According to a particularly preferred embodiment of the present invention the completed, virtual order form from a client computer via a unidirectional connection to the server computer or the network control system  Posted. According to a first variant, in the event that the analog TV signal with the saddled DBC signal over a broadband network with back channel was transmitted, the transmitting device of the client computer completed the Send virtual order form via the return channel. According to another variant the completed, virtual order form can be sent as an email over the Internet become.

A particular advantage of the unidirectional transmission of the completed, virtual The order form is now a unidirectional connection is sufficient and no more data from a host computer to that corresponding client computers need to be sent, like this at common ordering processes on the Internet is common. One is in particular Transfer from the host or server computer or network control center to the Client computer not required, since all data content is already with the DBC Signal to the client computer. Thus the user of the client Computers provide the relevant information, preferably in HTML format transferred due to the support of a suitable software Program, d. H. in the present case an HTML browser, in the same way as if it had he established a common network connection. In other words, it stays for completely transparent to the user that the content displayed by means of a television or Radio signal was broadcast and is not real Internet content.

According to a particular aspect of the present invention, each client Computers have a storage device in which the virtual order form as well a software program is stored, the software program for creating, Displaying and completing the virtual order form is suitable as well Send the completed, virtual order form. The order is placed a corresponding product and / or service only with the help of data that was or is contained in the DBC signals or that were already resident in the client computer. That completed Virtual order form is sent in the form of a few data packets, so that the corresponding host computer or the network control center itself when receiving several hundred thousand quasi-simultaneous orders is only minimally charged.  

In particular, these data packets are prepared so that they are from Network control center or from the server computer in a simple way can be processed further.

Further preferred embodiments of the present invention are based on the following figures explained in more detail. The figures contain:

Fig. 5 is an illustration of a DBC order form for control purposes;

Fig. 6 is a flowchart illustrating an example process when filling a DBC order form; and

Fig. 7 is a flow diagram illustrating an exemplary flow of a DBC ordering process.

Fig. 1 shows a block diagram to illustrate a DBC commerce system by saddled by means of DBC a digital signal, the DBC signal, onto an analog television signal and via the vertical blanking intervals or any lines of the TV picture with the television signal from a broadcast center 3 is sent to a receiver 6 via a TV transmitter 4 .

Represented according to a preferred embodiment of the present invention this DBC signal is a full-time music program or video program that is to listeners from conventional as well as listeners from Internet Radio stations aimed, the digital signal from compressed music, preferably in MP3 format, in connection with simultaneously synchronized websites and HTML Content is built up.

To generate the DBC signal, the compressed music and data, preferably in MP3 format, are generated by one or more producers of pieces of music using at least one server computer 1 and sent to a network control system 2 . The network control system 2 preferably represents a provider of the full-time music program. The DBC signal is generated in the network control center 2 , in which the music compressed in MP3 format represents a corresponding program and the HTML content or files, which are transmitted together with this music program and are displayed in an external browser window , provide the listener with additional information, for example with regard to the piece of music being played, the artist or the other music program of the provider.

The created DBC signal is sent from the network control center 2 to the transmission center 3 , where it is saddled onto an analog television signal and is preferably made available via the vertical blanking interval by means of the TV transmitter 4 .

According to a preferred embodiment of the present invention, the Transmission of the analog television signal and the DBC signal via analog State of the art television: According to a further variant, the Broadcast via satellite television.

The receiver 6 must therefore have a receiving device 7 for receiving the DBC signal, which is preferably designed as a cable connection in connection with a so-called TV tuner card. Providers of commercially available TV tuner cards are, for example, Hauppauge! ® with the tuner card Win-TV or WinTV (BT848 chipset), Guillemot with the tuner card Maxi-TV-Video PCI 2, Pinnacle Systems with the tuner card Studio PCTV Rave, Terratec® with the tuner cards TerraTValue, TerraTV + or TerraTV Radio +, Typhoon with the tuner card Silver Crest, Lifeview with the tuner card Fly Video II or VOBIS with the tuner card Highscreen TV Card.

