Title: Systems and methods for managing content distribution to an in-transit media system

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of U.S. patent application Ser. No. 15/209,415 filed Jul. 13, 2016, which claims the benefit of U.S. Provisional Application No. 62/288,600, filed Jan. 29, 2016, which is incorporated by reference in its entirety. 
    
    
     BACKGROUND 
     The present application relates generally to distribution of media content items to in-transit media systems. More specifically, the present application is directed to managing content distribution to media clients on transport crafts in compliance with media content distribution rights. 
     Transport crafts, such as commercial aircrafts, trains, boats, etc., may have storage-based media systems that store media content items on a server located on the craft in order to provide in-transit media to local media clients. More recently, transport crafts have included systems that provide for network connectivity while in transit, thereby providing local media clients with additional access to streaming media content from sources remote from the craft. For example, such systems may provide streaming media from a remote content server to a local media client via a wireless communication system on the craft. 
     SUMMARY 
     Embodiments of a method for managing media content distribution rights to a media client may include: receiving a request for a media content item from the media client; retrieving a media content distribution region definition for the media content item, wherein the media content distribution region definition indicates one or more media content distribution regions for the media content item; sending the media content distribution region definition for the media content item to a rights location manager; receiving, from the rights location manager, data indicating a current region of the media client, wherein the data is based on a comparison of the media content distribution region definition to a current location of the media client; determining, based on the received data indicating the current region of the media client, whether distribution of the media content item to the media client is authorized within the current region of the media client; initiating a streaming media session for the media content item with the media client when the distribution of the media content item to the media client is authorized within the current region; and providing, via the streaming media session, at least one portion of the media content item to the media client. 
     Some embodiments of the method may further include denying initiation of the streaming media session for the media content item with the media client when the distribution of the media content item to the media client is not authorized within the current region. 
     Some embodiments of the method may further include: receiving, from the rights location manager, data indicating an updated region of the media client after providing the at least one portion of the media content item to the media client; determining, based on the received data indicating an updated region of the media client, whether distribution of the media content item to the media client is authorized within the updated region; providing, via the streaming media session, at least one additional portion of the media content item to the media client when distribution of the media content item to the media client is authorized within the updated region; and terminating the streaming media session with the media client when distribution of the media content item to the media client is not authorized within the updated region. 
     In some embodiments of the method, terminating the streaming media session is due to movement of the media client from an authorized media content distribution region to an unauthorized media content distribution region. 
     Some embodiments of the method may further include sending, to the rights location manager, a request for the updated region of the media client, and wherein the providing, via the streaming media session, the at least one additional portion of the media content item to the media client, is in response to the request for the updated region of the media client. 
     In some embodiments of the method, the request for the updated region of the media client is sent periodically. 
     In some embodiments of the method, the data indicating the updated region of the media client is received in response to movement of the media client. 
     In some embodiments of the method, the retrieving of the media content distribution region definition for the media content item is based on user information associated with the request. 
     In some embodiments, the media client is on a transport craft. 
     In some embodiments, the media client is associated with a fixed terminal. 
     Embodiments of a system for managing media content distribution rights to a media client may include: a memory comprising computer-executable code; at least one processor in data communication with the memory, and configured to execute the computer-executable code and cause the system to: receive a request for a media content item from the media client; retrieve a media content distribution region definition for the media content item, wherein the media content distribution region definition indicates one or more media content distribution regions for the media content item; send the media content distribution region definition for the media content item to a rights location manager; receive, from the rights location manager, data indicating a current region of the media client, wherein the data is based on a comparison of the media content distribution region definition to a current location of the media client; determine, based on the received data indicating the current region of the media client, if distribution of the media content item to the media client is authorized within the current region of the media client; initiate a streaming media session for the media content item with the media client if the distribution of the media content item to the media client is authorized within the current region; and provide, via the streaming media session, at least one portion of the media content item to the media client. 
     In some embodiments of the system, the processor is further configured to cause the system to: deny initiation of the streaming media session for the media content item with the media client if the distribution of the media content item to the media client is not authorized within the current region. 
