Beschreibungdescription
Verfahren zum Übertragen in einer strömenden Weise von Daten und Gerät für die Anwendung in einem nach einem solchen Verfahren arbeitenden SystemMethod for transferring in a flowing manner of data and device for use in a system operating according to such a method
Die Erfindung betrifft ein Verfahren zum Übertragen in einer strömenden Weise von Daten gemäß dem Oberbegriff des Anspruchs 1 und ein Gerät für die Anwendung in einem nach einem solchen Verfahren arbeitenden System gemäß dem Anspruch 9.The invention relates to a method for transmitting in a flowing manner of data according to the preamble of claim 1 and a device for use in a system operating according to such a method.
In der Unterhaltungsindustrie gibt es den bekannten Fall, dass von einer Datenquelle über. eine Übertragungsstrecke Daten zu einer Datensenke zu übertragen sind. Bei den Daten handelt es sich dabei um Audio-, Video- oder sonstige entsprechende Daten. Diese Daten werden in zweckdienlicher Form, d. h. in einer strömenden Weise (engl.: Streaming) übertragen.In the entertainment industry, there is a known case that is from a data source. a transmission link data is to be transmitted to a data sink. The data is audio, video or other corresponding data. This data will be presented in an appropriate form, i.e. H. broadcast in a streaming manner.
Die Daten können vor einer Wiedergabe durch eine entsprechende Ausgabe-Einheit vorab vom Internet oder von einer CD in einen Platten-Speicher eines Rechners kopiert werden. Der Platten-Speicher kann beispielsweise ein Festplatten-Speicher des Rechners oder eine Read/Write-CD in einem Read/Write- Laufwerk des Rechners sein.Before being played back, the data can be copied beforehand from the Internet or from a CD into a disk memory of a computer by a corresponding output unit. The disk memory can be, for example, a hard disk memory of the computer or a read / write CD in a read / write drive of the computer.
Es kann auch sein, dass die Daten als sogenannter Stream online aus dem Internet empfangen und direkt an die Ausgabe- Einheit für eine Wiedergabe weitergeleitet werden. Ein Beispiel für eine solche Funktion ist unter der Bezeichnung „Internet Radio' bekannt.It may also be the case that the data is received online as a so-called stream from the Internet and is forwarded directly to the output unit for playback. An example of such a function is known as "Internet radio".
Beim Internet Radio werden entsprechend komprimierte Daten aus dem Internet auf den lokalen Platten-Speicher eines betreffenden Rechners geladen. Die Komprimierung beruht dabei auf einer bekannten Standardmethode, welche beispielsweise unter den Formatnamen MP3, MP3 Pro, MPEG4 AAC, Windows Media Audio bzw. Real Audio bekannt sind.With Internet Radio, appropriately compressed data from the Internet is loaded onto the local disk storage of a computer in question. The compression is based on a known standard method, for example are known under the format names MP3, MP3 Pro, MPEG4 AAC, Windows Media Audio and Real Audio.
Die Wiedergabe dieser Daten erfolgt durch eine entsprechende Dekodierung durch einen entsprechenden Software-Dekoder und Ausgabe der gespeicherten Daten durch eine entsprechende Ausgabe-Einheit. Die Ausgabe kann durch eine an den Rechner wenigstens kurzzeitig angeschlossene Ausgabe-Einheit erfolgen. Beispielsweise durch einen mobil tragbaren MP3-Player (MP3- Spieler) , in dessen Speicher die Daten wiederum übertragen worden sind. Sie kann aber auch über eine entsprechende vorhandene interne Ausgabe-Einheit des Rechners erfolgen. Es ist auch möglich, dass die Wiedergabe der Daten über eine Ausgabe-Einheit erfolgt, die weiter ab von dem besagten Rechner angeordnet aber nicht mobil tragbar ist. Das kann beispielsweise eine Heim-Audio und/oder Video-Anlage sein. In diesem Fall kann es auch noch sein, dass eine Luftübertragungsstrecke zu überwinden ist, wobei diese Übertragungsstrecke beispielsweise mit Hilfe der bekannten HomeRF-Technik bei entsprechender Ausgestaltung der an der Aktion beteiligten Geräte überbrückt wird.This data is reproduced by a corresponding decoding by a corresponding software decoder and output of the stored data by a corresponding output unit. The output can be made by an output unit connected to the computer at least for a short time. For example, by a portable MP3 player (MP3 player), in the memory of which the data has in turn been transferred. However, it can also take place via a corresponding existing internal output unit of the computer. It is also possible for the data to be reproduced via an output unit which is arranged further away from said computer but cannot be carried on a mobile device. This can be a home audio and / or video system, for example. In this case, it may also be the case that an air transmission path has to be overcome, this transmission path being bridged, for example, using the known HomeRF technology with the appropriate design of the devices involved in the action.
