`[57]
`A multi-media footnote control links a reference and a
`video. During the viewing of a video by an author/edi
`tor thereof, a footnote may be added to properly credit
`another source and to aid in study of the subject pres
`ented on the video. At the appropriate place in the
`video, the author/editor stops the video and displays a
`create footnote window. The author will then enter the
`appropriate data into the window. The footnote data
`will then be automatically passed to the video in the
`predetermined position. The footnote will be displayed
`in a footnote area during the running of the video. If a
`user/author of the video wishes to review the footnoted
`reference, the video may be stopped and by indicating
`the footnote such as with a mouse, the reference will be
`displayed in a separate window.

`
`TECHNICAL FIELD OF THE INVENTION
`The present invention relates in general to computer
`25
`software, and in particular to a method and apparatus
`for creating multi-media footnotes in video.
`
`30
`
`BACKGROUND OF THE INVENTION
`With the advent of multi-media computer systems,
`video has become an increasingly popular technique for
`creating and presenting professional works. While writ
`ten published works allow the reader to enhance under
`standing of the material through the use of footnotes,
`there currently is no way to create multi-media enabled
`footnotes in on-line full-motion video ?les. Currently,
`the only known way to indicate credits in a full-motion
`video is the standard listing of credits either at the end
`of the video or in some intermediate position. However,
`these credits are not linked to any source document and
`40
`it is not possible to call-up and view the source docu
`ments on-line. Thus, there is a need for a method and
`apparatus which allows the insertion of footnotes in
`video and the ability to call-up and view the footnoted
`source material.
`
`45
`
`SUMMARY OF THE INVENTION
`The present invention provides a method and appara
`tus for creating a multi-media footnote control in video
`data which substantially eliminates or reduces the prob
`lems of the prior art. The present invention provides
`enhanced research capability to the use of multi-media
`programming.
`In accordance with one aspect of the present inven
`tion, a method of creating a multi-media footnote con
`trol in video data on-line in a computer system is pro
`vided. The video and the reference are ?rst linked.
`Footnote data is then entered by any appropriate man
`ner in a create footnote window. The data is then auto
`matically passed to the video and positioned in a prede
`termined area of the video. The footnote thus created
`will be displayed at a predetermined time for a predeter
`mined length of time when the video is subsequently
`run. By clicking on the created footnote, the reference
`material will be displayed for separate review.
`It is a technical advantage of the present invention
`that footnotes may be added to video data to enhance a
`user’s understanding thereof. It is a further technical
`
`55
`
`65
`
`1
`
`5,440,678

`advantage that the footnoted reference may be called
`up for review by the user.

`
`DETAILED DESCRIPTION OF THE
`INVENTION
`Referring to FIG. 1, there is depicted a graphical
`representation of a data processing system 8, which may
`be utilized to implement the present invention. As may
`be seen, the data processing system 8 may include a
`plurality of networks, such as Local Area Networks
`(LAN) 10 and 32, each of which preferably includes a
`plurality of individual computers 12 and 30, respec
`tively. Of course, those skilled in the art will appreciate
`that a plurality of Intelligent Work Stations (IWS) cou
`pled to a host processor may be utilized for each such
`network. As is common in such data processing sys
`tems, each individual computer may be coupled to a
`storage device 14 and/ or a printer/output device 16.
`The data processing system 8 may also include multi
`ple mainframe computers, such as mainframe computer
`18, which may be preferably coupled to LAN 10 by
`means of communications link 22. The mainframe com
`puter 18 may also be coupled to a storage device 20
`which may serve as remote storage for LAN 10. Simi
`larly, LAN 10 may be coupled via communications link
`24 through a subsystem control unit/communications
`controller 26 and communications link 34 to a gateway
`server 28. Gateway server 28 is preferably an individual
`computer or IWS which serves to link LAN 32 to LAN
`10. As discussed above with respect to LAN 32 and
`LAN 10, a plurality of documents or resource objects
`may be stored within storage device 20 and controlled
`by mainframe computer 18, as resource manager or
`library service for the resource objects thus stored. Of
`course those skilled in the art will appreciate that main
`frame computer 18 may be located a great geographic
`distance from LAN 10 and similarly LAN 10 may be
`located a substantial distance from LAN 32. For exam
`ple, LAN 32 may be located in California while LAN
`10 may be located within Texas and mainframe com
`puter 18 may be located in New York.
`Referring to FIG. 2, a graphical representation of the
`present invention as viewed by an end user is shown.
`The end user views a multimedia presentation in a win
`dow 41 on a screen 40, such as is found on the individual
`computers 12 and 30 (see FIG. 1). The window 41 is
`divided into a video area 42, a footnote area 44, and a
`control area 46. While the video in the video area 42
`runs, any material that is footnoted is indicated by foot
`
`APPLE 1005 - Page 7
`
`

