Abstract:
Systems and methods for scheduling audio and/or visual content for recording using a mobile station are provided. A mobile station can display a content guide listing audio and/or visual content. When a dispatch button is depressed, a request for recording of the audio and/or visual content which is currently selected is sent to a server. The server forwards the request to a television device, which schedules the recording of the selected audio and/or visual content. Reminder messages regarding upcoming audio and/or visual content can be sent to the mobile station. If a dispatch button of the mobile station is depressed when the reminder message is being displayed, a request to record the audio and/or visual content identified in the reminder message is sent to the television device.

Description:
BACKGROUND OF THE INVENTION  
       [0001]     In order to increase revenues, wireless network operators are offering an increasing variety of services to mobile stations. For example, some wireless network operators offer music and video on demand. However, most services offered by wireless network operators are designed solely for use by mobile stations. One service offered by wireless network operators which interacts with other devices are picture services. Specifically, some wireless network operators allow pictures captured by a mobile station to be e-mailed to any type of e-mail account, e.g., one which can be access by a computer.  
         [0002]     As technology continues to advance, consumers are burdened with a number of technologies which operate independently of each other. For example, although devices for recording audio and/or visual content and computers have coexisted for some time, only recently have consumers been provided with the ability to use computers to remotely schedule the recording of audio and/or visual content. However, in an increasingly mobile society, there will be many times when a consumer is not located near a computer with Internet access, which is required to remotely schedule the recording of audio and/or visual content.  
       SUMMARY OF THE INVENTION  
       [0003]     The present invention provides systems and methods for mobile stations to request that a television device record audio and/or visual content, while providing user-friendly techniques which take advantage of the limited number of buttons on a mobile station. In accordance with the present invention, a dispatch button is used for requesting that audio and/or visual content be scheduled for recording. The mobile station can receive a reminder message that particular audio and/or visual content is upcoming, and depression of the dispatch button while the message is displayed, will send a request that the particular audio and/or visual content be scheduled for recording. Additionally, the mobile station can display a content listing of upcoming audio and/or visual content, and depression of the dispatch button will send a request that selected audio and/or visual content be scheduled for recording. The selected audio and/or visual content can be highlighted content within the content listing or it can be content for which description information is being displayed.  
         [0004]     Use of the dispatch button to request that audio and/or visual content be scheduled for recording takes advantage of the limited number of buttons available on mobile stations. Specifically, unlike television remote control devices, mobile stations will not have a dedicated record button. Accordingly, the alternative to the present invention would require a user to navigate through a number of menu items to select particular audio and/or visual content to be scheduled for recording. Specifically, when a user selects a particular audio and/or visual content, the user would be provided with an additional menu, which may provide the option for scheduling the recording of the particular audio and/or visual content. Accordingly, the present invention increases user satisfaction by reducing the number of buttons required to schedule the recording of particular audio and/or visual content.  
         [0005]     Other objects, advantages and novel features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0012]     Most public wireless communications networks, such as cellular communication networks, typically provide interconnect voice communication services. Interconnect voice communication services are what is typically referred to as circuit-switched communications. Accordingly, wireless network operators provide services based on interconnect voice communication services. However, some networks provide both interconnect and dispatch communication services. One such network is the iDEN network, such as the one owned and operated by Nextel Communications, Inc., of Reston Va. Dispatch communication services are commonly referred to as walkie-talkie communication services because of the half-duplex nature of the communications, i.e., only one party may speak at a time.  
         [0013]      FIG. 1  illustrates an exemplary mobile station capable of performing dispatch communications. A mobile station can be conventional wireless telephones, wireless computers, wireless personal digital assistants (PDAs), and the like. As illustrated in  FIG. 1 , in addition to the display, numbered keypad, send, clear and end keys, dispatch mobile stations include a dispatch button, commonly referred to as a push-to-send or push-to-talk button. In order to speak during a dispatch communication, the dispatch button must be depressed. As will be described in more detail below, the present invention employs the dispatch button for requesting that particular audio and/or visual content be scheduled for recording. As used herein, audio and/or visual content can be television shows, music programming, radio programming, stored audio and/or visual information, and the like.  