Ein Problem besteht neben der Tatsache, dass die Daten in komprimierter Form vorliegen, dass es eine stetige Evolution bezüglich der Kompressionsverfahren gibt. Ziel der Kompressionsverfahren ist es, eine höhere oder gleiche Qualität bei der Ausgabe der Daten zu haben bei einem immer geringeren Speicherbedarf für diese Daten.A problem is, besides the fact that the data is in a compressed form, that there is a constant evolution regarding the compression methods. The aim of the compression process is to have a higher or equal quality in the output of the data with an ever smaller storage requirement for this data.
Wie schon erwähnt, können alternativ zu einem Herunterladen und Wiedergeben der Daten mit konkurrierenden Verfahren entsprechende Daten online aus dem Internet gestreamt und dekodiert werden.As already mentioned, as an alternative to downloading and reproducing the data, corresponding data can be streamed online from the Internet and decoded using competing methods.
Der Umstand, dass der Kunde hierdurch Musik lediglich am Rechner hören kann, hat schließlich beispielsweise zur Entstehung der Produktgruppe „MPS-Player* geführt. Hier können lokal auf einem Rechner gespeicherte MP3-Dateien auf ein Speichermedium des nur für den Übertrag an den Rechner angeschlossenen MP3-Players übertragen und dann später an einem anderen Ort angehört werden. Damit sind die bisher lokal auf einem Rechner gespeicherten Daten quasi mobil geworden und können „herumgetragen* und mobil abgespielt werden.The fact that the customer can only listen to music on the computer has led to the creation of the "MPS-Player *" product group. Here you can MP3 files stored locally on a computer are transferred to a storage medium of the MP3 player that is only connected to the computer for transmission and can then be listened to later at another location. This means that the data previously stored locally on a computer has become virtually mobile and can be "carried around" and played back on the go.
Dabei bleiben die Daten auf dem MP3-Player wie auch im Falle der Aufbewahrung im Rechner komprimiert, weil insbesondere der MP3-Player nur eine begrenzte Speicherkapazität hat. Das MP3-Format beispielsweise benötigt für eine Wiedergabe in CD- Qualität ca. 1 MB pro Minute Wiedergabezeit. Damit die Daten wiedergegeben werden können, weist beispielsweise der MP3- Player einen eingebauten MP3-Software-Dekoder auf.The data on the MP3 player remains compressed, as is the case when it is stored in the computer, because the MP3 player in particular has only a limited storage capacity. The MP3 format, for example, requires approximately 1 MB per minute of playback time for CD quality playback. So that the data can be played back, for example, the MP3 player has a built-in MP3 software decoder.
