摘要： An apparatus and method of improving the quality of a speech codec are provided. In the method, a first energy of a signal decoded by a low-band codec is calculated, and a second energy of a signal decoded by a low-band enhancement mode is calculated. Then, when the first energy is less than a first threshold value or less than a product of the second energy and a second threshold value, a size of the decoded signal is scaled. Accordingly, generation of a quantization error with respect to a silence segment is reduced.

摘要： A direct memory access controller (DMAC) for improving data transmission efficiency in multi-media over internet protocol (MMoIP) and a method therefor are provided. The DMAC requests and obtains a bus control right by determining that a DMA request signal is generated not only when a DMA request signal of a module for processing data in MMoIP is received but also when an operation of a timer operating during a predetermined period set considering periodicity of data in MMoIP is completed. Thus, the time taken to request a bus control right in a conventional DMAC can be reduced, thereby improving data transmission efficiency in MMoIP.
