ABSTRACT:
A packet converting apparatus and method is disclosed, in which audio packet data of various types used in cable/radio networks can effectively be converted. The packet converting apparatus includes a bit unpacking unit for bit unpacking first type packet data, a parameter inverse quantization unit for inverse quantizing the unpacked data to obtain a main parameter of the first type packet data, a parameter converter for converting the obtained main parameter to a parameter of second type packet data through inter-frame interpolation, a quantization unit for quantizing the second type parameter converted by the parameter converter, and a bit packing unit for bit packing the quantized data to reassemble the bit packed data to second type packet data and output the second type packet data to a destination.
