Playback apparatus, broadcast receiving device, and computer-readable recording medium
A television broadcast received by a television broadcast receiving device is recorded as a recording file, and a central control device identifies specific recording portions (for example, commercial portions) within the recording file, and then calculates the remaining playback time (the total remaining time without the specific recording portions) that is the playback time of the recording file after the playback position minus the total time for the specific recording portions after the playback position, and displays information according to the total remaining time without the specific recording portions.
1 . A playback apparatus comprising:
recording means storing a file to which identification information is assigned;
acquisition means for acquiring a playback time needed for playing back every part, except for a part having a predetermined content, of a content contained in the file stored in the recording means; and
display means for displaying, in a pair with the identification information, the playback time needed for playing back every part, except for the part having the predetermined content, of the content.
2 . The playback apparatus according to claim 1 , further comprising specifying means for specifying the predetermined part of the content contained in the file, wherein
the acquisition means acquires a difference between a playback time needed for playing back every part of the content contained in the file and a time needed for playing back the part specified by the specifying means.
3 . The playback apparatus according to claim 1 , further comprising specifying means for specifying the predetermined part of the contents contained in the file, wherein
the acquisition means acquires a difference between a playback time needed for playing back every part of the content contained in the file and a sum of playback times needed for playing back the parts specified by the specifying means.
4 . The playback apparatus according to claim 1 , wherein
when a plurality of files are recorded in the recording means,
the acquisition means acquires, for each of the plurality of files, a playback time needed for playing back every part, except for a part having a predetermined content, of the content of the file;
the display means displays, as a list, the acquired playback times needed for playing back every part, except for a part having a predetermined content, of the respective contents of the files and the respective identification information of the plurality of files so that each identification information is paired with the respective acquired playback time.
5 . The playback apparatus according to claim 1 , further comprising playback means for playing back every part, except for a part having a predetermined content, of a file stored in the recording means; wherein
the acquisition means acquires a first remaining playback time, remaining in playing back every part from a position being played back to the end of the content contained in the file, and a second remaining playback time, remaining in playing back every part, except for a part having a predetermined content, from the position being played back to the end of the contents contained in the file; and
the display means displays the first remaining playback time and the second remaining playback time.
6 . The playback apparatus according to claim 5 , further comprising specifying means for: (i) specifying the part having the predetermined content, of the content contained in the file, and (ii) storing a starting position and an end position of the part having the predetermined contents, in such a way as to be associated with the file, wherein
the acquisition means acquires the second remaining playback time, based on the starting and end positions of the part having the predetermined contents, during the playback of the content contained in the file, the playback being performed by the playback means.
7 . The playback apparatus according to claim 1 , wherein the display means displays a mark indicating the playback time, acquired by the acquisition means, of the content.
8 . A broadcast receiving device comprising:
a playback apparatus as recited in claim 1 ;
receiving means for receiving broadcast; and
recording a file containing a content of the received broadcast to the recording means.
9 . A computer-readable recording medium having recorded thereon a program to cause a computer, including recording means storing a file to which identification information is assigned, to execute the processes of:
acquiring a playback time needed for playing back every part, except for a part having a predetermined content, of a content contained in the file stored in the recording means; and
displaying, in a pair with the identification information, the playback time needed for playing back every part, except for the part having the predetermined content, of the contents.
