Abstract

The data transmission method involves specifying a priority for a transmission process and sending a data packet with a length depending on the specified priority. Data are received with a second priority and transmission is interrupted if the second priority is higher than the first. A manual operating process causes a transmission at the highest priority. An independent claim is also included for the following: (a) an arrangement for sending data in a hearing aid system (b) a hearing aid with an inventive arrangement (c) and a remote controller with an inventive arrangement.

Description

Die vorliegende Erfindung betrifft Verfahren und Vorrichtungen zum Senden von Daten in einem Hörgerätesystem.The present invention relates to methods and apparatus for transmitting data in a hearing aid system.

Die drahtlose Kommunikation eines Hörgeräts mit einem anderen als auch mit einer weiteren Kommunikationsschnittstelle muss spezielle Anforderungen erfüllen, die beispielsweise durch die sehr eingeschränkte verfügbare Sendeenergie eines im Hörgerät befindlichen Transceivers als auch durch die häufig aus räumlichen Gründen sehr uneffektiven Antennen verursacht werden.The wireless communication of a hearing aid with another as well as with another communication interface must meet special requirements, which are caused for example by the very limited available transmission energy of a transceiver located in the hearing aid as well as by the often inefficient for spatial reasons antennas.

Die in anderen Anwendungsfeldern realisierten Lösungen greifen einerseits auf Multikanal oder Zeitscheibenverfahren zurück. Wenn andererseits ein Einkanalübertragungssystem verwendet wird, kann bei hinreichenden Sendereichweiten und Übertragungsbandbreiten aller beteiligten Kommunikationsteilnehmer in der Regel sichergestellt werden, dass der drahtlose Übertragungskanal bei Einsetzen eines Übertragungsvorgangs frei ist. Aus energetischen und räumlichen Gründen sind diese Verfahren, die beispielsweise in modernen digitalen Übertragungssystemen (Bluetooth, DECT etc.) Verwendung finden, für Hörgeräteanwendungen nicht geeignet. Die im Hörgerätesektor gebräuchlichen FM-Übertragungssysteme stellen in der Regel reine Punkt-zu-Punkt-Übertragungssysteme mit einer Übertragungsebene für eine einzelne Anwendung dar, die kontinuierlich analoge Signale übertragen.On the one hand, the solutions implemented in other fields of application draw on multi-channel or time-slicing methods. On the other hand, if a single-channel transmission system is used, with sufficient transmission ranges and transmission bandwidths of all communication participants involved, it can usually be ensured that the wireless transmission channel is free when a transmission process is initiated. For energy and space reasons, these methods, which are used for example in modern digital transmission systems (Bluetooth, DECT, etc.) are not suitable for hearing aid applications. The commonly used in the hearing aid sector FM transmission systems are usually pure point-to-point transmission systems with a transmission level for a single application that continuously transmit analog signals.

In diesem Zusammenhang ist aus der Druckschrift DE 195 44 546 ein Hörgerät mit mehreren analogen Eingängen und einem zusätzlichen digitalen Eingang bekannt. Es besteht die Möglichkeit, mehrere digitale, am zusätzlichen Eingang des Hörgeräts eingespeiste Signale durch einen Multiplexer weiter zu verarbeiten und einem Signalprozessor des Hörgeräts zuzuleiten.In this context, from the document DE 195 44 546 a hearing aid with multiple analog inputs and an additional digital input known. It is possible to further process a plurality of digital signals fed in at the additional input of the hearing device through a multiplexer and to forward them to a signal processor of the hearing device.

Hierdurch können räumlich getrennt angeordnete Mikrofonsignale von Stereomikrofonen auf digitale Art und Weise schnell und störungsfrei empfangen und weiterverarbeitet werden.As a result, spatially separated microphone signals from stereo microphones can be digitally received and processed quickly and without interference.