         [0014]      FIG. 2  is a block diagram of an exemplary network for allowing a mobile station to request that audio and/or visual content be scheduled for recording in accordance with the present invention. The network includes one or more customer premises  105  coupled to a broadcast video head-end  120 , such as a cable, satellite or over-the-air network head-end. Each customer premises includes a television device  110  coupled to a television  115 . Although the television device  110  is illustrated as being a component external to the television  115 , the television device  110  can be an integral component of the television  115 . The television device  110  includes the capability to record audio and/or visual content. For example, the television device can be a digital video recorder (DVR), video cassette recorder (VCR), or the like. If content from broadcast video head-end  120  is encrypted, the television device  110  can include components for decrypting content, or the television device can receive decrypted content from another device (not illustrated) located on the customer premises  105 , and coupled to the broadcast video head-end  120 .  
         [0015]     The broadcast video head-end  120  is coupled to a content server  130 , television device server  135  and a wireless network  150  via the Internet  125 . Although the content server  130  is illustrated as being coupled to the wireless network  150  via Internet  125 , the content server  130  can be a component of the wireless network  150 . The broadcast video head-end and the television device server  135  are coupled to the wireless network  150  via one or more gateways  155 . The wireless network  150  supports communications for one or more mobile stations  160 . The mobile stations  160  include the ability to perform dispatch communications, and include a dispatch button, such as the one illustrated in  FIG. 1 . The television device server  135  communicates with television device  110 , content server  130 , and wireless device  160  in order to receive requests from mobile station  160  that audio and/or visual content be scheduled for recording, and sends the instructions to television device  110 . The television device server  135  can be a group communication server, such as the one described in U.S. patent application “System and Method for Interactivity Between Mobile Stations and a Television Device” by Tabassi et al., filed on even date herewith. The entire disclosure of the aforementioned patent application is herein expressly incorporated by reference.  
         [0016]     In order to provide services to television device  110 , the television device server  135  includes a user database  140 , which stores information for each subscriber, i.e., each television device  110 , such as the mobile stations associated with television device  110  that can request that audio and/or visual content be scheduled for recording by television device  110 . The content server  130  stores information related to audio and/or visual content provided by broadcast video head-end  120 . This information includes listings of audio and/or visual content and descriptions of the audio and/or visual content. The content server  130  can also store preferences of users of television device  110 . Alternatively, user preferences can be stored in user database  140  or television device  110 .  
         [0017]     The operation system of  FIG. 2  will now be described in connection with  FIGS. 3   a - 3   c  and  4 .  FIG. 3   a  is an exemplary call flow diagram for recording audio and/or visual content using a mobile station in accordance with one embodiment of the present invention. In accordance with exemplary embodiments of the present invention, a user can provide the content server with their content preferences, or the content server can automatically determine the content preferences based on the user&#39;s previous recordings. The content preferences are general user preferences of the type of content preferred by a user, such as reality shows, sports or the like. However, a user can also set reminders for particular content. Additionally, a mobile station which receives a reminder can forward the reminder to another mobile station.  
         [0018]     When content server  130  determines that particular audio and/or visual content matches preferences of a user of television device  110 , a predetermined amount of time prior to the broadcast of the content for specific reminders, or when the forwarded reminder is received by the content server  130 , the content server  130  sends a Record Reminder, including the content information and a content identification, to television device server  135 . The Record Reminder message can be an e-mail with an eXtensible Markup Language (XML) body. The following is an exemplary Record Reminder:  
                                                                                                                         TO:   mobileremote@television_device_server.com       FROM:   mobileremote@content_server.com       SUBJECT:   record reminder            &lt;MobileRemote&gt;                &lt;RecordReminder version=version number&gt;                &lt;RequestID&gt;022105-12:46:02-456799&lt;/RequestID&gt;           &lt;PhoneNumber&gt;3035551001&lt;/PhoneNumber&gt;           &lt;Channel number=“013” name=“Channel Name”&gt;                &lt;Show&gt;                &lt;Name&gt;Show name&lt;/Name&gt;           &lt;Description&gt;Show Description&lt;/Description&gt;           &lt;BeginTime&gt;08:00pm EST&lt;/BeginTime&gt;           &lt;Date&gt;02/25/2005&lt;/Date&gt;           &lt;Duration&gt;60&lt;/Duration&gt;                &lt;/Show&gt;                &lt;/Channel&gt;                &lt;/RecordReminder&gt;            &lt;/MobileRemote&gt;                  
 
         [0019]     Television device server  135  has a pool of unallocated dispatch mobile station identifiers, such as the UFMI identifiers used in iDEN, which can be assigned to particular content. The dispatch mobile station identifiers can be assigned to content on a per content, per content and user, or per session basis. The per content basis assigns a single dispatch mobile station identifier for particular content to every mobile station receiving a reminder for the particular content. The per content and user basis assigns a unique dispatch mobile station for particular content for each mobile station. The per session basis assigns a unique dispatch mobile station identifier for particular content for a predetermined amount of time, the expiration of which allows the identifier to be reused. Using any one of the aforementioned techniques, the television device server  135  assigns a dispatch mobile station identifier to the particular content, and sends a Record Reminder message, including the content information and the assigned dispatch mobile station identifier, to mobile station  160 . The Record Reminder message can be sent as a short message service (SMS) or multimedia messaging service (MMS) message.  
