3DTV Broadcasting and Distribution Systems
IEEE Transactions on Broadcasting, 2011In 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.

In a system of recall broadcast, each message contains a set of message identifiers called its recall set. The recall set of a message identifies all previously received messages upon which the message is based. When a message is received by a process and displayed to an external user, all messages in its recall set are also displayed to the user.

New Broadcasting System Combined with Radio Broadcasting and WWW
2008 IEEE International Conference on Web Services, 2008Despite the benefits those communities FM radio broadcasting services provide to their listeners, more than half of the community stations in Japan are struggling financially. This situation has arisen because the Internet has attracted advertising revenue away from radio broadcasting channels. One way to revive local FM radio broadcasting is by adding

AbstractThe paper presents an overview of the systems for mobile broadcast which have been deployed today or are under development. Two examples are explained in some detail, namely DVB‐H and DVB‐SH. In addition, the need of ‘higher layer’ solutions is identified and IP Datacast is briefly explained. Copyright © 2009 John Wiley & Sons, Ltd.

Broadcast anti-jamming systems
IEEE International Conference on Networks. ICON '99 Proceedings (Cat. No.PR00243), 2005In a traditional anti-jamming system a transmitter who wants to send a signal to a single sender 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 sender wants to broadcast a message to all receivers such ...

A Layered Broadcast Cryptographic System
1984A 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.