Des Weiteren ist in der nachveröffentlichten Druckschrift DE 102 01 068 ein Verfahren zum Kommunizieren eines Hörgeräts mit externen Funkschnittstellen beschrieben, bei dem Adressdaten und/oder Kanaldaten bezüglich mehrerer Signalquellen in einer Speichereinrichtung gespeichert werden. Durch ein prioritätsgetriebenes Adressverwaltungssystem kann der Hörgeräteträger sehr komfortabel die Kommunikation mit einer Funkschnittstelle höchster Priorität automatisch aufnehmen.Furthermore, in the post-published document DE 102 01 068 describes a method for communicating a hearing device with external radio interfaces, in which address data and / or channel data relating to a plurality of signal sources are stored in a memory device. Through a priority-driven address management system, the hearing aid wearer can very comfortably record the communication with a radio interface of the highest priority automatically.

Aus der Druckschrift US 4,920,570 A ist ein modulares Hörhilfesystem bekannt. Über ein Schaltmodul ist ein Hörermodul mit den Signalen mehrerer entfernter Signalquellen versorgbar. Das Schaltmodul weist einen Empfänger, einen Kanalwählschalter und einen Sender auf. Signale niederer Priorität werden von dem Schaltmodul nicht weiter übertragen oder in der Signalstärke reduziert, wenn ein Signal höherer Priorität ansteht und zu dem Hörermodul übertragen werden muss.From the publication US 4,920,570 A is a modular hearing aid known. About a switching module, a receiver module with the signals of several remote signal sources can be supplied. The switching module has a receiver, a channel selector and a transmitter. Lower priority signals are no longer transmitted or reduced in signal strength by the switching module when a higher priority signal is pending and needs to be transmitted to the handset module.

Darüber hinaus zeigt die Druckschrift WO 99/03254 eine PCN-Einheit (Personal Communication Node) zum Empfangen und Senden von Signalen über eine drahtlose Verbindung von und zu einem Hörgerät. Die Signale werden entsprechend einer Prioritätsliste verarbeitet. Bei einer Interruptanfrage mit hoher Priorität wird eine laufende Signalverarbeitung niedrigerer Priorität unterbrochen.In addition, the document shows WO 99/03254 a Personal Communication Node (PCN) unit for receiving and transmitting signals over a wireless connection to and from a hearing aid. The signals are processed according to a priority list. In a high priority interrupt request, current lower priority signal processing is interrupted.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, ein Kommunikationssystem für Hörgeräte zu schaffen, das den speziellen Anforderungen an Hörgeräte genügt und insbesondere hinsichtlich des Energieverbrauchs optimiert ist.The object of the present invention is thus to provide a communication system for hearing aids that meets the special requirements for hearing aids and is optimized in particular with regard to energy consumption.

Erfindungsgemäß wird diese Aufgabe gelöst durch ein Verfahren zum Senden von Daten in einem Hörgerätesystem durch Vergeben einer Priorität für einen Sendevorgang und Senden eines Datenpakets, dessen Länge von der vergebenen Priorität in vorbestimmter Weise abhängt.According to the invention, this object is achieved by a method for transmitting data in a hearing aid system by assigning a priority for a transmission and transmission of a data packet whose length depends on the assigned priority in a predetermined manner.

Eine entsprechende Vorrichtung zum Senden von Daten für ein Hörgerätesystem besitzt eine Vergabeeinrichtung zum Vergeben einer Priorität für einen Sendevorgang, eine Bereitstellungseinrichtung zum Bereitstellen von zu sendenden Daten und einer Sendeeinrichtung zum Senden der bereitgestellten Daten, wobei in der Bereitstellungseinrichtung die zu sendenden Daten in einem Datenpaket, dessen Länge von der vergebenen Priorität in vorbestimmter Weise abhängt bereitstellbar sind.A corresponding device for transmitting data for a hearing aid system has an allocation device for assigning a priority for a transmission process, a provision device for providing data to be transmitted, and a transmission device for transmitting the provided data, wherein in the delivery device the data to be transmitted are stored in a data packet, whose length depends on the assigned priority in a predetermined manner.