         [0020]     The user of mobile station  160  can review the content information to determine whether the particular content should be scheduled for recording. If the user of mobile station decides that the particular content should be scheduled for recording, the user can actuate the dispatch button, which causes the mobile station  160  to send a Record Request to the television device server  135 . The record request can be sent as a dispatch communication with the calling party identifier being the dispatch mobile station identifier included in the Record Reminder message received from television device server  135 . The wireless network  150  will recognize that the dispatch mobile station identifier is associated with the television device server  135 , and forward the message to the television device server  135 .  
         [0021]     The television device server  135  then sends a Record Request, including the content identification and identifying the particular television device  110  associated with the mobile station  160 , to the content server  130 . The Record Request can be an HTTP POST message, which is formatted as follows:  
                                                                                                                                   &lt;MobileRemote&gt;                &lt;RecordRequest version=version number&gt;                &lt;RequestID&gt;022105-12:46:02-456799&lt;/RequestID&gt;           &lt;PhoneNumber&gt;3035551001&lt;/PhoneNumber&gt;           &lt;Channel number=“013” name=“Channel Name”&gt;                &lt;Show&gt;                &lt;Name&gt;Show name&lt;/Name&gt;           &lt;Description&gt;Show Description&lt;/Description&gt;           &lt;BeginTime&gt;08:00pm EST&lt;/BeginTime&gt;           &lt;Date&gt;02/25/2005&lt;/Date&gt;           &lt;Duration&gt;60&lt;/Duration&gt;                &lt;/Show&gt;                &lt;/Channel&gt;                &lt;/RecordRequest&gt;                &lt;/MobileRemote&gt;                      
 
         [0022]     The content server  130  sends a Record Request, including the content identification, to the television device  110 . When the television device  110  has scheduled the recording of the content, a Record Request Response, including a confirmation that the content has been scheduled for recording, is sent to the content server  130 . The content server  130  then sends a Confirmation message, including the content information and the confirmation to the television device server  135 . The Confirmation message can be an e-mail with an XML body, which is formatted as follows:  
                                                                                                                         TO:   mobileremote@television_device_server.com       FROM:   mobileremote@content_server.com       SUBJECT:   record request response            &lt;MobileRemote&gt;                &lt;RecordConfirm version=version number&gt;                &lt;Result&gt;200&lt;/Result&gt;           &lt;Description&gt;Recording Confirmed&lt;/Description&gt;           &lt;ResponseID&gt;022105-12:46:02-456800&lt;/RequestID&gt;           &lt;PhoneNumber&gt;3035551001&lt;/PhoneNumber&gt;           &lt;Channel number=“013” name=“Channel Name”&gt;                &lt;Show&gt;                &lt;Name&gt;Show name&lt;/Name&gt;           &lt;Description&gt;Show Description&lt;/Description&gt;           &lt;BeginTime&gt;08:00pm EST&lt;/BeginTime&gt;           &lt;Date&gt;02/25/2005&lt;/Date&gt;           &lt;Duration&gt;60&lt;/Duration&gt;                &lt;/Show&gt;                &lt;/Channel&gt;           &lt;Attachment FileName=“show.wav” Description=Description/&gt;                &lt;/RecordConfirm&gt;            &lt;/MobileRemote&gt;                  
 
 MIME attachment containing .wav and/or gif objects 
 
         [0023]     As illustrated in the exemplary message above, the content server  130  can send audio and/or visual attachments to the television device server  135 , for forwarding to the mobile station  160 . Alternatively, or additionally, the attachment can be provided by the television device server  135  or another server (not illustrated) that is dedicated to providing wallpaper and/or audio files (e.g., ring tones). The attachments can include information related to the particular content scheduled for recording, such as an audio file of the theme song, a wallpaper picture related to the content, or a short video clip related to the content (e.g., a trailer).  
