  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.
