Three-Receiver Broadcast Channels With Common and Confidential Messages
Secrecy capacity regions three-receiver broadcast channels wiretap channels
2015/8/12
This paper establishes inner bounds on the secrecy capacity regions for the general three-receiver broadcast channel with one common and one confidential message sets. We consider two setups. The firs...
A Note on the Broadcast Channel With Stale State Information at the Transmitter
Broadcast channel channel with state feedback source coding with side information
2015/8/12
This paper shows that the Maddah-Ali–Tse (MAT) scheme, which achieves the symmetric capacity of two example broadcast channels with strictly causal state information at the transmitter, is a simple sp...
Collusion Resistant Broadcast Encryption With Short Ciphertexts and Private Keys
Resistant Broadcast Encryption Short Ciphertexts
2015/8/5
We describe two new public key broadcast encryption systems for stateless receivers. Both systems are fully secure against any number of colluders. In our first construction both ciphertexts and priva...
Low Overhead Broadcast Encryption from Multilinear Maps
Multilinear Maps Broadcast Encryption
2015/8/5
We use multilinear maps to provide a solution to the long-standing problem of public-key
broadcast encryption where all parameters in the system are small. In our constructions,
ciphertext overhead,...
Event Tactic Analysis Based on Broadcast Sports Video
Event Tactic Analysis Broadcast Sports Video
2013/7/16
Most existing approaches on sports video analysis have concentrated on semantic event detection. Sports professionals, however, are more interested in tactic analysis to help improve their performance...
Highlight Ranking for Broadcast Tennis Video Based on Multi-modality Analysis and Relevance Feedback
Highlight ranking multi-modality analysis relevance feedback sports video analysis
2013/7/17
Most of existing work on sports video analysis concentrates on highlight extraction. Few efforts devoted to the important issue as how to organize the extracted highlights which is adapt for the...
Naming Faces in Broadcast News Video by Image Google
News video analysis naming faces news video browsing and indexing
2013/7/17
Naming faces is important for news videos browsing and indexing. Although some research efforts have been contributed to it, they only use the concurrent information between the face and name or empl...
LOWER ATTENTIVE REGION DETECTION FOR VIRTUAL CONTENT INSERTION IN BROADCAST VIDEO
Lower Attention Region Virtual Content Insertion Visual Attention Information Theory
2013/7/17
Virtual Content Insertion (VCI) is an emerging application of video analysis. For VCI the spatial position is very important as improper placement will make the insertion intrusive. To choose the spat...
ONLINE INDUSTRIAL PROCESS BROADCAST AND CONTROL BASED ON IP AND SERIAL NETWORKS
control fieldbus industrial network
2010/1/11
The Internet network in conjunction with a strong security policy can be an
ideal online broadcast system for the industrial processes monitoring and control. Because
the distributed controllers are...
Exciting Event Detection in Broadcast Soccer Video with Mid-level Description and Incremental Learning
Sports video analysis exciting event detection
2013/7/23
In this paper, we propose a method for exciting event detection in broadcast soccer video with mid-level description and SVM-based incremental learning. In the method, video frames are firstly classif...
