TW380353B - Video tape and apparatus for playing such a video tape - Google Patents

Abstract

A pre-recorded VHS video tape has teletext data multiplexed with the video signal. The teletext data is encoded into a multilevel, for example four level, code at a reduced data rate so that it falls within the bandwidth of a VHS recorder. The recorder includes a decoding circuit which takes the multilevel code and converts it to binary data. The binary data is then encoded into standard teletext packets for acquisition by a standard teletext decoder in TV set. The teletext data is updated as the tape is played so that a given teletext page contains different data at different points along the tape. A number of creative programme applications are disclosed.

Description

5. Description of the invention (1) A VHS video tape and the invention for playing the video tape are related to a device. Part 5:: Shen: Addicted people and others have also submitted in the UK and are still under review <

3 =: National Patent Application No. 96_4. 8 (PHB). Knows a way to record a message on a VHS video tape. "J Replay the data when the video tape is played. As everyone knows: and; And in a non-distortion way = the transmission of electricity is known and the reason for the two is the frequency bandwidth of the standard VHS video recorder; and: the data rate of the electrical and information signals is too high to be properly handled. See information :: ί ί The system described in the application is a multi-level lightning code that uses the teletext format to produce samples that are less expensive than the standard teletext data rate. , On the videotape. In a special example, the multi-level raven tons of material pulses: 欠 'and the two telegrams received, the message: ah, combined after receiving If one of the data of this multi-level code is transmitted by J, ☆, it can effectively halve its asset rate, and then it can be processed within the bandwidth of a _a type VHS video recorder. Videotape of a TV receiver with a built-in teletext playback device that displays a teletext information page The rewarder provides a new service. ^ ^ The VHS booklet #, & > of the present invention has undergone multiplexing, and its recording ^ 'its uploading has been the same as a video signal, ... Teletext data, the teletext data has been changed to a multi-level code, the data rate is lower than the data rate of the general standard broadcast book No. ^ ^, and recorded in the general standard VHS Within the machine's' the telex data and the information on the videotape and a

D: \ Y87 \ 54649.ptd Page 5 V. Description of the Invention (2) ’and accept the update of the relevant information of the Assets Section on the Teletext page within the scope of the entire video. Using the traditional telex transmitted by a broadcaster-the same signal repeatedly transmitted in a cycle. It is included approximately after and the propagation cycle is repeated once. At the next change of ^ ten seconds, the material page may have different versions (in a cycle of repeated funding, after a certain period of fuel, all the different versions of these data pages are content = pass-complete, and the poor material also It was repeatedly transmitted. News items and announcements may be updated in a periodic manner in the Ma ring broadcast, but it is static data for 5 days, and it is the same as the content of the TV program that transmitted the above telex message. It has nothing to do with it. &Quot; The average person on Xinbo Road acknowledges that the content is pre-recorded on a video tape, which is known to the person who provided the video. Publicly, this approach may provide a Space, cooperating with this telex, telex and video data. In this way, media producers can benefit = poor species. A new way to design the structure of this telex text database is to make such information a shadow Dynamic changes during the playback of the tape. 5. Media producers can use standard teletext equipment to design the structure of the teletext database. But the difference is that the original teletext page was designed and designed. The device is connected to the video replay host. The time f code sent by the main video signal source can be used to start the insertion of different teletext pages under the control of the editor. In this way, the contents of the available video tape can be recorded Change the content of the teletext database during the process. When the video viewer selects a specific teletext page to replay the video, the data content can be replayed according to the video at that time. Page 6 D: \ Y87 \ 54649. Ptd 5. The description of the invention (3) changes in conjunction with this. This method can provide a variety of groundbreaking possible operation methods. One example is a different traditional video tape containing a detective story movie drama program Some of the traditional telex information materials recorded in the content of this videotape. The data base is a single index page or a few pages of information. Information on various telex information service items provided. These service items The information for each of these services is usually allocated on one page or a group of information pages. One or more of these single or group data pages may become the information page of "The plot ends here." Start to play When it comes to videotape, there is very little information about the plot first. And there will not be a lot of information on this first page. When the time continues and the important plot of the movie story continues to appear, the content of the information These episodes will be explained (depicted) and added to the "End of Plot" info page above. At the end of the video, the single or multi-page "End of Plot" page will be included in the movie story Summary information of all the important episodes that happened. Therefore, when the video viewer replays the video to a certain intermediate point, if he wants to interrupt the viewing and may return to the point to watch again after a few days of interruption, he can call out The "Story ends here" information page quickly glances over and recalls the plots that have been seen before. In this way, if the video is paused and stopped, the viewer does not need to rewind the tape to the video At the beginning, recall the plot that he has seen before; on the contrary, the viewer can start playing the video tape from the place where the viewing was interrupted, and call the "end of the plot" News page, so watch recalls the story seen before, and have to continue to watch the rest of the story of the film. The second example presented here (this method may be a video recording of a detective story

