Title: Mobile device control of mobile television broadcast signals to alternate destinations

Description:
BACKGROUND OF THE INVENTION  
      The present invention relates to portable mobile communications devices and systems, and more particularly to a portable mobile communications device, system and method that can control the distribution of live television broadcast signals from the mobile device.  
      Portable mobile communications devices such as mobile phones are becoming more sophisticated and include many new features and capabilities. One such feature is the capability to receive mobile broadcast television signals or mobile television or the like, such as digital video broadcast-handheld (DVB-H), digital media broadcast (DMB), integrated services digital broadcast-terrestrial (ISDB-T), mobile broadcast multi-cast service (MBMS), or similar technologies. When integrated into a mobile phone, all of the aforementioned technologies utilize a separate mobile television tuner except for MBMS which can be received using the portable mobile communications device existing mobile radio receiver and transmitter.  
      The convenience factor for receiving such broadcasting is high for mobile users. Unfortunately, the mobile user&#39;s viewing experience is constrained by the mobile equipment itself, particularly the screen size and resolution of the mobile device as well as the bandwidth provided for sending and receiving the mobile broadcast television signals.  
      Currently, there are no provisions addressing the user&#39;s dilemma described above. What is needed is a mechanism that allows the user to direct a mobile video broadcast from the source to an alternate device at higher definitions such as a home media server for later consumption.  
     BRIEF SUMMARY OF THE INVENTION  
      In accordance with an embodiment of the present invention, there is described a portable mobile communications device for altering the destination of mobile television programs broadcast by a mobile television service provider. The portable mobile communications device includes a mobile television device, a processor running a mobile television redirect application communicable with the mobile television service provider, and a user interface for controlling the mobile television redirect application such that mobile television programs (signals) can be redirected to an alternate device and in a higher definition format in response to input received by the user interface and sent to the mobile television service provider. The alternate device can include a home media server, a computer, or other video playback device coupled to and communicable with the mobile television service provider via the Internet.  
      In accordance with another embodiment of the present invention, there is described a method of altering the destination of mobile television programs broadcast by a mobile television service provider to the portable mobile communications device. The method comprises receiving input from a user interface on the portable mobile communications device, the input for selecting a broadcast program from a programming channel guide to be broadcast. A prompt, via a display on the portable mobile communications device, is displayed for one or more destinations for the selected broadcast program and whether to send a higher definition format of the selected program. Input is then received from a user interface on the portable mobile communications device identifying an alternate destination and desired definition (higher or lower) for the selected broadcast program. The portable mobile communications device causes the redirection of the selected broadcast program from the mobile television service provider to the selected alternate destination in the selected lower or higher definition format. This is achieved by wirelessly sending a control signal to the mobile television service provider with instructions to redirect the selected broadcast program from the mobile television service provider to the alternate destination such as a home media server, computer, or other playback device coupled with the mobile television service provider via the Internet.

      The portable mobile communications device  110  may also include a mobile television device  250 . The mobile television device  250  may be a DVB-H type device or the like. The mobile television device  250  may be integrally formed as part of the portable mobile communications device  110  or may be a separate unit that may be connected and operate in association with the portable mobile communications device  110 . The mobile television device  250  may include an antenna assembly  252  for receiving broadcast signals of programming from a mobile television broadcast network, broadcast radio access network (B-RAN)  130  or the like. A receiver  254  may be coupled to the antenna assembly  252  to receive the broadcast signals. A signal processor  256  may receive the broadcast signals from the receiver  254  and convert the signals to a format for presentation on the display  212  of the portable mobile communications device  110 . Or, a signal processor  256  may receive the broadcast signals from the receiver  230  and convert the signals to a format for presentation on the display  212  of the portable mobile communications device  110 .  
      The B-RAN  130  may originate the mobile television or DVB-H broadcast signals for broadcasting to communications devices or mobile television devices, such as portable mobile communications device  110  and mobile television device  250 . The B-RAN  130  may include a transmitter to transmit the broadcast signals.  
      The B-RAN  130  may be connected to a mobile television service provider  132 . The mobile television service provider  132  may originate programming for broadcasting to communications devices  110  or mobile television devices  250  via the B-RAN  130 . The mobile television service provider  132  may include a broadcast application server  134 . The broadcast application server  134  may include an application  136  for redirecting broadcast signals.  