In jüngster Zeit kündigen sich erste Modelle einer Produktgruppe namens „Streaming Media Devices* an, welche die Daten über Funk zu einem Konverter „streamen* . Dieser Konverter hat kein eigenes Massen-Speichermedium und dekodiert die empfangenen Daten in Echtzeit. Im Prinzip ist dieser Konverter wie der MP3-Player aufgebaut. Er kann idealerweise an eine heimische Audio-Anlage angeschlossen werden. Ein Kunde kann auf diese Weise seine Musikstücke, die beispielsweise auf der Festplatte seines Rechners abgelegt sind, auch über seine Heim-Audio-Anlage hören.Recently, the first models in a product group called "Streaming Media Devices *" have been announced, which "stream" the data via radio to a converter. This converter does not have its own mass storage medium and decodes the received data in real time. In principle, this converter is structured like the MP3 player. Ideally, it can be connected to a home audio system. In this way, a customer can also hear his pieces of music, which are stored, for example, on his computer's hard drive, via his home audio system.
Ein solcher Konverter ist beispielsweise unter dem Begriff „simplefi* von der Fa. SimpleDevices bzw. Motorola bekannt, bei welchem es sich um einen drahtlosen digitalen Audio-Empfänger handelt.Such a converter is known, for example, by the term “simplefi *” from SimpleDevices or Motorola, which is a wireless digital audio receiver.
Das erwähnte Gerät empfängt über eine Luft-Übertragungsstrecke die von einem Rechner in einer strömenden Weise übertragenen Daten in einer als Empfänger ausgebildeten Eingangsschaltung mittels einer entsprechenden PC-Applikation. Das Übertragungsmedium ist hierbei die Funkübertragungstechnik HomeRF. Das Gerät beinhaltet einen entsprechenden Software- Dekoder, hier einen MP3-Software-Dekoder, welcher den ankommenden Audio-Stream in ein Standard-Stereosignal konvertiert. Dieses Signal kann von einem herkömmlichen HiFi-Verstärker wiedergegeben werden. Das Gerät funktioniert daher als eine Datensenke, insbesondere als ein Streaming-Converter bzw. Ström-Konverter .The above-mentioned device receives the data transmitted by a computer in a flowing manner via an air transmission link in an input circuit designed as a receiver by means of a corresponding PC application. The transmission medium is the HomeRF radio transmission technology. The device contains a corresponding software Decoder, here an MP3 software decoder, which converts the incoming audio stream into a standard stereo signal. This signal can be reproduced by a conventional HiFi amplifier. The device therefore functions as a data sink, in particular as a streaming converter.
Ein soweit beschriebener Stand der Technik ist in der Figur 1 in prinzipieller Form dargestellt. Im Zusammenhang mit der obigen Beschreibung ist die Figur 1 selbsterklärend, weshalb sie an dieser Stelle nicht nochmals explizit beschrieben wird. 'A state of the art described so far is shown in principle in FIG. 1. In connection with the above description, FIG. 1 is self-explanatory, which is why it is not explicitly described again here. '
Auf Grund der Tatsache, dass die standardisierten Komprimierungsverfahren immer mehr werden und entsprechende Geräte wie z. B. ein Ström-Konverter all diese Verfahren beherrschen soll, werden diese Geräte mit möglichst vielen Software-Dekodern für einen jeweiligen möglichen Anwendungsfall ausgestattet, um letztlich möglichst lange mit diesem Gerät technisch auf der Höhe zu sein. Ein anderer Gesichtspunkt ist, dass sich ein Hersteller mit seinem Produkt von einem Konkurrenten abheben möchte .Due to the fact that the standardized compression methods are becoming more and more and corresponding devices such. For example, if a flow converter is to master all of these methods, these devices are equipped with as many software decoders as possible for a respective possible application, in order to be technically up to date with this device for as long as possible. Another aspect is that a manufacturer wants his product to stand out from a competitor.
Nachteilig dabei ist, dass selbst dann, wenn bei der Auslieferung eines Streaming Converters alle zur Zeit für Deko pri- mierungszwecke verwendeten Software-Dekoder eingebaut werden, es nach kurzer Zeit schon wieder sein kann, dass es neue Software-Dekoder gibt, die aktueller sind. Das Vorsehen der Möglichkeit einer nachträglichen Aktualisierung des Stream Converters oder allgemein eines betreffenden Gerätes ist aufwendig und umständlich.The disadvantage here is that even if all of the software decoders currently used for decompression purposes are installed when a streaming converter is delivered, it can happen again after a short time that there are new software decoders that are more up-to-date , The provision of the possibility of a subsequent update of the stream converter or of a device in general is complex and cumbersome.
