The system may be designed to avoid leaving the microphone switched on. The radio transmitter for the microphone may send low-frequency signals to control TV cameras etc.

Description

Device composed of a microphone Wireless and a receiver.

The invention relates to a device Composed of a wireless microphone and a receiver.

Such devices are already known and are being using. The receiver comprises a low frequency output, which, on the one hand it emits the emission tone (program tone) while The wireless microphone is switched to broadcast, and on the other hand allows consultations with the realization while the microphone Wireless is not switched to broadcast.

Because the microphone noises wireless are constantly present in the realization, the Surrounding noises disturb the realization staff.

EP 0 806 758 A1 describes a wireless accompaniment device. It comprises a device cover for tone and text transmission of accompaniment to at least one television receiver and one receiver Radio wirelessly. The cover is housed on the cover of a microphone and comprises a program memory to store a program and data; a microprocessor to control all the device according to the program and the data read from the program memory; an image memory to store data of image and text data; an LCD screen to indicate states of selection and reservation of a song; a tone memory for store accompaniment tone data; a source circuit of tone to process the accompaniment tone data according with a desired song and read from the tone memory to generate an accompaniment tone signal; a video processor for transform image and text data, which correspond to the desired song and that are read from the image memory, in a television signal; and transmission means, which comprise the minus a first transmission medium to mix the signal of television broadcast by the video processor and a tone signal from voices provided by a microphone, to thus emit a wirelessly mixed signal to the television receiver and a second transmission medium to mix the tone signal of accompaniment, which has been issued by the source circuit of tone, and the voice tone signal that has been made available by the microphone, to emit a mixing signal of Wirelessly to the radio receiver.

It is the objective of the present invention to avoid this disadvantage.

This goal is solved because the microphone It contains a remote action function in the form of a switching or connection device, the receiver contains a electrical switch and the switch performs an assignment of Adjustable signal of the audio signal transmitted at low outputs frequency integrated into the receiver, and makes the signal available switching for further evaluation, such as for the remote control of devices, and the low frequency outputs, With the switching or connection function, they can be switched from alternate, parallel, active and inactive form.

A low frequency output is intended for program tone or broadcast tone, while the others Low frequency outputs are provided for inquiries with the realization. Since the switching or connection function it can make the contact with the realization short, in fact, only when a consultation is required, they are not constantly present the noise of the microphone environment in the realization. From  This mode does not continue to bother the realization staff.

Preferably, the switching function or connection is controlled by a push button, a switch or a device additional electric.

Many technical developments have simplified the TV staff work in recent years. Presents itself a new generation of wireless manual microphones that they have an intercom function, and thus, They solve known problems.

Sports events have evolved in recent years to mass events and are transmitted with the corresponding complexity on television. Camera shots and unusual interview positions are just as popular as conference connections between various sporting events. Therefore, perfect communication is indispensable and expensive digital intercom matrix systems with digital intercom sites can no longer be dispensed with. The systems of Riedel, IBT or
Drake

The keys of intercom sites digital can be used with different communication targets of so that communication can also occur in parallel Directed between different people. In situations of great activity you can talk to several people at the same time or you they can group groups of people by forming groups or conferences.

You cannot equip all people in one production with an intercom site. Therefore, it also employ wireless systems that communicate production managers or set technicians with the accomplishments. Communication without However, it is particularly important for actors in front of the camera. The indications of the writing and the realization provide reporters and moderators with the most information current or program development modifications. Too the program tone is an important guidance aid to capture the comments of the previous speaker or take as reference a introductory moderation Therefore, almost all moderators They work with a wireless receiver. You can talk to moderators individually using programmed keys and They can also be contacted during moderation. Only the possibility of reply of the protagonists is limited. Yes all other participants have sites of intercom or at least wireless radio systems with communication key, the actors use their microphones to answer the completion or the wording. Obviously this communication does not occur during moderation, but often they have to elaborate and clarify many aspects just before or After the red light. The selection of the companions of the interview must be prepared as well as the selection of scenes that have to be introduced, and often the same They can only be determined on short notice.

Therefore, the microphone signals are enter the intercom independently of the regulator to be able to listen to them in the corresponding positions, such as the realization or the editor of the broadcast, permanently. Yes Several reporters participate in the broadcast, obviously the Communication has to be available to everyone. With large transmissions, therefore, enter 4 and more signals from microphones at an intercom site. The disadvantage of this permanent switching is the fact that by microphones the surrounding noises are also constantly transmitted. Whether take into account football matches or broadcasts at this point of ice hockey with a large audience, surely you can understand that the "background sound" in the headphones of the Intercom sites are considered annoying in the long term. Is even more problematic when the orders are not understandable because they are superimposed by a crowd of fans Screaming.

Until now there was no function of switching with which the connection of the  microphones temporarily. A communication at the moment in the that is required provides silence and guarantees that no one has to adjust the volume of the microphone signals in the intercom sites so that other orders do not disappear by the noise of the microphone signals.

A product innovation from Wisycom represents An important step in solving this problem. He wireless manufacturer is internationally known and specializes in HF technique with practical guidance. In the new generation of wireless microphones a push button was integrated pressure that triggers a switching or connection in the receiver. The receiver unit is equipped with two outputs of audio that are switched alternately depending on the pressure of the key. The first output makes the signal available in the state resting and joins the input of the audio mixing table. The second output is only switched with key pressure and You can connect directly to the intercom. If the reporter wants talk to the intercom, press the button and the audio signal it is switched from output 1 to output 2. The first output is silenced for the duration of the key press. Whether release the button again, the second output (intercom) is silenced and the signal is presented again by the first Mixing table outlet. The disturbing secondary noises they are only transmitted during the conversation and are no longer present permanently by switching. This way you guarantees that orders are not accidentally issued through the channel broadcast because the microphone was already open for Next moderation.