Furthermore, in connection with the receiving device 7, a receiving software program is required in a client computer 8 , which filters the DBC signal transmitted in the blanking interval of the analog television signal or in any lines of the TV picture and, for example, by means of an integrated player which plays MP3 music pieces coded preferably with 128 Kbit / s in real time, while the HTML content contained in the DBC signal is displayed in an external web browser window. By means of this HTML content, the receiver 6 receives information about the piece of music currently being played, the receiver 6 being able to order from the provider, for example a music CD from which the piece of music being played at the same time is taken. For this purpose, the receiver 6 uses a client computer 8 to create an order form, the DBC order form, which the receiver 6 sends from the client computer 8 via a data transmission link 10 to the network control center 2 by means of a transmission device 9 .

To create the DBC order form, the recipient 6 can preferably use a link to call up a software program stored in a memory device of the client computer 8 to order via the HTML content shown in the external web browser window. When this software program is executed, data content is read from the received DBC signal and linked to the DBC order form to be created. This read content is both order data relating to the provider and order data relating to the music CD to be ordered. After the DBC order form has been correctly created, corresponding data are sent unidirectionally to the network control center 2 by means of the transmission device 9 .

In accordance with a preferred embodiment of the present invention, an Internet connection is set up for the transmission of the corresponding data. The connection is usually established via an analog telephone network using the TCP-IP protocol. Furthermore, the data transmission link 10 can also be designed as a digital telephone network, preferably as an ISDN network. According to a further variant, the data transmission can take place via a Datex-P (Data Exchange Packetswitched) network, in which data packets are used, the data which are sent by a large number of client computers 8 being transmitted simultaneously and separately over the network transmitted or via satellite using Datex-S.

Finally, according to a further variant, the transfer of the corresponding data via a cable of the cable or satellite television, for example using a return channel, or via a common one Power line done.

According to a further preferred embodiment of the present invention the so-called ATM (Asynchronous Transfer Mode) as the transmission protocol - Protocol is used in which data is transmitted in packets of equal size divided and transmitted asynchronously, d. that is, the data from the server to Receivers are transmitted faster than vice versa.

In particular, the so-called xDSL (x Digital Subscriber Line) technology can be applied which is one way represents the Internet at 1.5 million bits per second over ordinary To operate copper lines, for example of the analog telephone network. This xDSL technology can currently be divided into ADSL, DSL lite, full-rate ADSL, HDSL, SDSL, T-DSL, Universal ADSL and VDSL. With ADSL (Asymmetric Digital Subscriber Line) is the copper wire of a conventional telephone line in one analog telephone network divided into three different sized areas, one of which two are used for data transport and one for telephoning and where Both forward and return channels each transport different amounts of data can. DSL lite is a slower ADSL for longer distances, while full Rate ADSL represents an ADSL variant that has transmission rates in both directions of up to 8 Mbit / s possible. HDSL (High Date Rate Digital Subscriber Line)  enables fast coupling of local networks and transmissions ordinary copper lines using special HDSL modems, in both Data transfer rates of up to 2 Mbit / s are made possible of particular interest to large companies such as banks or insurance companies is. SDSL (Single Line Digital Subscriber Line) only takes place on a single line and otherwise corresponds to HDSL technology. T-DSL (Telekom Digital Subscriber Line) represents the ADSL connection technology developed by Deutsche Telekom AG is marketed. Universal ADSL enables in the so-called downstream Transmission rates of up to 1.5 Mbit / s and is currently predominantly in the United States used. VDSL (Very High Date Rate Digital Subscriber Line) enables high Transfer rates, d. H. Transfer rates of more than 50 Mbit / s if between Network node and terminal is a very short distance.

As mentioned above, the transmission in the return channel is preferably unidirectional, d. H. from the client computer to the network control center. Especially the The particularly preferred implementation via an Internet connection is the special one Advantage of the present invention in that no data from a host server must be sent to the client computer, but that a unidirectional Connection is sufficient. With normal ordering processes on the Internet, a host Computer first send data to a client computer so that an indication of the corresponding order form or the entire homepage on the client computer is made possible. With a large number of customers, such a solution the host computer is heavily loaded, so either only a few customers quasi can be operated simultaneously or expensive hardware on the host side Computer is required.

