This paper describes the design and implementation of MBS (multicast & broadcast service) server for mobile IPTV service in WiMAX networks. Based on interoperability requirements of WiMAX networks, the presented MBS server was implemented for mobile IPTV services and basically provides MBS service announcement and session management functions, dynamic MBS zone management, and MBS data transmission.
In this paper, a novel prefix-based patching algorithm named DP2 (Dynamic Prefix-based Patching algorithm) is proposed for mobile IPTV service in the WiBro system. Proposed algorithm increase the resource utilization of wireless bandwidth and server. It uses the prefix caching in proxy server to batch those requests that demand the same video. This algorithm just requires the mobile terminal can receive...
The main purpose of this paper is the functional design of BM-SC (Broadcast Multicast Service Centre) to support IPTV. BM-SC is newly defined by 3GPP/LTE to support delivering IMS (IP Multimedia Subsystem) over wireless broadband network. Delivering Mobile IPTV (Internet Protocol Television) over LTE (Long Term Evolution) network is requires more complex and more flexible functional operation. A functional...
To provide high quality of multimedia service in mobile environment, mobile IPTV service technology that enables higher reliability of transmission quality and multimedia service to many subscribers has been developed. One of the important technologies for mobile IPTV is to mitigate interference. This can be done by the configuration of MBS zone. 3GPP/LTE and Mobile WiMAX support MBS technology to...
Recently mobile IPTV service becomes primary service to boost sluggish IT industry. SVC service seems to be prominent to satisfy the QoS/QoE in broadcasting service. Especially in multi-screen service, there are many different type of terminal. Therefore contents operator will apply SVC coding scheme to provide appropriate quality of image to users according to multi-terminal type. In order to provide...
To backup the remote education service, the software architecture of IPTV Set-Top device embedding Grid-CDN (Content Delivery Network) based on mesh-pull P2P (Peer-to-Peer) technology has been identified. In this paper, we proposed a method supporting a remote education service such as 1:1 or 1:N between subscribers over IPTV service networks, and implemented on a IPTV Set-Top device. In addition,...
Recently mobile IPTV service becomes primary service to boost sluggish IT industry. Also 3D image seems to be more prominent in broadcasting service. Therefore 3D image service over mobile IPTV service network will appear as key converging telecommunications and broadcasting service. In order to provide 3D image in wireless access network, it's necessary to enhance the capacity of wireless access...
For converged technology both broadcasting and communication, currently mobile IPTV is focused on portable broadcasting system with users' feedback. To implement mobile IPTV based on mobile communication, the MIMO technique is necessary due to increasing capacity and applying different modulation ratio. In this paper, we proposed decision vector. The decision vector improves system performance by...
It's necessary to enhance the capacity of wireless access network to provide mobile IPTV service. In this paper MMR(Mobile Multi-hop Relay) system is introduced to increase the performance of mobile system based on IEEE 802.16m which introduced network coding technology to increase the performance of radio link. Radio link quality and mobile terminal throughput are analysed by simulation when RS(Relay...
