Abstract: A projection system and a control method thereof are provided. The projection system includes a projector. The projector comprises a projection module and a processor. The processor is electrically coupled to the projection module. The projector confirms whether a first triggering event is detected and turns on a sleep aid mode in response to the first triggering event. The sleep aid mode corresponds to at least one control parameter. In the sleep aid mode, the projection module plays at least one multimedia file according to the at least one control parameter. The processor adjusts at least one parameter value of the at least one control parameter to adjust the at least one multimedia file correspondingly. The projector confirms whether a second triggering event is detected and the projection module stops playing the at least one multimedia file and turns off the sleep aid mode in response to the second triggering event.

Abstract: A method of bandwidth allocation in a Resilient Packet Ring (RPR) network includes: congestion degree of a present node in the RPR network is determined. There is an upstream node and a downstream node of the present node in the RPR network. A present local arrival rate of local traffic flows of the present node from at least one client is obtained. An average transit rate of fairness eligible (FE) flows of the present node in a past time period is calculated. An effective node number for the present node and a present temporal fair rate of the present node are calculated respectively. A present local fair rate of the present node is obtained by looking up a local fair rate table. Transit rate transmitted by the upstream node is controlled according to the present local fair rate of the present node.
