Abstract: PURPOSE: A method for displaying the operation of a video system in real time is provided to detect the operation time of the video system in real time to display the total accumulated operation time. CONSTITUTION: A power supply provides power to a microcomputer(201). The microcomputer is operated by the power and, when an operation on signal is provided by a remote control, drives a timer. The timer is driven by a timer driving signal provided by the microcomputer(203-1). The microcomputer reads the actual operation time of a video system and stores the operation time in a memory while outputting broadcasting information transmitted from a tuner through an image display unit(204). The memory accumulates the actual operation time of the video system, which is continuously provided(205). The microcomputer reads the actual operation time and accumulated time stored in the memory to provide them to an OSD(On Screen Display) and a display(206). When a user selects an OSD menu, the OSD displays the actual operation time and accumulate time to the user(207). The display displays the actual operation time and accumulated time in figures or a bar form(208).

Abstract: A method for controlling congestion in an ATM network is provided to set a congestion-prevent threshold value, and to request a traffic rate to be reduced when traffic statistical information exceeds the threshold value during a service, thereby preventing congestion while guaranteeing voice QoS. An ATM switch decides whether a traffic statistical value exceeds a congestion-prevent threshold value(S10,S12,S14). If so, the switch transmits information showing the exceeded statistical value to a receiving end(S16). An ATM switch of the receiving end sets a congestion experience display to be on, and transmits an ATM cell of an AAL5 PDU type whose congestion experience display is set to be on to other receiving end(S18,S20,S22). The other receiving end requests a transmission end to reduce a traffic rate(S24,S26). The transmission end reduces the traffic rate(S28), and transmits information showing that the statistical value is less than the threshold value(S30,S32). The ATM switch of the receiving end sets the congestion experience display to be off, and sends an ATM cell of an AAL5 PDU type having the off display to the other receiving end(S34,S36,S38). The other receiving end requests the transmission end to increase the traffic rate(S40,S42).
