As discussed above, in one embodiment, the corresponding e-mark display panel 204a, 204b may be configured to display time and/or date information of the user's input operation of e-mark button 203.
At step 430, music marker device 110 determines whether all available e-mark display panels 204a, 204b are being used (for example, illuminated or flashing in response to user's input operation of e-mark button 203). If it is determined that there are e-mark display panels 204a, 204b available, music marker device 110 waits for further input operation by the user at step 410. On the other hand, if it is determined at step 430 that all available e-mark display panels 204a, 204b are in use, then at step 440, electronic music marker device 110 generates an output signal to inform the user that music marker device 110 has reached its maximum number of e-marks that it can handle, and the procedure ends. In one embodiment, the output signal from music marker device 110 to inform the user that it has reached its maximum number of e-marks it can handle may be an audible output signal such as an audible tone via an audio output terminal (not shown). Alternatively, music marker device 100 may be configured to flash all e-mark display panels 203 simultaneously for a predetermined period of time to visually indicate to the user that it has reached its maximum number of e-marks that it can handle.
FIG. 5 is a flowchart for illustrating one embodiment of downloading data from the user's electronic music marker device account to the music marker device. Referring to FIG. 5, at step 510, music marker device 110 detects a connection to gateway terminal 130 connected to the internet. After the user enters the user's account information and performing necessary electronic music marker device account access steps at gateway terminal 130, at step 520, data corresponding to the e-marks (bookmarks) stored in music marker device 110 is transmitted to the user's electronic music marker device account via gateway terminal 130, and in response, the corresponding text and/or image (including video) data are retrieved from server terminal 140 of e-marker.com web site and transmitted to the user's electronic music marker device account. Then, at step 530, the text and/or image data corresponding to each e-marks are downloaded onto music marker device 110. At step 540, the downloaded text and/or image data are displayed on each corresponding e-mark display panel 204a, 204b on music marker device 110.
When the user disconnects music marker device 110 from gateway terminal 130, the termination of the is detected at step 550, and at step 560, music marker device 110 is reset such that previously stored e-marks inputted by the user may be erased from the storage unit of music marker device 110, and correspondingly, the illuminated e-mark display panels 204a, 204b are turned off. The user may then operate e-mark button 203 again to input additional bookmarks of music clip broadcasts from registered radio and television broadcast stations.
FIG. 6 is a database illustration of a user account stored in the storage unit of the server terminal in accordance with one embodiment. Referring to FIG. 6, user account database 600 includes user name field 610, user marker ID field 620, user account name field 630, location ID field 640, and feed type field 650. As can be seen, user name field 610 is configured to store the name of each registered user of music marker device 110, while marker ID field 620 is configured to store the corresponding unique marker identification code for each registered user. Additionally, user account name field 630 is configured to store a corresponding user account name generated by server terminal 140 upon user registration process at e-marker.com web site, or alternatively, provided to server terminal 140 by the user via input unit 131 of gateway terminal 130 during registration process.
Referring back to FIG. 6, location ID field of user account database 600 is configured to store a location identification code for each respective registered user, while feed type field 650 is configured to store the type of data feed (for example, a ten-minute data feed or a next day data feed) assigned to the respective location corresponding to each registered user. For example, registered user John first whose music marker device has marker ID “A11-K21-K43-F23” and whose e-marker.com account user name is “FirstJ” is registered in the San Francisco, Calif., as can be seen from the corresponding entry in location ID field 640 for John First. Moreover, it can be seen from user account database 600 that San Francisco is configured with a 10-minute feed type. On the other hand, user Jack Green located in Vail, Colo., is configured with a next-day feed type data transmission.
As will be discussed in further detail below, depending upon the feed type assigned for each geographic location, playlist provider 150 is configured to transmit information corresponding to broadcast music clips to server terminal 140 for transmission to the users via gateway terminal 130 within the assigned time frame (for example, within 10 minutes of broadcast in geographic location such as San Francisco, Calif., or alternatively, within a predetermined time frame (next-day feed type) for geographic location such as Vail, Colo.
