Aufzeichnungsvorrichtung und -verfahrenRecording device and method

Die vorliegende Erfindung betrifft einen Datenträger, auf dem Audio- und/oder Videodaten gespeichert sind sowie eine Vorrichtung und ein Verfahren, mit denen die Audio- und/oder Videodaten auf dem Datenträger aufgezeichnet werden können.The present invention relates to a data carrier on which audio and / or video data are stored, and to a device and a method with which the audio and / or video data can be recorded on the data carrier.

Bisher ist bekannt, Audio- bzw. Videodaten auf einer sogenannten Compact Disc (CD) zu speichern. Für die Audiodaten wird dabei das von Sony und Philips 1983 entwickelte digitale Audioformat verwendet. Das Format zur Aufzeichnung von Videosignalen auf sogenannten Video-CDs basiert auf dem gleichen digitalen Audioformat. Eine CD bzw. ein CD-ROM besitzt eine Speicherkapazität von etwa 680 MByte, was einer Videospielzeit von etwa 70 Mi- nuten entspricht. Um nun einen Videofilm der üblichen Spielfilmlänge aufzeichnen zu können, wurde die sogenannte Digitale Video Disc (DVD) von mehreren namhaften Elektronikkonzernen in Zusammenarbeit 1995 entwickelt. Die Speicherkapazität einer DVD beträgt 4,7 bzw. 8,5 GByte, so dass eine Videospielzeit von 2 Stunden 13 Minuten gewährleistet ist. Die Audio- und Videodaten auf der DVD sind gemäß dem gemeinsam entwickelten DVD-Stan- dard formatiert.So far, it is known to store audio or video data on a so-called compact disc (CD). The digital audio format developed by Sony and Philips in 1983 is used for the audio data. The format for recording video signals on so-called video CDs is based on the same digital audio format. A CD or CD-ROM has a storage capacity of approximately 680 Mbytes, which corresponds to a video game time of approximately 70 minutes. In order to be able to record a video film of the usual feature length, the so-called digital video disc (DVD) was developed in 1995 by several well-known electronics companies. The storage capacity of a DVD is 4.7 or 8.5 GB, so that a video game time of 2 hours 13 minutes is guaranteed. The audio and video data on the DVD are formatted in accordance with the jointly developed DVD standard.

Von Sony wurde außerdem das PSX-Format für die Aufzeichnung von Videosequenzen einschließlich Audiodaten entwickelt. Dieses Datenformat findet insbesondere bei der Verwendung von „Playstations" von Sony Anwendung. Es sind also nur spezielle PSX-Datenträger zum Abspielen von Audio- und Videodaten auf einer Playstation geeignet.Sony also developed the PSX format for recording video sequences, including audio data. This data format is used in particular when using "Playstations" from Sony. Only special PSX data carriers are therefore suitable for playing audio and video data on a Playstation.

Insbesondere im Zusammenhang mit Musikstücken besteht nun der Bedarf die dazugehörigen Videos der entsprechenden Künstler beim Abspielen des Musikstücks mitbetrachten zu können. Ausgehend von Singleauskopplungen von Schallplatten wurde die sog. Maxi-CD ent- wickelt. Sie enthält das titelgebende Musikstück und gegebenenfalls weitere Musikstücke im Audioformat. Darauf basierend sind heute Maxi-CDs erhältlich, die neben dem titelgebenden Musikstück auch das dazugehörige Video des Künstlers enthalten. Diese Maxi-CDs ein- schließlich Videodaten sind mit einem Computer und dem dazugehörigen Standardprogramm (Real Time Movie Player) abspielbar.Particularly in connection with pieces of music, there is now a need to be able to watch the associated videos of the corresponding artists when playing the piece of music. The so-called Maxi-CD was developed based on single releases of records. It contains the title-giving piece of music and, if necessary, further pieces of music in audio format. Based on this, Maxi-CDs are available today, which contain the title of the piece of music as well as the associated video of the artist. These maxi CDs Finally, video data can be played back using a computer and the associated standard program (Real Time Movie Player).

