Definitions

  • This invention relates to communications systems, and in particular to systems which integrate broadcast and interactive services.
  • a feature of modern digital broadcast services is the provision of supplementary data or associated channels, accessible in response to a user input which causes the supplementary data to be displayed instead of, (or as well as), the original channel.
  • Such data may include subtitles, additional information on a particular item in a broadcast etc.
  • viewing such additional data at the time of transmission can disrupt the viewing of the main broadcast programme.
  • the present invention provides a system by which supplementary information can be accessed subsequent to the broadcast programme. Some embodiments also allow the information to be retrieved even if the programme is not viewed at the time of broadcast but as a recording.
  • the present invention adopts a different approach, which avoids the need to modify the broadcast content.
  • communications units which, in addition to accepting input data from a broadcast service (e.g. through a standard television aerial) also has a connection to a data communications network such as the Internet.
  • a data communications network such as the Internet.
  • Such systems use the data communications network for download of additional services such as electronic programme guide (EPG) data.
  • EPG electronic programme guide
  • the data communications network connection is bi-directional, so it can also be used for services requiring an uplink, such as "on-demand" streaming services.
  • Input from both sources (broadcast and internet) is converted by the communications unit to a form suitable for display on a monitor device, typically a standard television receiver.
  • the communications unit is typically controlled by a remote-control unit.
  • a communications terminal for processing data, the terminal comprising a receiver for receiving broadcast content, a transmitter for transmitting a request for supplementary data, a control input for receiving control signals, and a processor for identifying the content currently being received by the receiver, generating a request for content associated with the current received content to be transmitted to a predetermined address, and transmitting the generated request to a predetermined content provider.
  • a complementary aspect which provides a content provision processor having a data comparison processor for identifying a concordance between broadcast content and supplementary data associated with the broadcast content, an input for receiving data requests from one or more client devices identifying broadcast content and a return address, a retrieval system for retrieving the supplementary data associated with the broadcast content identified in such requests, and a transmission system for transmitting the retrieved supplementary data to the return address specified in the request.
  • the invention also provides a method of retrieving supplementary data associated with a broadcast transmission by identifying the broadcast content currently being received at a receiver, generating a request for data, the request including the identity of the broadcast content, transmitting the request to a content provision processor, at the content provision processor retrieving supplementary data associated with the identified broadcast content and delivering the supplementary data so identified to a predetermined return address.
  • broadcast content is used here to mean any content made available to a large number of receivers, either simultaneously or on demand. If the content is transmitted and viewed in real time, the identification of the broadcast content for which supplementary data is required can be made by identifying the channel currently being viewed and the time of the request, the concordance then being made with the transmission schedule of the channel in question.
  • the identification of the content for which supplementary data is required would require not only the channel but the exact start time of the recording to be captured, as well as the point in the recording which has been reached.
  • the content can instead be identified using "acoustic fingerprinting", in which an extract of the content is recorded and transmitted to the platform to identify the content in question. This could, for example, be a distinctive sound track such as an advertising jingle. This method would allow content to be identified when viewed "on demand", or as a replay of a recording made by the user.
  • the user may be given the option of requesting data on content that has been transmitted recently, rather than at the instant of the request. This allows time for a user to react to the advertisement of other content, and locate the control device.
  • the request generation processor may adjust the time specified in the request, or the segment of transmission to be used for acoustic fingerprinting, accordingly.
  • the time delay may be incorporated in the request, and allowed for in the processing at the remote platform.
  • the supplementary data may be transmitted to a user device other than the communications terminal on which the main content is received.
  • a user device may be in the form of an email or text message giving access details (such as a website address) for more detailed content.
  • a user terminal (2 or 3) has an input 26 from a source 6 of transmitted material.
  • this input 26 is a television aerial for receiving transmissions broadcast from a content provider 5 through a transmitter 6 (terrestrial or satellite).
  • the input may instead be from a cable TV service.
  • the input may be material played back from a recording device, which has previously recorded the material from a broadcast source. As is conventional, the material is displayed on a television set 1.
  • the user terminal (2 or 3) also has a data connection through a router 7 which acts as the interface between user equipment 2, (3), 9 and a data communications network 8 such as the Internet.
  • FIG. 1 Also shown in Figure 1 is a service provision platform 4 accessible from the data communications network 8. This platform has a data feed from the content provider 5.
  • Figure 2 depicts a first embodiment of the user terminal 2 depicted in Figure 1 .