Gemäß der vorliegenden Erfindung ist es damit möglich, der manuellen Bedienung eines Hörgeräts vor anderen Kommunikationen zwischen den Hörgeräten Vorrang zu verschaffen, indem den aufgrund der Bedienung zu übertragenden Daten die höchste Priorität und damit die größte Datenpaketlänge gegeben wird. Folglich müssen diejenigen Komponenten des Hörgerätesystems, die eine derartig hochpriore Nachricht empfangen, zumindest für eine gewisse Zeit ihre Sendeaktivität einstellen. Aus diesem Grund ist erfindungsgemäß vorgesehen ein Hörgerät wie im Anspruch 18.According to the present invention, it is thus possible to give priority to the manual operation of a hearing aid prior to other communications between the hearing aids by giving the highest priority and thus the largest data packet length to the data to be transmitted due to the operation. Consequently, those components of the hearing aid system that receive such a high-priority message, at least for a certain time to stop their transmission activity. For this reason, the invention provides a hearing aid as in claim 18.

Es wird also hier von einem Übertragungssystem auf der Basis beispielsweise einer elektromagnetischen, Infrarot- oder Ultraschall-Übertragung ausgegangen, das aufwandbedingt und aufgrund einer begrenzten Übertragungskapazität keinen Zugriff auf mehrere Übertragungskanäle oder eine Aufteilung nach einem Zeitscheibenverfahren hat. Die Übertragungssignale werden vorzugsweise über einen einzigen Übertragungskanal transferiert.It is therefore assumed here by a transmission system based on, for example, an electromagnetic, infrared or ultrasonic transmission, due to the complexity and due to a limited transmission capacity no access to multiple transmission channels or a division into one Has time-slicing method. The transmission signals are preferably transferred via a single transmission channel.

Prinzipiell kann ein solches Übertragungssystem über mindestens zwei logische Ebenen der Kommunikation verfügen, die jeweils unterschiedlichen Anwendungen oder Übertragungsmodalitäten zugeordnet sein können. Entsprechend der Anwendung werden diese Kommunikationsebenen unterschiedliche Prioritäten der Kommunikation besitzen. Weiterhin können auch mehr als zwei Kommunikationsteilnehmer an dem Kommunikationsnetz beteiligt sein, die nicht unbedingt alle über die laufende Kommunikation der übrigen Teilnehmer unterrichtet sind. Findet beispielsweise ein Datenaustausch zwischen zwei Hörgeräten statt, kann eine Fernbedienung aufgrund der begrenzten Reichweite der Hörgeräte eventuell keine Informationen über eine laufende Kommunikation besitzen. Setzt nun eine eventuell zeitkritische Anwendung einer höheren Kommunikationsebene beziehungsweise ein in das Kommunikationssystem nicht kontinuierlich eingebundener Teilnehmer auf Anforderung ein drahtlos zu übermittelndes Signal ab, so kann im Falle einer momentan laufenden Kommunikation diese gestört und die gesendeten Daten sowohl der gestörten Verbindung als auch die der Anwendung höherer Priorität beziehungsweise der externen Quelle verloren gehen. Für das Übertragungssystem besteht hier die Anforderung, dass die Daten der Übertragung höherer Priorität nicht verloren gehen dürfen. Daher werden bei der Kommunikation verschieden lange Datenpakete verwendet. Die Datenpakete höherer Priorität setzen sich durch, wenn die niederprioren Übertragungsanforderungen solange angehalten werden, wie der Übertragungskanal besetzt ist.In principle, such a transmission system can have at least two logical levels of communication, which can each be assigned to different applications or transmission modalities. Depending on the application, these communication levels will have different priorities of communication. Furthermore, more than two communication participants can be involved in the communication network, not necessarily all about the ongoing communication the other participants are informed. For example, if there is a data exchange between two hearing aids, a remote control may not have information about ongoing communication due to the limited range of the hearing aids. If a possibly time-critical application of a higher communication level or a subscriber not continuously integrated in the communication system then places a signal to be transmitted wirelessly on request, it can be disturbed in the case of a currently running communication and the transmitted data of both the disturbed connection and the application higher priority or the external source. For the transmission system, there is a requirement here that the data of the higher priority transmission must not be lost. Therefore, different lengths of data packets are used in the communication. The higher priority data packets assert themselves when the lower priority transmission requests are halted as long as the transmission channel is busy.

