The present invention relates to targeted media content delivery, and more specifically, to the synchronization of targeted media content delivery with a radio broadcast signal.
The evolution of the Internet and mobile devices have lead many traditional radio broadcast systems to offer their own mobile device application for online streaming and on-demand services. However, for vehicles, such as automobiles, trains, and buses, the main type of audio and visual output system available is still terrestrial and satellite radio broadcasting systems which transmit media content through unidirectional radio signals.
Unidirectional radio broadcasting will continue to offer a number of important advantages for vehicle audio systems. First, terrestrial and satellite radio broadcasting offer ubiquitous coverage compared to cellular networks which often have patchy coverage in rural areas. Second, unidirectional radio broadcasting does not add to the network capacity concerns about cellular and other wireless networks becoming more congested as multimedia streaming becomes more widely adopted. Third, online streaming over the Internet includes a cost for the end user in terms of traffic data and mobile device power autonomy.
Commercial radio broadcast systems often rely on their ability to deliver media content to listeners to generate income. Many such commercial radio broadcast systems offer specific time slots during their main programming to customers, during which the customer's media content would be delivered to the listeners. When media content is delivered using cellular or other wireless networks, such media content can be targeted to specific listeners or groups or listeners using profile information gathered from the listener mobile devices. However, the unidirectional nature of radio broadcasting lacks the ability to offer a “feedback loop” where profile information can be gathered for use in identifying targeted media content. Further, even if such targeted media content can be provided to listeners through a different channel, the radio broadcast system is not able to synchronize the play of such media content with a specific time slot during their main programming. Thus, the radio broadcasting systems deliver the same media content to all listeners.
Disclosed herein is a method for synchronizing a play of a targeted media content with a time slot in a radio broadcast signal, and a computer program product and system as specified in the independent claims. Embodiments of the present invention are given in the dependent claims. Embodiments of the present invention can be freely combined with each other if they are not mutually exclusive.
According to an embodiment of the present invention, a radio receiver of an audio system receives a radio signal from a radio broadcast system. The radio signal includes a main signal and a radio data system (RDS) signal. The RDS signal includes one or more custom information associated with one or more media content tags, and each custom information is synchronized with a pre-determined time slot in the main signal. During a playing of an audio broadcast in the main signal, the audio system receives a given custom information in the RDS signal. The given custom information synchronized with a given pre-determined time slot in the main signal. In response to the given custom information, the audio system sends to a mobile device connected to the audio system a request comprising a given media content tag associated with the given custom information. The audio system receives from the mobile device, as response to the request, a targeted media content associated with a content identifier matching the given media content tag. The audio system plays the targeted media content, where the playing of the targeted media content is synchronized with the given pre-determined time slot in the main signal. This embodiment of the present invention solves the problem of synchronizing the playing of the targeted media content with pre-determined time slots in the main signal of the radio signal. This allows a radio broadcast system to offer targeted media content to be played at specific time slots during its radio broadcast.
In one aspect of the present invention, the mobile device is a primary mobile device. The media streaming service server collects global positioning system (GPS) data from a plurality of mobile devices over time. The media streaming service server identifies one or more common patterns in the GPS data that indicate a group of mobile devices traveling with the primary mobile device. The media streaming service server obtains profiles for the group of mobile devices. The media streaming service server identifies the targeted media content for the group of mobile devices based on the profiles, where the targeted media content is associated with the content identifier. The media streaming service server sends the targeted media content and the content identifier to the primary mobile device over an Internet connection.
In one aspect of the present invention, the media streaming service server determines that the GPS data does not meet a pre-determined accuracy threshold. The media streaming service server sends a request to the primary mobile device for proximity data. The media streaming service server receives the proximity data for a list of mobile devices from the primary mobile device. The media streaming service server revises the group of mobile devices based on the proximity data.
In one aspect of the present invention, in response to receiving the request for the proximity data from the media streaming service server, the primary mobile device identifies the list of mobile devices in proximity to the primary mobile device using a Bluetooth proximity discovery process. The primary mobile device sends the proximity data for the list of mobile devices to the media streaming service server.
