Abstract: The present disclosure relates to an overcurrent protection inverter, and more particularly, to an inverter, which uses a leg-shunt resistor so as to detect an instantaneous maximum output current and an AD current, thereby performing an inverter protection operation. The present disclosure detects the instantaneous maximum output current and detects the AD current from the leg-shunt resistor so as to perform an overcurrent protection operation when an overcurrent occurs in the entire inverter operation section, thereby enabling protection of the inverter.

Abstract: The present invention relates to a cloud streaming service system, a data compressing method for preventing memory bottlenecking, and a device for same and, particularly, to a technology that: can prevent memory bottlenecking by compressing data when the transmitted amount of original buffer data exceeds a reference value, based on a system memory bandwidth; can provide a cloud streaming service by applying an order of priority by service type according to whether the processing limit, for the number of simultaneous connecting entities that can be processed by one server, is reached during a cloud streaming service; and can test whether a sever that provides a cloud streaming service is operating normally and whether a connection error occurs.

Abstract: Provided are alternatives for improving coding efficiency when an AR-FGS technique and an FGS motion refinement technique are applied to scalable video coding. When prediction of a residual signal an FGS layer is not performed, a ? prediction signal of block related to the FGS layer is predicted in the same manner as the manner of predicting a prediction signal of a base quality layer. A scaling factor is allowed to have a non-zero value if required, and the residual signal of the FGS layer is used to determine a scaling factor of a higher FGS layer. The AR-FGS and FGS motion refinement techniques are restricted from being simultaneously used for key pictures.
