Definitions

  • the invention relates to a method and apparatus for the transmission, recording and reproduction of video signals, and to an information carrier for video signals, additional signals being able to be used during the reproduction of the video signals in order to enable an application of forces to the human body or a feel for contents of the video signals displayed.
  • the invention is based on the object of specifying a method for the transmission or recording of video signals which enhances the experience when viewing films at home. This object is achieved by means of the method specified in Claim 1. Furthermore, the invention is based on the object of specifying a corresponding method for the reproduction of the video signals and an apparatus for carrying out the aforementioned methods according to the invention. This object is achieved by means of the method specified in Claim 5 and the apparatus specified in Claim 9. Finally, the invention is based on the object of specifying an information carrier for such video signals. This object is achieved by means of the information carrier specified in Claim 10.
  • the invention is based on the insight that in the domestic sector, too, the experience of viewing a film can be enhanced by a physical perception being enabled in addition to a perception of picture and sound.
  • the invention' s method for the transmission or recording of video signals therefore consists in the video signals and additional signals which can be used during the reproduction of the video signals in order to act physically on the human body or to enable a feel for contents of the video signals displayed being transmitted and/or recorded jointly as a television signal.
  • the additional signals are in this case preferably inserted into the vertical blanking interval of the television signal. This ensures backwards-compatible transmission since, on the one hand, the additional signals can be separated from the video signal and processed further in a straightforward manner at the receiving end but, on the other hand, the video signal itself is not interfered with and, therefore, the video signals can also be reproduced without interference on conventional receivers.
  • the additional signals are transmitted as teletext signals. This makes it possible for the separation of the additional signals from the video signals to be carried out by the teletext decoder which is present in any case in the television set.
  • the additional signals are suitably identified, so that reproduction can be effected by correspondingly equipped receiving or reproduction devices and, on the other hand, the additional signals are not taken into consideration in a conventional receiving or reproduction device, backwards compatibility thereby being ensured.
  • the invention's method for the reproduction of video signals consists in a television signal being examined for an identifier for additional signals which are used in order to act physically on the human body or to enable a feel for contents of the video signals displayed, and, if the identifier is present, the additional signals being separated from the television signal and being output together with the video signals.

  • WSS bits are communicated, which contain an item of information about the format of the video signal displayed.
  • teletext is utilized in order to reproduce, in addition to the television programmes offered, current news, weather reports, sports information, etc., by means of characters and graphics on the screen.
  • the teletext signal can also be utilized in order to enable, instead of a transmission of message information, a transmission of additional signals for physical feedback, also called force feedback signals hereinafter.
  • the additional signal 12 is firstly fed together with telext signals 15 that may be present to a unit 13, in which both signals are converted into the teletext format and combined.
  • telext signals 15 that may be present to a unit 13, in which both signals are converted into the teletext format and combined.
  • the combined signal 14 is then fed together with the actual video signal 11 to a multiplexer unit 16.
  • This multiplexer 16 then inserts the additional signals and teletext signals into the VBI of the video signal 11.
  • This combined signal 17 is then transmitted and, at the receiving end, fed to a corresponding demultiplexer 18.
  • the latter then separates the signal 14, which comprises the additional signals and teletext signals, from the video signal 11.
  • the teletext and the additional signals are then separated from one another in a recovery unit 19 so that they can then be fed to suitable reproduction units.
  • the data are encoded hierarchically in six layers, which are designated as sequence layer, GOP (Group of Picture) layer, picture layer, slice layer, macroblock layer and block layer. These different layers allow access and separate treatment of different basic elements of the data stream generated.

  • the specification provides data areas, called user_data hereinafter, which can be utilized by the user for specific applications.
  • the use of such user_data for the transmission of force feedback signals in digital television is illustrated in Figure 2.
  • Force feedback signals 21 are fed to a force feedback encoder 23, which inserts the force feedback signals into the user_data.
  • the encoded force feedback signals 26 are then fed to a multiplexer 28.
  • the video signal 22 is fed to a video MPEG encoder 24, which, for the encoding, is connected to a buffer memory 25.
  • the MPEG-coded stream is then likewise fed to the multiplexer 28.
  • the force feedback signals are then inserted into the user_data of the picture layer of the MPEG video bit stream.
  • the encoding of the audio signal which is likewise fed to the multiplexer 28, is not illustrated.
  • the combined signal is then transmitted or recorded in this way on an information carrier such as a DVD. During reproduction, the inversed steps are then effected.
  • the signal is fed to a demultiplexer 29. The latter firstly separates the force feedback signal in the user_data of the picture layer from the video bit stream.
  • the force feedback signals 26 are then fed to a decoder 210, which regenerates the original force feedback signals 21 from the signals transmitted in the user_data.
  • the video signal 27 is fed to an MPEG decoder 211, which in turn decodes the video signals using a buffer memory 212.
  • the video and audio and force feedback signals are then fed to corresponding reproduction apparatuses.
  • any desired apparatuses for exerting forces on the human body For the reproduction of the force feedback signals, it is possible to make use of any desired apparatuses for exerting forces on the human body: Thus, it is possible to provide suitable chairs which can be tilted in different directions by electric motors. Likewise, it is possible to provide ata gloves", which make it possible to feel film objects displayed. Finally, any desired body sensors can be stimulated in a controlled manner, not just those which detect force. Thus, it is also possible to make an impression on the sense of temperature, taste or balance. This can also be done without direct contact with the respective sense organ, e.g. by using electric or magnetic fields.
  • the invention can be used in a wide variety of devices appertaining to consumer electronics, such as e.g. of TV sets, set-top boxes, video recorders, DVD players, satellite receivers, TV-video combinations.

Abstract

L"expérience associée au visionnement de films à domicile est améliorée par une perception physique qui s"ajoute à la réception de l"image et du son. A cet effet, des signaux vidéo et des signaux supplémentaires qui peuvent être utilisés pendant la reproduction des signaux vidéo afin d"agir physiquement sur le corps humain ou de permettre une sensation associée au contenu des signaux vidéo affichés sont transmis et/ou enregistrés ensemble en tant qu"un seul signal de télévision. Dans le cas d"un signal de télévision analogique, les signaux supplémentaires sont introduits dans l"intervalle vidéo vertical du signal de télévision, avantageusement en tant que signaux télétext. Si le signal de télévision est transmis ou enregistré numériquement, en particulier selon une norme MPEG, les signaux supplémentaires sont introduits dans ce qui est appelé les données_d"utilisateur des entensions_et_données_d"utilisateur de la couche d"images.