Aufgabe der vorliegenden Erfindung ist es, ausgehend von einem Verfahren der eingangs genannten Art ein Verfahren zum Übertragen in einer strömenden Weise von Daten anzugeben, das eine stete Aktualität für die nach. diesem Verfahren arbeitende Geräte garantiert. Ferner ist es Aufgabe der vorliegen- den Erfindung, ein Gerät anzugeben, das für die Anwendung in einem nach einem solchen Verfahren arbeitenden System einsetzbar ist.It is an object of the present invention, based on a method of the type mentioned at the outset, to specify a method for transmitting data in a flowing manner, which is constantly up-to-date. guaranteed equipment operating this process. It is also the task of the present the invention to provide a device that can be used for use in a system operating according to such a method.
Bezüglich des Verfahrens wird die Aufgabe dadurch gelöst, dass vor der Übertragung der Daten die Datenkompression gemäß einer Standardmethode aufgehoben wird.With regard to the method, the object is achieved in that the data compression is released according to a standard method before the data is transmitted.
Bezüglich des Gerätes wird die Aufgabe dadurch gelöst, dass auf der Seite der Datensenke, die durch das Gerät verkörpert ist, eine Eingangsschaltung vorgesehen ist wenigstens zum Ü- bernehmen von unkomprimiert und in einer strömenden Weise ü- bertragenen Daten und eine Ausgangsschaltung vorgesehen ist zum technischen Aufbereiten der übernommenen Daten für eine Widergabe in einer externen und/oder internen Ausgabe-Einheit.With regard to the device, the object is achieved in that on the side of the data sink which is embodied by the device, an input circuit is provided at least for the transfer of uncompressed data which is transmitted in a flowing manner, and an output circuit is provided for technical purposes Preparation of the transferred data for replay in an external and / or internal output unit.
Der Vorteil bezüglich des Verfahrens liegt darin, dass auf der Seite der Datensenke keine Software-Dekoder vorgesehen sein müssen, so dass diese auch nicht veralten können bzw. zu aktualisieren sind.The advantage with regard to the method lies in the fact that no software decoders have to be provided on the side of the data sink, so that they cannot be outdated or have to be updated.
Der Vorteil bezüglich des Gerätes liegt darin, dass das Gerät in der Lage ist, unabhängig von aktuellen Software-Dekodern arbeiten zu können und dass es dazu auch noch wesentlich günstiger herstellbar ist, weil der Aufwand für das Vorsehen und Betreiben von Software-Dekodern nicht notwendig ist.The advantage with regard to the device is that the device is able to work independently of current software decoders and that it is also much cheaper to manufacture because the effort required to provide and operate software decoders is not necessary is.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand von Unteransprüchen.Advantageous embodiments of the invention are the subject of dependent claims.
Bezüglich des Gerätes kann zwar doch wieder ein Dekoder zwischen der Eingangs- und Ausgangsschaltung vorgesehen sein, der an einen auf der Seite der Datenquelle gegebenenfalls vorgesehenen Enkoder für eine Datenkompression gemäß einer gewählten Spezialmethode angepasst ist. Dieser Dekoder ist aber ein Dekoder für eine Spezialmethode, die einmal gewählt und dann nicht mehr verändert wird. Dieser Dekoder hat die Aufgabe, dass wenn doch die Daten in einer komprimierten Form übertragen werden sollen, dies möglich ist. Diese Komprimierung ist aber unabhängig von einem Standard, das heißt, die -verschiedenen Firmen können z. B. für sich alleine eine gewünschte Komprimierung verwenden.Regarding the device, a decoder can indeed be provided between the input and output circuit, which is adapted to an encoder, optionally provided on the side of the data source, for data compression according to a selected special method. However, this decoder is a decoder for a special method that is chosen once and then no longer changed. This decoder has the task that if the data are to be transmitted in a compressed form, this is possible. This compression is independent of a standard, that is, the different companies can e.g. B. use a desired compression on its own.