Die vorliegenden Ausführungsbeispiele stellen bevorzugte Ausführungsformen der vorliegenden Erfindung dar.The present embodiments represent preferred embodiments of the present invention.

Die Übertragungsebenen beziehungsweise Kommunikationspartner unterschiedlicher Priorität bedienen sich verschiedenartiger Datenpakete. Wird für die Kommunikation in der untersten Ebene ein Grunddatenwort DW angesetzt, so werden diese Datensätze im ungestörten Fall zwischen den Partnern versandt. Tritt nun eine Anwendung / ein Teilnehmer einer höheren Priorität auf, so sollte die laufende Kommunikation unterbrochen und die notwendigen Informationen ausgetauscht werden. Zu diesem Zweck verschickt die Anwendung höherer Priorität Datenpakete, die deutlich länger sind als die der Anwendung niedrigerer Priorität. Bei unkoordiniertem Eintreffen der Worte höherer Priorität wird die laufende Kommunikation zunächst gestört, da der empfangene Kommunikationsteilnehmer die Überlagerung des ursprünglichen und des dazukommenden Sendesignals empfängt. Durch die zeitliche Länge des Sendesignals höherer Priorität kann allerdings nach abgeschlossenem Sendevorgang der niederprioren Verbindung ein Teil des neuen Sendesignals ungestört empfangen werden. Deshalb ist vorzugsweise das Sendesignal des Kommunikationselements höherer Priorität aus einem ersten und einem zweiten Block aufgebaut, wobei der zweite Block die vollständige zu übertragende Information enthält und selbst unter extremen Bedingungen immer nach einer beendigten Übertragung des ersten Blocks empfangen werden kann.The transmission levels or communication partners of different priority use different types of data packets. If a basic data word DW is used for communication in the lowest level, these data records are sent between the partners in the undisturbed case. If an application / participant of a higher priority now appears, the communication in progress should be interrupted and the necessary information exchanged. For this purpose, the higher priority application sends data packets that are significantly longer than those of the lower priority application. In the case of uncoordinated arrival of the words of higher priority, the current communication is initially disturbed because the received communication user receives the superimposition of the original and the incoming transmission signal. Due to the temporal length of the transmission signal of higher priority, however, a part of the new transmission signal can be received undisturbed after completion of the transmission process of the low-priority connection. Therefore, preferably, the transmission signal of the higher-priority communication element is composed of a first and a second block, the second block containing the complete information to be transmitted, and can always be received even under extreme conditions after a completed transmission of the first block.

Je nachdem, ob die Übertragung absolute (z. B. Lautstärkepegel 3) oder relative Befehle (z. B. Erhöhung der Lautstärke um eine Stufe) enthält, kann der erste Teil des Datenpakets entweder aus mindestens einem der zu sendenden Datenworte oder aus einer Aneinanderreihung von Präambeln bestehen. Bei der Übertragung absoluter Daten besteht der Vorteil der Übertragung des Datenworts DW als erster Teil des Datenpakets darin, dass für den Fall fehlerfreier Übertragung die Daten bereits früher erkannt werden können. Eine Übertragung relativer Befehle kann in einem Datenpaket nicht zweimal erfolgen, da bei fehlerfreier Übertragung beispielsweise eine Erhöhung eines Werts sonst zweimal durchgeführt werden würde.Depending on whether the transmission contains absolute (eg volume level 3) or relative commands (eg increasing the volume by one level), the first part of the data packet can either consist of at least one of the data words to be transmitted or of a sequence consist of preambles. at the transmission of absolute data, the advantage of the transmission of the data word DW as the first part of the data packet is that in the case of error-free transmission, the data can be detected earlier. A transmission of relative commands can not be done twice in a data packet, since otherwise an increase in a value would otherwise be carried out twice in the case of error-free transmission.

