Non-uniform QMF Decomposition for Wide-band Audio Coding based on Frequency Domain Linear Prediction

Petr Motlicek, Hynek Hermansky, Sriram Ganapathy

This paper presents a new technique for perfect reconstruction non-uniform QMF decomposition developed to increase efficiency of a generic wide-band audio coding system based on Frequency Domain Linear Prediction (FDLP). The base line FDLP codec, operating ...

Robust Transmission of Multi-View Video Streams Using Flexible Macroblock Ordering and Systematic LT codes

Nikolaos Thomos, Erdal Arikan

The transmission of fully compatible H.264/AVC multi-view video coded streams over packet erasure networks is examined. Macroblock classification into unequally important slice groups is considered using the flexible macroblock ordering (FMO) tool of H.264 ...

Distributed Spatial Audio Coding in Wireless Hearing Aids

Martin Vetterli, Olivier Roy

The information content of binaural signals can be beneficial to many algorithms deployed in current digital hearing aids. However, the exchange of such signals over a wireless communication link requires transmission schemes that must fulfill demanding te ...

Multiple Description H.264 Coding with Redundant Pictures

Pascal Frossard, Ivana Radulovic

Multiple description coding (MDC) o®ers a competitive so- lution for video transmission over lossy packet networks, with a graceful degradation of the reproduced quality as the loss rate increases. This paper illustrates how redundant pictures, an error re ...

Low delay video coding

Analogue wireless cameras have been employed for decades, however they have not become an universal solution due to their difficulties of set up and use. The main problem is the link robustness which mainly depends on the requirement of a line-of-sight vie ...

Flexible Motion-Adaptive Video Coding with Redundant Expansions

Pascal Frossard, Pierre Vandergheynst, Adel Rahmoune

This paper presents a highly flexible video coding scheme (MP3D), based on the use of a redundant 3-D spatio-temporal dictionary of functions. Directionality and anisotropic scaling are key ingredients to the spatial components, that form a rich collection ...

Unbalanced Quantized Multi-State Video Coding

Pascal Frossard

Multi-State Video Coding (MSVC) is a multiple description scheme based on frame-wise splitting of the video sequence into two or more subsequences. Each subsequence is encoded separately to generate descriptions which can be decoded independently. Due to s ...

Recent Advances in MPEG-7 Cameras

Touradj Ebrahimi

We propose a smart camera which performs video analysis and generates an MPEG-7 compliant stream. By producing a content-based metadata description of the scene, the MPEG-7 camera extends the capabilities of conventional cameras. The metadata is then direc ...

A methodology and supporting tools for the development of component-based embedded systems

Joseph Sifakis, Marc Poulhiès

The paper presents a methodology and supporting tools for developing component-based embedded systems running on resource-limited hardware platforms. The methodology combines two complementary component frameworks in an integrated tool chain: BIP and Think ...

Efficient error correction solutions for OFDM based digital video

Mauro Lattuada

The robustness of the delivery of digital compressed video streams has always been one of the main topic of the standardization bodies to assure the Quality of the Service (QoS). The MPEG standard which is nowadays the reference for digital television defi ...
