The user uses the wireless network device to receive and listen to a audio element of a broadcast and generate and transmit digital data to the programme broadcaster in interactive fashion. For example the broadcast programme may be a quiz show and the user listens to the questions from the broadcast and may send answers to the quiz questions from the wireless network device without being near a TV or radio. A WAP-enabled Internet site is hosted on a server (2) and is synchronised with the broadcast programme.
Description
lo. Interactive Audio system The present invention relates to the
apparatus and method for interacting with a broadcast program using a wireless device. The present invention relates particularly but not exclusively to the methods and apparatus for interacting with a TV or radio broadcast without requiring a separate TV or radio.
Interactive TV is known and requires a set-top box for the user to communicate with the broadcaster. The set top box provides the user with interactivity using a remote control unit. These conventional interactive broadcast (TV / radio) systems have restrictions and limitations; for example, additional equipment is needed, (e.g. a set top box) to receive and transmit the interactive program software, data and to superimpose the user interaction interface (graphics and text) on top of or alongside a broadcast programme are also required.
Because of these requirements, only a small proportion of the population have the facility to receive TV or other broadcasts in interactive fashion.
An object of the present invention is to alleviate at least some of the above disadvantages. In one aspect the invention provides a receiving arrangement for receiving a broadcast programme in interactive fashion, the arrangement comprising a wireless network device controlled by the recipient of a broadcast programme, the wireless network device being arranged to receive at least the audio element of the broadcast and having means to receive and display interactive data related to the said audio element of the broadcast, the wireless network device being arranged to generate and transmit digital data to the programme broadcaster.
Preferably the wireless network device is hand-held.
Preferably the wireless network device is a mobile telephone, e.g. a WAP phone. In other embodiments the wireless network device could for example be a pager, PDA.
palm-top computer or other device having the facility to communicate over a communications network such as the Internet or public telephone system.
Because the wireless network device is used in place of a conventional programme
! I ': receiver apparatus e.g. a television or radio, the user does not have to be near a TV or radio during a broadcast in order to interact with it.
The audio element from a broadcast transmitted to the wireless network device may be analogue or a digital; it may be compressed for faster transmission and /or to use less storage space. It may optionally be copy protected for the purposes of security. It may for example be streamed audio, i.e. played while being downloaded / received.
In another aspect the invention provides a programme transmitter arrangement comprising a programme transmitter arranged to broadcast a programme via a server coupled to the transmitter, the server being arranged in use to receive and transmit data related to the broadcast programme in interactive fashion from and to individual recipients of the broadcast programme.
Preferably the server is coupled to the Internet. Preferably the server is included in an arrangement for receiving WAP signals from programme recipients.
In another aspect the invention provides a method of interactive programme broadcasting wherein the recipients of the broadcast programme communicate individually with the broadcaster by means of wireless network devices.
Preferably the wireless network devices are WAP phones.
Most people do have a wireless device (e.g. mobile phone). Most of these users will, be in the near future, be upgrading their mobile phones; to be WAP (Wireless Application Protocol) enabled. Market research shows that there will be at least 100 million WAP phones in operation by the end of 2000.
The WAP mobile phone is a wireless device that has the ability to view, hear, access and interact with WAP enabled applications and services available on the Internet.
Just like Web pages on the Internet, WAP applications are written in a hypertext language and are available in the same manner and on the same computer servers (with some additional software) as Internet websites, and just like the Internet anyone with a WAP enabled device would be able to access a WAP website by typing in the web page address (e.g.www,. playalong.com\wap).
In one embodiment the invention provides a wireless interactive broadcast system that enables a user (i.e. recipient) to interact with a broadcast programme, normally available on a television, radio or other broadcast medium by using a WAP enabled wireless device that has the means to receive and play the audio element of a broadcast programme and the means to send, receive and display data interactive data related to a broadcast programme. The WAP enabled wireless device is preferably operable by the user to interact simultaneously with a broadcast and preferably the system includes means to compare said interaction with predefined interaction, e.g. answers to questions included in the broadcast programme.
l ó For the purposes of this specification the word interactive includes, but is not limited to
mean participate, play along, (game show/quiz), request (services/ goods), select, choose. The wireless device may for example be connected to or incorporated in a mobile phone, pager, PDA palm-top or any hand held device that has the means to display, send and receive data, (e.g. graphics and text) by means of a wireless communications.
The broadcast programme may for example be a game, game show, quiz, sports event, film, documentary, childrenis programme, advertisement or any broadcast programme a user could interact with.
In the case of a broadcast game show anyone with a suitable wireless device can listen and play along with the broadcast on his or her wireless device. The system may be arranged so that many players can compete against one another during a broadcast. In this case each player may be scored according to his accuracy and or speed of answering questions. Each playeris score may then be transmitted back to the broadcaster or game operator in order to find a winner.
. Players may for example be able to pre-book entry into a competition, wherein a short while before the broadcast begins the broadcaster send a SMS, page or other notification advising the player that a broadcast show is about to begin.
The wireless device may optionally have the means to restrict access to the interactive services by means of a PIN (personal identification number) or other access control system or combination thereof.