Der Benutzer steht nun vor der Situation, dass die Maxi-CD mit Videodaten zwar auf einen CD-Player anhörbar, die Videodaten aber nur mit einem Computer und dem dazugehörigen Spezialprogramm bzw. einem DVD-Player oder Video-CD-Player zugänglich sind. Hinzu kommt dass zum Abspielen einer derartigen Video-CD bzw. einer DVD mit dem Computer ein entsprechendes Laufwerk und die dazugehörige Software benötigt werden, um die Videosequenz in Echtzeit wiederzugeben. Für den Fall, dass der Videoclip mit den Audiodaten im DVD-Format aufgenommen ist, besteht das weitere Problem, dass die Daten außer von einem Computer lediglich von einem DVD-Player lesbar sind. Ein DVD-Player kann in der Regel zwar Video-CDs abspielen, aber ein Video-Player ist regelmäßig nicht in der Lage auf DVD- Daten zuzugreifen.The user now faces the situation that the Maxi-CD with video data can be listened to on a CD player, but the video data can only be accessed with a computer and the associated special program or a DVD player or video CD player. In addition, a corresponding drive and the associated software are required to play back such a video CD or DVD with the computer in order to reproduce the video sequence in real time. In the event that the video clip with the audio data is recorded in DVD format, there is the further problem that the data can only be read by a DVD player, apart from a computer. A DVD player can usually play video CDs, but a video player is generally unable to access DVD data.

Angesicht dessen ergab sich die Aufgabe, die auf einem Datenträger gespeicherten Audio- und Videodaten durch mehrere Geräte zugänglich zu machen.In view of this, the task arose of making the audio and video data stored on a data carrier accessible by several devices.

Gemäß der vorliegenden Erfindung wird diese Aufgabe durch einen Datenträger gelöst, auf dem Audio- und Videodaten in mindestens zwei gerätespezifisch verschiedenen Formaten auf dem Datenträger gespeichert sind, so dass die Daten auf dem Datenträger für mindestens zwei verschiedene Abspielgeräte lesbar sind.According to the present invention, this object is achieved by a data carrier on which audio and video data in at least two device-specific different formats are stored on the data carrier, so that the data on the data carrier can be read by at least two different playback devices.

Erfmdungsgemäß wird hierzu ein Verfahren zum Speichern von Audio- und Videodaten auf einem Datenträger vorgeschlagen, bei dem Audio- und Videodaten jeweils in mindestens zwei gerätespezifisch verschiedenen Formaten auf dem Datenträger gespeichert werden, so dass die Daten auf dem Datenträger für mindestens zwei verschiedene Abspielgeräte lesbar sind.According to the invention, a method for storing audio and video data on a data carrier is proposed for this purpose, in which audio and video data are stored on the data carrier in at least two different device-specific formats, so that the data on the data carrier can be read by at least two different playback devices .

Ferner wird erfindungsgemäß eine Vorrichtung zum Speicher von Audio- und Videodaten auf einem Datenträger vorgeschlagen, mit der die Audio- und Videodaten jeweils in mindestens zwei gerätespezifisch verschiedenen Formaten auf dem Datenträger speicherbar sind, so dass die Daten auf dem Datenträger für mindestens zwei verschiedene Abspielgeräte lesbar sind. Wenn die Daten auf dem Datenträger von mindestens zwei verschiedenen Abspielgeräten lesbar sind, so ergibt sich für den Benutzer der Vorteil, dass er mit dem Abspielgerätetyp, den er besitzt eine größere Anzahl verschiedener Datenträger lesen kann. Wenn also beispiels- weise auf einem Datenträger die gleichen Audio- und Videodaten im MPEG-Format und im PSX-Format aufgezeichnet sind, kann diesen Datenträger sowohl ein Benutzer, der einen DVD-Player besitzt, als auch ein Benutzer, der eine Sony-Playstation besitzt, abspielen. Wenn darüber hinaus ein Musiktitel auf dem Datenträger zusätzlich in dem konventionellen Audioformat gespeichert ist, kann der Benutzer diesen Datenträger auch in einem CD-Player abspielen und den entsprechenden Musiktitel hören.Furthermore, a device for storing audio and video data on a data carrier is proposed according to the invention, with which the audio and video data can each be stored on the data carrier in at least two device-specific different formats, so that the data on the data carrier can be read by at least two different playback devices are. If the data on the data carrier can be read by at least two different playback devices, there is the advantage for the user that he can read a larger number of different data carriers with the type of playback device he has. If, for example, the same audio and video data are recorded in MPEG format and PSX format on a data carrier, this data carrier can be used by both a user who owns a DVD player and a user who owns a Sony Playstation owns, play. In addition, if a music title is additionally stored on the data carrier in the conventional audio format, the user can also play this data carrier in a CD player and listen to the corresponding music title.