Werden Folgen von Präambeln vorausgeschickt, enthalten diese Präambeln keine Informationen, sie zeigen dem System lediglich an, dass bald eine Datenübertragung folgen wird. Alle Teilnehmer geringerer Priorität werden während des Empfangs wichtigerer Daten beziehungsweise Präambeln daran gehindert, eine eigene Kommunikation aufzunehmen. Selbst wenn die Übertragung höherer Priorität beendet ist, wird der Übertragungskanal eine gewisse Zeit Tack freigehalten, bevor wieder eine Übertragung auf niederwertiger Ebene erfolgen darf.If sequences of preambles are sent in advance, these preambles do not contain any information, they just indicate to the system that data transmission will soon follow. All lower priority subscribers are prevented from receiving their own communication during the reception of more important data or preambles. Even if the transmission of higher priority is completed, the transmission channel is kept free for a certain time T ack , before again at a low-level transmission may take place.

Wird allgemein eine Übertragung der Priorität N ausgeführt, so haben die Datenpakete eine minimale Länge von {(N+1)DW}. Die Priorität steigt mit wachsender Zahl N. Unter der Annahme höchstens einer Kommunikation innerhalb einer Prioritätsebene kann auf diese Weise die jeweils wichtigste Kommunikation ungestört erfolgen. Besitzen Teilnehmer, die keine Information über die ablaufende Kommunikationen besitzen, eine höhere Priorität, so können sie ihre Daten in das Kommunikationssystem einbringen.In general, when a priority N transmission is performed, the data packets have a minimum length of {(N + 1) DW}. The priority increases with increasing number N. Assuming at most one communication within a priority level, the most important communication can take place undisturbed in this way. If subscribers who have no information about the ongoing communications have a higher priority, they can bring their data into the communication system.

Eine Ausführungsform gemäß der vorliegenden Erfindung lässt sich entsprechend FIG 1 durch ein WIRELESS-System für Hörgeräteanwendungen realisieren. Das System besteht aus zwei Hörgeräten HG1, HG2 und einer Fernbedieneinheit RCU, die miteinander drahtlos kommunizieren. Aufgrund der begrenzten Sendeenergie der Hörgeräte HG1, HG2 sind die Übertragungsreichweiten begrenzt. Die Fernbedienung RCU ist nicht in die Kommunikation der beiden Hörgeräte eingebunden.An embodiment according to the present invention can be accordingly FIG. 1 through a WIRELESS system for hearing aid applications. The system consists of two hearing aids HG1, HG2 and a remote control unit RCU, which communicate wirelessly with each other. Due to the limited transmission energy of the hearing aids HG1, HG2, the transmission ranges are limited. The remote control RCU is not integrated in the communication of the two hearing aids.

Weiterhin gibt es verschiedene Kommunikationsebenen. Die unterste Ebene stellt der binaurale Abgleich der Hörgeräte 1, 2 bezüglich der Signalverarbeitungsalgorithmen dar. Beispielsweise werden hierdurch die zu verwendenden Hörprogramme in beiden Hörgeräten 1, 2 abgeglichen.Furthermore, there are different levels of communication. The lowest level represents the binaural comparison of the hearing aids 1, 2 with respect to the signal processing algorithms. For example, thereby the hearing programs to be used in both hearing aids 1, 2 are adjusted.

Eine Anwendung höherer Priorität ist die Bedienung der manuellen Bedienelemente am Hörgerät durch den Hörgeräteträger. Bei einer Bedienung sollte eine sonstige Kommunikation sofort unterbrochen und der binaurale Abgleich der Bedienelementeeinstellungen durchgeführt werden. Die Übertragung der Einstellwerte erfolgt mit absoluten Werten. Die Datenpakete bestehen demnach aus einer zweifachen Übertragung des ursprünglichen Datenworts.A higher priority application is the operation of the manual controls on the hearing aid by the hearing aid wearer. During an operation, any other communication should be interrupted immediately and the binaural adjustment of the control element settings carried out. The transmission of the setting values is done with absolute values. The data packets therefore consist of a double transmission of the original data word.