D: \ Y87 \ 54649.ptd Page 7 V. Description of the Invention (4) The belt is particularly suitable) is to observe the effect with different ^ different ^ == Yin. In the plugging, the story of the character asked in the battle drama will be updated at any time, and will be updated at any time. : Can provide some detective stories that will use some of the wrong clues, traditionally unknown to a certain extent. * Yes, the wrong explanation to increase the confusion of the plot The third example presented here is the feasibility of the technique to improve the above effect. Note that similar to the news (brief) newsletter, you can learn 'if you do n’t want to replace the information: depending on the technology of the program, you can display the information in the full-page telex video information in the way of the news page. Make the call; j = The information is added to the middle one, Nie Lu- «, and the content of the message is transmitted on the TV screen page, and only the text is superimposed on the day and time. Show in Satan. If necessary, the size, shape, and position of the overlay information column can be changed automatically according to the size of the video data. There are many examples of this innovative use of technology, including circular illustrations of cartoon-like speech content appearing on the television screen with characters at the same time, or selectively covering an important part of the television daytime with an information column, such as' a Contains an information column describing prosecutor Le Plodd ',, s's confidentiality claims regarding the murder weapon information. The other is to remind the viewers of the video to watch the painting. Page 8 D: \ Y87 \ 54649.ptd The following is written in the video: "Mechanical and descriptive of the video problem and the post." After the above, a different kind of real but will be presented on all the video tapes, that is, the video tape data can be replaced by a full page of video information and mixed into a way to display without video information. In another way, Inside the frame of visual materials, or like short news sentences. Four rewards and puzzles each one reward test-one kind of Zen one answer any time, the J Zhi stomach group comprehensive database feels like »Π, .., say, time is not a special object or character; it is time to see who is hiding behind the tree” and other dynamic ways to change the teletext article ’s entertaining materials—a special case , And then submit the data or multiple-choice answers related to the video material. Videotape k Select a specific page number or press the color key method used to select the correct answer to the question. Or it may show that you may need to answer the time limit and fail to propose some answers, such as "Time has exceeded the index. Soon, it will produce-a real father-talking feeling. Of course, you can watch people. Both are recorded in the change of the recording maneuver. In this regard, but the time shown here and the time elapsed after the start of playback at a specific time on that day may be examples of information displayed on the screen. Teaching. Some video materials are teletext pages, asking similar questions based on similar topics in cases such as Fast X t or T 〇 P. Other information will be determined in a limited time page. But if the super answer page changes the sentence and some sexual questions and answers appear at the same time, it ca n’t really talk, because those questions are treated as information as time goes by. Match, but equal to the message 'or may need to transmit data and video