FIG. 7 is a database illustration of user bookmarks stored in the storage unit of the server terminal in accordance with one embodiment. As discussed above, when the user connects music marker device 110 to gateway terminal 130 via connection 120, a connection with server terminal 140 is established by accessing the user's e-marker.com account via gateway terminal 130. Referring to FIG. 7, as can be seen, user bookmark database 700 corresponds to user Matt Sawyer located in Atlanta, Ga., with marker ID “K01-U-23-N45-I67” who has bookmarked six music clips broadcast over two different radio stations, in particular, radio stations with call letters KROK and KCGO.
In one aspect, user bookmark database 700 for each user may be generated and stored in storage unit 144 of server terminal 140 under the control of controller 145. In particular, when the user connects to server terminal 140 and transmits entered bookmarks and the device ID via gateway terminal 130, controller 145 of server terminal 140 may be configured to access the user account database 600 to retrieve account information corresponding to the user based on the received device ID, and determine the user's location and the type of feed transmission. By comparing the received bookmark date and time stamps with playlist data received from playlist provider 150, and based on the determined location and feed type for the user's bookmarks, controller 140 may be configured to determine the information corresponding to the user's each entered bookmark, such as the name of the bookmarked music clip, the name of the artist, and the name of the album. When controller 145 of server terminal 140 has completed generating user bookmark database 700 based on playlist information received from playlist provider 150 and the bookmarks received from the user, server terminal 140 may be configured to transmit information corresponding to the bookmarked music clips to the user's account for access by the user through gateway terminal 130.
FIGS. 8–9 are database illustrations of broadcast transmissions stored in the storage unit of the playlist provider in accordance with one embodiment. Referring to FIGS. 8–9, broadcast database 800 for radio station KROK in Atlanta, Ga., includes broadcast time field 810, title field 820, artist field 830 and album field 840, and similarly, broadcast database 900 for radio station KCGO in Atlanta includes broadcast time field 910, title field 920, artist field 930 and album field 940. As shown, broadcast time fields 810, 910 are configured to store the beginning time for each broadcast from the respective radio stations, title field 820, 920 are configured to store the title of the music clip broadcast at the corresponding broadcast time, and artist fields 830, 930 and album fields 840, 940 are respectively configured to store the corresponding name of the artist and the album for the broadcast music clip.
Since Atlanta, Ga. is assigned with a 10-minute feed type transmission, after ten minutes from the conclusion of each music clip broadcast from the registered radio stations in Atlanta, for example, radio station with call letter KROK, playlist provider 150 is configured to transmit the information corresponding to the broadcast music clip to server terminal 140 retrieved from 10-minute feed database 151.
For example, user's first bookmark marked on Jan. 21, 2001 at 1:46 PM (FIG. 3) corresponds to broadcast of a song titled “Fade to Black” broadcast from radio station with call letter KROK (FIG. 7) whose broadcast began at 1:45 PM (FIG. 8). It can be seen that the broadcast of the song “Fade to Black” from the radio station with call letter KROK terminated at approximately 1:52 PM. Thus, playlist provider 150 may be configured to retrieve information corresponding to the broadcast song “Fade to Black” such as the name of the artist (Metallica) and the corresponding album (Ride the Lightning) from 10-minute feed database 151 and transmit the retrieved information to server terminal 140 at approximately 1:52 PM. Accordingly, when the user connects music marker device 110 to access the user's e-marker.com account after bookmarking the various broadcast music clips, the user will obtain information corresponding to the bookmarked music clip received from server terminal 140 at any time after 1:52 PM.
In the case of a geographic location such as Vail, Colo. which is designated with a next-day feed type transmission from playlist provider 150, while similar playlist databases 800, 900 shown in FIGS. 8 and 9 are maintained in next day database 152 of playlist provider 150 for each registered radio station in Vail, Colo., playlist provider 150 is configured to transmit playlist of broadcast music clips to server terminal 140 only at a predetermined time unlike the case where the bookmarked broadcast music clips originated from an area designated as a 10-minute feed type transmission.
In one embodiment, for music broadcasts which began before 10 PM, playlist provider 150 may be configured to transmit the corresponding playlists for each registered radio station broadcasts by 5 AM of the following day to server terminal. On the other hand, as discussed above, for bookmarked music broadcasts in Vail, Colo. after 10 PM, playlist provider 150 may be configured to transmit information corresponding to the broadcast music clips to server terminal 140 after 5 AM or within a predetermined time frame from the actual broadcast, for example, within 24 hours from the actual broadcast, or within a predetermined lapsed time from a given set of broadcast times.
