Abstract: A method of processing EPG metadata in a network device includes performing a services discovery procedure utilizing multiple service discovery metadata components supplied by a service provider, and requesting specific SGDDs (service guide delivery descriptors) or specific fragments.

Abstract: 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.

Abstract: 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.

Abstract: A method for marking a label of an external AV apparatus of the present invention includes displaying an external AV signal outputted from the external AV apparatus of the plurality of external AV apparatuses, and setting and displaying one label of an external AV signal using a label setting signal including a plurality of labels stored beforehand. Accordingly, a user can easily select and watch an external AV signal of the desired external AV apparatus through the label of the external AV apparatus.

Abstract: A synchronous DRAM and method are provided in which main cells and spare cells are accessed by an external address during automatic refresh of a test mode. In the synchronous DRAM, a mode register setting circuit receives an external signal in response to a plurality of control signals to generate a mode register setting signal, during an automatic refresh operation in a test mode. An address selector selects and outputs an external address to the memory cell array, in response to the activation of the mode register set signal, during the automatic refresh operation in the test mode. The address selector selects and outputs an internal address to the memory cell array, in response to the deactivation of the mode register set signal, during an automatic refresh operation in a normal mode. Therefore, the main cells and the spare cells in the memory cell array are sequentially accessed and refreshed by the external address during the automatic refresh operation in the test mode.