V. Description of Invention (6) Like the mixed node, in addition to overlapping data, you can also use diagrams in a dynamic way, such as displaying a certain day and day in a gradual manner. When you perform a test question, you can add the 5 Before some parts of the character rewarder can get who is in this quiz, it must be shown that another example is a product catalog using this technology. Therefore, it may be necessary to display pictures and also use telex to communicate other information, such as: prices, local vendors. Other related information. However, it is not necessary to broadcast continuously throughout the video playback. During or immediately after the video appears, the library is taken out and displayed on the screen. The same part contains different telex texts. The method disclosed in the present invention has several detailed descriptions of hundreds of (teletext) related matters. At the same time, it is not occupied by the description of the entry at a fixed point in time (or time period). Therefore, it can also be used on the same videotape than the general broadcast telex message transmission. Select the part of the video material that you want to use. Gradually, you will use the product to show more products. Selective sellers will add these, because the above article is such an information source. This leaflet is available on the telex video in multiple languages. In addition to create special effects screen information. The problem is to clearly show that the sub-end regards this view as a small part of the picture brought by the recording video, and shows that the product specifications, telex information, and other information need to be self-ranking. Enables recording. One method is to fill in the video database of the newsletter. He recorded the access of Gongxun in part and the time of language access. In this way, that is, the content of the text, for example, therefore, the person watching the video is guessing the criteria. Make a copy and display the product and any material pages in the product. It ’s natural. The self-financed% has insufficient space to provide each phase with one other thing. The operation time is faster. Each of these functions can

V. Description of the invention (7) The information pages are reserved for English materials only. One of the suppliers wishes to keep them exclusively for the group on the video-the poor material pages can be used in any other language materials. Install French 'German or its examples and specific drawings of the present invention as described below, when the above and other features of the present invention can be understood = f each item of the description la and lb show-standard broadcast electricity; point J : The number of the limited band width of the VHS recorder, and-Figure 2 shows-a kind of representative of the above-mentioned broadcast; the code 'is available for VHS recorder to record and replay; The time scale of the signal shown in Figure 2 is relaxed; after the time scale is relaxed, Figure 4 is a map of the recording equipment purchased by the media producer in accordance with the requirements of this video. The block diagram of the required video playback device is shown in Figure 6. The example is in accordance with the principles of the present invention. * Related telex data pages; there are self-recording. ; Figure 8 shows a newsletter-style display using video in accordance with the principles of the present invention; The example shown by Pearson, 9a and 9b shows how a pre-recorded video 3 can be used for entertainment Or educational quiz show. Figure h shows a standard teletext signal received by a receiver. The data rate of the teletext signal is greater than 5 MHz, so ’

When fed by a video recorder (such as a standard VHS video recorder with a channel bandwidth of about 3 MHz), the signal will be distorted . Figure lb shows how the teletext signal is affected by the channel bandwidth of a standard VHS recorder. As can be seen from the figure, the insertion information of the original timepiece in the original signal has disappeared. Therefore, during replay, a standard teletext decoder cannot decode the insertion information signal. In order to overcome this problem, in the British patent application No. 960561 4.8 (PHB 340 56) filed by the company at the same time-a method, the main use of a multi-level code, the data rate of low-type telex information rate. The figure shown in Figure 2 is a series of transmitted message data decoded from a four-amplitude-level code. The original timepiece insertion signal has been replaced by a lower frequency time 'insertion signal, while the information segment code and data are replaced by the four-tone 3 thunder and 37. The four levels in this example are the four amplitude levels; $ 7 yards can decode two bits during each breeding period. The electricity / horse supply is 00, 〇1, 10, and U. . Therefore, the above telex :: The data rate of the decoded code of the second-tier level is equal to the standard s D number, and the data rate is-half (1/2). Therefore, it has fallen into the VHS recording 2 = Xinwei within. 3f width range Figure 3 shows a telegram processed with multi-layered code. Therefore, the initial part of the patent application disclosed in the above cited patent signal, the time scale of the signal has been expanded. Wide, can be 5 _ signal column segment code and time running period in the data. In this example: after the frequency of the signal is set, it is equal to one-half (1/2) of the standard telegraph message timepiece and j timepiece insertion. Incoming signal frequency

