In this way, the television viewer may receive additional information related to the television program. That information may be stored on the user's associated computer system for subsequent viewing.
  • a method for receiving a video transmission includes identifying a tag associated with a first video transmission. Upon selection of the tag, the information related to the tag is stored. A second video transmission is scanned for information associated with the tag.

  • the RCU 16 may include a set of left and right and up and down arrow keys 18 and a selection key 19 which enables a pointer "A" to be moved across a video display screen, for example associated with the television receiver 12. In this way, the cursor or pointer A may be moved using the arrow buttons 18 and various selections may be made on associated graphical user interfaces using the button 19.
  • the RCU 16 may also include a plurality of keys 20 to enable other user selections such as channel selections.
  • the button 20a allows the user to set a tag to implement features to be described hereinafter.
  • the system shown in Figure 1 is only an example of one embodiment and should not be considered as limiting the invention in any way.
  • a graphical user interface such as the one shown at 22 in Figure 2 may be displayed in response to actuation of the button 20a in the course of receiving a video transmission.

  • the user could operate the button 20a and in response the graphical user interface 22 may be displayed.
  • the interface 22 may overlay over the existing display and may be a relatively small box or window which does not unduly restrict the viewing of the ongoing transmission.
  • the user may be asked whether the user desires additional information about a given brand of product ("brand X") or about detergents in general. By pressing either of the "yes" buttons, the user can select additional information which will be downloaded to the user. Otherwise, the user can operate the return field by tabbing, using the arrow keys 18 and the selection key 19 as described previously.
  • the illustrated graphical user interfaces are by way of example only and should not be considered as limiting the invention in any way.
  • the user in response to the user interface 22, the user may indicate that yes, the user wants more information about the particular brand being displayed and yes, the user wants more information about the product in general.
  • tags are set to control the subsequent collection of information for the user.
  • the software for correlating user selected information with information that may be provided at a later time through another channel is shown in Figure 3 and is called "video tag" software 21.
  • a tag is identified in the on-going video transmission as indicated in block 23.
  • a tag is identified when the user selects a given segment or portion of a video transmission as one about which the user would like to receive additional information.
  • the tag system may be implemented, for example, using script synchronously transmitted with the video.
  • a check for user selection of the tagged information is then undertaken, as indicated in block 25.
  • the tag information is stored (block 27).
  • a second video transmission is then scanned for information associated with the tag as indicated in block 29. This scanning may occur at a later time when the information eventually is provided over a different channel. The user may then be notified of the acquisition of the requested information. In this way, the user can receive additional information despite bandwidth limitations. Even though the information may be provided at a later time, the system allows the user's request to be correlated to the subsequent transmission.
  • the software for implementing the tag system begins by checking whether a tag input has occurred, as indicated in diamond 26.
  • the tag input may be initiated by the user operating the button 20a and selecting the "yes" option in connection with a graphical user interface, such as the interface 22 shown in Figure 2.
  • the software determines the appropriate identifiers for the ongoing video transmission and stores those identifiers.
  • the associated identifiers indicate what information was being displayed and what the user selected for further information.
  • These identifiers could be obtained, for example, from information simultaneously transmitted with the television program. For example, that information might be contained within the vertical blanking interval.
  • the software 21 may initiate a scan of another channel which provides additional information associated with information on one or more other channels, as indicated in block 30. If the identifier which was stored, matches an identifier associated with information being downloaded on the other channel, as indicated in diamond 32, a prompt may be displayed as indicated in block 34. A match indicates that in fact, the information has now been received which matches the identifiers associated with the information the user desired. When a match is detected, a screen display or graphical user interface 44 may be provided, as indicated in Figure 5. Again, the information may be provided as an overlay which does not unduly obstruct the viewing of the ongoing video transmission. Thus, the user is notified that the information is available and may be selected, for example, by tabbing to the block 45 and pressing the enter key 19.
  • information from the other channel is stored as indicated in block 36.
  • the user can view the stored information whenever the user desires. If there is no match, the software continues to monitor the other channel until a given time period has expired, as indicated in diamond 38. Once the time period has expired, the identifier (stored in block 28) may be deleted (block 40) and a screen display may be provided as indicated in block 42. This screen display may advise the user that the requested information was not received within a predetermined time period and therefore, the user will not receive that information.
  • the user can select information which the user desires and that information may be correlated with information which is being asynchronously downloaded on another channel.
  • This provides additional bandwidth for receiving the related information.
  • it provides a way to tie the user's desired information to information which is asynchronously transmitted on another channel.
  • the identifier system may be used to determine what information the user desires.
  • the software 21 may find the associated information and notify the user when it is received.
  • the additional information may be received some time after the user makes the initial selection that he or she desires the information. Then when the user is ready to view it, the information is accessed for viewing on the user's system.
  • channel one may correspond to the channel that contains program information such as a television program which the user views.
  • program information such as a television program which the user views.
  • a plurality of tags X, Y, Z, A, B, C and D may be associated with segments 50 through 62 of the video transmission. These segments could correspond to portions of the television program or one or more advertisements which may be provided in the course of a television program.
  • the identifier X is stored.
  • the identifier X may correlate with information on a second channel, channel two, providing a video transmission 48 in Figure 6 having segments 64 through 72.
  • the information corresponding to the identifier X may occur within a segment 70 in channel two which is displaced in time with respect to the segment 50 that is associated with the identifier X in channel one. This is no problem since the identifier X allows the information to be correlated, obtained at a later time and stored.
  • channel two may contain information in time periods 64, 66 and 68 that are associated with identifiers E, F, and G which may have no relationship to information on channel one.
  • the software may locate the identifier X in the time period 70 and the identifier Y in the time period 72 which are associated with television segments 50 and 52 on channel one. If the user selected the appropriate tags X or Y in the course of viewing channel one, the information in channel two associated with the segment 70 and 72 may be identified and stored for viewing by the user.
