<p>A playback apparatus of the invention comprises reading means (410) for reading an information stream (S0) from a record carrier (1) and demultiplexing means (430) for separating at least a first and a second sub-stream (S1, S2) from the information stream (S0), which first sub-stream (S1) comprises encoded video data and which second sub-stream (S2) comprises graphics data. The apparatus further comprises first decoding means (441) for decoding the first sub-stream (S1) and second decoding means (480) for receiving the second sub-stream (S2) and for decoding graphics data encoded according to a first format (DVD Video sub-picture format). The apparatus further comprises combining means (457) for combining the decoded video stream (S11) and the decoded graphics data (S21). The apparatus is characterized by converting means (450) for receiving a second sub-stream (S2) of graphics data encoded according to a second format (SVCD OGT-format) and characterized by selecting means (470) for selecting the converted graphics data or the data according to the first format from the second stream as input data for the second decoding means.</p> |