     In some embodiments of the system, the processor is further configured to cause the system to: receive, from the rights location manager, data indicating an updated region of the media client after providing the at least one portion of the media content item to the media client; determine, based on the received data indicating an updated region of the media client, whether distribution of the media content item to the media client is authorized within the updated region; provide, via the streaming media session, at least one additional portion of the media content item to the media client when the distribution of the media content item to the media client is authorized within the updated region; and terminate the streaming media session with the media client when the distribution of the media content item to the media client is not authorized within the updated region. 
     In some embodiments of the system, the termination of the streaming media session is due to movement of the media client from an authorized media content distribution region to an unauthorized media content distribution region. 
     In some embodiments of the system, the processor is further configured to cause the system to: send, to the rights location manager, a request for the updated region of the media client, and wherein the provision, via the streaming media session, of the at least one additional portion of the media content item to the media client is in response to the request for the updated region of the media client. 
     In some embodiments of the system, the processor is further configured to cause the system to: request the updated region of the media client periodically. 
     In some embodiments of the system, the receipt of the data indicating the updated region of the media client is in response to movement of the media client. 
     In some embodiments of the system, the retrieval of the media content distribution region definition for the media content item is based on user information associated with the request. 
     In some embodiments of the method and system, the movement of the media client is from within the current region to outside the current region.

     DETAILED DESCRIPTION 
     Systems and methods are described herein for distributing media content items to in-transit media systems in compliance with media content distribution rights. 
     Media content items such as television shows and movies are often subject to licenses that restrict the distribution of the media content items. One type of restriction limits the geographical locations where the media content items may be distributed. In the past, when media content items were primarily distributed physically, content distribution rights may have been easily enforced by managing the use of the physical media (e.g., a DVD). As an example, administrators of in-flight entertainment systems that store content locally on airplanes could choose to physically remove or disable playback of media from the entertainment system when the transport craft was in a location not authorized for the media. However, with the availability of data connectivity on transport crafts to sources accessible via remote networks such as the Internet, passengers may have access to media content from providers that are independent of and unaffiliated with the transport craft operator. As such, the methods of restricting distribution of media content items previously used with in-flight entertainment systems may no longer be effective or easily implemented. 
     The advent of continuous network connectivity, which may enable access to remote media content items at all times during transit, requires a carrier to consider whether distribution rights associated with any particular media content item allow for distribution of that media content item at all times during transit. For example, a commercial carrier may only have the right to distribute a particular media content item within a specific geographical region, such as the United States, while the commercial carrier may have the right to distribute another media content item throughout both the United States and Europe. Consequently, as a particular transport craft travels between different regions, the media content items available to local media clients may change. Accordingly, systems and methods are needed to manage the distribution of media content items in compliance with their associated media content distribution rights. 
     An in-transit media system in a transport craft may establish a communication link via a data carrier (e.g., satellite beams, towers, cells, etc.), in order to provide a media content item (e.g., streaming media content) from a content server to media clients associated with or otherwise in data communication with the in-transit media system. As the transport craft moves from location to location, it may exit a region for which the content server is authorized to distribute a particular media content item to the in-transit media system on the transport craft and enter a different region in which the content server is not authorized to distribute the media content item to the in-transit media system on the transport craft. The media content distribution rights associated with a media content item may define where the media content item can be distributed, e.g., a region in which distribution is authorized. Thus, the in-transit media system may work with the content server to stay in compliance with the content distribution rights related to media content items provided to the in-transit media system. 
     The content server may need to verify that the current location of a transport craft is within a region for which the content server is authorized to distribute the media content item. However, the current location data of a transport craft may be purposefully or otherwise unavailable to the content server for security reasons (e.g., to protect the exact location of the transport craft), privacy reasons, or other reasons. For example, a content provider operating the content server may be different than the operator of the transport craft and/or the operator of the communication system over which the content item will be communicated to the transport craft. Thus, providing the current location data of the transport craft to the content server may not always be possible. 
