In an embodiment of the present invention, such as, receiving element 11 and display unit 12 arrange in a television set, then receiving element can from Set Top Box receiver, video and binary coding.Again such as, display unit 13 is arranged in the terminal equipments such as mobile phone, and scanning obtains the binary coding on television set.
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, the present invention is described in more detail.
By in the playing process of video content, utilize and whether have black frame to insert mark binary " 1 " and " 0 ", and then insert the non black frame of human eye in screen display process high speed, according to the extraneous information of the coding carrying needs displaying that black frame and normal frames are formed.User can use the instruments such as smart mobile phone to shoot with video-corder and resolve video-frequency playing content, identifies and decodes, and show the data message embodied in wherein black frame and normal frames sequence, and such as word-information display or hyperlink are accessed.
The insertion of black frame can have two kinds of modes.First, directly in the content flow of video, increase black frame, which needs to carry out larger amendment at video program source to its content, simultaneously because the play frame rate lower (usually at 30FPS) of video frequency program, is difficult to meet the requirement that black frame inserts the response time.Second, black frame is inserted in screen display process, embodiments of the invention adopt which, namely, program source is loaded in the Set Top Box of user side, be transmitted to the display device such as television set, display by Set Top Box, in video display process, the display device such as television set, display inserts black frame by showing at a high speed black frame or cutting out the modes such as backboard light source.
Black frame and normal frames are binary coding, that is, carry the extraneous information needing to show in video display process in binary mode.Coding rule adopts the expansion based on TLV coding, wherein: the beginning of T (Type, type) domain identifier beared information; L (Length, length) territory indicates the length of one section of coded message; V (Value, value) territory is used for the coding of beared information.According to coding schedule, the extraneous information carried by black plug is converted to binary coding by Word message.
In addition, considering in video display process and also may occur entirely black situation, therefore in order to avoid obscuring mutually with the extra black frame inserted, in each coding, needing the extraneous information repeating repeatedly (such as, n time) carried.In addition, check code can also be added in each coding, to verify coding.
Figure 2 shows that the schematic diagram of coding.As shown in Figure 2, coding refers to the binary code sequence of a string black frame and normal frames composition, and black frame represents binary one, and normal frames represents binary zero.Or also can represent binary zero by black frame, normal frames represents binary one.In coded sequence, two bit-identifies of the foremost type of this coding, such as " 00 " represents this information is Commdity advertisement, and type identification can be used as the initial judgment basis of an information coding string, does not have repetition with the coding of follow-up length information, value information; The middle four bit-identifies length of information, namely points out that how many follow-up binary digits carry effective information (containing check code); Last binary string contains the value of information and check code, the value of information by information coding (such as 0001 can for letter " a " coding) repeatedly occur work out, what this can be avoided the black frame of normal play to cause obscures, check code can have various ways to select, the most simply parity check, such as, in encoding, the occurrence number of binary one is the words check digit of even number is the detection that " 0 " lost efficacy to tackle single binary digit.
It will be understood by those skilled in the art that an above-mentioned just signal of simply encoding, concrete coding rule can set according to the information delivery request of reality, such as value information frequency of occurrence, check code set-up mode etc.
So-called screen black plug, refer in video display process, insert the non black frame of human eye at a high speed, black frame and normal frames is utilized to represent respectively " 1 " and " 0 " of binary code, and then form binary coding by inserting spacing difference, need the information of being shown by Quick Response Code in carrying traditional approach.
By screen black plug beared information code, the theoretical foundation not affecting again viewer experience comprises two aspects: first is because human eye has persistence of vision mechanism, therefore, when video playback frame per second is more than or equal to 24FPS (FramesPerSecond), spectators will feel smooth; Second is there are some researches show if in screen display process, and the black frame insertion response time can be less than 8ms, and human eye would not be perceiveed to some extent to it.For these reasons, can avoid having an impact to the vision of spectators.
When user watches TV programme, the content that video playback on screen shot with video-corder by terminal equipment (such as mobile phone etc.) can be passed through.In this course, all displaying information on screen (comprising the appreciable normal frames of spectators and the non black frame of spectators) all will be recorded one by one.Terminal equipment (such as, be built in the mobile phone application software that in mobile phone one is special) identify normal frames and black frame, such as find that the screen picture that displaying contents is entirely black is black frame by pixel analysis, if not being entirely black, regard as normal frames, black frame and normal frames are combined together to form complete binary coding.Then, resolve this binary coding according to coding schedule, obtain the Word message (such as text message, hyperlink) wherein contained.Finally, the terminal equipments such as mobile phone can be shown these Word messages, such as, directly show text message or open hyperlink by browser.
Figure 3 shows that a kind of structural representation of embodiment of system for displaying video information.Towards typical scene be spectators by Set Top Box received television program and watch video content on a television set, utilize the terminal equipments such as mobile phone to shoot with video-corder display information on television screen.Effectively can be supported in video display process the carrying of extraneous information and to represent.This system embodiment can comprise: Set Top Box, television set and terminal equipment.
At video frequency program source, will the extraneous information represented in program is play be needed to be encoded to binary form, and and then joined EPG corresponding to program (electronic program list) system by the metadata information as program.Here the particular content changing video frequency program is not needed.
After spectators turn on Set Top Box and television set and have selected the program of wishing viewing, first this request will be sent to EPG system, the metadata information (comprising the binary coding that screen represents extraneous information) that this program is relevant can be delivered to viewer side by EPG system, and and then provides follow-up video data information.
The binary coding of the extraneous information that program metadata information comprises is sent to television set by Set Top Box.Television set needs to insert black frame in follow-up program playing process high speed according to coding, realizes the loading be coded in video display process.Such as, coded message is 0101, and normal frames represents " 0 ", and black frame represents " 1 ", then after first normal frames, insert black frame, inserts a black frame after second normal frames again.
Spectators shoot with video-corder video screen information by mobile terminals such as mobile phones, then and by special application software video requency frame data is resolved, know the binary coding be made up of black frame and normal frames, and then these binary codings will become Word message by code conversion, and show on mobile phone (such as word-information display or hyperlink are accessed).
In this embodiment, if calculate (namely video playback frame per second is 24FPS, does not have black frame to insert) according to minimum transmission code check 24bit/s simultaneously, at least can transmit 90 byte datas in 30 seconds, there is enough transinformation content.Between normal frames, insert black frame, can transinformation content be increased, and do not affect the normal play of normal frames.Therefore, current screen display Quick Response Code mode can be substituted to embed the extraneous information on video screen.
