 # gbs-control
 
-This project provides an alternative control software for Tvia Trueview5725 based upscalers / video converter boards.  
-Gbscontrol provides a complete replacement of the original solution, offering many improvements:
+Gbscontrol is an alternative firmware for Tvia Trueview5725 based upscalers / video converter boards.  
+Its growing list of features includes:   
 - very low lag
 - sharp and defined upscaling, comparing well to other -expensive- units
 - no synchronization loss switching 240p/480i (output runs independent from input, sync to display never drops)