      The B-RAN  130  may be connected to the Internet  140  or other private network that may utilize Internet protocol (IP) or the like. The B-RAN  130  and the mobile television service provider  132  may receive and transmit signals or messages to control the redirecting of broadcast signals via the Internet  140 . Messages and signals to control the playback of recorded programming may also be transmitted and received via the Internet  140 .  
      In another embodiment of the present invention, as discussed with respect to method  300  of  FIG. 3 , a third party recorder such as a notebook computer  150  or a third party record playback application server such as a home media server  160 , or other playback device  180  may be options to receive the redirected broadcast signals and to record the programming carried by the redirected broadcast signals. The third party devices  150 ,  160 ,  180  may be connected to the Internet  140  to receive the redirected broadcasted program. Then, at a later date, the user can access the third party devices  150 ,  160 ,  180  and play back the recorded programming. In the case of a notebook computer  150  (or other like device) the user can access the redirected broadcast directly via the computer and a suitable application hosted thereon. In the case of a home media server  160  (or other like device) the user can access the redirected broadcast via a television  170  (or television monitor) that is connected to the home media server  160 . The combination of the home media server  160  and television  170  would include a suitable application for retrieving, manipulating, and viewing the redirected broadcasted program.  
      One of the added benefits of redirecting the mobile television broadcast signals over the Internet  140  to an alternate destination  150 ,  160  is that the mobile television broadcast signals can be transmitted over a higher bandwidth transmission system for display on a higher resolution display system. Thus, certain alternate destinations can support signals characterized as high definition.  
      Use of a third party device  150 ,  160  as a destination for redirected programming would typically be accomplished via an Internet  140  connection, preferably a broadband connection, between the mobile television service provider  132  and the selected third party device(s)  150 ,  160 . The broadband connection likely affords a higher bandwidth than the wireless mobile television broadcast. The user can control the destination of programming from his portable mobile communications device  110  using its ability to wirelessly communicate with mobile television service provider  132  through M-RAN  120 . The redirect application running on the portable mobile communications device  110  can send control signals to mobile television service provider  132  indicating the destination preference(s) of selected programming. If one or more of the selected preferences is a third party device  150 ,  160  then the mobile television service provider  132  will, via its own redirect application  136 , simultaneously direct a stream of video via the Internet  140  to the desired alternate destination.  
       FIG. 3  is a flow chart of a method for altering the destination and definition of broadcast mobile television signals in accordance with an embodiment of the present invention. In block  310 , the user invokes the television viewing application resident within or attached to the mobile television portable mobile communications device  110 . In block  320 , the user can then access and view a programming guide channel that illustrates the current and future programming available on the channels receivable by the portable mobile communications device  110 . The receivable channels are likely the result of a subscription agreement between the user of the portable mobile communications device  110  and the mobile television service provider  132 . In block  330 , the user will navigate the programming channel guide using the keypad, function buttons, and/or joystick  214  of the portable mobile communications device  110  until he finds and selects a program of interest. In decision block  340 , the redirect application  222  prompts the user via the portable mobile communications device display  212  for a destination for the selected program. The user/viewer then selects one of the destination options. If the user selects the mobile destination then, by default, the program will be sent or broadcast to the portable mobile communications device  110  in the lower (typical) definition format  360 . If a destination other than the default portable mobile communications device  110  or in addition to the default mobile device is selected, the user is also prompted  350  whether the alternate destination should receive a higher definition format of the selected program. The user could be charged a premium for selecting higher definition redirecting as opposed to standard definition or basic (same as mobile) definition television signals. The extra fees can offset the additional bandwidth and coding necessary to ‘push’ the selected program to the desired destination.  
      In block  370 , the redirect application  222  will process the user&#39;s selection and direct the broadcasted program to the desired destination in the selected lower or higher definition format. This is accomplished by wirelessly sending a control signal to the mobile television service provider with instructions to simultaneously redirect the selected broadcast program from the mobile television service provider to the selected destinations.  
      Any prompts associated with the invention may be presented and responded to via an interactive voice feature, a graphical user interface (GUI) presented on the display of the portable mobile communications device or the like.
