At the time of this paper, high dynamic range (HDR) visualization has already emerged in both the industry and the commercial sector, with HDR displays already present on the consumer market and the technology marching towards the goal of becoming the de facto format of multimedia. HDR is thus often looked at and praised as the next logical step in the evolution of audiovisual entertainment. However, there is no such thing as a single, universal HDR standard, and the competing market projects a future with even more diversity in format specifications, display capabilities and content characteristics. As the competitors attempt to surpass each other and obtain a bigger share of the global market, they inevitably bombard the potential customers and users with brief but effective labels that reflect excellence and superior quality. In this paper, the cognitive effect of such labels is investigated. As home video entertainment is possibly the most numerous instance of the future usage of this visualization technology, video streaming is particularly addressed. Since real-time video transmission services are bound to suffer playback interruptions upon insufficient data rates and uncompensated drops in the available bandwidth, stalling events experienced in conventional multimedia streaming shall apply to HDR video as well. The paper presents four separate experiments, studying how the cognitive bias caused by the labeling effect influences the perception of HDR quality aspects and stalling events, and how the cognitive load varies for stalling detection thresholds between conventional and HDR visualization.

标签对HDR视频传输感知质量的影响

在撰写本文时,工业和商业领域均已出现高动态范围 (HDR) 可视化,消费市场上已经出现 HDR 显示器,并且该技术正朝着成为事实上的多媒体格式的目标迈进. 因此,HDR 经常被视为视听娱乐发展的下一个合乎逻辑的步骤并受到称赞。然而,不存在单一的、通用的 HDR 标准,竞争市场预示着未来在格式规范、显示能力和内容特征方面会更加多样化。在竞争者试图超越对方并在全球市场获得更大份额的过程中,他们不可避免地以简短而有效的标签轰炸潜在客户和用户,这些标签体现了卓越和卓越的品质。在本文中,研究了这些标签的认知效应。由于家庭视频娱乐可能是这种可视化技术未来使用最多的实例,因此视频流尤其受到关注。由于实时视频传输服务必然会因数据速率不足和可用带宽的未补偿下降而遭受播放中断,因此传统多媒体流中遇到的停顿事件也应适用于 HDR 视频。该论文提出了四个独立的实验,研究由标记效应引起的认知偏差如何影响对 HDR 质量方面和停顿事件的感知,以及认知负荷如何因传统和 HDR 可视化之间的停顿检测阈值而变化。由于家庭视频娱乐可能是这种可视化技术未来使用最多的实例,因此视频流尤其受到关注。由于实时视频传输服务必然会因数据速率不足和可用带宽的未补偿下降而遭受播放中断,因此传统多媒体流中遇到的停顿事件也应适用于 HDR 视频。该论文提出了四个独立的实验,研究由标记效应引起的认知偏差如何影响对 HDR 质量方面和停顿事件的感知,以及认知负荷如何因传统和 HDR 可视化之间的停顿检测阈值而变化。由于家庭视频娱乐可能是这种可视化技术未来使用最多的实例,因此视频流尤其受到关注。由于实时视频传输服务必然会因数据速率不足和可用带宽的未补偿下降而遭受播放中断,因此传统多媒体流中遇到的停顿事件也应适用于 HDR 视频。该论文提出了四个独立的实验,研究由标记效应引起的认知偏差如何影响对 HDR 质量方面和停顿事件的感知,以及认知负荷如何因传统和 HDR 可视化之间的停顿检测阈值而变化。由于实时视频传输服务必然会因数据速率不足和可用带宽的未补偿下降而遭受播放中断,因此传统多媒体流中遇到的停顿事件也应适用于 HDR 视频。该论文提出了四个独立的实验,研究由标记效应引起的认知偏差如何影响对 HDR 质量方面和停顿事件的感知,以及认知负荷如何因传统和 HDR 可视化之间的停顿检测阈值而变化。由于实时视频传输服务必然会因数据速率不足和可用带宽的未补偿下降而遭受播放中断,因此传统多媒体流中遇到的停顿事件也应适用于 HDR 视频。该论文提出了四个独立的实验,研究由标记效应引起的认知偏差如何影响对 HDR 质量方面和停顿事件的感知,以及认知负荷如何因传统和 HDR 可视化之间的停顿检测阈值而变化。