     To solve this problem, embodiments described herein may include a rights location manager that may be able to access the current location of the transport craft. In some embodiments, the rights location manager may provide the content server with the current region of the transport craft, rather than the current location of the transport craft, based on the regional definitions provided by the content server. In other embodiments, the rights location manager may simply provide a binary result (e.g., yes or no) indicating whether or not the current location of the transport craft is within a region defined by the region definitions. By providing only the current region or an indication of being in a region to the content server, the rights location manager enables the content server to distribute media content items to the transport craft in compliance with media content distribution rights, but without knowing the precise current location of the transport craft. 
       FIG. 1  depicts a simplified diagram of an example satellite communication system  100 . Many other configurations having more or fewer components than the satellite communication system  100  of  FIG. 1  are possible. Satellite communication system  100  includes transport craft  110  in data communication with content server  140  via communication link  154 , satellite  105 , communication link  152 , ground terminal  150 , rights location manager  180 , and network  160 . Communication links  152  and  154  may enable a communication link between transport craft  110  and the content server  140 . As depicted in  FIG. 1 , media content items can be obtained from content server  140  via network  160  and ground terminal  150  (and/or other terrestrial stations, gateways, or other network nodes). 
     While a single transport craft  110  (in this example, an airplane) is shown in communication via a single satellite  105  in  FIG. 1 , the techniques described herein can be applied in many other communication environments without departing from the scope of the inventions. For example, transport crafts capable of participating in the communication system shown in  FIG. 1  may include: aircraft (e.g., airplanes, helicopters, blimps, balloons, etc.), trains, automobiles (e.g., cars, trucks, busses, etc.), watercraft (e.g., private boats, commercial shipping vessels, cruise ships, etc.) and others as are known to those of skill in the art. Any or all such transport crafts may communicate via any one or more suitable communication system(s), including any suitable communication links, such as: a satellite communication system, an air-to-ground communication system, a hybrid satellite and air-to-ground communication system, a cellular communication systems, and others as are known by those of skill in the art. Because of the mobile nature of transport craft  110 , the communication system will likely involve at least one wireless communication link, such as the aforementioned examples. 
     Ground terminal  150  may enable bidirectional communication with satellite  105 . In some embodiments, ground terminal  150  may be known as a terrestrial station or a gateway. Ground terminal  150  may also be in data communication with network  160  and thereby to content server  140 . Ground terminal  150  may also be in data communications with rights location manager  180 . 
     Transport craft  110  may include two-way communication system  112  to facilitate bidirectional communication with satellite  105 . In the example depicted in in  FIG. 1 , two-way communication system  112  includes antenna system  170 , transceiver  172 , modem  174 , network access unit  176 , wireless access point (WAP)  178 . Two-way communication system  112  may receive a forward downlink signal from satellite  105  and transmit a return uplink signal to the satellite  105  via communication link  154 . 
     Media clients  120  may include, for example, mobile devices such as personal electronic devices (e.g., smartphones, laptops, tablets, netbooks, and the like) brought onto craft  110  by passengers. As further examples, media clients  125  can also include fixed or on-craft devices, such as passenger seat-back systems or other devices on the transport craft  110 . Media clients  120  and  125  may communicate with the network access unit  176  via a communication link that can be wired and/or wireless (e.g., via wireless access point  178 ). The communication link can be, for example, part of a local area network such as a wireless local area network (WLAN) supported by wireless access point  178 . One or more wireless access points  178  may be distributed about the craft  110  and may, in conjunction with network access unit  176 , provide traffic switching and routing functionality. 
     The media clients  120  and  125  may execute one or more applications that allow users on the transport craft  110  an interface for communicating with the content server  140  to obtain and consume media content items in a streaming (or progressively downloaded manner) via the satellite  105 , ground terminal  150 , satellite  105 , and two-way communication system  112 . The user may have the option to select a media content item from the interface. When a user selects a particular media content item for access, the media clients  120  and  125  may transmit that request to access the media content item to the content server  140  through the satellite communication system  100 . The content server  140 , upon receiving the request, may then determine whether it has authorization to distribute the media content item to the media clients  120  and  125  using the techniques described herein. The users of the media clients  120  and  125  may for example be subscribers of a streaming media service provided by the content server  140 . As another example, the content server  140  may not require a subscription to access the media content items. As yet another example, the subscription to the media content items may be associated with the operator of the craft  110  and/or the operator of the communication system  100 . 
