Abstract: A method for transmitting massive data by using dynamically adjusted updating frequencies is employed in an information processing system. The user device dynamically adjusts a level of the data to be transmitted according to an operating condition of the user, such that the server of the information processing system can use different updating frequencies according to different levels of data to transmit wirelessly the data to the user device. The data the user cares more are transmitted by using a higher frequency, while other data the user cares less would be transmitted by using a lower frequency. Thus, the bandwidth consumption can be decreased while in sending data to the user device. The user device can receive and use massive data from the server for performing required mathematic calculations or statistics at the user device so as to decrease the loading of calculations at the server side.

Abstract: An advertising system comprises an advertising server unit and a set-top box. The advertising server unit is capable of receiving at least one advertisement from at least one external advertiser, and broadcasting at least part of the advertisement to outside in a pushing manner. The set-top box is capable of receiving TV signals from outside (e.g., from TV station or satellite TV) and the advertisement, and combining the advertisement with the TV signals, and then transmitting the combined signals to a display device (e.g., TV) for playing. The set-top box can generate at least one record according to a status of advertisement being watched by users (for example, clicking to watch detailed content of the advertisement or to buy the advertised goods), and then transmit the record back to the advertising server unit. Then, the advertising server unit generates a bill according to the record for charging the advertiser.
