One solution of EPG data propagation on digital television set-top box

This paper presents one solution of EPG (Electronic Program Guide) data propagation in DTV set-top box. Propagation is based on a existing solution and extensive process optimization has been done. Optimization reflects in lesser memory consumption and in lesser time consumption in propagating EPG data in contrary to the original state. The result is faster access to the requested data and faster presentation of the data to the end user on the television screen.