  • This has the conventional functions of a digital television "set-top box", in particular a channel selection unit 20 controlled by a user input 22, shown as controlled by a remote control unit 21.
  • Some devices of this type also have a connection 7 to a data communications network 7, to allow services such as on-demand video streaming, electronic programme guides, etc.
  • the present invention makes use of this connection for a further capability, embodied in an information request generation unit 23.
  • This unit is responsive to an input from the user 21 to retrieve data relating to the content currently being viewed and transmit this data to a remote server together with an address for response retrieved from a store 27.
  • the content may be identified from the current status of a channel monitoring unit 24, which is controlled by the channel selection unit 20 to identify the television channel currently being viewed, and the time the request is made as determined by an internal clock 25.
  • the control 21 may allow an input to identify a time to be calculated other than the current instant, for example 30 seconds previously.
  • the control 21 may also have provision to control the request generation unit to select one response address from several stored in the address store 27.
  • Figure 3 is a schematic diagram of an alternative user terminal 3 which may be used in place of the user terminal 2 shown in Figure 2 .
  • the components 20, 21, 22, 26, 27 common to the embodiments will not be discussed again in detail.
  • the request generation unit 33 is responsive to the input 22 to operate a sampling unit 34 to extract a sample of the content being delivered to the user 1.
  • the sampling unit 34 may incorporate a buffer to allow content recently viewed or heard by the user to be used.
  • the sample is coded to an acoustic fingerprint or "tag" such as used by the music discovery search engine "Shazam", and the tag forms part of the request to be transmitted by the request generation unit 33
  • Figure 4 illustrates the functional elements required at a service provider's platform 4 suitable for co-operation with the user terminals of both Figures 2 and 3 . Although depicted as a integrated unit the various functional elements may be distributed amongst several items of hardware, and may be duplicated for capacity or reliability.
  • the platform 4 has a store 45 for supplementary data provided through an interface 46 with one or more content providers 5.
  • the platform 4 also stores the broadcast schedule 42 in sufficient detail that it can identify which content is currently being broadcast at the point that a request for supplementary data was generated. If the primary broadcast content is advertising material, this requires a schedule of the advertisements transmitted in he broadcast.
  • the platform 4 also has an acoustic fingerprinting processor 43 for identifying content from a sampled extract. It will be apparent that the functional elements 42, 43 are specific to the request types generated by the respective user terminals 2, 3 depicted in Figures 2 and 3 , and either of them can be omitted if the platform is intended for use only with the other request type.
  • the platform 4 has an input unit 40 connected to a data communications network 8 for receiving information requests from user terminals 2, 3 connected to the network. This input is analysed by a broadcast identification unit 41 which identifies the primary content being viewed at the time the request was made, either from scheduling information (42) or from content analysis (43). A supplementary data retrieval unit 44 is controlled by the broadcast identification unit 41 to retrieve content related to the identified content. This content can be a universal resource locator (url) or Internet address giving access to more comprehensive data.
  • url universal resource locator
  • An addressing unit 47 is provided to extract return address data incorporated in a request received at the input 44.
  • a reply compiler 48 generates a reply, for example in the form of an email, addressed to the return address retrieved by the addressing unit 47 and containing the data retrieved by the supplementary data retrieval unit 46, and transmits it through a data communications network - generally, but not necessarily, the same network 8 as that over which the request was received.
  • a viewer 99 seeing an item of interest 500 on the television 1 may wish to have more information than is contained in the transmission. For example, a short advertisement may prompt the viewer to seek further details. There is no need to overlay any metatags or other extra data in the broadcast content, although the content of the advertisement may of course mention that users who have the invention installed in their user terminal can seek further details by using the method of the invention.
  • the further information is available at a location 45 in the platform 4 operated by the service provider.
  • This data is typically an email address or url (universal resource locator) for the advertiser's website.
  • the user can have confidence that he is not exposing himself to unknown or unfamiliar websites, and after receiving the contact details he can review them before deciding whether to establish contact with the advertiser itself.
  • content 45 is provided by the user's service provider, content can also be tailored to individual users, for example by providing a variant appropriate to the user's address or preferred language, or by barring access to inappropriate sites if the user has requested such a restriction.
  • control unit 21 In order to obtain this information, the user 99 operates a special key or sequence of key strokes on the control unit 21 (step 501). As shown in Figure 2 , this is the same control unit 21 that controls functions such as channel selection 20, but separate control units may instead be provided for these different functions.