Bezüglich des Verfahrens ist ein Vorteil, dass die zu übertragenden Daten aus Audiodaten und/oder Videodaten und/oder entsprechenden sonstigen Daten bestehen können, so dass alle möglichen Anwendungsfälle abgedeckt werden können.With regard to the method, it is an advantage that the data to be transmitted can consist of audio data and / or video data and / or corresponding other data, so that all possible applications can be covered.
Ein anderer Vorteil ist, dass es egal ist, welche Datenkompression gemäß einer Standardmethode auf der Seite der Datenquelle eingesetzt wird, da alle Datenkompressionsmethoden letztlich zu einer unkomprimierten oder höchsten vom Nutzer selbst vorgegebenen komprimierten Übertragung der Daten, also gemäß einer vom Nutzer selbst erschaffenen Spezialmethode, kommt, auf die er sich dann aber auch selbst mit einem entsprechenden Enkoder auf der Seite der Datenquelle und einem Dekoder auf der Seite der Datensenke einstellen kann, und zwar so lange, wie er selbst es möchte. Es spielt also keine Rolle mehr, ob es bezüglich einer standardisierten Datenkompressionsmethode zu einer Aktualisierung oder ob es gar zu einer neuen standardisierten Datenkompressionsmethode kommt. Bezogen auf die Seite der Datensenke bleibt ein nach dem Verfahren gemäß der Erfindung arbeitendes Gerät stets verwendbar.Another advantage is that it does not matter which data compression is used according to a standard method on the side of the data source, since all data compression methods ultimately result in an uncompressed or highest compressed transmission of the data specified by the user, i.e. according to a special method created by the user, comes to which he can then adjust himself with a corresponding encoder on the side of the data source and a decoder on the side of the data sink, and for as long as he wants. It therefore no longer matters whether there is an update with regard to a standardized data compression method or whether there is even a new standardized data compression method. With respect to the side of the data sink, a device operating according to the method according to the invention always remains usable.
Die Übertragung der Daten über eine Luftstrecke stellt kein Problem für die Realisierung der Erfindung dar. Dabei kann auch ohne weiteres die bekannte HomeRF-Technik zur Anwendung kommen.The transmission of the data over an air route is not a problem for the implementation of the invention. The known HomeRF technology can also be used without any problems.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand einer Zeichnung näher erläutert. Darin zeigen. Figur 1 ein nach dem Stand der Technik aufgebautes System in prinzipieller Form, undAn exemplary embodiment of the invention is explained in more detail below with reference to a drawing. Show in it. Figure 1 is a system constructed in accordance with the prior art in principle, and
Figur 2 ein nach der' Erfindung aufgebautes System in prinzipieller Form, das im übrigen dem System der Figur 1 entspricht.Figure 2 shows a system according to the ' invention in principle, which otherwise corresponds to the system of Figure 1.
Die Figuren 1 und 2 zeigen in einer Gegenüberstellung den Standes der Technik und die Erfindung. Die Figuren sind selbsterklärend. Insbesondere ist die Figur 1 eingangs im Zusammenhang mit dem Stand der Technik schon erklärt worden. An dieser Stelle wird daher nur noch auf den Unterschied zwischen der Erfindung und dem Stand der Technik eingegangen.Figures 1 and 2 show a comparison of the prior art and the invention. The figures are self-explanatory. In particular, FIG. 1 has already been explained in connection with the prior art. At this point, therefore, only the difference between the invention and the prior art will be discussed.
