手持设备中的感知等效分辨率用于流媒体带宽节省
Perceptually Equivalent Resolution in Handheld Devices for Streaming Bandwidth Saving
AI总结：
该研究通过主观实验确定手持设备中的感知等效分辨率为720p，超过该分辨率用户无法感知质量提升，从而可显著节省流媒体带宽。
摘要：
我们介绍了为寻找手持设备相关等效分辨率而进行的实验的描述、结果和分析。等效分辨率是指，在手持设备上向用户呈现更高分辨率时，用户不再感知到质量提升的分辨率阈值。因此，只要视频序列未被过度压缩，等效分辨率就是生成和传输视频时值得考虑的最大分辨率。检测等效分辨率可以显著节省带宽消耗。我们使用一组性质各异的视频序列和四款屏幕尺寸范围广泛的手持设备，对五十名受试者进行了主观评估。结果表明，当前手持设备中的等效分辨率为720p，因为用户不认可更高的分辨率。
英文摘要：
We present the description, results, and analysis of the experiments conducted to find the equivalent resolution associated with handheld devices. That is, the resolution from which users stop perceiving quality improvements if better resolutions are presented to them in such devices. Thus, it is the maximum resolution that it is worth considering for generating and delivering video, as long as sequences are not too intensively compressed. Therefore, the detection of the equivalent resolutions allows for notable savings in bandwidth consumption. Subjective assessments have been carried out on fifty subjects using a set of video sequences of very different nature and four handheld devices with a broad range of screen dimensions. The results prove that the equivalent resolution in current handheld devices is 720p as higher resolutions are not valued by users.