  • control unit In response to the keystroke or sequence of such strokes the control unit transmits a control signal 502 to the request generation unit 23.
  • this control signal 502 simply causes the request-generation function (503, 504) to be initiated.
  • more complex requests may be made available, for example to select between the current and previous advertisements, or to allow different viewers to have content sent to different respective addresses 9.
  • the generation of more complex requests may be assisted by prompts generated by the user terminal 2 for display on the television screen 1.
  • control units 21 may be provided, each associated with a different address 9 and each capable of sending request signals 501 which can be distinguished by the request generation function 23.
  • the operation of the request-generation unit 2, 3 differs in the two embodiments.
  • the operation of the embodiment of Figure 2 is illustrated in Figure 5
  • the steps 593, 594, 595 illustrated in Figure 5a replace the steps 503, 504 delineated by the box in Figure 5 .
  • the request generation unit 23 interrogates the output 24 from the channel selection unit 20 (step 503), and also identifies the current time (step 504) from an internal clock 25.
  • the clock may. itself be driven from a broadcast source 26. This information therefore identifies the time and channel on which the primary content was transmitted. As mentioned previously, the time can be adjusted, for example to identify the previous advertisement rather than the current one
  • the user terminal 2 may be capable of recording the channel and start time of recordings that it makes, and this data may be used to generate similar requests during playback of the recording by calculation of the original time of transmission of the part of the recording that was being viewed when the user operates the control (501).
  • Figures 3 and 5a illustrate an alternative method of generating requests for supplementary information.
  • the request generation unit 33 transmits an instruction (593) to a sampling unit 34 to take an extract from the content currently being delivered to the television screen 1.
  • a buffering facility is provided so that the sampling unit can extract the content that had been transmitted immediately before the user 99 generated the request 501, 502.
  • the buffering period may be adjusted to allow material from either the current advertisement or a previous one to be extracted.
  • the sampling unit 34 generates a sound file 594 which is returned to the request generation unit 33.
  • the request generation unit 33 now compiles a data request 506. This includes the data identifying the primary content (either channel and time, 503, 504) or sound file (594), and the address to which the data is to be sent, retrieved from the address store 27 (step 505). As indicated previously, the input 502 may indicate which of several addresses is to be used, and also may indicate whether the requested data is for the actual time or for a preceding segment in the broadcast.
  • the data request 506 is transmitted over the data communications network 8 to the service provider platform 4.
  • the service provider platform responds to such data requests as follows.
  • the request includes data identifying primary broadcast content and an address to which a response is to be sent.
  • the content data 507 may be channel and time data (see Figure 2 ) or a. sound clip (see Figure 3 ).
  • This is forwarded to an analysis unit 41, which interrogates a database 42 or 43 (step 508).
  • the database 42 matches time and channel data to the original television schedule (supplied to the service provider 4 from the broadcaster 6) to identify the content that was being transmitted at the specified time - or immediately preceding that time if the request so specifies.
  • the database 43 performs an "acoustic fingerprint" process to identify the content.
  • the fingerprint may be a "jingle” or a readily-identifiable trade mark or strap-line.
  • the platform 4 then passes the request to a retrieval unit 44 (step 509) to retrieve the supplementary data associated with it (step 510).
  • the supplementary data is maintained in a store 45 to which content is delivered either by the service provider or by the various content providers 46. This supplementary data typically consists of a link to the advertiser's website.
  • the supplementary data is delivered (step 511) to a message compiler 48 which generates a reply 514 to the original data request 506.
  • this reply is a message addressed to the user's email address 9, identified in an addressing unit 47 which retrieves the user identity from the input 506 (step 512), converts it to a user address 513 which it passes it to the message compiler.
  • the message contains the supplementary data 511 retrieved from the store 45.
  • the message complier 48 may tailor this message to the individual customer according to details held on the service provider's own customer database, such as location, content restrictions, etc.
  • the complied message 514 is then transmitted over the data communications network 8 to the user address 9 specified in the address header 513.
  • the destination user address 9 is served by the same network interface router 7 as the user terminal 2 from which the request is transmitted, but this is not limitative - the destination can be any internet address specified by the user.
  • the message 514 can then be viewed by the user 99 (step 515) at a time and place convenient to him without interrupting his own viewing of the original programme content 500, or the viewing of anyone else watching with him, and can choose whether, and when, to download the content available at the advertiser's url.