The present invention is based on the finding that a transmission from Host computer or network control center is not required to the client computer is because all data content is already transmitted via radio or cable using the DBC signal transferred to the client computer. The user of the client computer sees that corresponding content due to the HTML format and due to the support through a browser in the same way as if it had a normal network connection built up. In other words, it remains completely transparent to the user that the  Content that he sees is not real Internet content at all, but content that was broadcast by means of a television or radio signal. Starting from this Situation, the present invention is based on the knowledge that it is then is no longer necessary to the host computer or the network control center load HTML data to the client computer to build an order form send the client computer individually. Instead, the order is placed only with the help of data that was contained in the DBC signals or that were already resident in the client computer. This will make the host computer or the network control center itself when receiving several hundred thousand quasi-simultaneous orders minimally burdened because the corresponding order data consist of a few data packets from the different client computers be sent. The data packets representing an order are included already prepared so that it can be easily accessed from the network control center can be further processed, as described in detail below.

Fig. 2 shows a block diagram of a DBC-commerce system according to another preferred embodiment of the present invention, in the digital broadcast data from a radio transmitter 11 over a link 12, for example the antenna or satellite, are sent to a receiver 6. The receiver 6 receives the digital radio data by means of an antenna 13 and a transmitting and receiving device 14 .

In this embodiment, the digital radio data represents a full-time Music program consisting of compressed music, preferably in MP3 format, in Connection to synchronized websites and HTML content is established.

From the received radio data, data representing the compressed music are filtered by means of a software program stored in a memory device of a client computer 8 , and preferably played back in real time by means of an integrated player. Here again, as already described with reference to FIG. 1, a music CD can be ordered, for example. For this purpose, an order form is created to order the corresponding music CD, with data representing this order form preferably being sent by means of a mobile radio transmission device 14 via suitable transmission links 15 to a mobile radio center 16 , where the received data is evaluated and the order is processed.

According to a particular embodiment of the present invention, the transmitting and receiving device 14 can be designed as a mobile phone, the corresponding order form being able to be created in the WML (Wireless Markup Language) and using the WAP (Wireless Application Protocol) protocol by means of mobile radio to the mobile radio center 16 can be sent.

FIG. 3 shows an illustration of a computer screen 17 on which HTML content is displayed in a DBC browser window 18 , which are transmitted together with compressed music and serve to provide the receiver with additional information on the piece of music that is being played simultaneously in real time to give. The DBC browser window 18 is preferably a common Internet browser, such as Internet Explorer® from Microsoft® or Navigator® from Netscape®.

In a frame 19 , according to a preferred embodiment of the present invention, an image of a corresponding music CD from which the piece of music being played originates is shown. In a further frame 20 , the further music program of a corresponding provider is preferably shown, and in frame 21 , the recipient is offered interesting HTML links in connection with the piece of music being played. Furthermore, the receiver can record the piece of music being played, for which purpose he preferably positions a position arrow 23 with the computer mouse on a control field 22 and clicks this control field 22 by pressing the left mouse button in order to activate a recording function.

In the event that the recipient wishes to order the corresponding music CD, he can position the position arrow 23 on the frame 19 and, preferably by double-clicking with the left mouse button, a DBC ordering software program for ordering the corresponding music CD call.

FIG. 4 shows a DBC order form 24 which is displayed on the computer screen 17 according to FIG. 3 when the DBC order software program has been called up by means of a double mouse click of the left mouse button.

The DBC order software program reads data relating to a music CD to be ordered, including the title of the music CD 25 , from a received DBC signal. Furthermore, data relating to the provider are read out of the DBC signal in order to enable a client computer to establish a connection with a corresponding device in a network control system. However, this is done in a transparent manner for the recipient so that this data is not shown in the DBC order form.

The recipient can specify the number of music CDs to be ordered in a field 26 , a default number, in this case 1, preferably being specified.