     In other embodiments, media clients may be associated with fixed or nomadic terminals, such as buildings or other structures. In such alternate embodiments, the fixed or nomadic terminal may still be within media content distribution regions, but is not regularly mobile. 
     Network  160  can be any type of network and can include for example, the Internet, an IP network, an intranet, a wide area network (WAN), local area network (LAN), a virtual private network (VPN), a virtual LAN (VLAN), a fiber optic network, a cable network, a public switched telephone network (PSTN), a public switched data network (PSDN), a public land mobile network, a cellular network, and/or any other type of network supporting communication as described herein. Further, network  160  can include both wired (e.g., copper and optical) and wireless (e.g., radio and microwave) connections. 
     Content server  140  may provide various types of media content items, such as linear media content items (e.g., linear audio and/or video media). Linear media content items generally refers to any stream of content that is scheduled for delivery at a certain time (e.g., a television show run at a set time, a live event, a televised sporting event, etc.). For example, various broadcast television channel offerings may be available from the content server  140 . 
     Content server  140  may also provide non-linear programming (e.g., video on demand), which may be available on-demand to media clients  120  and  125  via the satellite communication system  100 . Both linear and non-linear media content items can be communicated from content server  140  to media clients  120  and  125  (e.g., in response to requests for such media from the media clients  120 ), while in flight, via satellite  105 . Although only one content server  140  is depicted in  FIG. 1  for simplicity, media clients  120  and  125  may receive content from one or more other content servers. Each content server  140  may for example be associated with different streaming media content providers. 
     Content server  140  may include one or more media servers, media storage devices, etc., as well as other data stores. 
     As discussed above, content server  140  may receive a request for a media content item from media clients  120  and  125  through the satellite communication system  100 . In some embodiments, the content server  140  may not have access to the current location of the transport craft  110  from which media clients  120  and  125  have requested the media content item. In such embodiments, the content server  140  may retrieve media content distribution rights for the requested media content item, which may, for example, define media content distribution regions within which the media content item may or may not be distributed. The media content distribution rights data (including any associated media content distribution region definitions) may be stored on the content server  140  or on a separate device in data communication with the content server  140 . The media content distribution rights data may be stored in a table or any other type of data structure. 
     Media content distribution rights may be defined in many ways. For example, a media content distribution right may include a media content distribution region defined by geographical features, such as the continent of North America, wherein all locations within the continent of North America are authorized for distribution of a media content item. As another example, a media content distribution right may include a media content distribution region defined by an area within a continent, such as Central Asia, or a nation-state, such as Mexico or Canada, or a time-based region, such as all locations found in Eastern Standard Time. As yet another example, a media content distribution right may include a media content distribution region defined by arbitrary shapes (e.g., defined by sets of coordinates) or with reference to longitude and latitude (e.g., as all locations below a certain meridian, or all locations south of the Equator). Media content distribution rights may also be defined by one or more locations, regions, etc. associated with a convention or treaty, such as the TRIPs Agreement. In some embodiments, media content distribution rights may also include combinations of the factors mentioned above. 
     In some embodiments, a media content distribution right may include a plurality of media content distribution regions, such as a first media content distribution region including locations within the United States (a nation-state) and a second media content distribution region including locations within South America (a continent). 
     In some embodiments, a media content distribution right may include media content distribution regions for which distribution is authorized or media content distribution regions for which distribution is not authorized. For example, a media content distribution right may prohibit distribution within the United States. 
     Media content distribution rights may also be based on user information associated with the user requesting a media content item through the media client. For example, a content server may be authorized to distribute a media content item to a particular user in all media content distribution regions while the content server may only be authorized to distribute the media content item to another user in certain media content distribution regions. As another example, the user information may be related to the carrier (e.g., airline) or provider of the media client. As yet another example, the user information may associated with a particular craft (e.g., a particular airplane) containing the media client and/or the source and/or destination of the craft. As yet another example, the user information may be associated with the headquarters of the carrier. 
     User information may be transmitted with the request for the media content item, and may include any sort of aspect associated with the user. 
