employed in the viewer management method according to
the present embodiment, programs and data for dynamically
generating passwords and acquisition codes are also pre
stored in a prescribed area thereof. Special processing to be
performed in this kind of DVD media M may be conducted
with the authoring process during the manufacture of the
DVD media.
[0036] Foremost, as shown in FIG. 1, when the viewer
inserts the DVD media M into the DVD player 11, the DVD
player 11 reads the disc control information recorded on the
DVD media M, and displays the activation menu screen
according to such disc control information on the display
device 12 ((1) in FIG. 1). This activation menu screen is
constituted including with menu items for the media pro
vider to request authentication to the viewer regarding the
erable that a ?ag to such effect is stored in the internal

upon reproducing a speci?ed content recorded on a DVD
media M, the viewer uses the mobile telephone 13 to access
the server computer 2 on the Internet and acquire the
password with the acquisition code shown on the ?rst viewer
authentication screen, and is urged to input such password.
Thus, even if it is a stand-along DVD player 11 that does not
have a network connection function, it is possible to manage
the viewing of contents.
[0042] FIG. 2 is a ?owchart for explaining the operation
?ow of the DVD player 11 according to the present embodi

sequentially for the sake of convenience below, this is not
limited thereto. Therefore, so as long as there is no contra
diction with the operation, the processing order may be
rearranged or performed in parallel.
[0043] In FIG. 2, when the viewer loads the DVD media
M into the disc tray of the DVD player 11, the DVD player
11 loads the DVD media M in its internal disc reproduction
mechanism, reads the disc control information (STEP 201),

the password table, and judges whether the two passwords
coincide (STEP 206). When the DVD player 11 judges that
the password input from the viewer coincides with the
password registered in the password table; that is, when it
judges that the input password is valid, a ?ag showing the
success of authentication is stored in the internal memory
buffer, and the reproduction of the content is started accord
ing to the disc control information (STEP 207). As a result,
the viewer will be able to view the viewing management
target content that he/ she wished to view. Here, it is pref
erable that the ?ag showing the success of authentication is
stored in the internal memory buffer for each content since
viewing will be managed for each viewing management
target content.
[0051] Incidentally, when the DVD player 11 judges that
the input password is not valid, it performs prescribed error
processing (STEP 208), and compulsorily ends the process
it performs prescribed error processing and ends the routine
(STEP 610).
[0055] FIG. 8 is a diagram showing an example of the
acquisition code input screen according to the present
embodiment. An acquisition code input ?eld for inputting,
for example, a 12 digit number is provided to the acquisition
code input screen. When the viewer inputs the acquisition
code in the acquisition code input ?eld of the acquisition
code input screen while referring to the ?rst viewer authen
tication screen displayed with the DVD player 11 and selects
the OK button, the mobile telephone 13 transmits the input
contents to the server computer 2. When the server computer
2 receives an acquisition code from an authenticated mobile
telephone 13, it refers to the viewing management database
system, speci?es the contents and viewing conditions (view
ing period, price, etc.) of the viewing management target
content corresponding to such acquisition code, and displays
on the display unit of the mobile telephone 13 the viewing
