Abstract
If a movie reproducing apparatus detects an error during reproduction of encoded movie data, based on management information that includes a recording position of an intra-picture coded picture included in the encoded movie data, the movie reproducing apparatus determines a position used when the error is recovered by searching for an intra-picture coded picture subsequent to a frame including data with the error as well as updates elapsed time information to be displayed based on a frame number of the searched intra-picture coded picture at the time the error is recovered.
Claims19
A movie reproducing apparatus for reproducing encoded movie data that does not include time stamp information, the apparatus comprising:
- a reproduction unit configured to reproduce the encoded movie data from a storage medium wherein the encoded movie data contains an intra-picture coded picture and an inter-coded picture;
- a decoding unit configured to decode data reproduced by the reproduction unit;
- a display unit configured to display a moving image of the movie data and elapsed time information of the moving image based on the movie data decoded by the decoding unit;
- wherein if an error of the movie data occurs while the reproduction unit is reproducing the movie data,
- the display unit, in response to a recovery of the error of the movie data, updates elapsed time information to be displayed based on information of an intra-picture coded picture of the movie data.
A movie reproducing apparatus for reproducing encoded movie data that does not include time stamp information, the apparatus comprising:
- a reproduction unit configured to reproduce the encoded movie data from a storage medium wherein the encoded movie data contains an intra-picture coded picture and an inter-picture coded picture;
- a decoding unit configured to decode the movie data reproduced by the reproduction unit;
- and
- a display unit, if an error of the movie data occurs while reproducing the movie data, configured to display displays error information that includes a period of a frame dropped caused by the error or a number of dropped frames caused by the error, in response to a recovery of the error of the movie data.
A movie reproducing method for reproducing encoded movie data that does not include time stamp information, the method comprising:
- reproducing the encoded movie data from a storage medium wherein the encoded movie data contains an intra-picture coded picture and an inter-picture coded picture;
- decoding the movie data reproduced;
- and
- displaying a moving image of the movie data and elapsed time information of the moving image based on the movie data decoded;
- wherein if an error of the movie data occurs while the reproduction unit is reproducing the movie data, displaying, in response to a recovery of the error of the movie data, updates elapsed time information to be displayed based on information of an intra-picture coded picture of the movie data.
A movie reproducing method for reproducing encoded movie data that does not include time stamp information, the method comprising:
- reproducing the encoded movie data from a storage medium wherein the encoded movie data contains an intra-picture coded picture and an inter-picture coded picture;
- decoding the movie data reproduced;
- and
- if an error of the movie data occurs while reproducing the movie data, displaying error information that includes a period of a frame dropped caused by the error or a number of dropped frames caused by the error.