A preferred embodiment of the present invention will now be described by way of example only with reference to the accompanying illustration, which is a block diagram of the components and operable parts necessary to this particular embodiment of the present invention.
In one embodiment of the present invention a user of a WAP enabled mobile phone may be able to play along with a broadcast television quiz show. In order for this to be achieved, the questions and answers along with their time-codes (time lapsed from beginning) in the broadcast quiz show, would need to be available prior to the broadcast, for creating a WAP enabled interactive application of the broadcast quiz show, which would be simultaneously, available on a WAP enabled Intemet website, as the broadcast.
A unit of the example depicted comprises a wireless device 1. In this example the wireless device is a WAP enabled mobile phone which provides the user with the means to receive and listen to a broadcast programme, and to view and interact with a WAP enabled application. The arrangement further comprises a WAP enabled Internet server 2 to host the said broadcastis WAP application, a wireless transceiver 4 to allow
the WAP enabled wireless device 1 to connect, send and receive data and audio from the WAP enabled Internet sever 2. A broadcaster 3. provides the audio element and the interactive data for the quiz show to the WAP server 2. or directly to the wireless device 1. This may be by means of a satellite, terrestrial, cellular, microwave or any other means of wireless transmission.
In this embodiment of the invention the user input and interacts by selecting the appropriate buttons by means of a keypad on the WAP enabled wireless device 1.
When a user of a WAP enabled wireless device 1 wants to interact or play along with the WAP enabled broadcast, in this example a quiz show; he inputs the Internet address of the quiz show's WAP enabled website on his WAP enabled wireless device 1. The WAP enabled wireless device 1 then connects to the wireless device transceiver 4, which then connects the user to the quiz showis WAP enabled Intemet website on the WAP enabled internet server 2.
Previous to the broadcast of the quiz show, the questions and answers along with their respective time-codes (time lapsed from the beginning), would be needed prior to the broadcast, so that a time coded WAP enabled internet application of the broadcast quiz show could be created. This would then be running on the WAP enabled Internet server 3. simultaneously with the broadcast of the quiz show. Hence, as the questions are announced on the broadcast quiz show, they simultaneously appear on the display of the WAP enabled wireless device 2. These questions may be available to the user as a multiple-choice interface, and as the answers are announced on the broadcast the user's selections are scored according to their accuracy.
When the broadcaster 3 starts to broadcast the quiz show, the broadcaster 3 sends the audio element from the quiz show along with a signal to the WAP enabled Internet server 3 to simultaneously play the audio element of the broadcast and run the broadcast related interactive WAP application; in this case the questions in the quiz show, on the WAP enabled Internet server 3. The broadcast and the Interactive WAP application run simultaneously and synchronized.
As the questions become available to the general public by means of a TV or radio broadcast the audio element and the interactive questions are simultaneously played and displayed on the useris WAP enabled wireless device 1. via the WAP enabled Internet server 2 He may then answer the questions, which may be presented to him in a multiple-choice format.
In another embodiment of the present invention the complete WAP enabled application with / without the audio element of the broadcast may be downloaded to the WAP enabled wireless device 1 prior to the broadcast. In this case the broadcaster would send a signal to the WAP Internet website instructing it to send a signal to the WAP enabled wireless device to begin the application, thereby synchronizing it with the broadcast.
l ( In another embodiment of the present invention the WAP enabled application may be download in sections, in this case, each time a section of the application is downloaded it is synchronized with the broadcast. This may happen at predefined time intervals in order to keep the WAP server synchronised with the broadcast.
Yet in another embodiment of the present invention the broadcast may be a radio broadcast. This invention is not limited to WAP as new means of wireless communications are being developed which will become available. Therefore consideration should be given to NTT DoCoMo's, IMode or the like, which are excellent WAP alternatives. Other new wireless communications that may be used include, but are not limited to, packet based wireless communications which will be introduced soon e.g. packet switched GPRS (GSM packet radio systems) and later Universal Mobile Telecommunications systems (UNITS).
These advances in wireless communications will mean faster data retrieval and transmission, with constant and immediate two-way data communications (On-always) which do not need to make a dial-up link every time data is sent or received.
: Therefore in another embodiment of the present invention a user of a wireless device with any one of the next generation of wireless communications, may have the means to interact with a broadcast, anytime without having to make a connection every time information or an interaction is required. In this case the broadcasters may by-pass the use of the Internet (WAP) and communicate directly with the wireless device.
In another example of the present invention advertisements may be displayed on a user's wireless device. These may for example be synchronized with broadcast advertisements or may be available independently (like banner advertising on the Internet). This feature could create a revenue stream for the operator (especially with the next generation of (On-always) wireless communications).
The interactive advertisements available on the wireless device may be arranged so that a user may be able to purchase goods and / or services from a broadcast advertisement. The means to download vouchers may also be incorporated, i.e. if you watch / interact with an advertisement, a 25% off voucher is downloaded to your wireless device. This may then be printed off or redeemed by an electronic means (e.g. Bluetooth).