For a specific example, quasi teletext shima, its — (1/3), for the single bit code, because of the multiple levels of data recovery. "Fu," Township's teletext data conversion & _kinds: # Multi-level code whose data rate is lower than the data rate. Then the multi-level h is centered so that the data can be recorded in the code 2 plus. It uses a four-level amplitude code, which is one and a half (1/2) of the data rate of the signal. If eight layers are used, the standard data rate may be reduced to 38% of the standard teletext data rate. Λ is the secondary data rate. Allowable decoding in the | -data period "70. Although it is best to use a multi-amplitude layer This kind of electric horse can simplify the operation of ^ 5 processing, and the telegram decoder performs the telegram. In addition, Ertianda can also use a mixed multi-level electric broadcast including multiple different phases 3 ~ phase and amplitude. When reading from a tape, the data rate is converted into a layer-level code, and then the read-out code is transmitted to the message decoder by the reverse operation method, which is exactly the same as the conversion of the video to the standard telex data. The value is 2. Afterwards, this information can be sent to a power station and transmitted to the relevant video. The video signal can be recombined to record and replay the video streamer. This way, you can use the United Kingdom proposed during a VHS recording. The entire process of the exclusive $ = ^ materials has been published in the above-mentioned content of the same application of the company, and has been published in this application.

Description of the invention (10) (recaptured or rebroadcasted), also refers to any resources that can be carried (or carried) within the VBI of a television signal and related to television programs. These materials include MHEG_5 (MHEG stands for Multimedia Hypertext Experts Group), and Hypertext Mark Up Language. The binary data rate of each type of data is It is too high to be recorded or replayed by standard video recorders. Although the above description with reference to Figures 1 to 3 has discussed the collection of teletext signals and the subsequent replay technology, it should be clear that the teletext information that has been encoded in accordance with this procedure can also be pre-processed. The information contained in the videotape can be replayed by the purchaser or renter of the videotape. The media producer shown in FIG. 4 needs video recording equipment to make a video tape in accordance with the principles of the present invention. The video source 丨 (such as a video camera ′ ^ present% program television broadcasting equipment, etc.) feeds the video signal to the main video editing device 2. The main video signal editing device 2 should be provided with a video controller 3 and a video monitor 4 to enable the video producer to send video data from the edge-source data source and also observe the edited video data. Youshi ”Wenxun Founding System 5 'Yes—or multiple editing terminals 6 for receiving the code sent by f video editing equipment via line 7. The teletext stand is 8 °.

The information page text may be: "Prosecutor ^, PlcHid received a strange phone call from Miss Jinx ', which does not have a lot of substantive content. It is only a hint that there are rumors that the village of Dorset is evil. event". Figure 6b shows the same telex information page, which was called by the video viewer when the video was replayed to midway. It can be seen from the icon that the information page of the "Story" so far contains more information than before. For example, the information may be: "Someone found that Colonel BlunderbUSs was shot in the library of Doom Manor in Dor set. This It may be a suicide case, but prosecutor Le P10 odd tends to think it is a murder. Many people have reason to think that Colonel B1 underbuss would be fine if it wasn't the dangerous ringing order of the time. Maybe The suspect is ... ". Therefore, we know that the video tape is still playing. The information on the "End of Story" profile page can be updated at any time. If the viewer interrupts the viewing for some reason during the video playback, even if the interrupted viewing period lasts for several days or even weeks, the viewer resumes viewing

V. Description of the invention (14)-At this time, it is not necessary to rewind the video tape to the beginning to recall the plot that occurred before the interruption of the viewing, and then continue to watch the subsequent plot from the original interruption. Figure 7 shows the different telex information pages, providing observations of different characters in the film on things. Figure 7a shows the general opinion of Prosecutor Le P10 dd, while Figure 7b shows the general opinion of Miss Jinnx. The text in Figure 7a might be: "I don't know what's going on, that innocent good girl was normal. There was no doubt it was born out of nothing. She must have read too many detective novels. Better The question is about Doom Manor, and the people there are really weird! "Figure 7b shows what Ms Ji Jin X said. She might say," Why are these police officers so stupid? What about him?