     Media content distribution rights may also be based on additional information, for example, the owner of the transport craft containing the media client, the technology supporting the media client, the technology in the transport craft, or the source and/or the destination of the craft. Other types of information are possible as would be appreciated by one of skill in the art. 
     Upon determining the media content distribution right (including any associated media content distribution region definitions) for a requested media content item, the content server  140  may send, for example, the media content distribution region definition(s) to the rights location manager  180 . The content server  140  may also send information (e.g., the source IP address within the request for media content item) that can be used by the rights location manager  180  to identify the particular transport craft  110  from which the request originated. In embodiments in which the content server  140  provides media streaming service to other media clients that may not be located on a transport craft, the content server  140  may analyze the request to determine whether or not the request originated from a media client on a transport craft. If the content server  140  determines that the request was from a media client on a transport craft, the content server  140  may then send the media content distribution region definition(s) to the rights location manager  180 . A variety of techniques may be used to determine whether the request originated from a transport craft. For example, in some embodiments the content server  140  stores a list of IP addresses of the various two-way communication systems  112  on the various transport craft  110 , and looks up the source IP address within the request in the list to determine whether or not the request originated from a media client on a transport craft. 
     Rights location manager  180  may include a data store or server. The functions of the rights location manager  180  can be implemented in hardware, instructions embodied in memory and formatted to be executed by one or more general or application-specific processors, firmware, or any combination thereof. In the example depicted in  FIG. 1 , rights location manager  180  is shown as a separate device that is earth-bound. In other embodiments, some or all of the functionality of the rights location manager  180  may be placed within the transport craft  110 . 
     The rights location manager  180  may have access to the current location of the transport craft  110 . In some embodiments, the rights location manager  180  receives the current location of the transport craft  110  from the transport craft  110  itself through the satellite communication system  100 . For example, the current location of the transport craft  110  may be provided via a global positioning system (GPS) or other equipment on the transport craft  110 . In other embodiments, the rights location manager  180  may determine the current location based on, for example, current speed and expected travel route or heading of the transport craft  110 . In yet other embodiments, the rights location manager  180  may receive the current location of the aircraft from other sources, such as flight tracking radar services and the like. In yet other embodiments, the rights location manager  180  may determine the current location based on the manner in which the transport craft  110  communicates with the satellite communication system  100 . For example, in embodiments in which the satellite  105  is a satellite having a coverage area only over the continental United States, the current location may be determined based on whether or not the transport craft  110  is communicating with the satellite  105 . As another example, in embodiments in which the satellite  105  is a multi-beam satellite with spot beams having different coverage areas, the current location may be the coverage area of the spot beam with which the transport craft  110  is communicating with the satellite  105 . Thus, it will be understood that the current location of the transport craft  110  obtained by the rights location manager  180  may not necessarily be its precise location. Rather, the current location may be a geographic area with boundaries sufficient that the techniques described herein can be used. 
     Upon receiving the media content distribution region definition(s) for a requested media content item, the rights location manager  180  may identify the particular transport craft  110  from which the request originated. For example, in embodiments in which the rights location manager  180  sends the source IP address within the request for media content item, the rights location manager  180  may check the source IP address against a list of IP addresses associated with the various transport crafts  110 . The rights location manager  180  may then compare the current location of the transport craft  110  to the media content distribution regions and determine which of the media content distribution regions the transport craft  110  is currently in. For example, the rights location manager  180  may have received a media content distribution region definition from the content server  140  defining a first media content distribution region including locations within the United States and a second media content distribution region including locations within Europe. The rights location manager  180  may compare the current location of the transport craft  110  to the first and second media content distribution regions and determine that the current region of the transport craft  110  is the first media content distribution region, i.e., the United States. The rights location manager  180  may then communicate to the content server  140  that the transport craft  110  is in the first media content distribution region. 
     In some embodiments, the rights location manager  180  may determine that the transport craft is not within any of the defined media content distribution regions. The rights location manager  180  may then communicate to the content server  140  data indicating only that no match was made, rather than any current region of the transport craft. 
