Abstract

The Long Term Evolution (LTE) cellular technology provides higher data rates than its predecessor technologies. This advancement paves the way for more data services, including improved multimedia services. Three-dimensional (3D) video transmission is one such service that can benefit from LTE deployment. For a positive uptake of 3D video transmission, the network must provide a good Quality of Service (QoS). In this paper the authors evaluate the LTE network's performance when transmitting Multi-view Video Coding (MVC) using simulcast and inter-view prediction coding. Furthermore, the authors evaluate the system using both the H.264/AVC (Advanced Video Coding) and the more recent High Efficiency Video Coding (HEVC) and their MVC extensions. Results show that, in an urban environment, LTE can accommodate a maximum of 93 users per cell, with adequate QoS, when transmitting 3D HEVC video at Common Intermediate Format (CIF) resolution. Moreover, cross-layer techniques can be used to reduce the QoS degradation as the user moves away from the eNodeB by transmitting lower resolution video.

传输多视点视频内容时长期演进蜂窝网络性能的评估

长期演进(LTE)蜂窝技术提供比其前身技术更高的数据速率。这一进步为更多的数据服务铺平了道路，包括改进的多媒体服务。三维(3D)视频传输就是这样一种可以从LTE部署中受益的服务。为了积极地采用3D视频传输，网络必须提供良好的服务质量(QoS)。本文对LTE网络在传输多视点视频编码(MVC)时采用联播和视点间预测编码的性能进行了评估。此外，作者使用H.264/AVC(高级视频编码)和最新的高效视频编码(HEVC)及其MVC扩展对系统进行了评估。结果表明，在城市环境中，当以通用中间格式(CIF)分辨率传输3D HEVC视频时，LTE每个小区最多可容纳93个用户，并具有足够的QoS。此外，当用户通过传输低分辨率视频而远离eNodeB时，可以使用跨层技术来减少QoS退化。
