Directors salary & directors remunaration

Sir, 

Accroding to Service tax point of view what is the difference between

Salary paid to the Directors, Remuneration paid to the Dirctors.

How can we make out , in a company balance sheet whether

salary is paid or remunaration is paid when it is accounted under the

heading  Directors remunaration.

Kindly clarify.

with regards,

mala
