摘要： Techniques for adaptive QoS include selecting, based on one or more QoS criteria corresponding to a client, one or more given data items suitable for sending to the client in response to a query from the client. The one or more given data items are selected from a set of data items. One or more statistics are associated with the one or more data items. The one or more statistics are useable to modify which data items are included in the set of data items. The statistics may be used by removing unpopular data items, as determined by the statistics, from the set of data items in the communication system. Additionally, data items exceeding the one or more QoS criteria can be transcoded to create new data items meeting the one or more QoS criteria, and the new data items can be added to the set of data items in the communication system. Thus, the set of data items can be changed depending on current demand by users for particular data items.

摘要： A driving circuit for a LED backlight module includes a brightness adjusting module, a current detector, a reference voltage adjusting module, and a comparing module. The current detector is capable of detecting the current of the brightness adjusting module and outputting a detecting result. The reference voltage adjusting module is capable of choosing the corresponding reference voltage corresponding to the detecting result of the current detector. Thus, the reference voltage outputted to the comparing module can be adjusted according to the change of the current of the brightness adjusting module. This reduces the power consumption and the amount of heat generated due to the power consumption, and improves the performance of the LED backlight module.

The voltage booster circuits are used for conversing an input voltage into a needed output voltage to supply to an LED unit. The constant current driving IC module is used for controlling the voltage booster circuits, so that the voltage booster circuits converse the input voltage into the needed output voltage to supply to the LED unit, driving the LED unit in a constant current. The constant current driving IC module generates driving signals at different frequencies to control the voltage booster circuits respectively. The invention can set up multiple driving signals operating simultaneously at different frequencies respectively and disperse resulting harmonic wave, hence reduce EMI signals of the backlight driving circuit effectively.
