Video-on-demand (VoD) systems that can serve hundreds to thousands of concurrent users are already widely available. However, to deploy metropolitan-scale VoD services for potentially tens of millions of users, current VoD systems are still limited in capacity, and expensive in cost. To tackle this challenge, this study proposes a new periodic broadcasting scheme, called Constrained Consonant B...

Since digital radio broadcasting techniques can give highly enhanced performance and quality (e.g. CD like audio quality, single frequency network, slide show, etc), many countries pay attention to converting their analog radio broadcasting services into digital services. In Korea, to digitize radio broadcasting service, various trials have been executed since 2009 [1]-[2]. This paper deals wit...

This paper presents the field trial results of digital audio broadcasting (DAB), DAB+ and terrestrial-digital multimedia broadcasting (TDMB) audio systems to provide useful information about each digital radio broadcasting standard. Although the all methods are representative digital radio broadcasting standards based on Eureka-147, they have different parts from each other. This field trial re...

Intelligent Transportation Systems (ITS), which rely on vehicular ad hoc communication networks (VANETs), have the potential to alleviate road accidents and to save lives. Several use cases to VANETs safety applications have been proposed. Most of these applications use multi-hop broadcasting communications to disseminate safety information as far as needed in zones of relevance. A wide variety...

In this paper, we demonstrate an immersive and interactive broadcasting production system with a new haptically enhanced multimedia broadcasting chain. The system adapts Augmented Reality (AR) techniques, which merges captured videos and virtual 3D media seamlessly through multimedia streaming technology, and haptic interaction technology in near real-time. In this system, viewers at the haptic...

In Private Broadcasting, a single plaintext is broadcast to multiple recipients in an encrypted form, such that each recipient can decrypt locally. When the message classical, straightforward solution encrypt with key shared among all parties, and send copy of ciphertext. Surprisingly, analogous method insufficient case where quantum (i.e. Quantum Broadcasting (QPB)). this work, we give three s...
