Abstract
An MPEG recording and playback device is provided which can provide pertinent information on a program being played back to viewers at least in certain forms with certainty, thereby facilitating viewers' convenience. In this MPEG recording and playback device, during recording of MPEG data, a program information collecting unit (14) collects pertinent information on program responsive to an input path of the MPEG data by changing a method of collection, and the pertinent information on program is recorded in a different location of a track from that for the MPEG data. During playback, recorded pertinent information on program is outputted after being superimposed on an MPEG decoded analog image signal.