Umgekehrt ergibt sich auch für den Hersteller einer mit mehreren Formaten bespielten CD, DVD oder dergleichen der Vorteil, dass er nicht verschiedene Tonträger produzieren muss und der hergestellte Tonträger für Benutzer mit unterschiedlichen Geräten abspielbar ist.Conversely, there is also the advantage for the manufacturer of a CD, DVD or the like recorded with several formats that he does not have to produce different sound carriers and the sound carrier produced can be played by users with different devices.

Bei einer bevorzugten Ausführungsform besteht der Datenträger aus einer Compact Disc (CD). Auf dieser CD sind mit bekannten Vorrichtungen und Verfahren Audio- und Videodaten speicherbar. Mit der erfindungsgemäßen Vorrichtung und dem entsprechendem erfindungsgemäßen Verfahren werden die Audio und Videodaten jeweils mit mindestens zwei gerätespezifisch verschiedenen Formaten auf der CD gespeichert. Gemäß einer ersten Ausführungsform werden zunächst Audiodaten in dem konventionellen digitalen Audioformat (Audiotrack oder dgl.) auf der CD abgespeichert. Daraufhin werden beispielsweise die Audiodaten zusammen mit den dazugehörigen Videodaten im MPEG-Format auf der CD abgespeichert. Die Videodaten sind in einem weiteren Format auf der CD gespeichert. Damit sind auf der CD in Richtung von der äußersten Spur zur innersten Spur zunächst Audiodaten im digitalen Audioformat und nachfolgend Audio- und Videodaten im MPEG-Format abgespeichert. Diese Aufnahmereihenfolge gewährleistet, dass ein konventioneller CD-Player das im Audioformat gespeicherte Musikstück abspielen kann. Konventionelle CD-Player erkennen für sie abspielbare CDs in der Regel nur dann, wenn zu Beginn der CD Daten im Audio- format gespeichert sind. Somit kann ein konventioneller CD-Player Audiodaten im Audioformat nicht abspielen, wenn sie hinter einem Datensatz anderen Formats auf der CD gespeichert sind. Wenn aber, wie im vorliegenden Fall, die Audiodaten im Audioformat zu Beginn der CD gespeichert sind, wird der konventionelle CD-Player die CD als lesbar erkennen und den Musiktitel abspielen können.In a preferred embodiment, the data carrier consists of a compact disc (CD). Audio and video data can be stored on this CD using known devices and methods. With the device according to the invention and the corresponding method according to the invention, the audio and video data are each stored on the CD with at least two device-specific different formats. According to a first embodiment, audio data is first stored in the conventional digital audio format (audio track or the like) on the CD. Thereupon, for example, the audio data are stored on the CD together with the associated video data in MPEG format. The video data is stored in a further format on the CD. This means that audio data in digital audio format and then audio and video data in MPEG format are stored on the CD in the direction from the outermost track to the innermost track. This recording order ensures that a conventional CD player can play the piece of music stored in the audio format. Conventional CD players usually only recognize playable CDs if data is stored in audio format at the beginning of the CD. This means that a conventional CD player cannot play audio data in audio format if it is saved on the CD after a data record of a different format. But if, as in the present case, the audio data in audio format at the beginning the CD is stored, the conventional CD player will recognize the CD as readable and can play the music track.

