The VISNET II DVC codec: architecture, tools and performance

Touradj Ebrahimi, Frédéric Dufaux

This paper introduces the VISNET II DVC codec. This co-dec achieves very high RD performance thanks to the efficient combination of many state-of-the-art coding tools into a fully practical video codec. Experimental results show that the proposed DVC codec ...

CAL Dataflow Components For an MPEG RVC AVC Baseline Encoder

Marco Mattavelli, Ihab Mostafa Amin Mohamed Amer, Hussein Aman-Allah

In this paper, an efficient H.264/AVC baseline encoder, described in RVC-CAL actor language, is introduced. The main aim of the paper is two folds: a) to demonstrate the flexibility and ease that is provided by RVC-CAL, which allows for efficient implement ...

Towards a Comprehensive RVC VTL: A CAL Description of an Efficient AVC Baseline Encoder

Ihab Mostafa Amin Mohamed Amer, Hussein Aman-Allah

The Video Tool Library (VTL) is one of the major normative components of the Reconfigurable Video Coding (RVC) standard. It specifies the set of functional units (FUs)that may be interchangeably combined and connected to form different video codecs, with v ...

Modeling and Analysis of Distortion Caused by Markov-Model Burst Packet Losses in Video Transmission

Yi Zhang

This paper addresses the problem of distortion modeling for video transmission over burst-loss channels characterized by a finite state Markov chain. Based on a detailed analysis of the error propagation and the bursty losses, a Distortion Trellis model is ...