Tritt eine Bedienung der Fernbedienung RCU auf, wird die aktuelle Kommunikation wiederum unterbrochen und die gewünschte Fernbedienfunktion umgesetzt, da auch der Bedienung der Fernbedienung RCU sehr hohe Priorität eingeräumt wird. Dabei wird häufig auf relative Befehlssätze zurückgegriffen, wobei dem Datenwort eine Reihe von Präambeln vorangestellt ist.If an operation of the RCU remote control occurs, the current communication is again interrupted and the desired remote control function implemented, since the operation of the RCU remote control is given very high priority. It is often resorted to relative instruction sets, the data word is preceded by a series of preambles.

Die zeitlichen Abläufe der Übertragung ergeben sich wie in FIG 2 bis 6 beschrieben. Zu erkennen ist, dass die Kommunikationen mit jeweils höherer Priorität im Falle eines Kommunikationskonfliktes die Kommunikation geringerer Priorität stören, zu einem Abbruch letzterer führen und ihre eigenen Daten übertragen. Wird beispielsweise gemäß FIG 2 eine Übertragung aufgrund einer manuellen Bedienung angeregt, so werden vom Hörgerät HG1 absolute Datenpakete doppelt an das andere Hörgerät HG2 übermittelt. Damit werden die Nutzdaten in einem ersten Teil und erneut in einem zweiten Teil des Datenpakets übertragen. Den beiden Teilen ist - wie jedem Datenpaket - eine Initialisierungspräambel vorangestellt, die jedoch der Übersicht halber in sämtlichen Figuren nicht dargestellt ist.The temporal processes of the transfer arise as in FIGS. 2 to 6 described. It will be appreciated that in the event of a communication conflict, the higher priority communications will interfere with the lower priority communications, lead to their aborting, and transmit their own data. For example, according to FIG. 2 stimulated transmission due to manual operation, the hearing aid HG1 absolute data packets are transmitted twice to the other hearing aid HG2. Thus, the payload data is transmitted in a first part and again in a second part of the data packet. The two parts - as each data packet - preceded by an initialization preamble, which, however, for the sake of clarity is not shown in all figures.

Tritt innerhalb einer gewissen Zeit Tack eine weitere Bedienung auf, so muss das entsprechende Datenwort nur noch einfach gesendet werden, da andere Kommunikationsteilnehmer niedrigerer Priorität mindestens eine Zeit Tack schweigen, bevor weitere Übertragungen angestoßen werden. Nach dieser Zeit Tack sendet das bediente Gerät dann noch einen endgültigen Synchronisationsbefehl zum binauralen Abgleich, der von dem anderen Teilnehmer HG2 mit einer Quittung beantwortet wird. Auf diese Weise können die Einstellungen, z. B. Lautstärkesteller oder Programmwahl, die am Hörgerät HG1 manuell vorgenommen werden, drahtlos auf das Hörgerät HG2 übertragen werden. Die Bestätigungszeit Tack kann dabei für die beiden Hörgeräte HG1 und HG2 unterschiedlich sein.If another operation occurs within a certain time T ack , the corresponding data word only has to be sent simply because other communication subscribers of lower priority are silent for at least one time T ack before further transmissions are initiated. After this time T ack the operated device then sends a final synchronization command for binaural matching, which is answered by the other party HG2 with an acknowledgment. In this way, the settings, eg. B. volume control or program selection, which are made manually on the hearing aid HG1, wirelessly transmitted to the hearing aid HG2. The confirmation time T ack may be different for the two hearing aids HG1 and HG2.

FIG 3 zeigt ein zeitliches Signalschema für den Fall einer automatischen Synchronisation der Signalverarbeitung. Zunächst sendet das Hörgerät HG1 ein Datenpaket zum Abgleich ab. Daraufhin sendet auch das weitere im Hörgerätesystem befindliche Hörgerät HG2 ein Synchronisationsdatenpaket zum Abgleich ab. Auf diese Weise werden den Hörgeräten wechselseitig diejenigen Einstellwerte übermittelt, die die eigene Signalverarbeitung aufgrund der Umgebungsbedingungen als optimal ermittelt hat. Um jedoch unterschiedliche Hörgeräteeinstellungen aufgrund der unterschiedlichen Lagen der Hörgeräte zu vermeiden, findet ein entsprechender Abgleich statt. FIG. 3 shows a temporal signal scheme in the case of automatic synchronization of the signal processing. First, the hearing aid HG1 sends a data packet for comparison. Thereupon, the further hearing aid HG2 located in the hearing aid system also sends a synchronization data packet for comparison. In this way, mutually those setting values are transmitted to the hearing aids, which has determined its own signal processing due to the environmental conditions as optimal. However, in order to avoid different hearing aid settings due to the different positions of the hearing aids, a corresponding adjustment takes place.

