Abstract
Official abstract text for this publication.
A quantizing method is provided that includes quantizing an input signal by selecting one of a first quantization scheme not using an inter-frame prediction and a second quantization scheme using the inter-frame prediction, in consideration of one or more of a prediction mode, a predictive error and a transmission channel state.
First claim
Opening claim text (preview).
What is claimed is: 1. A quantizing method comprising: selecting, based on a predictive error, one of a first quantization module without inter-frame prediction and a second quantization with the inter-frame prediction, in an open-loop manner; and quantizing, performed by a processor, an input signal using the selected quantization module. 2. The quantizing method of claim 1 , wherein the first quantization module comprises a trellis-structured quantizer w…
