Broadcast anti-jamming systems

Computer Networks, 2001
In a traditional anti-jamming system a transmitter who wants to send a signal to a single receiver spreads the signal power over a wide frequency spectrum with the aim of stopping a jammer from blocking the transmission. In this paper, we consider the case that there are multiple receivers and the transmitter wants to broadcast a message to all ...

Hybrid Broadcasting System for Webcast

2016 19th International Conference on Network-Based Information Systems (NBiS), 2016
Due to the recent popularization of hybrid webcast environments, streaming delivery using broadcast and telecommunication is attracting great attention. In streaming delivery on the hybrid broadcasting environment, clients concurrently receive streaming data such as music or movies from both broadcasting and telecommunication systems.

A Haptically Enhanced Broadcasting System

First Joint Eurohaptics Conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems, 2005
In this paper, we discuss a haptically enhanced broadcasting system. Four stages of a proposed system are briefly analyzed: scene capture, edit, transmission, and display with haptic interaction. In order to show usefulness of the proposed system, a potential home shopping scenario is implemented.

3DTV Broadcasting and Distribution Systems

IEEE Transactions on Broadcasting, 2011
In this paper, the authors present three-dimensional television (3DTV) broadcasting and distribution systems that are employed to deliver a pair of stereoscopic images to mobile users, as well as users at home. First, mobile 3DTV systems and services based on DMB and DVB-H are respectively introduced.

Windows Scheduling Problems for Broadcast Systems

SIAM Journal on Computing, 2003
Summary: The windows scheduling problem is defined by the positive integers \(n\), \(h\), and \(w_{1}, \dots ,w_{n}\). There are \(n\) pages where the window \(w_{i}\) is associated with page \(i\), and \(h\) is the number of slotted channels available for broadcasting the pages.

HDTV broadcasting systems

IEEE Communications Magazine, 1991
A brief overview of HDTV broadcasting in the USA, Japan, and Europe is given. The requirements for HDTV broadcast systems are examined. The issue of compatibility is discussed. Standardization activities for HDTV broadcasting are described. The Japanese MUSE (multiple sub-Nyquist sampling encoding) system and the European HD-MAC (high-definition ...

Development of SRI's translation systems for broadcast news and broadcast conversations

Interspeech 2008, 2008
We present our recent work on developing large-vocabulary Arabic-to-English and Chinese-to-English speech-to-text translation systems for the January 2008 Global Autonomous Language Exploitation (GALE) retest evaluation. Two audio genres were involved in the evaluation: broadcast news and broadcast conversation.

Terrestrial broadcast technologies for next generation broadcast wireless systems

2015 IEEE International Conference on Communication Workshop (ICCW), 2015
The next generation broadcast wireless (NGB-W) system is aimed to provide high-speed, ubiquitous, and secure tri-play services to massive users. In this paper, a new terrestrial broadcast solution for the NGB-W system is proposed. The system and the key techniques of the proposed solution are introduced.

A Layered Broadcast Cryptographic System

1984
A new type of cryptosystem is presented that may find application in broadcast communication networks and database systems. To date, all proposals for such systems have either been shown to be weak under cryptanalytic attack or to possess undesirable characteristics such as data expansion.

The Wakeup Problem in Synchronous Broadcast Systems

SIAM Journal on Discrete Mathematics, 2001
Summary: This paper studies the differences between two levels of synchronization in a distributed broadcast system (or a multiple-access channel). In the globally synchronous model, all processors have access to a global clock. In the locally synchronous model, processors have local clocks ticking at the same rate, but each clock starts individually ...