Die CD der ersten Ausfuhrungsform, bei der nach den Audiodaten im Audioformat auch Audio- und Videodaten im MPEG-Format gespeichert sind, kann auch von einem Video-CD- Player (VCD-Player) oder einem Computer mit entsprechendem CD-ROM-Laufwerk abgespielt werden. Sowohl der VCD-Player als auch der Computer verfügen nämlich über die Möglichkeit nicht nur das Audioformat zu lesen, sondern auch an beliebiger Stelle der CD Daten auszulesen. Somit ist es möglich, dass der VCD-Player bzw. der Computer, selbst wenn er die am Anfang der CD gespeicherten Daten nicht lesen könnte, an einer beliebigen Stelle der CD auf Daten zugreift, die in einem für ihn lesbaren Format abgespeichert sind. Dies bedeutet also, dass die oben beschriebene CD mit den in zwei verschiedenen Formaten abgespeicherten Daten von einem konventionellen CD-Player als auch von einem VCD- Player bzw. Computer gelesen werden können. D.h. vom CD-Player können die Audiodaten im digitalen Audioformat gelesen werden und vom VCD-Player bzw. Computer können die Audio- und Videodaten gelesen werden.The CD of the first embodiment, in which audio and video data are also stored in MPEG format after the audio data in audio format, can also be played by a video CD player (VCD player) or a computer with a corresponding CD-ROM drive become. Both the VCD player and the computer have the ability not only to read the audio format, but also to read data from anywhere on the CD. It is thus possible for the VCD player or the computer, even if it could not read the data stored at the beginning of the CD, to access data at any point on the CD which are stored in a format which is readable for it. This means that the CD described above with the data stored in two different formats can be read by a conventional CD player as well as by a VCD player or computer. That The audio data can be read from the CD player in digital audio format and the audio and video data can be read from the VCD player or computer.

Für den konkreten Falle eines Musikstücks mit passendem Videoclip bedeutet dies nun folgendes. Das Musikstück wird durch die erfindungsgemäße Vorrichtung nach dem erfindungs- gemäßen Verfahren am Beginn der CD im Audioformat abgespeichert. Nachfolgend werden die Audiodaten des Musikstücks zusammen mit den Videodaten des Videoclips im MPEG- Format auf der CD abgespeichert. Zumindest die Videodaten werden in einem weiteren Format zusätzlich auf dem Datenträger gespeichert. Die so bespielte CD wird in den konventionellen CD-Player eingelegt, welcher die CD als lesbar erkennt und abspielen kann, da die abzuspielenden Daten im Audioformat zu Beginn der CD aufgenommen sind. Wird dieselbe Musikvideo-CD in einen VCD-Player oder ein CD-ROM-Laufwerk eines Computers mit entsprechender Software eingelegt, so erkennt dieser die Audio- und Videodaten und kann den Videoclip zusammen mit dem Musikstück wiedergeben. Damit ist diese Musikvideo-CD in vorteilhafter Weise sowohl für den Besitzer eines konventionellen CD-Players als auch den Besitzer eines VCD-Players bzw. Computers mit CD-ROM-Laufwerk abspielbar. Es bedarf also nicht zwei verschiedener CDs für die verschiedenen Benutzer. Gemäß einer zweiten Ausfuhrungsform ist die CD neben dem konventionellen CD-Player auch für eine spezielle Sony-Playstation oder dergleichen lesbar. Dazu ist es wie bei der ersten Ausfuhrungsform notwendig, dass die Audiodaten des Musikstücks zu Beginn der CD im konventionellen Audioformat abgespeichert werden. Nachfolgend speichert die entspre- chende Vorrichtung Audio- und Videodaten im PSX-Format oder einem entsprechenden Format ab. Eine derartige CD wäre sinngemäß für einen konventionellen CD-Player und eine Sony-Playstation oder dergleichen abspielbar.For the specific case of a piece of music with a suitable video clip, this now means the following. The piece of music is stored in audio format by the device according to the invention using the method according to the invention at the beginning of the CD. The audio data of the piece of music are then stored on the CD together with the video data of the video clip in MPEG format. At least the video data is also stored on the data carrier in a further format. The CD recorded in this way is inserted into the conventional CD player, which recognizes the CD as readable and can play it, since the data to be played back are recorded in audio format at the beginning of the CD. If the same music video CD is inserted into a VCD player or a CD-ROM drive of a computer with the appropriate software, it recognizes the audio and video data and can play the video clip together with the piece of music. This music video CD can thus be played advantageously both for the owner of a conventional CD player and for the owner of a VCD player or computer with a CD-ROM drive. So there is no need for two different CDs for the different users. According to a second embodiment, in addition to the conventional CD player, the CD can also be read by a special Sony playstation or the like. For this purpose, as in the first embodiment, it is necessary for the audio data of the piece of music to be stored in the conventional audio format at the beginning of the CD. The corresponding device then stores audio and video data in PSX format or a corresponding format. Such a CD would be analogously playable for a conventional CD player and a Sony Playstation or the like.

