The user can be provided with mark by control button 20a in the process of receiver, video transmission.At the beginning, for the response in the receiver, video transmission course to the startup of button 20a, can show one as the graphic user interface shown in 22 among Fig. 2.For example, in playing the commercial break process of washing agent, the user 20a that can touch the button may be to demonstrate graphic user interface 22 to this response.Interface 22 can overlap on the existing display surface, can be less framework or window, not to watching ongoing transmission that undue influence is arranged.
The user can be asked user whether wish to understand about given brand product (" brand X ") or about the extraneous information of general washing agent.The user is by pressing a "Yes" button, and just can select will be to the extraneous information of user's download.Otherwise the user can be by switching (by tabbing) with directionkeys 18 and options button 19 by the label button as previously described, and the territory is returned in operation.Equally, just for example, should not be considered as is any limitation of the invention to shown graphic user interface.
So, in one embodiment, in the process of commercial break, the user can action button 20a, at user interface 22, the user can point out that the user is to want the more information of shown particular brand and is the more information of wanting about general product.When having operated each of these graphic user interfaces for the selection extraneous information, just be provided with mark, be used for being controlled to be subsequently user's acquisition of information.
Information that the user is selected and the software that can be associated in the information that later provides by one other channel are provided, in Fig. 3, show, be called " video marker " software 21.At the beginning, mark of sign in ongoing video transmission is as shown in square frame 23.When the user selects in the video transmission given section or part will receive the section of its extraneous information or part as the user, just identified a mark.Mk system for example can be with realizing with the script of audio video synchronization transmission.Check the selection of user then, as shown in square frame 25 to label information.
After the selection, label information is stored (square frame 27).In second video transmission, search for the information that is associated with this mark then, as shown in square frame 29.This search can later carried out when this information provides on different channels at last.Can notify the user to obtain institute's information requested then.Like this, although limited bandwidth, the user also can receive extra information.Even this information may later provide, system can make user's request carry out related with transmission subsequently.
Realize the software of Mk system, be shown in more detail among Fig. 4 this software checks the mark input whether occurred at the beginning, as shown in diamond 26.In the embodiment shown in, the mark input can be initiated by the user, and method is action button 20a, selects the "Yes" option on the graphic user interface (interface shown in Fig. 2).According to current just received video transmission, software is determined the respective identifier of ongoing video transmission and is stored these identifiers.Like this, the identifier that is associated points out showing originally that what information and user have selected and so on further information.These identifiers for example can be from obtaining the information transmitted with TV programme simultaneously.For example, this information may be included in the vertical blanking time interval.
When the user watched the video TV transmission of a particular channel, software 21 can begin to search for another channel that extraneous information that is associated with information on one or more other channels is provided, shown in square frame 30.As shown in diamond 32, if in the past the identifier of storage with conform to identifier that the information of just downloading on one other channel is associated, then can show a prompting, as shown in square frame 34.The identifier expression that conforms to, the information with conforming to identifier that the information of user expectation is associated is received now.When detecting when conforming to, can provide a screen display or a graphic user interface 44 as shown in Figure 5.Equally, this information can show overlappingly, hinders within bounds and watches ongoing video transmission.Like this, the user just obtains notice, and this information is available, can be for example by the switch labels button to square frame 45 and press enter key 19 and select.
Referring to Fig. 4, when conforming to, as shown in square frame 36, will get up once more from the information stores of one other channel.Whenever the user can both watch institute's canned data its hope.
If do not conform to, software continues the monitoring one other channel, and is overtime up to the time, as shown in the diamond 38.In case the time is overtime, just can as indication in the square frame 42, provide a screen display then with (in square frame 28, storing) identifier deletion (square frame 40).This screen display can be reminded the user, and institute's information requested is not received within the predetermined time, so the user will not receive this information.
System 10 has been arranged, and the user just can select its information of wanting, and this information and the information of downloading asynchronously on one other channel can be got in touch.This provides extra bandwidth for receiving relevant information.In addition, system also provides a kind of approach that user information of wanting and the information of downloading are asynchronously got in touch on one other channel.What in other words, can determine that the user wants with identifier system (identifier system) is any information.By using identical identifier system search information on second channel, software 21 can be sought the information that is associated and notify the user when receiving this information.Time when extraneous information is received, can be later than the user and make the time that he or she wants the initial selected of this information.Then, when the user is ready to watch this information, just can use this information, in user's system, watching.
So in Fig. 6, channel one can be corresponding to the channel of the programme information that contains the TV programme of watching such as the user.In the process of the video transmission 46 on channel one, a plurality of mark X, Y, Z, A, B, C and D can be associated with each section of 50-62 of video transmission.These sections can be corresponding to the one or more advertisements that provide in a plurality of parts of TV programme or the TV programme process.So, if during section 50 user's button click 20a, then identifier X just is stored.
Identifier X can with second channel be information on the channel two get in touch-video transmission 48 that channel two provides in Fig. 6 has 64 to 72 each sections.Particularly, in channel two corresponding to the information of identifier X may the section of appearing at 70 in, the section 50 that is associated with identifier X in the channel one relatively has skew in time.This is not a problem, because identifier X allows informational linkage is got up, is later obtaining and is storing.
So channel two can comprise the information in time period 64,66 and 68, they are associated with identifier E, F and G, may have no relation with the information in the channel one.Yet, identifier X in the time period 70 that software can be located with TV section 50 and 52 on the channel one is associated and the identifier Y in the time period 72.If the user selected corresponding mark X or Y in the process of watching channel one, just can determine the information that is associated with section 70 and 72 in the channel two, and store for the user and watch.
At the head end of the reflector shown in Fig. 8 108, can carry out asynchronous transmission to a plurality of receivers 110 with two channels 112 and 114.In other words, the information that is associated with same mark for example can be later than on one other channel on a channel and transmit, as the preamble explanation.Although only represented a reflector 108 among the figure, in one embodiment, reflector can comprise the discrete reflector of corresponding each channel.
