An analysis display has a coordinate plane of which coordinate axes are elapsed time and PCR (Program Clock Reference) time calculated using PCR extracted from header information of a transport stream packet. A box indicator representing an access unit is provided on the coordinate plane and sides of the box indicator indicate an arrival time of the access unit AU and time of time stamps PTS/DTS. It analyzes the PCR in a transport stream layer and the time stamps PTS/DTS in a PES layer in a manner of over layers, and displays an analysis result that allows easily understanding a relationship between system timing and them. Therefore, it makes it easier to check a problem on the PCR and the time stamps PTS/DTS.
