摘要： An apparatus and method are provided for variably transmitting a multimedia stream according to requirements of a client device and the state of a channel. The multimedia stream transmission apparatus includes: a plurality of virtual machines corresponding to the multiple client applications, each of the virtual machines determining a specific parameter set and obtaining a change value for the parameter set from network statistics and a requirement of a corresponding client application; a parameter adjustment unit which adjusts values of parameters used in a network interface by the change value; and the network interface which transmits the multimedia stream based on the adjusted parameters.

摘要： An apparatus and a method for performing encryption or decryption of data in a portable terminal, which performs an encryption or decryption operation from a point where the encryption or decryption operation is not generated when power is turned off and then turned on during the encryption or decryption operation, are provided. The apparatus includes a file system analyzer for extracting information of a data block, in which actual user data is stored, through metadata of a file system, and generating a data block list, and a journaling manager for storing a data block corresponding to the data block list among data blocks stored in a memory in a journaling storage unit, and deleting the data block stored in the journaling storage unit when an encryption or decryption operation for the data block stored in the journaling storage unit is completed.

摘要： Provided is an operating voltage scaling method for a portable terminal. The method includes, if reproduction of a moving image is requested, acquiring DYNamicity (DYN) of the reproduction-requested moving image, determining whether frame skipping is possible for the moving image according to the acquired DYN of the moving image, and if it is determined that frame skipping is possible for the moving image, supplying a low operating voltage to a controller of the mobile terminal to control the mobile terminal to operate with a low-speed clock, and reproducing the moving image while skipping a frame.
