– Editing Descriptors
Some descriptors can be set to one of several types. We suggest in most cases
that the user not change the descriptor type.
If you do change a descriptor type, it is important to note that the content of the
descriptor does not change, only the way the source treats this data block
changes. Therefore, when changing a descriptor type, make sure to check that the
data after the change still has a meaningful interpretation under the new
descriptor.
Also, several types of descriptors contain compulsory byte values. They must
contain a certain value to maintain correct block structure. As a workflow aid, all
the compulsory bits for the specified descriptor type are displayed in the
Compulsory Byte Value area. The application informs you if their value is valid or
not and if needed, their value can be changed to the recommended ones by
clicking Fix on the window frame.