       FIG. 2  provides an example of how a transport craft  110  may travel through several media content distributions regions, such as  220   a - e , while in transit along a path  210  or a path  212 . For example, path  210  takes transport craft  110  from a media content distribution region  220   a , which includes the United States, to another media content distribution region  220   d , which includes Japan, while also traversing media content distribution regions including the United Kingdom and China ( 220   b  and  220   c , respectively). Path  212  takes transport craft  110  from media content distribution region  220   a , which includes the United States, to media content distribution region  220   e , without passing through any other media content distribution regions. In embodiments, a particular media content item may only be authorized for distribution in media content distribution region  220   b , which means that flights along path  212  would never have access to that particular media content item. 
       FIGS. 3A and 3B  provide examples of media content distribution rights data (including any associated media content distribution region definitions), including media content distribution regions, which may be used by the content server and the rights location manager in order to determine whether a media content item may be distributed to a media client. For example, as shown in  FIG. 3A , the content server may distribute the media content item “Sports Event Live Broadcast” to the continental United States whereas the content server may distribute the media content item “Cricket Match” to the United Kingdom. 
       FIG. 3B , provides another example of media content distribution rights data (including any associated media content distribution region definitions), including media content distribution regions. In  FIG. 3B , each media content item may have multiple media content distribution regions along with authorization settings for each media content distribution region. For example, the media content item “Sports Event Live Broadcast” is associated with three media content distribution regions, and each media content distribution regions includes an authorization setting. Thus, in the example depicted in  FIG. 3B , “Sports Event Live Broadcast” may be distributed to the Continental U.S. and to the United Kingdom, but not to North Korea. 
       FIG. 4  shows an embodiment of a method for managing distribution of media content items to in-transit media systems in compliance with media content distribution rights. 
     In step  402 , a content server receives a request for a media content item. The request may have originated from a media client such as  120  or  125  on a transport craft, such as craft  110 . For example, the requested media content item could be on-demand content, such as a movie, a song, or a television show, or the media content item may alternatively be linear media data, such as a live television program. 
     In step  404 , the content server retrieves media content distribution rights data including one or more media content distribution region definition(s) for the requested media content item. As discussed in relation to  FIG. 3A , the media content distribution region definition(s) for a requested media content item may define one or more media content distribution regions in which the content server may or may not have authorization to distribute the media content item. 
     In step  406 , the content server sends the retrieved media content distribution region definition(s) for the requested media content item to a rights location manager. 
     Upon receiving the media content distribution region definition(s), the rights location manager may determine whether the transport craft (and associated media client) is within one of the defined media content distribution regions. 
     At step  408 , the content server receives data indicating whether or not the transport craft is in one of the defined media content distribution regions. 
     In other embodiments, the rights location manager may instead provide a response indicating whether the current region of the transport craft is in one of the authorized regions for distribution of the media content item (e.g., the Boolean response could be ‘true’; otherwise if the current region of the transport craft is in an unauthorized region, the Boolean response would be ‘false’). In such an embodiment, i.e., where the rights location manager indicates that the media client is in an authorized content distribution region, the content server may go directly to step  412  and initiate the streaming of the requested media content item. 
     At step  410 , the content server determines, based on the data indicating the current region of the transport craft and media client, whether distribution of the media content item to the transport craft and media client is authorized. 
     If the data received from the rights location manager, which may be the current region of the media client, indicates that the media client is not within an authorized media content distribution region, then the method returns to step  402  and awaits another request for a media content item. 
     If the data received from the rights location manager indicates that the media client is within an authorized media content distribution region, then at step  412  the content server initiates a streaming media session for the media content item on the media client. The streaming media session can be established between the content server and the media client on the transport craft through a communication system, such as a satellite communication system, an air-to-ground communication system, a cellular communication system, and others as known by those of skill in the art. 
     At step  414  the content server provides at least one portion of the media content item to the media client on the transport craft. 
     Notably, while an initial authorization determination is made in  FIG. 4 , the transport craft may transit out of one region and into another region, which may or may not be authorized for distribution of the requested media content item. As such, the content server and the region location manager may periodically determine whether the transport craft is within an updated media content distribution region and whether or not that updated media content distribution region is an authorized content distribution region. The periodic determination may occur on a regular time interval, an irregular time interval, or be triggered by an event, such as the transport craft passing into a new geographic area (independent of the media content distribution regions defined by the content server). 