Apart from the silence that encourages concentration There is an additional advantage of the intercom. The call signaling of the communication keys on the panel of the intercom with a pending entry so far no could use for permanent signals introduced in a way external The signal control of external signals is performs on all intercom manufacturers using a threshold value switching. If a certain level is exceeded signal, a light function is activated on the key correspondent. The aforementioned then knows immediately who wants Talk to him and where he can answer. However, yes, as in the case described above, noise from the environment, never get off this level. With the result that the key lights up permanently, even if you are not speaking by the microphone

Only for the use of the output switched signaling is reasonably used again. He intercom threshold value passes permanently through below the threshold by the second output of the silenced receiver. Only the connected audio, triggered by the pressure of the key on the hand transmitter, exceeds the threshold value and activates the signaling. Until now the actors had to be recognized due to lack of voice signaling, however, now, the flashing of the key shows who has spoken and why key can be answered.

In addition, the switching function opens even other apps.

The communication between the realization of program and external posts for, for example, emissions from news or elections is usually done by unions of 4-wire communication Hybrid phones are often used, GSM interfaces or ISDN encoder-decoder. Technical and content agreements are made through these connections between the realization of the program and the local. For the ones reporters or moderators can follow in front of the camera the broadcast that is being transmitted, often a additional N-1 connection. The local mobile unit Switch the signal to a receiver and using a headset (ear-plug), actors can also listen and the realization of the program can speak to you by N-1 If a reporter wants to contact the realization of the program, you can speak through your manual microphone by the broadcast connection. However, for this you have to be Open the potentiometer, the emission connection has to be available, the connection has to be made until completion and You have to listen to it. Alternatively, the technician local can speak to the realization by connecting 4 wires and Relay the desired news.

Now, with the intercom function, the Switched receiver output can be added to the 4 connection threads. The reporter can thus communicate in a way independent of the key pressure emission connection with the Program realization. The way of answering the realization of the program is now available in the form of N-1

Function description

A switching device in the unit reception is controlled by remote control by a microphone Wireless by a push button. The switching device switches the audio signal transmitted so that the main output of the receiver, during pressing the key on the hand transmitter, Silence and instead, the audio signal is output by the output now active, switched. In the audio stream itself from the Manual sender at the reception site does not change anything during the switching processes As a trigger for switching the interruption of a digital sign, which is permanently transmitted from the manual microphone to the reception post. Lack of sign triggers an electrical deviation of the signal from the receiver audio already demodulated to the switched output that has already been mentioned previously. The transmission of the switching signal does not require additional bandwidth Reference is made below to the main output with state 1 and to "switching output" with state 2.

Purpose

Variable switching of the audio signal transmitted serves for the different subsequent evaluation of the signal in certain situations of use (production, emission, transmission). In state 1, the transmitted audio signal is used corresponding to the previous use of systems of wireless microphone At the time of state 2 you can use the signal for later applications, which only allow one temporary signal switching, such as communication.

For subsequent state-dependent use, the signal is made available by two independent outputs, which they mute alternately.

Application Examples

Technology offers the protagonists of the possibility of triggering a switching function themselves by its manual microphone. It performs, depending on the switching, a mute, a connection or a switching of its microphone signal, which can be distributed by the two outputs separated in two independent positions from each other. The following examples explain the role of technology for applications in television and radio productions and are exemplary for uses additional:

-

A interview reporter before, after and during the intermission of a soccer match selected players. During your interview, Your signal has to be broadcast live or it has to be recorded. This corresponds to state 1 described above. During the party have to make drafting agreements with the alderman or with a writing partner. To do this, the signal is It has to be audible by intercom sites. Without However, they only have to reproduce the signal from the microphone during the communication phase. That is, in this moment state 2 is presented, the reporter can perform a switching that depends on the requirements of your microphone at intercom.

-

A reporter reports on an election and is in place with a local mobile unit The main embodiment is housed in a center Central emission For an N-1 auxiliary connection (phone), the reporter can hear the real-time signal of the central emission realization, whereby the principal governor in the central realization can also speak to you by pressure of a key. However, the reporter cannot answer the councilor of direct form The classic signal path leads the signal only to the audio mixing table. A possibility of communication with the main realization, as a rule, is only  available for mobile unit equipment. By a so-called 4-wire connection maintains a communication link between the Main realization and mobile unit. These communications are made by phone, GSM or ISDN connections, which connect to the adaptation to the present technique with corresponding hybrids. Due to the low costs, communications are maintained during All the way out. The permanent connection of the reporter's microphone with the 4-wire connection, however, it cannot be performed due to to the secondary noises. Too much noise in the central realization would significantly disturb the operation. A temporary connection controlled by the reporter, however, can be achieved with the state 2. The signal of the switched output is added to the communication 4-wire present and thus enables communication Direct with the main realization. A quick reply from reporter to a question of the councilman simplifies considerably Development and avoid misinterpretations. Modifications in the short term they can be agreed and clarified in this way Safe with all participants.

       \ newpage
    

One of the main objectives of the technology is an optimization of developments, and avoid misunderstandings and wrong drives. The best communication possible considerably improves the agreements of those responsible, so that in the future you can avoid unforeseen events that were directly associated with the prior art.
