We derive an optimization framework for joint view and rate scalable coding of multi-view video content represented in the texture plus depth format. The optimization enables the sender to select the subset of coded views and their encoding rates such that ...
This paper proposes an efficient video coding method using audio-visual focus of attention, which is based on the observation that sound-emitting regions in an audio-visual sequence draw viewers' attention. First, an audio-visual source localization algori ...
Many distributed multimedia applications rely on video analysis algorithms for automated video and image processing. Little is known, however, about the minimum video quality required to ensure an accurate performance of these algorithms. In an attempt to ...
Delivering multiview video content over present packet networks poses multiple challenges. First, the best effort nature of the Internet exposes media packets to variable bandwidth, loss, and delay as they traverse the network. Second, the prediction depen ...
In this paper, we present a pull-based dissemination protocol for efficient distribution of scalable video content in overlay peer-to-peer networks with mesh structures. The proposed protocol employs prioritized network coding, where the network coded pack ...
The performance of objective quality metrics for high-definition (HD) video sequences is well studied, but little is known about their performance for ultra-high definition (UHD) video sequences. This paper analyzes the performance of several common object ...
Increasingly popular multimedia services are expected to play a dominant role in the future of the Internet. In this context, it is essential that content-aware networking (CAN) architectures explicitly address the efficient delivery and processing of mult ...

A method of providing SVC video content with added media content, comprising the steps of: receiving an original video content transmitted from a remote site in a bit stream and including original video encoding parameters decoding said original video enco ...
Given recent developments in information technology and intellectual property (IP) legislation, technology firms may benefit from an integrated IP strategy that combines patenting with strategic disclosure. This article presents a series of cases that intr ...
The electrical consumption of the core global networks is becoming preoccupant. To reduce it, one may bet on technological advances improving the energetic profile of individual components. However, large energy savings can potentially already be achieved, ...
