Single-Channel Data Broadcasting under Small Waiting Latency [PDF]
Journal of Applied Mathematics, 2013 Due to the advancement of network technology, video-on-demand (VoD) services are growing in popularity. However, individual stream allocation for client requests easily causes a VoD system overload; when its network and disk bandwidth cannot match client

Repetition-Based Cooperative Broadcasting for Vehicular Ad Hoc Networks Under the Rayleigh Fading Channel [PDF]
Applied Sciences, 2019 In vehicular ad hoc networks (VANETs), safety applications require a reliable and delay-guaranteed broadcasting service to disseminate safety messages. However, channel fading and the high mobility of vehicles make it very challenging for a broadcasting ...

The Mediating Role of Interaction Between Watching Motivation and Flow of Sports Broadcasting in Multi-Channel Network [PDF]
SAGE Open, 2022 This study aimed to grasp the structural path to watchers’ flow by applying watching motivation to multi-channel network (MCN), which is spreading as a new sports broadcasting medium and to emphasize the role of interaction in MCN.

Separate source-channel coding for broadcasting correlated Gaussians [PDF]
, 2011 The problem of broadcasting a pair of correlated Gaussian sources using optimal separate source and channel codes is studied. Considerable performance gains over previously known separate source-channel schemes are observed.

Identification Over Quantum Broadcast Channels [PDF]
arXiv, 2022 Identification over quantum broadcast channels is considered. As opposed to the information transmission task, the decoder only identifies whether a message of his choosing was sent or not. This relaxation allows for a double-exponential code size.

Secrecy in Cooperative Relay Broadcast Channels [PDF]
arXiv, 2008 We investigate the effects of user cooperation on the secrecy of broadcast channels by considering a cooperative relay broadcast channel. We show that user cooperation can increase the achievable secrecy region. We propose an achievable scheme that combines Marton's coding scheme for broadcast channels and Cover and El Gamal's compress-and-forward ...

The role of the public service broadcasting in the european countries [PDF]
Annals of the University of Oradea: Economic Science, 2008 Broadcasting in particular has seen remarkable change from the days of single-channel public broadcasting systems. The audiovisual “explosion” is a cultural, social and economic phenomenon of global dimension.

Network Code Design for Orthogonal Two-Hop Network with Broadcasting Relay: A Joint Source-Channel-Network Coding Approach [PDF]
, 2011 This paper addresses network code design for robust transmission of sources over an orthogonal two-hop wireless network with a broadcasting relay. The network consists of multiple sources and destinations in which each destination, benefiting the relay ...

Information Theoretic Security for Broadcasting of Two Encrypted Sources under Side-Channel Attacks † [PDF]
, 2019 We consider the secure communication problem for broadcasting of two encrypted sources. The sender wishes to broadcast two secret messages via two common key cryptosystems. We assume that the adversary can use the side-channel, where the side information

2023 IEEE International Symposium on Information Theory (ISIT), 2023 We study the problem of random-assisted simulation of discrete broadcast channel in one-shot and i.i.d. setups. We derive one-shot inner and outer bounds of the set of attainable message-size pairs for simulating W YZ|X within some total variation distance (TVD) tolerance of ϵ. The inner bounds are based on the bipartite convex split lemma. Whereas the
