  • Teletext Teletext
  • One solution is to interrupt the current broadcast, and temporarily broadcast the match where the goal was scored. However, the user may not want the current program to be interrupted, or may prefer not to see the other broadcast right now.
  • Another approach is to gather, at an external server for all users, subscriptions to or other indications concerning respective occurrences, monitor the event being broadcasted for the subscribed-to or indicated occurrences, and selectively distribute notifications of detected occurrences to the respective users. The users can then switch to the particular channel or be switched there automatically.
  • the user discloses private information when selecting or otherwise specifying an occurrence of interest.
  • This data reflecting preferences of the viewing public, is valuable not only to the broadcaster and content provider, but to anyone seeking to sell goods or services to the viewing audience. Yet, the viewer might want to avoid receiving unsolicited advertising targeted to perceived preferences of the viewer. It is possible, also, that selections the user has made in subscribing to certain occurrences are selections the user wants to keep confidential.
  • the broadcaster or its service provider may maintain a policy of keeping the subscriptions confidential, the remoteness of the server affords the possibility of unauthorized physical access.
  • Servers typically are connected or connectable to user interfaces, through which a hacker may gain access to the personal information. If the hacker obtains a counterfeit badge, for example, and thereby gains entry to a restricted location where the server is kept, the server may be hacked, and personal information of the view could be revealed.

  • the combination of the STB 216 and the TV 224, or merely the TV if the configuration excludes the STB, may include more than one tuner, so that the user may view his current channel uninterrupted while an occurrence of interest on another channel is being recorded to memory 320.

  • the subscriber may pick, from a menu provided by the broadcaster, an occurrence to thereby subscribe.
  • a particular occurrence may be selected by the subscription module 320 automatically based upon user preference it gleans from monitoring behavior of the user. This behavior may include interaction with the CE device 310, e.g., changing channels, query-and-answer sessions using the remote control 228.
  • the CE device 310 can include monitoring equipment such as a camera and/or microphone, and visual pattern/voice recognition facility, to glean user preferences. For instance, certain gestures by the user may be commands indicating appreciation or lack thereof in connection with a just seen program or commercial, or involuntary behavior may be interpreted.

  • Private packets in the case of a digital broadcast, or Teletext in the case of an analog broadcast, can be monitored in the received signal 212 to detect notification that a subscribed-to occurrence has been detected (step S504).

  • each notification message has an identifier of the occurrence.
  • the comparison unit 340 reads the identifiers in the recorded subscriptions from memory 325 and matches them against identifiers in the notification message (step S516). Non- matching portions of the notification message are thereby filtered out. If any portion is not filtered, i.e., due to a match (step S520), the processing section 350 decides on how to proceed. The user may be notified (steps S530, S540), as by the appearance of an icon on the viewing screen of the TV 224.
  • Clicking on the icon, using the remote control 228, can switch the user to the channel carrying the broadcast 212.
  • the broadcast 212 is processed to extract, for viewing, the occurrence identified in the matching (steps S550, S560).
  • Notification to the user alternatively, may be in the form of a small picture in a TV 224 with a picture-in-picture (PIP) capability.
  • PIP picture-in-picture
  • the user then uses the remote to dispense with the small picture or enlarge it.
  • the user can be switched automatically, without prior notification, to the channel carrying the occurrence.
  • recorded subscriptions contain respective priority values or ranks.
  • Sufficient value or rank in comparison to that accorded the currently viewed program, or competing subscribed-to occurrences concurrently being notified in the incoming broadcast 212, can determine how notification and/or automatic channel switching is currently performed. Thus, if one currently detected occurrence outranks another currently detected occurrence, in terms of user preference indicated by the user or otherwise gleaned, the outranking occurrence is notified to the user and/or appears onscreen. As a further alternative, the occurrence may be recorded to memory 325, rather than presented, so that the occurrence can be played back later at the viewer's convenience. Ranking may also be applied in deciding which of competing concurrent occurrences to record. In the case of two tuners, the recording can be performed while the user is using one of the tuners to continue to view the current channel.
  • FIG. 6 portrays an embodiment alternative to the broadcast and message receiving and processing embodiment of FIG. 2.
  • the broadcasted signal 212 is typically concurrently received by numerous users.
  • FIG. 6 shows, for simplicity of illustration two televisions 610, and their respective remote controls 620, comprising a receiving system 630 for viewers.
  • the television 610 here is the CE device 310, and is not connected to a set-top box. Instead, the televisions 610 retain the user subscriptions, on having a subscription to occurrence A, the other having subscriptions to occurrences A and B. Accordingly, the televisions 610 filter the notification message differently, according to their respective recorded subscriptions.
  • the televisions 610 are receiving an analog broadcast, and have no interaction with the infrastructure 204, 208.
  • the user is provided with automatic notification and/or channel switching, relating to immediately-current occurrences in live events, based on user preference, but is afforded more assurance that the preferences are kept confidential.

Abstract

La présente invention concerne des occurrences spécifiques correspondant à des préférences d'un utilisateur qui sont souscrites et enregistrées (216, 228, 320). Un signal diffusé (212) transportant un événement en direct surveillé pour une occurrence souscrite est reçu. En cas de détection de l'occurrence, un message de notification est reçu (S504). A ce moment-là, une comparaison est effectuée entre le message reçu et les occurrences enregistrées pour filtrer tout ou partie du message en fonction d'une absence de concordance entre les occurrences enregistrées et le contenu du message (S516, S520). L'utilisateur peut être averti ou le signal diffusé peut être traité en cas de concordance (S540), voire les deux.
