Abstract:
1. A digital broadcast receiving apparatus comprising: a transport stream generator to generate a transport stream from a digital broadcast signal; a transport stream buffer to buffer the transport stream; a controller to determine whether the buffered transport stream is reliable; a transport stream processor to search for interpretation information for interpreting broadcast content from the buffered transport stream, and to search for the broadcast content based on the interpretation information, if the buffered transport stream is determined as reliable; and an audio and video processor to process the searched broadcast content, wherein the transport stream buffer has a capacity greater than a value obtained by adding a maximum value of the intervals for which a Program Association Table (PAT) is repeatedly received, a maximum value of the intervals for which a Program Map Table (PMT) is repeatedly received, and a maximum value of the intervals for which an Object Descriptor (OD) is repeatedly received, and multiplying the added result by a data transmission rate of a broadcast service.