For example, for bookmarked music broadcasts between 10 PM and 2 AM, playlist provider 150 may be configured to transmit data corresponding to the bookmarked broadcast music clips to server terminal 140 by 12 PM (or within ten hours from the cutoff broadcast time of 2 AM), and for bookmarked music broadcasts between 2 AM and 5 AM, playlist provider 150 may be configured to transmit data corresponding to the broadcast music clips to server terminal 140 by 5 PM (or within 12 hours from the cutoff broadcast time of 5 AM).
FIG. 10 is a flowchart for illustrating one embodiment of the server terminal procedure for electronic music marker device user playlist notification. Referring to the Figure, at step 1010, gateway terminal 130 connection to server terminal 140 is detected by controller 145 of server terminal 140, and at step 1020 bookmarks from music marker device 110 is received via gateway device 130 I/O interface unit 134 by I/O interface unit 141 of server terminal 140. Then at step 1030, controller 145 queries storage unit 144 to determine whether playlists corresponding to the received bookmarks are available. If it is determined at step 1030 that the playlists corresponding to the received bookmarks are available, then at step 104, the playlists are retrieved from storage unit 144, and at step 1050, server terminal 140 is configured to transmit the retrieved playlists to the user's e-marker.com account accessed from gateway terminal 130. In one embodiment, this is the case for bookmarks generated and received in a geographic location designated for the 10-minute feed type transmission.
On the other hand, if at step 1030 it is determined that the playlists corresponding to the received bookmarks is not available, then at step 1060, server terminal 140 transmits a notification message to the user's e-marker.com account accessed from gateway terminal 130 indicating that the requested information corresponding to the bookmarked music clips are unavailable at the moment, and that the user will be notified when the corresponding playlists become available. The user may at this point optionally log out of the user's e-marker.com account.
At step 1070, controller 145 of server terminal 140 continues to periodically query storage unit 144 to determine whether the playlists for the bookmarked music clips are available, and when controller 145 determines that the corresponding playlists for the user's bookmarked music clips are available, controller 145 in one embodiment is configured to retrieve the user's email address stored in user account database 600 in storage unit 144 and to generate an email notification to the user with a message indicating that the requested information corresponding to the bookmarked music clips is available. Controller 145 in one embodiment may also generate a hypertext link to the user's e-marker.com account and attach the generated link to the email notification to the user.
Referring back to FIG. 10, at step 1080, server terminal 140 is configured to transmit the generated email notification optionally with the hypertext link to the user's email account. Thereafter, when the user retrieves the email notification (for example, from gateway terminal 130) and clicks on the attached hypertext link, user's browser (or any other program or device which allows the user to communicate with server terminal 140 via gateway terminal 130) is configured to be automatically redirected to the user's e-marker.com account. In one aspect, user's account information may be stored as a cookie file in storage unit 137 of gateway terminal 130. Accordingly, user browser redirect automatically logs the user onto the user's e-marker.com account and the information corresponding to the user's bookmarked music clips are displayed one display unit 132 of gateway terminal 130.
Alternatively, in the case where the user has disabled the use of cookie files in gateway terminal 130, when the user points the browser to the hypertext link received in the email notification, the user may be required to input, via input unit 131 for example, the necessary information to log into the user's e-marker.com account, and upon logging on, the user may view the information corresponding to the bookmarked music clips such as the name oft the music clip, the artist and album for the bookmarked music clip, and optionally, album purchase information such as hypertext links to online vendor web sites and the corresponding listed sale prices.
In the manner described above, depending upon geographic location of bookmarked broadcast music clips, users of music marker devices may access information corresponding to the bookmarked music clips near contemporaneously to the bookmarked music clip broadcasts, or alternatively, within a predetermined time frame from the bookmarked music clip broadcasts. While playlist provider 150 is described with a 10-minute feed database 151 and a next-day feed database 152, within the scope of the present invention, other predetermined feed schedule databases may be used.