In one aspect of the present invention, the media streaming service server determines that an Internet connection with the primary mobile device has fallen below a pre-determined threshold. The media streaming service server searches for an alternate mobile device in the group of mobile devices with an Internet connection above the predetermined threshold. The media streaming service server sends the targeted media content and the content identifier to the alternate mobile device over the Internet connection with the alternate mobile device.
In one aspect of the present invention, the alternative mobile device receives the targeted media content and the content identifier from the media streaming service server. In response, the alternative mobile device establishes a connection with the audio system.
In a second embodiment of the present invention, a radio receiver of an audio system receives a radio signal from a radio broadcast system. The radio signal includes a main signal and a radio data system (RDS) signal. The RDS signal includes one or more custom information associated with one or more media content tags. Each custom information synchronized with a pre-determined time slot in the main signal. A media streaming service server obtains a profile of a mobile device over an Internet connection, the mobile device being connected to the audio system. The media streaming service server identifies the targeted media content based on the profile, where the targeted media content is associated with the content identifier. The media streaming service server sends the targeted media content and the content identifier to the mobile device over the Internet connection. During a playing of an audio broadcast in the main signal, the audio system receives a given custom information in the RDS signal, where the given custom information is synchronized with a given pre-determined time slot in the main signal. In response to the given custom information, the audio system sends a request including a given media content tag associated with the given custom information to the mobile device. The audio system receives from the mobile device, as response to the request, a targeted media content associated with a content identifier matching the given media content tag. The audio system plays the targeted media content, where the playing of the targeted media content is synchronized with the given pre-determined time slot in the main signal
In a third embodiment of the present invention, a radio receiver of an audio system receives a radio signal from a radio broadcast system. The radio signal includes a main signal and a radio data system (RDS) signal. The RDS signal includes one or more custom information associated with one or more media content tags. Each custom information is synchronized with a pre-determined time slot in the main signal. A media streaming service server collects global positioning system (GPS) data from a plurality of mobile devices over time. The media streaming service server identifies one or more common patterns in the GPS data that indicate a group of mobile devices traveling with a primary mobile device connected to the audio system. The media streaming service server obtains profiles for the group of mobile devices. The media streaming service server identifies the targeted media content for the group of mobile devices based on the profiles, where the targeted media content is associated with the content identifier. The media streaming service server sends the targeted media content and the content identifier to the primary mobile device over an Internet connection. During a playing of an audio broadcast in the main signal, the audio system receives a given custom information in the RDS signal, where the given custom information is synchronized with a given pre-determined time slot in the main signal. In response to the given custom information, the audio system sends to the primary mobile device a request comprising a given media content tag associated with the given custom information. The audio system receives from the primary mobile device a targeted media content associated with a content identifier matching the given media content tag. The audio system plays the targeted media content, where the playing of the targeted media content is synchronized with the given pre-determined time slot in the main signal.
The RBS 112 offers pre-determined time slots during its audio broadcast to customers during which targeted media content can be played. The MSS 111 receives mobile device profile(s) through the MSA 107-109 at the mobile device(s) 104-106 over the Internet connection 121, identifies targeted media content based on the mobile device profile(s), and delivers the targeted media content over the Internet connection 121 to the MSA 107 of the mobile device 104 with the Bluetooth connection 122 with the HFU 103, referred to herein as the primary mobile device. Each targeted media content is associated with a given pre-determined time slot in the audio broadcast. The targeted media content is sent to the MSA 107 prior to the time slot, and the targeted media content is buffered at the primary mobile device 104. The targeted media content is played over the vehicle audio system 101 using the primary mobile device 104 as an audio gateway. In order to properly deliver the targeted media content, the start and stop of the playing of the targeted media content is synchronized with the associated time slot in the audio broadcast.
