MPEG-Layer 3 Bitstream Syntax And Decoding
White Papers This document describes the bitstream syntax of the ISO/MPEG Layer3 bitstream. This standard defines the bitstream for audio signals with sampling frequencies of 32 kHz, 44.1 kHz and 48 kHz. This is a syntax extension of the MPEG Layer3 bitstream...

A Delphi Assessment Of The Digital Rosetta Stone Model
White Papers If the methods to retrieve the bitstream are lost, it may be difficult, if not impossible to re-create them. The knowledge to interpret the bitstream is also at risk. Information that is stored digitally can only be used if it can be retrieved and...

Low-Complexity Automatic Speaker Recognition In The Compressed GSM AMR Domain
White Papers The goal is to perform speaker modeling and identification without decoding the speech bitstream to extract speaker dependent features, thus saving important system resources, for instance, in mobile devices.

Error-Resilient Unequal Protection Of Fine Granularity Scalable Video Bitstreams
White Papers Unlike many other existing protection schemes, it develops an Error-Resilient UnEqual Protection (ER-UEP) method that adds redundant information optimally for loss protection and, at the same time, cancels completely the dependency among bitstream...

Motion Adaptive Intra Refresh For MPEG-4
White Papers This white paper examines the sensitivity to error of a video bitstream often changes as the amount of motion within a scene changes. The effect of data loss on video often depends upon the amount of motion taking place within the frame.

Modelling H.264/AVC Sensitivity For Error Protection In Wireless Transmissions
White Papers A simple method is proposed to optimise the protection levels on the different parts of an H.264/AVC bitstream for transmission over an error-prone channel. This method relies on a semi-analytical model of the video stream sensitivity that allows...
