  • the "in” and "out” positions in the digitized video corresponding to the message are counted automatically and are also stored to the database shown in Fig. 4 (Step 240) .
  • the SMIL standard is used to describe the beginning and ending of the video clip.
  • the reporter's input and video recording are thus functionally integrated to form a video with expert comments that can be easily distributed only a few seconds after the event actually happened (Step 250) . It may be distributed in any number of ways. For example, it can be broadcast, multicast, made available for downloading from a central location, etc.
  • Application server 130 combines the video and message in synchronization according to the timestamps prior to forwarding it. Although only the Internet is shown in Fig. 1, it is understood that communication networks provide communication services between monitor 140 and mobile terminal 150. Because the video in the server is digitized all the time, any video segment is immediately available for Internet users.
  • Monitor 140 can be any type of display, for example, a television or computer monitor, including flat panel type displays. In any event, it preferably includes a plug-in PIP module. Most monitors that incorporate PIP and other features also include a microprocessor control which, via a suitable control bus, periodically interrogates certain functional blocks and modules in the chassis to determine whether they are present and, if so, to control their operation. In the case of a PIP module, polling by the microprocessor indicates whether the module is present. If it is, the microprocessor arranges to switch the composite video signals (from any tuner and external sources) through the PIP processor and then to the main video processor of the monitor, in preference to the normal composite video produced. Thus, the video processor of the monitor has its inputs supplied from either the main chassis in the event there is no PIP module or from the PIP processing module.
  • the mobile terminal 150 can be any type of unit capable of receiving and displaying signals. For instance, it may be a cellular phone with a small display, an Internet appliance with web browser capability, a handheld computer or a laptop computer. In any event, it preferably has PIP functionality as well. This functionality allows the user to simultaneously view two applications in the display.
  • the applications can be, for example, the video segment with interlinked message as described herein in one window and an interactive betting service involving the game in another window.
  • the interactive betting service can be web-based and personalized so that pages of interactive content can be configured by said client terminal to display pertinent information information according to the preferences of the client terminal and the interactive content is tailored to the transmission and reception capabilities of the client. A description of the interactive betting service can be found in the realted patent applications incorporated herein by reference.
  • the monitor 140 and mobile terminal 150 receive an integrated digital broadcast signal (DVB-T) . Reception of the signal can be accomplished through various means.
  • the mobile terminal receives the signal over a GSM, GSM++, POTS, UMTS, or other type of connection 145.
  • the mobile connection 145 itself may be connected to a network such as an extranet, intranet, or the Internet.
  • Mobile connection to applications server 130 takes place in a conventional manner over a modem pool with user dial-in and authentication services.
  • intermediate protocols and network connections may not be required to achieve connection.
  • the flowchart of another possible process is illustrated in Fig. 3.
  • the cameras record the entire game and digitize the content for later use (Step 310) .
  • the commentator marks the time when something interesting happens (Step 320) . Specifically, he sends the time-mark of the interesting happening as an "in” information to application server 130. Then, he writes a short expert comment, preferably in the form of text (Step 330) .
  • the commentator sends the message to application server 130 and, when the interesting scene ends, marks the ending time of the interesting happening (Step 340) .
  • Application Server 130 receives the data (Step 350) , processes it with the time-mark information and makes it available for subscribers via the Internet (Step 360) .
  • the time marks aid the server to operate correctly. When the time mark is "in” the server links the expert comments and the video clip together. When the time mark is "out”, the linking ends.
  • Application server 130 can then offer the file to subscribers (Step 370) .
  • video and audio streaming of the game may be accomplished, in the presently preferred embodiment, with a live video/audio streaming server (VAS) transferring the whole game through a network such as an extranet, intranet, or the Internet or through an RF receiver at the server, where comments are added.
  • VAS live video/audio streaming server
  • the audio can be digitized using one of several digital compression schemes, for example, H.728, H.729, or GSM.
  • the digitized video can be compressed using a scheme such as MPEG, MVC, H.261, etc.
  • the digitally compressed audio and video are packaged for network transfer e . g. , TCP/IP, UDP and then broadcast to the network controlled by a streaming/multicasting controller.
  • An interactive application of intermittent video clips with accompanying messages may be preferable in may circumstances, especially when the client is simultaneously supporting another interactive application, such as a betting service which is described in detail in the related applications incorporated by reference.
  • An interactive application is an "action list" of interesting happenings in all the games played at the same time.
  • a line indicating the happening appears on the list.
  • the line may include one sentence describing the action and the time of the happening.
  • the happenings in a video message sending system can be linked to, for example, an interactive betting service which is simultaneously displayed or active in a window or PIP capability of a terminal device when the happening occurs.
  • applications server 140 can store any links from video clips to other applications, such as an interactive betting application. Details of an interactive betting application are provided in applicant's related patent applications incorporated herein by reference.
  • the link can be set by the betting application in the client terminal notifying the applications server that the user has bet on Jokerit-Tappara game for example or has bet that Gretzsky will score when at the time the bet is placed.

  • the video signal can be automatically forwarded to the client terminal or an observation or other notification can be provided to the client. Moreover, the video signals and the betting information can be compared at any time or for any reason to determine if the action has happened. Since the video clip with identification "froi2345" is a clip of Gretzky scoring in the Jokerit-Tappara game in the example of Fig. 4, the video clip can be automatically forward by applications server 130 to the client terminal .
  • Such events can include, for example, video games, shopping, and educational activities.
