Abstract: A multimedia data reproducing device is provided which includes: a codec converting digital data into an analog signal by a predetermined method and reproducing the analog signal; and a control unit including a core generating a reproduction block by decoding multimedia data and outputting the generated reproduction block to a main memory in an activated state and an interface transmitting the reproduction block stored in the main memory as the digital data to the codec and transmitting the multimedia data stored in an auxiliary memory to the core in an activated state. Accordingly, it is possible to efficiently reproduce multimedia data to reduce the power consumption of a battery by alternately turning on and off a power source of blocks other than the interface in the control unit periodically or depending on a predetermined situation.

Abstract: A velocity measuring device and a measured velocity correcting method are provided. The velocity measuring device includes: a GPS unit that receives a satellite signal from a GPS (Global Positioning System) satellite and generates GPS data including position coordinates and a traveling velocity; an acceleration sensor unit that includes an acceleration sensor and generates sensor data including a traveling velocity and a road slope; and a correction unit that compares the GPS data and the sensor data generated at a current time with the GPS data and the sensor data generated at a previous time and sets the traveling velocity included in the sensor data or the GPS data as a measured velocity depending on whether a variation in traveling velocity exists.
