Table 3 Algorithm 1: frequency of switching events as a decision factor in DASH quality adaptation algorithm

From: The impact of video-quality-level switching on user quality of experience in dynamic adaptive streaming over HTTP

Line Statement
1 Fs < = frequency of switching events
2 VQLn < = Current Video Quality Level
3 DASH_Out < = Output of DASH algorithm (SU, SD or same video quality)
4 if (DASH_Out = SD) then
5 VQL n = VQL n-1
6 if (Fs< ½ & DASH_Out = SU) then
7 VQL n = VQL n+1
8 Else
9 VQL n = VQL n
10 end if
