摘要:
A codec mode decoding apparatus and method for an AMR communication system for enhancing decoding speed and optimizing memory utilization. The codec mode decoding method includes receiving data encoded using an adaptive multi-rate scheme; extracting a bit value from an informative region of the data by through a channel decoding on the data; producing correlation values by correlating the bit value and at least two codec modes; selecting one of the codec modes, of which correlation value is a maximum likelihood value, as an adapted codec mode; activating a first codec corresponding to the adapted codec mode; and decoding the data using the first codec.

Provided are a regional information extraction method, a regional information output method, and an apparatus for the same. The regional information output method includes obtaining a regional image through the processing unit, transmitting the regional image to a server through the transmitting/receiving unit, receiving regional information on a geographical position that a regional image feature extracted from the regional image represents through the transmitting/receiving unit, and outputting the regional information through the output unit, wherein the geographical position represents one feature matching to the regional image feature, which is selected from a plurality of features representing a plurality of regional images.
