Abstract

WiMAX is the emerging BWA (Broadband Wireless Access) technology of next generation because of its mobility, coverage and high transmission speed. Therefore, many diversified network applications and services can be applied further for the prevalence of nomadic clients. In this paper, we introduce a new network deployment of WiMAX to effectively provide high-quality video streaming of live news reporting (i.e. LNR) for TV stations in Taiwan, Both services of WiTV (IPTV over WiMAX) and e-SNG (WiMAX News Gathering) are provided for users and reporters respectively in proposed WiMAX deployment. Besides, to effectively provide LNR service, this island-wide WiMAX network deployment with access range of more than 350Km applies not only the relays of digital microwave links with end-to-end distance reaching to 70Km, but also the port-based VLANs to differentiate services to guarantee quality of service for LNR without interference from other irrelevant traffics. On the test-bed of proposed WiMAX deployment, the performance results from experiments on H.264/SD video streaming demonstrate cost-effectiveness and feasibility of LNR for TV stations.

高质量视频流直播新闻报道的经济高效的WiMAX部署

WiMAX是新兴的下一代宽带无线接入(BWA)技术，因为它具有移动性、覆盖范围和高传输速度。因此，许多多样化的网络应用和服务可以进一步应用于游牧客户端的流行。在本文中，我们介绍了一种新的WiMAX网络部署，以有效地为台湾电视台提供高质量的新闻直播视频流(即LNR)，在提出的WiMAX部署中，分别为用户和记者提供了WiTV (IPTV over WiMAX)和e-SNG (WiMAX news Gathering)服务。此外，为了有效提供LNR业务，本次全岛WiMAX网络部署的接入范围超过350Km，除了采用端到端距离达到70Km的数字微波链路中继外，还采用基于端口的vlan进行业务区分，保证LNR业务质量，不受其他无关业务的干扰。在提出的WiMAX部署测试平台上，H.264/SD视频流的性能实验结果证明了电视台使用LNR的成本效益和可行性。
