Abstract

Disclosed is an extension of the OS/2* Workplace Shell* environment so that the operating system can cause the playback of multimedia files containing audio data, musical data recorded according to Musical Instrument Digital Interface (MIDI) specifications, and video data. With audio and MIDI files, no additional user interface is presented; with video files, only the video window in which the playback occurs is shown. With this method, the user can quickly view or hear the contents of a multimedia file, without having to use an external application program.

Method for Fast Playback of a Multimedia File

      Disclosed is an extension of the OS/2* Workplace Shell*
environment so that the operating system can cause the playback of
multimedia files containing audio data, musical data recorded
according to Musical Instrument Digital Interface (MIDI)
specifications, and video data.  With audio and MIDI files, no
additional user interface is presented; with video files, only the
video window in which the playback occurs is shown.  With this
method, the user can quickly view or hear the contents of a
multimedia file, without having to use an external application
program.

      Fig. 1 shows the context menu of a multimedia file.  An
extension to the Workplace Shell wpDataFile class adds a "Play"
option to the "Open as" context menu for such a file.  For a
supported multimedia file, this option is the default selection,
indicated by a check mark, which is made if the user double-clicks
the first mouse button on the icon for the file.  When this option is
selected, the entire multimedia file is played from beginning to end,
with the volume level for a multimedia file containing audio being
set at the current "master volume" level of the system.

      Fig. 2 shows the menu which is displayed during playback.  If
the user double-clicks the file icon or otherwise chooses the Open as
Stop alternative, the playback of the file is terminated.
