Abstract:
The method for encoding data includes: receiving data; determining one quantizer from among a plurality of quantizers having a same quantization step size and different offset values; and transmitting an indicator and a quantized coefficient related to the determined quantizer. The method for decoding data includes: receiving an indicator and a quantized coefficient related to a quantizer; determining one de-quantizer from among a plurality of de-quantizers by using the indicator; and acquiring reconstructed data by de-quantizing the quantized coefficient by using the determined de-quantizer.
