Modify NVDS Parameters
Users can modify both the USER Parameters and ROM Parameters.
ROM Parameters: You can modify the Parameter Name, Description, and Value of a ROM parameter. The modification on a parameter value does not lead to changes in the parameter length (except varying-length character strings).
USER Parameters: For user parameters in same and different states, the Parameter Name, Description, and Value can be modified. For user parameters in unfinished state, the Type and Length(Byte) can be modified.
Double-click a parameter to be modified, and edit the parameter information in the pop-up window. Click OK to write the modifications into NVDS.

Parameters in unfinished state with a modified length that is different from that in the NVDS remain unfinished. Such parameters cannot be automatically written into the NVDS.
