Multi-Frequency Tracking via Group-Sparse Optimal Transport

In this letter, we introduce an optimal transport framework for inferring power distributions over both spatial location and temporal frequency. Recently, it has been shown that optimal transport is a powerful tool for estimating spatial spectra that chang ...

Infrastructures of Solidarity, Infrastructures of Totalitarism

Alfredo Thiermann

Between 11 September 1973 and 11 March 1990, the silenced voices of many were dissolved into electromagnetic waves so they could be transmitted and heard in Chile. For sixteen years, the broadcasting house of the German Democratic Republic (GDR) – the Funk ...

Platform-mediated live musical performance in China: New social practices and urban cultural spaces

Mengke Zhang

This paper provides a non-Anglo-American geographical discussion of digitally mediated cultural activities. Taking China's live music industry as an entry point, we seek to theoretically and empirically understand the complex roles of digital technologies ...

Global Auto-regressive Depth Recovery via Iterative Non-local Filtering

Pascal Frossard, Jingyu Yang, Xinchen Ye

Existing depth sensing techniques have many shortcomings in terms of resolution, completeness, and accuracy. The performance of 3-D broadcasting systems is therefore limited by the challenges of capturing high-resolution depth data. In this paper, we prese ...

Quality assessment of an HDR dual-layer backward-compatible codec compared to uncompromised SDR and HDR solutions

Touradj Ebrahimi, Martin Rerabek, Anne-Flore Nicole Marie Perrin

Broadcasting high dynamic range (HDR) video has been demonstrated as largely preferred when compared to standard dynamic range (SDR), mainly due to its capability of representing more details in dark and bright regions. Additionally, progress over the last ...

Throughput Analysis of Large Networks

Serj Haddad

While wired infrastructure constitutes the backbone of most wireless networks, wireless systems appeal the most to the dynamic and rapidly evolving requirements of today's communication systems because of their ease of deployment and mobility, not to menti ...

Cooperative data exchange based on MDS codes

Michael Christoph Gastpar, Su Li

The coded cooperative data exchange problem is studied for the fully connected network. In this problem, each node initially only possesses a subset of the K packets making up the file. Nodes make broadcast transmissions that are received by all other node ...

Learning Multimodal Temporal Representation for Dubbing Detection in Broadcast Media

Jean-Marc Odobez

Person discovery in the absence of prior identity knowledge requires accurate association of visual and auditory cues. In broadcast data, multimodal analysis faces additional challenges due to narrated voices over muted scenes or dubbing in different langu ...

Profit Optimization for Wireless Video Broadcasting Systems Based on Polymatroidal Analysis

Pascal Frossard, Yiqiang Chen

This study addresses the problem of profit maximization between wireless service providers (WSPs) and content providers (CPs) in wireless broadcasting systems, while simultaneously providing high quality of experience for end-users (EUs). We first study th ...
