Low bit rate coding for speech and audio using mel linear predictive coding (MLPC) analysis
This paper proposes a low bit rate coding method for speech and audio using a new analysis method named MLPC (Mel-LPC analysis). In the MLPC analysis method a spectrum envelope is estimated on a melor bark-frequency scale, so as to improve the spectral resolution in the low frequency band. This analysis is accomplished with about two-fold increase in computation over the standard LPC analysis. ...
متن کاملA Low Bit Rate Video Codec
video coding, low bit rate, morphological segmentation, wavelet A video coding/decoding system for applications requiring low bit rate has been developed. This coding scheme uses an intraframe coder for the initial frame in the video sequence and subsequent frames are coded using an interframe coding method. A wavelet-based technique is used for intraframe coding. For interframe coding, displac...
متن کاملAn Enhanced Low Bit Rate Audio Codec Using Discrete Wavelet Transform
Audio coding is the technology to represent audio in digital form with as few bits as possible while maintaining the intelligibility and quality required for particular application. Interest in audio coding is motivated by the evolution to digital communications and the requirement to minimize bit rate, and hence conserve bandwidth. There is always a tradeoff between lowering the bit rate and m...
متن کاملA Hybrid Object-Oriented Very Low Bit Rate Video Codec
There are a large number of applications requiring the compression of video at Very Low Bit Rates (VLBR). Such applications include wireless video conferencing, video over the internet, multimedia database retrieval and remote sensing and monitoring. Recently, the MPEG-4 standardization effort has been a motivating factor to find a solution to this challenging problem. The existing approaches t...
متن کاملLow-delay Predictive Audio Coding for the Hivits Hdtv Codec
This Report describes the work on predictive audio coding carried out by the BBC as part of the RACE 'HIVITS' project. The purpose of the work was to develop and demonstrate a low bit-rate audio codec with low delay for use with a digital HDTV (high definition television) signal coded by the HIVITS HDTV codec and capable of conveying at least 5 channels of audio within the HDTV bitstream.
