ARD DISK CAPTURING CAPACITY DATA
 
The maximum amount of digital video and audio data that can be stored is 
dependent upon the data rate at which the television stations transmit their 
signals. This data rate is not the same for all stations.  
Some stations use the static multiplex system, which means that the picture 
information is only coded with the data rate that is actually necessary. Other 
stations currently use constant data rates.  
For this reason, it is not possible to give a fixed conversion formula here for 
the relationship between the size of the hard disk and the possible capturing 
capacity.  
It is generally true to say that the better the picture quality and the higher the 
data rate, the fewer programs will fit on the hard disk. One and the same 
film captured from different stations can therefore take up different amounts 
of space on the hard disk.  
The following table gives you an indication of the possible capture 
durations for different sizes of hard disk depending on the transmitted data 
rate:  
 
Hard disk capacity 
Capture duration at a 
constant data rate of 
5 Mbit/s 
Capture duration at a 
constant data rate of
3 Mbit/s