Weiterhin kann die binaurale Information zur Steuerung von Signalverarbeitungsalgorithmen, z. B. einer Störgeräuschunterdrückung, verwendet werden.Furthermore, the binaural information for the control of signal processing algorithms, z. As a noise canceling used.

Setzt, wie in FIG 4 angedeutet ist, ein Sendevorgang der Fernbedienung ein, die durch die begrenzte Reichweite der Hörgerätekommunikation keine Kenntnis über ablaufende Kommunikationsvorgänge hat, so überträgt diese zunächst eine Folge von Präambeln in einem ersten Teil, bevor das eigentliche Nutzdatenwort in einem zweiten Teil des Datenpakets folgt. Den beiden Teilen ist wieder eine nicht dargestellte Initialisierungspräambel vorangestellt. Da die Hörgeräte unmittelbar auf die Fernbedienung reagieren sollen, wird den Datenpaketen der Fernbedienung eine sehr hohe Priorität eingeräumt, was durch die große Länge des ersten von der Fernbedienung gesendeten Datenpakets umgesetzt ist. Nach dieser hochprioren Nachricht sind auch hier die Hörgeräte HG1 und HG2 über eine vorgegebene Zeit am Senden gehindert. Währenddessen können von der Fernbedienung ohne weiteres Kurzdatenpakete, beispielsweise für die Lautstärkeeinstellung und Programmwahl, an die Hörgeräte übertragen werden. Im Anschluss an diese bei den Hörgeräten erzwungene Sendepause erfolgt wiederum ein Abgleich zwischen den Hörgeräten, wie er im Zusammenhang mit FIG 2 bereits beschrieben wurde. Dieser Abgleich stellt sicher, dass auch beide Hörgeräte HG1 und HG2 die Befehle von der Fernbedienung erhalten haben.Places, as in FIG. 4 is indicated, a transmission process of the remote control, which has no knowledge of running communication due to the limited range of hearing aid communication, so this first transmits a sequence of preambles in a first part, before the actual payload follows in a second part of the data packet. The two parts is again an initialization preamble, not shown prefixed. Since the hearing aids are to react directly to the remote control, the data packets of the remote control are given a very high priority, which is implemented by the great length of the first data packet sent by the remote control. After this high-priority message, here too the hearing aids HG1 and HG2 are prevented from transmitting for a predetermined time. Meanwhile, the remote control can easily transmit short data packets, for example for volume adjustment and program selection, to the hearing aids. Following this forced in the hearing aids pause again takes place a comparison between the hearing aids, as in connection with FIG. 2 already described. This adjustment ensures that both hearing aids HG1 and HG2 have received the commands from the remote control.

