A method of processing EPG (Electronic Program Guide) metadata in a network device includes performing a service discovery procedure utilizing multiple service discovery metadata components supplied by a service provider, receiving EPG metadata corresponding to a super group information element comprising both of a member element giving a group ID of another super group information element that has a higher level than a level of the super group information element and a level attribute giving a level of super group represented by the super group information element, wherein the member element is used to reference the other super group information element at a higher level, and processing the EPG metadata.

Disclosed is a speed-change playback apparatus of a digital TV which performs better fast forward and backward performances by analyzing a transport stream inputted at the time of a time shift service and a method thereof. An MPEG decoder detects I picture location information in a TP packet by analyzing a TP packet inputted at the time of a time shift service, and a time shift software module extracts a TP packet constituting the I picture from the stored TP packets by the detected I picture location information and feeds to the MPEG decoder. Therefore, fast forward and fast backward performances can be efficiently performed by adding a simple logic which analyzes the TP packet to the MPEG decoder.