`
`20
`
`25
`
`35
`
`5,440,678
`3
`note numerals 1, 2, and 3, as indicated by reference
`numeral 48 in the footnote area 44. Controls are pro
`vided in the control area 46 for use by an end user to
`control the viewing of the video in the video area 42.
`For example, a start/ resume button 50 and a stop button
`52 may be provided. Thus, while viewing the video, an
`end user may be presented with the footnote 1, 2, or 3 as
`indicated by reference numeral 48 in the footnote area
`44. The end user could then activate the stop push-but
`ton 52 which would stop the video. The end user could
`then activate any of the footnotes 48 by any appropriate
`method such as clicking on them with a mouse, and be
`presented with a screen (not shown in FIG. 2) that
`would display the reference material therein. It is to be
`understood that the reference material may comprise a
`written document, video, audio or any combination
`thereof.
`Referring to FIG. 3, the window 41 is shown with the
`footnote development of the present invention dis
`played thereon. When an author/ user wants to create or
`edit footnotes in a video, the video is shown in the video
`area 42 with a footnote create/edit area 60 and a con
`trol/ create area 62.
`The control/ create area 62 comprises a control area
`64 and a create area 66. For example, the control area 64
`contains a start/ resume button 68, a stop button 70 and
`a reverse button 72. The create area 66 contains, for
`example, a footnote create/change button 73 and a
`delete footnote button 74. The footnote creation area 60
`contains existing footnote 76 and additional space for
`the insertion of additional footnotes.
`While viewing a video in the video area 42, an au
`thor/user may want to insert/edit a footnote for a spe
`ci?c portion thereof. The end user would stop the video
`by depressing the stop push-button '70 (and then revers
`ing the video by depressing reverse push-button 72, if
`necessary) and then depress either the footnote create/
`change push-button 73 or the delete footnote push-but
`ton 74. To delete a footnote, the author/user would
`place a cursor over the existing footnote and then de
`40
`press the delete footnote push-button 74. To create/
`change a footnote, the author would depress the foot
`note create/ change push-button 73.
`By depressing push-button 73, a create footnote win
`dow 80 (see FIG. 4) would appear. If an existing foot
`45
`note such as the existing footnote 76 (see FIG. 3) were
`to be edited, the appropriate information regarding
`footnote 76 would appear in the create footnote win
`dow 80 as a result of the cursor being placed over foot
`note 76. The author would then be able to edit the
`information as desired in the window 80. However, if a
`new footnote is to be created, the create footnote win
`dow 80 would appear with blanks in each data area. The
`author would then fill in the blanks as required using
`any appropriate method, such as keying in or dragging
`the data, and enter the information to create the new
`footnote. The create footnote window 80 may contain
`such information, for example, as the duration the foot
`note is to be available, when the footnote will appear,
`and multi-media reference information such as docu
`ment name, author, page, and, etc. As previously stated
`above, once the author has the appropriate information
`within the blanks in window 80, it is necessary to enter
`the information to create the new footnote.
`Referring to FIG. 5, a ?owchart of the present inven
`65
`tion is illustrated for the start-up sequence thereof. At
`block 90, a footnote table is read. A footnote table (not
`shown) must be created during the development stage
`
`4
`of the present invention, as will be subsequently de
`scribed in greater detail (see FIG. 10). At block 92, the
`footnote portion of the screen is drawn. At decision
`block 94, it is determined whether or not any footnotes
`are present at the start of the video. If the response to
`decision block 94 is yes, the required footnotes are
`drawn in the indicated area at block 96. The footnotes
`are drawn in the indicated area based upon space within
`the footnote area. For example, the ?rst footnote may
`be presented in the upper left-hand corner of the foot
`note area and subsequent footnotes can be added in any
`prescribed manner. At block 98, a timer is set according
`to the footnote table for removal of the footnotes. If the
`response to decision block 94 is no and/ or subsequent to
`block 98, a timer is set for the next footnote in accor
`dance with the footnote table at block 100. At block
`102, a message is sent to start the video. The present
`invention then waits at 104.
`Referring to FIG. 6, the flow of the present invention
`during the viewing of a video is illustrated. At block
`110, a footnote timer is interrupted. At block 112, the
`appropriate footnotes are found in the footnote table. At
`decision block 114 it is determined whether to draw or
`remove a footnote. If the response to decision block 114
`is remove, the footnote is removed from the screen at
`block 116. It is then determined at decision block 118
`whether or not the timer is set for the next footnote. If
`the response to decision block 118 is yes, the present
`invention waits at 120. If the response to decision block
`118 is no, a timer is set for the next footnote at block 122
`followed by waiting at 120. If the response to decision
`block 114 is draw, the footnote is drawn in the desired
`location at block 124. All footnotes are automatically
`positioned and/or repositioned based upon the number
`of footnotes present and their order of appearance. A
`timer is then set to remove the footnote at block 126
`followed by waiting at 120.
`Referring next to FIG. 7, the flow of the present
`invention is illustrated in the case in which a user wants
`to see a footnote reference displayed. At block 130, the
`user clicks a mouse button over the footnote. At block
`132, a message is sent to stop the video and the timers.
`At block 134 the footnote reference data is passed to the
`multi-media system which opens the reference and
`shows it to the viewer. The reference can be left on or
`closed when the viewer is finished with a review
`thereof. The present invention then waits at 136.
`Referring to FIG. 8, the flow of the present invention
`after having stopped the video for any reason is illus
`trated. At block 140, the user clicks the mouse over the
`resume button. At block 142, the footnote timers that
`were stopped are reset. At block 144, a message is sent
`to resume the video and the present invention waits at
`146.
`Referring to FIG. 9, the flow of the present invention
`is illustrated for development of a footnote. At block
`150, the user clicks the mouse on a control area button.
`At decision block 152 it is determined which button was
`pressed. If the start/resume button was pressed, timer
`information is saved at block 154. A message is then sent
`to start the video at block 156. The present invention
`then waits at 158.
`If it is determined at decision block 152 that the stop
`push-button was pressed, timer information is saved at
`block 160. It is then determined at decision block 162
`whether or not the reverse switch had been depressed
`previously (i.e. was the video going forward or in re
`verse). If the response to decision block 162 is no, a

`and multi-media reference material pertinent
`message is sent to stop the video at block 164. If the
`response to decision block 162 is yes, the reverse switch
`thereto which is stored in a separate on-line source;
`is turned off at block 166. At block 168, relative timer
`entering identi?cation data from said multi-media
`information is calculated and saved. A message is then
