Emerging high efficiency video compression methods and wider availability of wireless network infrastructure will significantly advance existing m-health applications. For medical video communications, the emerging video compression and network standards support low-delay and high-resolution video transmission, at the clinically acquired resolution and frame rates. Such advances are expected to further promote the adoption of m-health systems for remote diagnosis and emergency incidents in daily clinical practice. This paper compares the performance of the emerging high efficiency video coding (HEVC) standard to the current state-of-the-art H.264/AVC standard. The experimental evaluation, based on five atherosclerotic plaque ultrasound videos encoded at QCIF, CIF, and 4CIF resolutions demonstrates that 50% reductions in bitrate requirements is possible for equivalent clinical quality.
新兴的高效视频压缩方法以及无线网络基础设施更广泛的可用性将极大地推动现有的移动医疗应用。对于医学视频通信而言，新兴的视频压缩和网络标准支持以临床采集的分辨率和帧率进行低延迟、高分辨率的视频传输。预计这些进展将进一步推动移动医疗系统在日常临床实践中用于远程诊断和紧急事件。本文将新兴的高效视频编码（HEVC）标准的性能与当前最先进的H.264/AVC标准进行了比较。基于以QCIF、CIF和4CIF分辨率编码的五个动脉粥样硬化斑块超声视频的实验评估表明，在等效临床质量下，比特率需求可降低50%。