In FIG 5 ist der Fall dargestellt, dass während der Synchronisation der Signalverarbeitung der beiden Hörgeräte eine manuelle Bedienung stattfindet. Das Hörgerät HG1 sendet in diesem Fall ein übliches Synchronisationsdatenpaket zum Abgleich der Signalverarbeitung ab. Bereits während des Sendens dieses Synchronisationsdatenpakets setzt die manuelle Bedienung am Hörgerät 2 ein, so dass das Hörgerät HG2 ein verlängertes Datenpaket abschickt, um den Synchronisationsvorgang abzubrechen. Die Übermittlung der Einstellwerte durch die manuelle Bedienung am Hörgerät HG2 gewinnt damit höchste Priorität. Das am Ende des Datenpakets übertragene Datenwort kann somit problemlos vom Hörgerät 1 empfangen werden. Nach Ablauf der Zeitdauer Tack findet wiederum ein Bestätigungs- beziehungsweise Synchronisationsvorgang statt, bei dem das den Einstellwert der manuellen Bedienung enthaltende Datenwort nochmals vom Hörgerät 2 abgesandt und anschließend vom Hörgerät 1 quittiert wird. Daran anschließend findet nun der Synchronisationsvorgang der Signalverarbeitung wie in FIG 3 statt.In FIG. 5 the case is shown that takes place during the synchronization of the signal processing of the two hearing aids manual operation. In this case, the hearing aid HG1 transmits a customary synchronization data packet for adjusting the signal processing. Already during the transmission of this synchronization data packet, the manual operation starts on the hearing device 2, so that the hearing aid HG2 sends off an extended data packet in order to interrupt the synchronization process. The transmission of the setting values by the manual operation on the hearing aid HG2 thus gains highest priority. The transmitted at the end of the data packet data word can thus be easily received by the hearing aid 1. After expiration of the time period T ack , a confirmation or synchronization process takes place in which the data word containing the setting value of the manual operation is again sent by the hearing device 2 and subsequently acknowledged by the hearing aid 1. Subsequently, the synchronization process of the signal processing as in FIG. 3 instead of.

In FIG 6 ist wiederum ein Fall dargestellt, bei dem die Synchronisation der Signalverarbeitung durch eine manuelle Bedienung unterbrochen wird. In diesem Fall findet die manuelle Bedienung am Hörgerät HG1 statt und liegt zeitlich hinter dem Synchronisationsdatenpaket des Hörgeräts HG1. Der durch die manuelle Bedienung gewünschte Einstellwert wird auch hier aus Prioritätsgründen doppelt übertragen. Da die manuelle Bedienung beziehungsweise die diesbezügliche Übertragung des gewünschten Einstellwerts erst nach dem Synchronisationsdatenpaket einsetzt, beginnt das Hörgerät HG2 noch mit einem eigenen Synchronisationsdatenpaket darauf zu antworten. Die beiden Sendevorgänge überschneiden sich in diesem Fall so, dass auch das zweite Datenwort zur Übermittlung des Einstellwerts der manuellen Bedienung, das vom Hörgerät HG1 abgesendet wird, durch den Sendevorgang des Hörgeräts HG2 teilweise überlagert wird. Beide Datenwörter können vom Hörgerät HG2 nicht fehlerfrei empfangen werden. Da jedoch wie üblich nach einer gewissen Zeit ein Abgleich der eingestellten Hörgeräteparameter durchgeführt wird, bei dem das Hörgerät HG1 den Einstellwert erneut sendet, wird dem Hörgerät HG2 nun die Möglichkeit gegeben, das Datenpaket komplett zu empfangen. Das Hörgerät HG2 quittiert diesen Empfang entsprechend. Da die Synchronisation der Signalverarbeitung auch hier nicht vollzogen werden konnte, findet sie nach dem Abgleich der Hörgeräteparameter in üblicher Weise statt.In FIG. 6 again a case is shown, in which the synchronization of the signal processing by a manual operation is interrupted. In this case, manual operation takes place on the hearing aid HG1 and lies behind the synchronization data packet of the hearing aid HG1 in terms of time. The setting value desired by the manual operation is also twice transmitted here for reasons of priority. Since the manual operation or the relevant transmission of the desired setting value begins only after the synchronization data packet, the hearing aid HG2 begins to respond with its own synchronization data packet. The two transmissions overlap in this case so that the second data word for transmitting the setting value of the manual operation, which is sent by the hearing aid HG1, is partially superimposed by the transmission process of the hearing aid HG2. Both data words can not be received correctly by the hearing aid HG2. However, since, as usual, a comparison of the set hearing device parameters is performed after a certain time, in which the hearing aid HG1 sends the set value again, the hearing aid HG2 is now given the opportunity to receive the data packet completely. The hearing aid HG2 acknowledges this reception accordingly. Since the synchronization of the signal processing could not be completed here, it takes place after the adjustment of the hearing aid parameters in the usual way.