To synchronize the playing of targeted media content with the associated time slots in the audio broadcast, embodiments of the present invention leverages the radio data system (RDS) signal comprised in the radio signal 110. The RDS signal is a communications protocol standard for embedding small amounts of digital information in radio broadcasts.
In the above described manner, embodiments of the present invention solve the problem of synchronizing the playing of the targeted media content with pre-determined time slots (TS1-TSN) in the main signal 201 of the radio signal 110. This allows RBS 112 to offer targeted media content to be played at specific time slots during its radio broadcast.
Although the embodiments of the present invention are described herein in the context of an audio system in a vehicle, the synchronization of the playing of targeted media content with a radio signal may be applied to audio systems which are not in vehicles and which are capable of connecting to a mobile device such that the mobile device functions as the audio gateway.
In another embodiment of the present invention, instead of playing media content targeted to one given mobile device 104, the media content may be targeted to one or more mobile devices in a group of mobile devices. For example, the vehicle 100 may have multiple passengers, each with a mobile device 104-106. The mobile device 104 paired with the HFU 103 is the primary mobile device 104. By default, the MSS 111 is configured to identify media content targeted at the primary mobile device 104. Optionally, MSS 111 can instead be configured to identify media content targeted to a mobile device in the vehicle 100 other than the primary mobile device 104 or identify media content targeted to the group as a whole. To identify targeted media content for a group of mobile devices, the MSS 111 must first define the mobile devices that belong to the group.
In the above described manner, embodiments of the present invention solve the problem of synchronizing the playing of the media content targeted to a group of mobile devices with pre-determined time slots (TS1-TSN) in the main signal 201 of the radio signal 110. However, in certain situations, the accuracy of the GPS data may not be sufficient to reasonably identify common patterns. For example, two vehicles may be traveling in adjacent lanes on a road, and each vehicle has a group of passengers with mobile devices. The GPS data may indicate a common pattern between the group of mobile devices in the two vehicles, however, the density of vehicles on the road and the limits of accuracy of the GPS signal, may make it difficult to meaningfully determine whether this group of mobile devices are traveling in the same vehicle or are two different groups of mobile devices traveling in two different vehicles. In another embodiment of the present invention, when the common patterns do not meet the accuracy threshold (503), the MSS 111 sends a request to the MSA 107 of the primary mobile device 104 for proximity data (504). In response to the request, the MSA 107 of the primary mobile device 104 activates the Bluetooth proximity discovery process to identify a list of mobile devices in proximity to the primary mobile device 104 (505). The Bluetooth proximity discovery process, as is known in the art, is used to discover other mobile devices with the Bluetooth functionality turned on that are in close proximity. Once discovered, a piconet may be formed with the mobile devices in close proximity. Here, a piconet need not actually be formed from the proximity discovery process. The primary mobile device 104 sends to the MSS 111 the proximity data for the list of mobile devices, collected through the discovery process (506). Upon receiving the proximity data for the list of mobile devices from the primary mobile device 104 (507), the MSS 111 revises the mobile devices in the group based on the proximity data (508). The MSS 111 obtains the profiles of the mobile devices in the group (509) and identifies one or more targeted media contents for the group of mobile devices based on the profiles. The targeted media contents are each associated with a content identifier (510). The MSS 111 sends the targeted media contents, with the associated content identifiers, to the primary mobile device 104 in the group over the Internet connection 121 (511).
In another embodiment of the present invention, when the quality of the Internet connection 121 between the primary mobile device 104 and the MSS 111 falls below a pre-determined threshold, the MSS 111 may automatically, without user intervention, search for an alternate mobile device 105 in the group of mobile devices with the required quality in its Internet connection 121. When such a mobile device is found, the MSS 111 may automatically send the targeted media content to the MSA 108 of the alternate mobile device 105. In response, the MSA 108 of the alternate mobile device 105 may establish a Bluetooth connection with the HFU 103 so that the alternate mobile device 105 becomes the primary mobile device. The targeted media content received by the MSA 108 can then be played synchronized with time slots in the main signal 201 as described above.