       FIG. 5  depicts an embodiment of a method  500  for periodically re-authorizing the distribution of media content items to an in-transit media system. 
     At step  502 , while a streaming media session exists between the content server and the media client on a transport craft, and after at least one portion of a media content item has been received by the media client on the transport craft, the content server may request an update from the rights location manager as to whether the current region of the transport craft has changed. In response, the rights location manager may again compare the media content distribution region definition(s) for the received media content item to an updated location of the transport craft in order to determine the current content distribution region of the transport craft. The result of the comparison may be data indicating an updated region for the media client. 
     At step  504 , the content server receives, from the rights location manager, data indicating an updated region for the transport craft and media client. 
     In some embodiments, when the media content distribution region definition defines only the authorized content distribution regions for the media content item, the data resulting from the comparison of the content distribution regions and the transport craft&#39;s updated location may be limited to only an indication that the media client is within an authorized content distribution region. When the data is only an indication that the media client is still in an authorized content distribution region, the content server may be directed to continue providing portions of the media content item in the streaming media session. 
     At step  506 , the content server determines, based on the data indicating the updated region of the media client, whether distribution of the media content item to the media client is still authorized. 
     If the content server determines that the updated region of the media client is still authorized, then at step  508 , the content server provides at least one additional portion of the media content item via the streaming media session to the media client on the transport craft. 
     If the content server determines that the updated region of the media client is not authorized, then at step  510  the content server terminates the streaming media session. 
     As described above, in some embodiments, the content server may periodically request an updated region of the media client. In other embodiments, instead of waiting for the request for an updated region from the content server, the rights location manager may periodically update the location of the media client and send updated location data to the content server proactively. For example, the rights location manager may, without prompting from the content server, compare the received media content distribution region definition to the current location of the media client. Upon determining that the media client is in a new content distribution region, the rights location manager may send data indicating an updated region of the media client. 
       FIG. 6  shows a flow diagram  600  of aspects of a system for managing media content distribution to an in-transit media system in compliance with media content distribution rights. 
     At step  602  a media client in a transport craft makes a request for a media content item. The media content item may be, for example, a live television show. 
     At step  604 , the content server receives the request for the media content item. 
     At step  606 , the content server retrieves media content distribution rights data including one or more media content distribution region definition(s) for the media content item. As previously discussed, the media content distribution region definition(s) for the media content item may define one or more media content distribution regions within which distribution of the media content item is authorized or unauthorized. 
     At step  608 , the content server sends the retrieved one or more media content distribution region definition(s) to the rights location manager. 
     At step  610 , the rights location manager compares the current location of the transport craft (associated with the media client) with the one or more media content distribution region definition(s) to determine whether the transport craft is within any of the defined media content distribution regions. 
     At step  612 , the rights location manager sends data indicating the current region of the media client to the content server. In other embodiments, the data may indicate only whether the media client and transport craft are within an authorized content distribution region, without identifying which region the media client and transport craft are within. In yet other embodiments, the rights location manager may send data indicating that the transport craft is not within any of the defined media content distribution regions. 
     At step  614 , the content server determines, based on the data indicating a current region of the transport craft (associated with the media client), whether the distribution of the media data content item is authorized within the current region of the media client. 
     If the content server determines that the current region of the transport craft (associated with media client) is not authorized for distribution of the media content item, then at step  616  the content server does not initiate a streaming media session, and the media content item will not be provided to the media client on the transport craft. 
     If the content server determines that the current region of the transport craft (associated with media client) is authorized for distribution of the media content item, then at step  618 , the content server initiates a streaming media session with the media client. 
     At step  620 , the content server sends at least one portion of the media content item to the media client on the transport craft. 
     At step  622 , the media client on the transport craft receives the at least one portion of the media content item sent by the content server. 
     At step  624 , the content server sends a request to the rights location manager to determine whether the transport craft (associated with the media client) is still within an authorized content distribution region. As described above, such a request may occur at regular intervals, irregular intervals, or in response to some event. 