Gemäß einer dritten Ausfuhrungsform der vorliegenden Erfindung werden nach den Audio- daten im digitalen Audioformat die Audio- und Videodaten zum einen im MPEG-Format und zum anderen im PSX-Format abgespeichert. Die derart hergestellte CD kann folglich auf dem konventionellen CD-Player, auf dem VCD-Player bzw. Computer und auf der Sony-Playstation abgespielt werden. Der Nutzen einer derartigen CD ist entsprechend vervielfacht.According to a third embodiment of the present invention, the audio and video data are stored on the one hand in MPEG format and on the other hand in PSX format after the audio data in digital audio format. The CD thus produced can consequently be played on the conventional CD player, on the VCD player or computer and on the Sony Playstation. The benefits of such a CD are multiplied accordingly.

Gemäß der vorliegenden Erfindung kann auch eine CD ohne die Audiodaten im konventionellen Audioformat hergestellt werden. Die Audio- und Videodaten in den verschiedenen Formaten können dann an beliebiger Stelle der CD abgespeichert werden.According to the present invention, a CD can also be produced in the conventional audio format without the audio data. The audio and video data in the various formats can then be stored anywhere on the CD.

Außer in den oben vorgestellten Formaten (MPEG und PSX) können die Audio- und Video- daten ersatzweise oder zusätzlich auch in anderen nicht-standardisierten Formaten abgespeichert werden, z.B. in VCD 3.0, Super VCD, HQ-VCD, CVD, Quicktime (Apple) etc.. Begrenzt durch den Speicherplatz können also entsprechend viele verschiedene Formate der Audio- und Videodaten auf der CD gespeichert werden. Fakultativ können die Audiodaten auch immer im konventionellen Audioformat, ggf. auch in Dolby Surround AC3, mit abge- speichert werden. Diese sind dann vorzugsweise zu Beginn der CD abzuspeichern, damit möglichst viele konventionelle CD-Player die Audiodaten lesen können.In addition to the formats presented above (MPEG and PSX), the audio and video data can be saved as an alternative or in addition in other non-standardized formats, e.g. in VCD 3.0, Super VCD, HQ-VCD, CVD, Quicktime (Apple) etc. .. Limited by the storage space, many different formats of audio and video data can be saved on the CD. Optionally, the audio data can always be saved in the conventional audio format, possibly also in Dolby Surround AC3. These should then preferably be saved at the beginning of the CD so that as many conventional CD players as possible can read the audio data.

Gemäß einer vierten Ausfuhrungsform der vorliegenden Erfindung besteht der Datenträger aus der digitalen Video Disc (DVD), die mit einer entsprechenden Vorrichtung mit Audio- und Videodaten beschrieben wird. Prinzipiell sind auf einer DVD Audio- und Videodaten in den gleichen, oben beschriebenen Datenformaten speicherbar. Somit gilt das oben für die CD Gesagte in gleicher Weise für die DVD. Es besteht lediglich die Einschränkung, dass die meisten derzeit verfügbaren CD- und VCD-Player DVDs nicht abspielen können. Somit stellt sich der multimediale Nutzen eines mit mehreren Datenformaten bespielten Datenträgers bei der DVD nicht in gleicher Weise ein wie bei der CD.According to a fourth embodiment of the present invention, the data carrier consists of the digital video disc (DVD), which is written with a corresponding device with audio and video data. In principle, audio and video data can be stored on a DVD in the same data formats described above. So what has been said above for the CD applies equally to the DVD. The only limitation is that the most currently available CD and VCD players cannot play DVDs. Thus, the multimedia use of a data carrier recorded with several data formats does not appear on the DVD in the same way as on the CD.

