Description
TRANSCEIVER FOR VARIOUS INFORMATION FORMATS
This invention relates to an apparatus for reproducing messages of different formats transmitted over a communications network and for sending messages of different formats over a communications network. In particular, the invention relates to an apparatus for reproducing messages coming from, and for sending messages over, the Internet or the World Wide Web (WWW) or the integrated services digital network (ISDN).
Computer-telephone-integration (CTI) applications, i.e., PC-assisted telephony, are known in the art.
Systems capable of turning a PC into a telephone look as follows, for example:
The PC is connected to a telephone via the V.24 interface. From the telephone, or rather from the So bus, a connection is established to an ISDN
communications system. The latter, in turn, connects the PC and the telephone to the public network.
Another possibility is to connect the PC directly to the public network via an ISDN card and the So bus.
To implement the telephone function in the PC, a telephone is connected to the a/b interface. A
This invention relates to an apparatus for reproducing messages of different formats transmitted over a communications network and for sending messages of different formats over a communications network. In particular, the invention relates to an apparatus for reproducing messages coming from, and for sending messages over, the Internet or the World Wide Web (WWW) or the integrated services digital network (ISDN).
Computer-telephone-integration (CTI) applications, i.e., PC-assisted telephony, are known in the art.
Systems capable of turning a PC into a telephone look as follows, for example:
The PC is connected to a telephone via the V.24 interface. From the telephone, or rather from the So bus, a connection is established to an ISDN
communications system. The latter, in turn, connects the PC and the telephone to the public network.
Another possibility is to connect the PC directly to the public network via an ISDN card and the So bus.
To implement the telephone function in the PC, a telephone is connected to the a/b interface. A
headphone and a microphone are provided for listening to messages via the PC and for entering voice messages into the PC. The basis for such an integration is the Telephony Application Programming Interface (TAPI), a uniform interface for telecommunications programs.
Under TAPI, applications can cooperate with arbitrary hardware, such as modems, ISDN cards, or private branch exchanges. For the telephone technology, too, a wide variety of offers is available. This includes analog telephone technology as well as ISDN or ATM.
Accordingly, TAPI represents a uniform programming interface which provides a uniform user interface independently of the communications hardware and the method of transmission, such as ISDN or GSM.
Furthermore, TAPI permits mixed transmission of data and speech and incorporates a fax/data/phone mode switch for differentiating incoming calls.
This so-called Internet telephony, which permits connections to be established at low cost, but with a.
relatively low quality, will in future be equipped with so-called voice gateways. Then, the called party will no longer need an Internet connection for his PC
(from: "Der PC als Telefon", "Funkschau 12/96", pages 24 - 31).
Further prior-art solutions describe how a personal computer can be converted into an added-feature telephone.~The reasons for the use of CTI are as follows.
Through the use of computer-assisted telephony, the customer can be offered improved services. In such an application, a personal computer, referred to herein as "PC", is converted into an added-feature telephone through the use of particular interfaces and software (from: "Der Personal-Computer als Komforttelefon", "Funkschau 14/96", pages 74 - 81).
The above-described prior-art solutions use particular interfaces and software for converting a PC into an added-feature telephone. Prerequisites for this are that both a PC with a certain capacity and an interface to a telephone network are present. Such a solution offers a great number of service features and is user-friendly, but requires considerable space for the installation of a PC. It is not possible to move around during "telephoning", and in order to simply receive a message, a program must be started, which requires certain basic knowledge. In professional applications in an office environment, such a PC in combination with an added-feature telephone facilitates work, but at home, this is rather impractical.
The invention has for its object to provide a terminal which enables a user in his private environment to receive and transmit messages of different formats.
According to the invention, this object is attained by the teaching of claim 1.
One advantage of the invention is that the user of such an apparatus can both receive and transmit messages of different formats. By "messages of different formats", a message from the Internet, e.g., an E-mail, and a voice message is understood, for example. The user can thus change in an advantageous manner between text messages and voice messages, which he can review in any form desired by him. Another advantage is that for such an application, no PC need be installed, and no complex software need be started on the PC to make a telephone call. Nevertheless, a similar function can be implemented with such an apparatus in a simple manner.
Further advantageous aspects of the invention are defined in the subclaims.
A particular advantage arises from subclaim 3, according to which the transmitted voice messages or the transmitted text messages are stored in associated memories, so that they can be reviewed at a later time or be converted to a different format. This increases the flexibility of the system in an advantageous manner.
The invention will now be explained in greater detail with reference to the accompanying drawing, whose single figure is a block diagram of the apparatus in accordance with the invention.
An apparatus TER for reproducing messages of different formats transmitted over a communications network NN
comprises an interface S for interfacing the apparatus TER to the communications network NN. The communications network NN is, for example, the integrated services digital network (ISDN). The interface S is connected, for example by a telephone wire 3, to a further interface circuit 4, which contains a modem, for example. The apparatus TER
further includes a circuit 5 which serves to supply power to the interface S. This may be a simple battery, for example. The interface S and the interface circuit 4 provide the connection between the communications network NN and a microcontroller ~cC.
The microcontroller ~C contains a read-only memory.
Connected to the microcontroller are further, nonvolatile memory devices MEM1, MEM2, for example EPROMs or flash EPROMs.
The interface circuit 4 for adapting messages of the communications network to the microcontroller ~C will hereinafter be referred to as "modem". This modem serves mainly to connect the apparatus TER to the Internet or to the World Wide Web. This means that the modem is capable of handling different bit rates, e.g., 28,000 b/s. The modem may also take the form of a digital interface of the ISDN type.
The apparatus TER for reproducing transmitted messages of different formats further includes a device NET for adapting the transmitted messages of different formats to the apparatus.
Furthermore, the apparatus TER comprises a voice recognition unit REC for recognizing a voice message.
Associated with the voice recognition unit REC is a unit for converting the voice message to text. The apparatus TER further includes a text-to-speech unit SYN. A loudspeaker L is provided for outputting the speech, and a monitor MON is provided for displaying the text.
Under TAPI, applications can cooperate with arbitrary hardware, such as modems, ISDN cards, or private branch exchanges. For the telephone technology, too, a wide variety of offers is available. This includes analog telephone technology as well as ISDN or ATM.
Accordingly, TAPI represents a uniform programming interface which provides a uniform user interface independently of the communications hardware and the method of transmission, such as ISDN or GSM.
Furthermore, TAPI permits mixed transmission of data and speech and incorporates a fax/data/phone mode switch for differentiating incoming calls.