     At step  626 , in response to the content server&#39;s request to provide an updated region of the media client, the rights location manager compares the updated location of the transport craft (associated with the media client) with the media content distribution region definition(s) provided by the content server at step  608  to determine an updated region of the media client. 
     At step  628 , the rights location manager sends data indicating an updated region of the media client. 
     At step  630 , the content server determines, based on the received data, whether the distribution of the media content item is authorized within the updated region of the media client. 
     If the content server determines that the current region of the transport craft (associated with media client) is not authorized for distribution of the media content item, then at step  632 , the content server terminates the streaming media session with the media client. 
     If the content server determines that the current region of the transport craft (associated with media client) is authorized for distribution of the media content item, then the content server returns to step  620  and provides another portion of the media content item requested by the media client.

     In the present disclosure, certain terminology is used in the following ways. The singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to an item includes reference to one or more items. The term “ones” refers to one, two, or more, and generally applies to the selection of some or all of a quantity. The term “plurality” refers to two or more of an item. The term “about” means quantities, dimensions, sizes, formulations, parameters, shapes and other characteristics need not be exact, but can be approximated and/or larger or smaller, as desired, reflecting acceptable tolerances, conversion factors, rounding off, measurement error and the like and other factors known to those of skill in the art. The term “substantially” means that the recited characteristic, parameter, or value need not be achieved exactly, but that deviations or variations including, for example, tolerances, measurement error, measurement accuracy limitations and other factors known to those of skill in the art, can occur in amounts that do not preclude the effect the characteristic was intended to provide. Numerical data can be expressed or presented herein in a range format. It is to be understood that such a range format is used merely for convenience and brevity and thus should be interpreted flexibly to include not only the numerical values explicitly recited as the limits of the range, but also interpreted to include all of the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. As an illustration, a numerical range of “about 1 to 5” should be interpreted to include not only the explicitly recited values of about 1 to about 5, but also include individual values and sub-ranges within the indicated range. Thus, included in this numerical range are individual values such as 2, 3 and 4 and sub-ranges such as 1-3, 2-4 and 3-5, etc. This same principle applies to ranges reciting only one numerical value (e.g., “greater than about 1”) and should apply regardless of the breadth of the range or the characteristics being described. A plurality of items can be presented in a common list for convenience. However, these lists should be construed as though each member of the list is individually identified as a separate and unique member. Thus, no individual member of such list should be construed as a de facto equivalent of any other member of the same list solely based on their presentation in a common group without indications to the contrary. Furthermore, where the terms “and” and “or” are used in conjunction with a list of items, they are to be interpreted broadly, in that any one or more of the listed items can be used alone or in combination with other listed items. The term “alternatively” refers to selection of one of two or more alternatives, and is not intended to limit the selection to only those listed alternatives or to only one of the listed alternatives at a time, unless the context clearly indicates otherwise. The term “coupled” as used herein does not require that the components be directly connected to each other. Instead, the term is intended to also include configurations with indirect connections where one or more other components can be included between coupled components. For example, such other components can include amplifiers, attenuators, isolators, directional couplers, redundancy switches, and the like. Also, as used herein, including in the claims, “or” as used in a list of items prefaced by “at least one of” indicates a disjunctive list such that, for example, a list of “at least one of A, B, or C” means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Further, the term “exemplary” does not mean that the described example is preferred or better than other examples. As used herein, a “set” of elements is intended to mean “one or more” of those elements, except where the set is explicitly required to have more than one or explicitly permitted to be a null set. 
     Various changes, substitutions, and alterations to the techniques described herein can be made without departing from the technology of the teachings as defined by the appended claims. Moreover, the scope of the disclosure and claims is not limited to the particular aspects of the process, machine, manufacture, composition of matter, means, methods, and actions described above. Processes, machines, manufacture, compositions of matter, means, methods, or actions, presently existing or later to be developed, that perform substantially the same function or achieve substantially the same result as the corresponding aspects described herein can be utilized. Accordingly, the appended claims include within their scope such processes, machines, manufacture, compositions of matter, means, methods, or actions.