Vorzugsweise wird für die CD ein mehrlagiger Hybrid-Rohling verwendet. Dies ermöglicht, dass die Daten in den jeweiligen Lagen mit unterschiedlichen Formaten abgespeichert werden können und somit der Gesamtspeicherplatz der CD zunimmt. Beispielsweise werden hierzu Daten im Standard-Audioformat in einer untersten Lage abgespeichert. In einer darüberlie- genden, für den CD-Player unsichtbaren Schicht werden Daten im MPEG-Format aufge- zeichnet. Somit kann ein CD-Player die Daten in der untersten Lage lesen und ein DVD- Player die darüberliegenden Daten im MPEG-Format. Selbstverständlich können in einer Lage auch Daten in mehreren Formaten aufgezeichnet werden.A multi-layer hybrid blank is preferably used for the CD. This enables the data to be saved in the respective layers with different formats and thus the total storage space on the CD increases. For example, data in the standard audio format is stored in a lowest position. In an overlying layer that is invisible to the CD player, data is recorded in MPEG format. This means that a CD player can read the data in the lowest position and a DVD player can read the data above in MPEG format. Of course, data in several formats can also be recorded in one layer.

Derzeit stellt sich noch das Problem, dass einzelne CD-Player älteren Baujahrs derartige Hybrid-CDs nicht auslesen können. Die Ursache liegt darin, dass die Laserköpfe älterer CD- Player gegenüber der CD-Oberfläche vertikal fest angeordnet sind, während jüngere CD- Player wie auch DVD-Player und Computer-Lesegeräte vertikal bewegliche Laserköpfe besitzen, um unterschiedliche Lagen abzutasten. Durch einen entsprechenden Lagenaufbau und/oder geeignete Materialwahl der Hybrid-CD lässt sich dieses Problem lösen, so dass auch ältere CD-Player Hybrid-CDs lesen können.At the moment there is still the problem that individual CD players of older construction years cannot read out such hybrid CDs. The reason for this lies in the fact that the laser heads of older CD players are arranged vertically fixed in relation to the CD surface, while younger CD players as well as DVD players and computer readers have vertically movable laser heads in order to scan different positions. This problem can be solved by an appropriate layer structure and / or a suitable choice of material for the hybrid CD, so that older CD players can also read hybrid CDs.

Die oben angeführten Formate dienen lediglich der Erläuterung und sind durch beliebig andere Formate ersetzbar. In gleicher Weise ist man nicht darauf beschränkt lediglich einen Musiktitel und eine dazugehörige Videopassage auf einen Datenträger aufzuzeichnen, sondern es kann eine beliebige Anzahl und Kombination von Audio- und Videostücken lediglich begrenzt durch den Speicherplatz des Datenträgers aufgenommen werden. So können beispielsweise auch sog. Werbe- und Kinotrailer kombiniert mit Videoclips von Musikinterpreten auf einer CD oder DVD aufgenommen werden.The formats listed above are for explanation only and can be replaced by any other format. In the same way, one is not limited to recording only a music title and an associated video passage on a data carrier, but any number and combination of audio and video pieces can be recorded only to a limited extent by the storage space of the data carrier. For example, so-called advertising and cinema trailers combined with video clips from music performers can be recorded on a CD or DVD.

Des Weiteren ist der Tonträger, d.h. die CD, DVD oder dgl., nicht auf die üblichen physischen Größen, z.B. rund 5-Zoll-Scheibe, beschränkt. Auch andere Formen des Tonträgers, z.B. Scheibe mit dem Umriss eines Konzertflügels, sind denkbar. Furthermore, the sound carrier, i.e. the CD, DVD or the like, not to the usual physical sizes, e.g. around 5-inch disc, limited. Other forms of the sound carrier, e.g. Discs with the outline of a concert grand are conceivable.