         [0024]     The television device server  135  sends a Confirmation message to mobile station  160 . The Confirmation message can be an SMS, or MMS message, and may include the attachments sent from the content server  130 . Alternatively, the Confirmation message can be sent as a dispatch communication message, e.g., a prerecorded voice can say “Your selection has been scheduled for recording.” Additionally, the dispatch communication message can be related to the content scheduled for recording. For example, the dispatch communication message can be a tag line of the content scheduled for recording, such as words or phrases frequently used by characters in the content scheduled for recording. If the dispatch communication message is related to the content scheduled for recording, the message can be based on an audio file provided by the content server  130 . Although not illustrated, if the television device cannot schedule the recording, e.g., due to a time conflict with a previously scheduled recording, the television device  110  will send a confirmation message indicating such, which can be forwarded to the mobile station  160 .  
         [0025]      FIG. 3   b  is an exemplary call flow diagram for recording audio and/or visual content using a mobile station in accordance with another embodiment of the present invention. The call flow diagram of  FIG. 3   b  is similar to that of  FIG. 3   a,  except that the content server is not involved. Specifically, the television device  110  forwards the Record Reminder message to the television device server  135 , receives the Record Request message from the television device server  135 , and sends the Confirmation message to the television device server  135 . If the Confirmation message includes an attachment, the television device server can obtain the information for the attachment either from content server  130  or from a local database (not illustrated).  
         [0026]      FIG. 3   c  is an exemplary call flow diagram for recording audio and/or visual content using a mobile station in accordance with yet another embodiment of the present invention. In accordance with the embodiment illustrated in  FIG. 3   c,  the television device server  135  can store preferences of users of television device  110  in database  140 . Accordingly, the television device server  135  will not receive the first Record Reminder message illustrated in  FIGS. 3   a  and  3   b.  If the Confirmation message includes an attachment, the television device server  135  can obtain the information for the attachment from content server  130 , a local database (not illustrated), the television device  135  itself, or another server (not illustrated) that is dedicated to providing wallpaper and/or audio files (e.g., ring tones).  
         [0027]     Although  FIGS. 3   a - 3   c  have been described as assigning a dispatch mobile station identifier to be included in the Record Reminder, and the mobile station sending the Record Request as a dispatch communication, the present invention can also employ interconnect communications for this purpose. Specifically, an interconnect mobile station identifier (i.e., a conventional telephone number) can be assigned to the audio and/or visual content on any of the basis mentioned above, and the mobile station can send the Record Request to the particular interconnect mobile station identifier. Similarly, electronic mail addresses can be used instead of the dispatch mobile station identifiers.  
         [0028]      FIG. 4  is a flow diagram illustrating an exemplary method for requesting that a particular audio and/or visual content be scheduled for recording. In accordance with the present invention, a mobile station  160  can obtain a content guide from television device server  135 , which obtained the content guide from content server  130 . Accordingly, the mobile station  160  can display the content guide (step  405 ) and wait for a command from the user of the mobile station  160 . When the scroll button is depressed (“Yes” path out of decision step  410 ), the mobile station  160  will scroll the display of the content guide (step  415 ). When the select button is depressed (“Yes” path out of decision step  420 ), then the mobile station will display information for the content which is currently highlighted in the content guide (step  425 ). The information can be a description of the selected content and can be downloaded from television device server  135 . While the content information is being displayed, if the clear button is depressed (“Yes” path out of decision step  430 ), then the content guide is displayed (step  405 ).  
         [0029]     When the dispatch button is depressed (“Yes” path out of decision step  435 ), the mobile station  160  sends a request to record the content that is currently highlighted in the content guide or the content for which the content information is being displayed (step  440 ). The mobile station then receives confirmation from the television device server  135 , that the selected content has been scheduled for recording (step  445 ). The confirmation message can be the same as that described above in connection with  FIGS. 3   a - 3   c,  i.e., it can be an SMS or MMS message with audio and/or visual attachments, or it can be a dispatch communication message with an audio confirmation or tag line associated with the content.  
         [0030]     Although exemplary embodiments have been described as using particular types of messages and message formats, the present invention can employ other types of messages and message formats.  
         [0031]     The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
