An event based service provides services and/or products based on an event. Services/products are made available to persons attending an event. Services, products, and/or advertisements can be made available to persons via wireless mobile communications devices. The services/products can be made available to persons attending an event. Services/products can be made available while the event is occurring. Additionally, advertising space is auctioned allowing the ability to bid for advertising space for advertising services/products via the event based service. Individual providers can offer services/products to a group of people at the same location, and at a time that people may be most interested in the services/products. Access to the event based service can be via service provider offered access points. An individual provider's device can act as a server that enables services/products to be purchased. An individual provider's device can act as a network gateway that enables services/products to be purchased.
摘要:
A method for automatically adjusting driving signals of a peripheral device includes accessing identification data of the peripheral device periodically, and determining whether an accessed identification data differs from a connecting device identification code stored in a signal source. If the accessed identification data differs from the connecting device identification code, the method includes updating the connecting device identification code based on the accessed identification data and outputting the driving signals to the peripheral device based on the updated connecting device identification code.

A firmware updating system includes a computer apparatus including a video output interface and a control unit electrically connected to the video output interface for controlling the video output interface to output data corresponding to a new firmware. The firmware updating system further includes a display device having a video input interface for electrically connecting with the video output interface so as to receive the data corresponding to the new firmware transmitted from the video output interface. The display device further includes a first memory and a micro control unit electrically connected to the video output interface and the first memory for processing the data corresponding to the new firmware received by the video input interface and storing the new firmware in the first memory.
摘要:
A method for determining a digital signal of a digital display is provided. An extended display identification data (EDID) of the display is read by a computer via a display data (DDC) bus. Firstly, a predetermined parameter is outputted from the computer via the DDC when a user utilizes the computer to reset the resolution of the display. Then, the predetermined parameter is received and saved by the digital display. A horizontal synchronization signal, a vertical synchronization signal and an analog video signal outputted from the computer are received and saved by the digital display. an actual parameter is calculated by the digital display according to the horizontal synchronization signal and the vertical synchronization signal. Lastly, the digital video signal is determined by the digital display according to the predetermined parameter and the actual parameter.
