A digital broadcasting system provides a method and device for packetizing a video stream. The packetizing device includes: a video frame check block for classifying an encoded video stream according to the frame type; a header setting block for setting a packet header for each of the classified frames; and a packetizing block for packetizing a video frame on the basis of the set packet header. The frame type may be one of an intra-coded (I) frame, a predicted (P) frame, and a bi-predictive (B) frame. Since a digital broadcasting stream is efficiently packetized, overhead due to a typical synchronization packet may be reduced, and accordingly, bandwidth may be efficiently used.