Der Unterschied besteht auf der Seite der Datensenke, zu der alles ab dem Ström-Konverter zu zählen ist. Der Ström-Konverter oder auch Stream Converter weist keinen Software Dekoder auf, der die in strömender Weise übertragenen Daten, die gemäß einer Standardmethode komprimiert sind, wieder dekomprimiert. Dies ist nicht nötig, wenn auf der Seite der Datenquellen, zu der alles gehört, was vor der Übertragungsstrecke angeordnet ist, die zu übertragenden Daten durch den dort schon vorhandenen Software-Dekoder dekodiert wird. Auf der Seite der Datenquelle muss ein solcher Software-Dekoder vorhanden sein, weil es dort die Regel ist, die Daten wiederzugeben. Es ist beim Stand der Technik nur so, dass zur Übertragung der Daten der Software-Dekoder ausgelassen wird, um die Daten komprimiert zu übertragen. Das zieht die Notwendigkeit nach sich, auf der Seite der Datensenke ebenfalls einen Software-Dekoder vorzusehen.The difference is on the side of the data sink, which includes everything from the Ström converter. The Ström converter or stream converter does not have a software decoder which decompresses the data transmitted in a streaming manner, which are compressed according to a standard method. This is not necessary if the data to be transmitted is decoded by the software decoder already present on the data source side, which includes everything that is arranged in front of the transmission path. Such a software decoder must be available on the data source side because it is the rule there to reproduce the data. In the prior art, it is only the case that the software decoder is omitted for the transmission of the data in order to transmit the data in compressed form. This entails the need to also provide a software decoder on the side of the data sink.
Es gibt aber keine Notwendigkeit, die Daten komprimiert zu übertragen, wenn die Daten sofort wiedergegeben werden. Die Übertragungsgeschwindigkeit ist groß genug, dass auch der erhöhte Anfall von Datenmenge für eine in Realzeit ablaufende Wiedergabe verarbeitbar ist. Dies umso mehr, als die Zeit für eine Dekodierung eingespart wird. Es wird also nicht nur der Software-Dekoder selbst auf der Seite der Datensenke einge- spart, wodurch sich wiederum die Hardware und. die Steuerung vereinfacht. Außerdem spielt es keine Rolle, welche standardisierte Kompressionsmethode auf der Seite der Datenquelle eingesetzt wird, da immer unkomprimierte Daten übertragen werden.However, there is no need to transmit the data compressed if the data is played back immediately. The transmission speed is high enough that the increased amount of data can also be processed for real-time playback. All the more so since the time for decoding is saved. It is not just the software decoder itself that is inserted on the side of the data sink. saves, which in turn reduces the hardware and . control simplified. In addition, it does not matter which standardized compression method is used on the data source side, since uncompressed data is always transmitted.
Allerdings besteht auch die Möglichkeit, auf der Seite einen beliebigen Enkoder auf der Seite der Datenquelle für den Einsatz einer speziellen Kompressionsmethode bei der Übertragung der Daten einzusetzen. Das zieht allerdings nach sich, dass sich auf der Seite der Datenquelle ein entsprechender Dekoder befindet. Dieser Umstand ändert aber an der Gesamtsituation nichts, da diese Maßnahme eine individuelle Maßnahmen ist, das heißt eine herstellerabhängige Maßnahme. Der Hersteller selbst bleibt bezüglich standardisierter Kompressionsmethoden unabhängig.However, it is also possible to use any encoder on the side of the data source for the use of a special compression method for the transmission of the data. However, this means that there is a corresponding decoder on the data source side. However, this fact does not change the overall situation, since this measure is an individual measure, that is, a manufacturer-dependent measure. The manufacturer remains independent with regard to standardized compression methods.
Angemerkt sei noch, dass die Widergabe-Einheit bzw. die Ausgabe-Einheit auf der Seite der Datenquelle nicht zwangsläufig separiert sein muss sondern ohne weiteres auch in dem Ström- Konverter integriert sein kann. It should also be noted that the playback unit or the output unit on the side of the data source does not necessarily have to be separated, but can also be easily integrated into the flow converter.
