Intellectual Properly Office is an operating name of the Patent Office www.ipo.gov.uk Radio Receiver System
FIELD OF THE INVENTION
The present invention relates to a radio receiver. In particular, the invention relates to a radio receiver system suitable for delivering rich-media content associated with a broadcast radio signal where the broadcast radio signal comprises at least an audio stream.
BACKGROUND OFTHE INVENTION
Users are increasingly wanting multi-media or rich-media experiences when receiving media. For example, a user may want to know additional information relating to a TV or radio program being broadcast.
In radio, the DAB standards include the specification for an MOT Slideshow application which delivers a series of static bitmap images to a receiver over the broadcast channel and an Electronic Programme Guide application which delivers additional programme information. This provides the user with a richer-media experience over the standard audio radio broadcast stream, although this mechanism is not without its limitations (namely in the content that can be delivered due to bandwidth restrictions in the broadcast stream).
An alternative is the RadioVIS specification from the RadioDNS organisation, which describes a method of associating a broadcast radio service with an internet service that delivers visual content to provide a rich media experience.
RadioVIS has been implemented on relatively expensive hybrid devices that include a broadcast receiver, a graphical display and an internet connection. However, these are dedicated, expensive devices.
The cost of providing an internet connection and a graphical display in such a hybrid radio device is quite significant compared to that of existing low-cost broadcast radio receivers typically used in the home.
We have therefore appreciated the need for a more cost-effective means of delivering a rich-media experience to a user.
SUMMARY OF THE INVENTION
The present invention therefore provides a radio receiver system for delivering rich-media content associated with a broadcast radio signal, the broadcast radio signal comprising at least an audio stream, the radio receiver system comprising: an antenna interface having an input coupleable to an antenna for receiving a broadcast radio signal, and an output for outputting the received broadcast radio signal; a receiver unit having an input coupled to the antenna interface output to receive the broadcast radio signal, the receiver unit being configured to extract an audio stream from a received broadcast radio signal and to generate a data stream from a received broadcast radio signal, and the receiver unit having an output for outputting the audio stream and the data stream; a data interface having an input coupled to the output of the receiver unit for receiving the data stream, and an output for outputting the data stream generated from the received broadcast radio signal; and a removable display coupleable to the data interface for receiving the data stream, wherein the removable display, when coupled to the data interface, is configured to access rich-media content stored on a content server in response to the received data stream, the rich-media content being associated with the broadcast radio signal, and the removable display being configured to display the rich-media content on the removable display.
Advantageously, by using a removable display coupleable to the data interface, items already owned by the user that are suitable for the purpose of receiving and displaying such rich-media content can be used in place of a dedicated integrated screen and integrated internet functionality in the radio receiver. This keeps costs down, since no screen and internet-connectivity is required in the radio receiver.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The cost ol providing an internet connection and a graphical display in a device to enable a rich-media experience (br example a hybrid radio device comprising a graphical display) is quite significant compared to that of existing low-cost broadcast radio receivers typically used in the home.
However, many consumers have other existing devices such as smartphones, laptops, tablet computers and Internet TVs which have an internet connection and a graphical display but lack a broadcast radio receiver.
In brief, the invention describes a means for delivering rich media services using a broadcast radio receiver that lacks a graphical display in conjunction with a separate internet-connected display device such as a smartphone, laptop, tablet computer or Internet TV.
This invention describes a way for a broadcast radio receiver to communicate information about the selected radio service to a separate internet-connected device via a communications link such as a P5232, 120, Bluetooth, WiFi, Ethernet or USB.
The separate device then requests the associated rich media content via its internet connection and presents it on the graphical display.
When used together in this way, the user is presented with an integrated rich-media experience in which the audio is presented via the broadcast reception device and the visual content is presented via the internet-connected display device using a very cost-effective setup.
Advantageously, this provides a way of delivering hybrid radio services on a digital broadcast receiver without the expense of a dedicated internet connection and graphical display on the receiver.
Figure 1 shows an overview of a system. A broadcast receiver (100), such as a DAB radio, comprises a receiver module chipset (102) coupled to a broadcast radio antenna (104) for receiving broadcast radio signals and a display (106) for displaying basic information regarding the radio station being listened to via the speaker (108). Signals are broadcast over a broadcast network of transmitters (132) from a radio studio or broadcaster (130).
Ordinarily, the radio signal being transmitted from the radio studio is received by the broadcast receiver antenna (104), passed to the receiver module chipset (102) for mixing and/or decoding to a signal suitable for passing to an audio amplifier for listening, and a data signal comprising additional data (for example basic information relating to the channel or any basic data relating to the programme being received) is passed to the receiver's display (106).
As well as providing audio and basic data via the broadcast stream, broadcasters (130) pass rich-media content (for example additional music, pictures, videos, write-ups and other such data) to content server (128) attached to the internet (124).
In the present invention, the radio receiver provides a data stream comprising station data defining a station identifier associated with the station transmitting the broadcast radio stream and other station and programme-specific data received from the broadcast transmitter. The data stream is output via the data interface to an internet-enabled device (112, 116). The data stream may comprise data extracted from the broadcast stream, and/or data generated from receipt of the broadcast stream (for example the frequency used to receive the broadcast stream).
The RadioDNS standard uses various pieces of information to identify the station being received, which is dependent on the broadcast standard. For FM, for example, a station can be uniquely identified by a combination of FM Frequency, RDS P1 Code, RDS Country Code and RDS Extended Country Code. For DAB, the information used may be a combination of Ensemble ID, Service ID, SCIdS and Extended Country Code.
The internet-enabled device is connected to the internet (124) via a suitable router and/or modem (120). The internet-enabled device may comprise a smartphone, laptop, tablet computer or Internet TV or other such device. In the case that the internet-enabled device is a mobile phone or smartphone, the connection to the internet (124) may be via a 30 or 40 connection (or other suitable mobile device communication protocol) instead of via a modem/router (120).
The radio receiver is connected to the internet-enabled device via a suitable wired or wireless connection such as Ethernet, RS232, l2C, Bluetooth, WiFi, USB or other such connection.
In the embodiment shown, the internet enabled device (112) sits in a docking station (116), which is connected to the radio receiver (100). For example, the docking station (116) may comprise a fitting to accept an iPhone or iFad or other such smartphones and tablet-like computers.
In alternative embodiments, the radio receiver (100) is connected directly (again either via a wired or wireless connection) to the internet-enabled device.
Station identifier data (as discussed above) and other data are passed to the internet enabled device, which uses this data to seek out and retrieve rich-media content associated with the station currently being received on the radio receiver, or content associated with the specific programme being received. This data is pulled over the internet (124) via the modem/router (120) from the content server (128) on the broadcast side. The rich-media content is then displayed on the internet-enabled device.
When the station is changed, or the programme on the station being received changes, the rich-media content will change dependent on the station and/or programme data being received by the radio receiver and passed on to the internet-enabled device.
One application of the above invention is in a speaker dock for a smartphone such as an iPhone or a tablet device such as an iPad.
Existing speaker docks often have a DAB or FM broadcast receiver built into them for use while the docked device is charging. Using this invention, the smartphone or tablet device can be used to obtain and present rich-media content associated with the radio service being received on a broadcast receiver built in the speaker dock.
This would enable rich media radio services to be delivered to consumers in a very cost-effective way and stimulate demand for devices capable of doing this.
Although the present invention has been described hereinabove with reference to specific embodiments, the present invention is not limited to the specific embodiments and modifications will be apparent to a skilled person in the art which lie within the scope of the present invention. Any of the embodiments described hereinabove can be used in any combination.
