This method is designed for a digital home environment, where the PC becomes the centralized device to control various consumer electronic devices. Benefits include reducing power consumption and the storage space required for received signals.

Efficient Power Use in Entertainment PC Using Selective Listening

Disclosed is a method that routes all incoming signals from devices (e.g. TV, radio, etc.) to a PC, then distributes the signals to the appropriate devices inside the house. This method is designed for a digital home environment, where the PC becomes the centralized device to control various consumer electronic devices. Benefits include reducing power consumption and the storage space required for received signals.

Disclosed is a method that receives all incoming signals from devices (e.g. TV, radio, etc.) and checks for its content before feeding it to a PC for processing and distribution to appropriate devices. If the incoming signal is not of interest to users like commercials, loss of signal etc...then the system intelligently skips the signal and putting the system in to low power state there by saving the system power and storage space required. This method can be directly adopted in the digital home environment.

General Description

The disclosed method checks the incoming signal from cable networks for selected channels or frequencies. If the content is not of interest (e.g. commercials, signal loss due to power failure at satellite receiver in cable office, etc.) then the whole PC system can be put into a low power state automatically, reducing power consumption. The system which was put into a low power state is brought back automatically once normal programming resumes (i.e. after the commercial ends or signal starts coming in after the link failure).

 

The system can be configured to check the content received through a TV tuner. After converting the signal into a digital state, the content check module (i.e. a proposed new module in the PC that works with various other modules, like TV tuners) checks it to make sure it is not the commercial beginning, or a loss of signal, etc. If not, then the program continues normally and the content check module continues to check received signals for commercials or signal losses.

At the start of a commercial, the content check module alerts the user (e.g. a beep or a message display) that the content being received is unrelated to the current program. The user can switch to any another channel and the same logic...
