(detaillog)
A student may watch a video during the progress check (attendance) period and the progress check (attendance) period may pass.
In this case, only the time watched within the period is recognized as learning time.
In detaillog, 'state 5' is a record that is recorded separately to check the time recognized as attendance if there is a time from attendance to absence within the episode where you watched the video.
EX.
The student played a total of 2 minutes and 42 seconds, but only 53 seconds were recognized because the time learned within the actual progress check (attendance) period was 53 seconds.
