The PVR backend (as the server side part), which directly communicates with a TV tuner adapter(s) to receive the Live TV signals and create a video or audio stream, and also record to files.
1. Convert time between hour, minute, second, or day with conversion factor. As we known, 1 hour = 60 minutes = 3600 seconds =1/24 day. So we can convert the time measurement with multiplying these factors. Convert between hours to seconds:
Days are converted to hours, by multiplying the days by the conversion factor as 24. The conversion can be reversed by dividing, the hours, by 24 to get days; however, the reciprocal 1/24 could be considered the reverse conversion factor for an hours-to-days conversion, where 1/24 ~= 0.0416666666667.
