Abstract
A reproducing apparatus configured to reproduce moving image data based on management information including time information and position information about a plurality of intra pictures in the moving image data and display the reproduced moving image data on a display includes a determination unit configured to acquire information about a time interval and a position interval between two intra pictures from the time information and the position information and determine a bit rate between the two intra pictures, and a display control unit configured to display information concerning the bit rate determined by the determination unit, on the display.
Claims16
A reproducing apparatus configured to reproduce moving image data based on management information including time information and position information about a plurality of intra pictures in the moving image data and display the reproduced moving image data on a display, the reproducing apparatus comprising:
- a determination unit configured to acquire information about a time interval and a position interval between two intra pictures from the time information and the position information and determine a bit rate between the two intra pictures, based on the acquired information;
- and
- a processing unit configured to calculate a maximum bit rate from among a plurality of bit rates between two intra pictures determined by the determination unit and store the calculated bit rate as a maximum bit rate of a stream of the moving image data;
- and
- a display control unit configured to display information of the maximum bit rate corresponding to the stream of the moving image data, on the display.
A method for controlling a reproducing apparatus configured to reproduce moving image data based on management information including time information and position information about a plurality of intra pictures in the moving image data and display the reproduced moving image data on a display, the method comprising:
- acquiring information about a time interval and a position interval between two intra pictures from the time information and the position information;
- determining a bit rate between the two intra pictures, based on the acquired information;
- calculating a maximum bit rate from among a plurality of bit rates between two intra pictures determined and storing the calculated bit rate as a maximum bit rate of a stream of the moving image data;
- and
- displaying information of the maximum bit rate corresponding to the stream of the moving image data on the display.
A non-transitory storage medium configured to store a computer-executable program for a method for controlling a reproducing apparatus configured to reproduce moving image data based on management information including time information and position information about a plurality of intra pictures in the moving image data and display the reproduced moving image data on a display, the method comprising:
- acquiring information about a time interval and a position interval between two intra pictures from the time information and the position information;
- determining a bit rate between the two intra pictures, based on the acquired information;
- calculating a maximum bit rate from among a plurality of bit rates between two intra pictures determined and storing the calculated bit rate as a maximum bit rate of a stream of the moving image data;
- and
- displaying information of the maximum bit rate corresponding to the stream of the moving image data on the display.
A reproducing apparatus configured to reproduce moving image data and display the reproduced moving image data on a display, the reproducing apparatus comprising:
- a reading unit configured to read bit rate information or recording mode information concerning the moving image data from management information of the moving image data if an apparatus which generates the moving image data and the reproducing apparatus is a same apparatus;
- and
- a display control unit configured to display the bit rate information or the recording mode information concerning the moving image data in a different display manner between when the apparatus that generates the moving image data and the reproducing apparatus are the same apparatus and when the apparatus that generates the moving image data and the reproducing apparatus are not the same apparatus,
- wherein, when the apparatus that generates the moving image data and the reproducing apparatus are not the same apparatus, the display control unit displays a maximum bit rate calculated from among a plurality of bit rates between two intra pictures in the moving image data, each of the plurality of bit rates determined based on a time interval and position interval between two intra pictures.