The recipient can enter the desired delivery address in a section 27 of the DBC order form, for which purpose various input fields such as "name", "first name" and "address" are provided. The recipient can choose between "new" and "resident". The selection is made by clicking one of the two selection control fields 28 or 29 . In the event that the recipient selects "new" by clicking on the control field 28 , he is enabled to enter information regarding a new delivery address. In this case, the recipient can enter a delivery address which, for example, does not correspond to his private address, but rather can represent the address of another person, for example the gift of the ordered music CD. In the event that the customer selects "resident" by clicking the control field 29 with the mouse, so-called resident data are read from a memory device of the client computer, which preferably represent the customer's private address, which is generally used as the delivery address.

In a section 30 of the DBC order form 24 , the recipient enters information regarding his bank details, for which purpose various input fields such as "account holder", "bank" or "credit card" are provided.

Here he can click on one of two selection control fields 31 or 32 again and thus choose between "new" and "resident". In the event that the recipient makes the selection "new" by clicking the control field 31 with the mouse, new information is entered regarding the recipient's bank details. In the event that the customer clicks the selection control field 32 with the mouse and thus selects “resident”, resident data are read out from the storage device of the client computer, which preferably represent information relating to the bank details of the recipient. In particular, the resident data represent the bank details of the recipient, who usually uses the client computer.

In the event that the selection control field 29 and / or the selection control field 32 has been clicked and thus the resident data is read out, the corresponding delivery address and / or the corresponding bank details are displayed directly in the DBC order form 24 . The recipient can now finish filling out the DBC order form 24 by initiating the “OK” field 33 , preferably by clicking with the mouse, in order to initiate an order process, or by actuating the “delete” field 34 the DBC created. Delete order form 24 and the information entered therein.

In particular, the selection control fields 28 , 29 , 31 , 32 can be specified with default settings. In the present example, a selection of the control fields 28 and 31 is indicated.

A particular advantage of the present embodiment is that the receiver of MP3-encoded music in a DBC signal is enabled to order one or more music CDs using the DBC order form 24 , with minimal effort being required to fill out the form in the event that only resident data is requested. In particular, the present embodiment offers the advantage that the recipient can enter a delivery address that does not correspond to his own address, so that the ordered music CD (s) can, for example, be sent directly as a gift. Furthermore, various recipients can place orders and pay for the music CD (s) ordered using their own bank details. To prevent an unauthorized user of the client computer from placing orders with the resident data representing the bank details of a recipient who usually uses the client computer, the selection control field 32 and thus that in the client can preferably be selected -Computer stored resident data to be password protected. In particular, several bank details can thus also be stored in the form of different resident data, each of which can be selected by a specific recipient or user of the client computer and are each password-protected.

According to a further preferred embodiment of the present invention, not only order data relating to the address of a provider and the music CD to be ordered are read out from a received DBC signal, but also information relating to encryption codes for encrypting the DBC order form 24 to be sent thus guaranteeing security when ordering via electronic media. In particular, these encryption codes can change at regular intervals and each only have a certain period of validity, which would further increase the security of an order.

FIG. 5 shows a DBC order form for control purposes 35 , in which the data entered in a DBC order form 24 according to FIG. 4 are mapped for checking. This enables a recipient to finally verify the data he has provided before initiating an order process. An order process is initiated by actuating the “order” control field 36 , preferably by clicking with the left mouse button. As a result, data representing the DBC order form is sent from the client computer to a provider via electronic media as described in relation to FIG. 1.

In the event that the recipient or customer decides differently and wants to cancel the ordering process, he can preferably click the "Cancel" control field 37 with the left mouse button and thus cancel the ordering process. This closes the DBC order form for control purposes 35 and the order process is canceled.

FIG. 6 shows a flowchart to illustrate an exemplary sequence when filling out a DBC order form 24 according to FIG. 4.

