Method for Announcing Music Titles on a Compact Disk

      Disclosed is a feature allowing the user of a Compact Disk (CD)
player to listen to an audio announcement providing the title of a
music selection, together with additional information, such as the
name of the singer or musician and the history of the music
selection, before listening to the music itself.

      Table 1 shows the format of a conventional audio CD.  Multiple
tracks are provided, with each track storing a code for the length L,
in time, of a music selection, followed by the music selection M
itself.

      Table 2 shows the format of a first approach for providing the
presently disclosed feature.  Each track includes the music length L,
in time, a header H, additional fields, such as the title T and
additional information I, and the music selection M.  The header
indicates the presence of the additional fields, together with their
lengths.

      A CD player equipped to provide this feature has a capability
of recognizing the header H, together with a programmable capability
to play the title announcement by itself or with the additional
information before playing the music selection.  For example, the
player may have a first button to select the title and a second
button to select the additional information.  The player uses the
field lengths provided in the header, together with the programming
information provided by the buttons, to determine how it should skip
information on the CD.  If neither of these buttons is selected, the
player skips directly to the music selection.

      Tables 3 through 6 show several ways the conventional audio CD
format can be used to provide this feature.  In each case, a length
code is followed by an audio segment, which may be a title,
additional information, or a music selection.  The length code
indicates the length of the audio segment.

      Table 3 shows an example in which the odd-numbered tracks are
used to store titles T, while the even numbered tracks are used to
store music selections M.  In this example, additional information
(in addition to the titles) is not provided.  If the music title
feature is turned off, the player skips the odd track...
