Dissecting User Behaviors for a Simultaneous Live and VoD IPTV System
Ning Liu, Huajie Cui, S.-H. Gary Chan, Zhipeng Chen, Yirong Zhuang
Article No.: 23
DOI: 10.1145/2568194

IPTV services deployed nowadays often consist of both live TV and Video-on-Demand (VoD), offered by the same service provider to the same pool of users over the same managed network. Understanding user behaviors in such a setting is hence an...

DIP: Distributed Identification of Polluters in P2P Live Streaming
Rossano Gaeta, Marco Grangetto, Lorenzo Bovio
Article No.: 24
DOI: 10.1145/2568223

Peer-to-peer live streaming applications are vulnerable to malicious actions of peers that deliberately modify data to decrease or prevent the fruition of the media (pollution attack). In this article we propose DIP, a fully distributed,...

Saving Energy in Mobile Devices for On-Demand Multimedia Streaming -- A Cross-Layer Approach
Mohammad Asharful Hoque, Matti Siekkinen, Jukka K. Nurminen, Sasu Tarkoma, Mika Aalto
Article No.: 25
DOI: 10.1145/2556942

This article proposes a novel energy-efficient multimedia delivery system called EStreamer. First, we study the relationship between buffer size at the client, burst-shaped TCP-based multimedia traffic, and energy consumption of wireless network...

A Hamming Embedding Kernel with Informative Bag-of-Visual Words for Video Semantic Indexing
Feng Wang, Wan-Lei Zhao, Chong-Wah Ngo, Bernard Merialdo
Article No.: 26
DOI: 10.1145/2535938

In this article, we propose a novel Hamming embedding kernel with informative bag-of-visual words to address two main problems existing in traditional BoW approaches for video semantic indexing. First, Hamming embedding is employed to alleviate...

Mesh Discriminative Features for 3D Steganalysis
Ying Yang, Ioannis Ivrissimtzis
Article No.: 27
DOI: 10.1145/2535555

We propose a steganalytic algorithm for triangle meshes, based on the supervised training of a classifier by discriminative feature vectors. After a normalization step, the triangle mesh is calibrated by one step of Laplacian smoothing and then a...

A Quality of Experience Model for Haptic Virtual Environments
Abdelwahab Hamam, Abdulmotaleb El Saddik, Jihad Alja'am
Article No.: 28
DOI: 10.1145/2540991

Haptic-based Virtual Reality (VR) applications have many merits. What is still obscure, from the designer's perspective of these applications, is the experience the users will undergo when they use the VR system. Quality of Experience (QoE) is an...

Protecting the Content Integrity of Digital Imagery with Fidelity Preservation: An Improved Version
Marco Botta, Davide Cavagnino, Victor Pomponiu
Article No.: 29
DOI: 10.1145/2568224

Fragile watermarking has attracted a lot of attention in the last decade. An interesting approach, presented in 2011 by Lin et al., results in very high quality of the watermarked images. However, after a thorough examination of the paper, a few...

Identifying Compression History of Wave Audio and Its Applications
Da Luo, Weiqi Luo, Rui Yang, Jiwu Huang
Article No.: 30
DOI: 10.1145/2575978

Audio signal is sometimes stored and/or processed in WAV (waveform) format without any knowledge of its previous compression operations. To perform some subsequent processing, such as digital audio forensics, audio enhancement and blind audio...
