Abstract:
1. A stream analysis apparatus comprising: packet header extracting means for extracting header information from a transport stream packet; time stamp extracting means for extracting a time stamp from the transport stream packet; clock generation process means for generating a clock signal as a reference of presentation timing of content data transmitted by the transport stream packet; and analysis process means for analyzing an access unit transmitted by the transport stream packet using a PCR (Program Clock Reference) extracted by the packet header extracting means, the clock and the time stamp wherein the analysis process means generates a display signal for displaying an analysis result having a box indicator representing the access unit on a coordinate plane of which axes are elapsed time and PCR time calculated using the PCR with one pair of the opposing sides of the box indicator indicating the first and last data arrival time of the access unit respectively and one side of another pair of the opposing sides of the box indicator indicating PTS (Presentation Time Stamp) of the access unit.