In the event that the frame 19 in FIG. 3 is clicked with the mouse to order a music CD, a local software program for ordering the corresponding music CD is called in step 38 in a client computer. In step 39 , the execution of this software program begins with querying CD-specific order data and provider-specific data from the order data 40 contained in the DBC signal. While the CD-specific order data is used for display in a DBC order form 24 according to FIG. 4, the provider-specific data are not displayed but only used to establish a connection with a corresponding provider if the completed DBC order form is used by a client -Computer to be sent to a corresponding device in a network control system.

In step 41 , the DBC order form is displayed with default settings containing the CD-specific order data requested. In addition, any integer variable M is set to zero.

In step 42 , the number 1 is added to this integer variable M and a selection N is determined. According to a preferred embodiment of the present invention, the determination of a selection N in the case that M = 0 means that in a DBC Order form 24 according to FIG. 4 is checked whether one of the selection control fields 28 or 29 was clicked with the mouse. In the event that the default setting "new", ie selection control field 28 is activated and a recipient, for example, enters data relating to a delivery address in a field provided for entering a name in section 27 of DBC order form 24 according to FIG. 4 , the selection N is determined to be "new". According to step 45 , data is thus entered into the corresponding fields of area 27 of FIG. 4. The data on which the DBC order form is based are updated immediately in relation to the new data entered in step 45 , and a corresponding, updated DBC Order form is displayed.

In the event that the control selection field 29 of the DBC order form according to FIG. 4 is clicked with the mouse, the selection N is determined to be “resident” and in step 43 corresponding resident data representing a delivery address and in are queried a storage device of the client computer are stored. In this case too, the data on which the DBC order form is based are updated accordingly and the corresponding, updated DBC order form is displayed in accordance with step 46 .

The value M is checked after step 46. In the event that M = 1, step 42 is carried out again. According to a preferred embodiment of the present invention, the determination of a selection N in the event that M = 1 means that it is checked in a DBC order form 24 according to FIG. 4 whether one of the selection control fields 31 or 32 is clicked with the mouse has been. Steps 43 and 46 or 45 and 46 , as have already been described above, then take place.

Following the re-executed step 46 , the value M is checked again. If M = 2, the DBC order form is completed and a DBC order process can be initiated, which is explained with reference to FIG. 7 becomes.

FIG. 7 shows a flowchart to illustrate an exemplary sequence when ordering a music CD.

In step 47 , a check is carried out to determine whether the "OK" field 33 or the "Delete" field 34 has been clicked in a displayed DBC order form 24 according to FIG. 4, preferably with the mouse. In the event that the "OK" field has been clicked, a completed DBC order form is displayed in step 48 for control purposes 35 in accordance with FIG. 5 for checking the entered data.

In step 49 , a check is carried out to determine whether the “order” field 36 or the “cancel” field 37 in the DBC order form for control purposes 35 according to FIG. 5 has preferably been clicked with the mouse. In the event that the "order" field has been clicked, the corresponding data representing the completed DBC order form is sent to a corresponding provider in step 50 and the DBC order process is completed, which is done by hiding the DBC order form. Order form for control purposes 35 according to FIG. 5 is represented.

In the event that the "delete" field was clicked in step 47 or the "cancel" field in step 49 , the data representing the displayed DBC order form is deleted in accordance with step 51 and the display of the DBC order form or the corresponding DBC order form for control purposes, which in turn ends the DBC order process.

A particular advantage of the present invention is that music CDs from with accompanying pieces of music in the form of a program offering via DBC Additional information can be transmitted and received by sending a electronic order form can be ordered. Here, data from a client computer to a corresponding facility Network control system that represents a provider, one being sent This data is transmitted unidirectionally. In particular, it must for example, no bidirectional internet connection between a client Computer of a customer and a corresponding server computer of a provider are created, as is the case in so-called e-commerce according to the prior art is common. Thus, a time-saving and cost-saving process becomes electronic Ordering music CDs provided, further based on the above Transfer of encryption codes meets the highest security standards and thus secure transmission of credit card numbers or, for example other sensitive data.

According to a further embodiment of the present invention, the above described DBC commerce system not only for the distribution of music CDs  be used, but for the distribution of any products and services, for example of software products, video films or books.
