The receiver 2 reads the received control sign as a digital sign chain into a memory 6 and is analyzed by a syntax analysis system 4. That is, it is sequentially interpreted by means of the analysis.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for transmitting communication information having a plurality of symbols from a transmitting device to a receiving device, said communication information comprising a plurality of predetermined matrices. It relates to a method of the type having an indication matrix, which is to be indicated by an indicating device of the receiving device and in which one symbol can be indicated in one matrix element. The invention likewise relates to a corresponding communication information transmission device.

[0002]

BACKGROUND OF THE INVENTION Although applicable to communication transmission methods in any technical system, the present invention, and the problems upon which it is based, relate to the communication information (news) transmission in a traffic information system for vehicles. This will be described in detail.

[0003] As the demand for communication information transmission increases and the number and variety of service services provided in the transmission of communication information increase, the demand for visual output media or displays for communication instructions also increases. I have.

In the mobile area, the display for outputting communication information is often very small, while when the receiving device is fixedly integrated,
Displays are usually relatively large and therefore relatively flexible.

As a rule, relatively long lines of text of the communication information have to be indicated on screens of different sizes. This is especially true for paging-supported information services such as, for example, Quix and Skyper, as well as traffic telematics systems where RDS / TMC messages are indicated, GSM traffic information services whose location is visualized in navigation systems and GSM Short Message (SMS
Service) in particular applies to mobile telephones carried by Cell-Broadcast.

[0006]

The problem on which the invention is based is that the relatively long lines, which are part of the communication information to be transmitted, also generally have a large number of outputs with different display capacities. The purpose of the present invention is to make it possible to display on a device in an understandable manner each time.

[0007] In optimizing text for small screens, such as a car radion screen, which may consist of only one row and eight columns, the result for the same text is when they are displayed on a large screen. Is dissatisfied. Conversely, when optimizing text for large screens, the result is usually no longer understandable on small screens. Furthermore, it is often not possible or meaningless to optimize the line of text to be indicated uniquely for the screen or display used. Such a situation arises, for example, when the geometric data of the screen is not known or can not be taken into account when sending out the text lines.

[0008] An example for this is the transmission of text to different receivers via radio radiation. The text on traffic obstruction, which is transmitted via GSM cell broadcast, can be received by different terminals, from simple handy to driver information systems with large screens. So by creating and sending out specially structured communications for any type of display or screen,
The costs are very high and the radio traffic becomes overloaded.

Another example is the output of a location on a digital map to screens of different navigation systems that can be used in a navigation system.

In the prior art, the problem of displaying communication information on a screen can be solved only insufficiently. Basically for this, three different methods apply. Common to all of these methods is that the algorithms for implementing the method are all fixedly contained in the output device.

The first and easiest way is to cut short. Text transmitted from the transmitter, when it is larger than the screen, is shortened or trimmed to the size of the screen, left justified or right justified. An example of this is the communication information “the qu
ick brown fox ”is“ the qui
c ”.

The second method is row modification. In doing so, the long text line is automatically converted into a plurality of relatively short lines. Then these short lines are indicated. However, this method can only be applied when enough lines are available for the screen to simultaneously display multiple lines of communication on the screen. For example, in an eight column display with three rows, "the quic", "k
brown "," fox ". Alterations are usually made at word boundaries, but this cannot be done with reasonably long words, so words are read as separate words. Are separated in a way that can be very degrading. Indeed, "the", "quick", "brown", "fox"
Requires four lines, but is relatively easy to read.

[0013] The third method is scrolling. Different parts of a text line are indicated at different time parts by means of a screen device or, in general, an output device or, if appropriate, a specific control function of the receiving device. For example, the text "thequick brown fox" is time-controlled and scrolled on an eight-row display. "The quic" appears in the first second, "he quick" appears in the second, and "e quic" in the third.
"k" appears and ... in the eleventh second, "brown fox"
Appears.

[0014] All of these methods are applied in different terminals. Experience has shown that the smaller the screen size of the device, the less likely it is to implement a complex algorithm in the device.

In the known approach described above, the fact that the development of communication text on the screen of the terminal cannot be controlled from the transmitter has proved to be disadvantageous. As a result, comprehension and user convenience are impaired.

Indeed, in data technology, for example, the programming language TeX, Rich Text Format (RTF), Hypertext Makeup Language (HTML)
Language) or Structured General Makeup Language (SGML = Structured Generalma)
There are various ways to define text, whether printer or screen, independent of the output device, as implemented by the rkup language. However, these languages are complex, which precludes their use in pagers or other simple terminals. Further, there are no certain programming language elements required to direct a line of text to any small output device.

[0017]

According to the present invention, there is provided a communication information transmission method having a configuration according to the first aspect of the present invention, and a second aspect of the present invention. Is solved by the communication information transmitting apparatus having the configuration described above.

The communication information transmission method and the communication information transmission device of the present invention have the following advantages over the above-mentioned known solutions: In a simple manner, a text line can be transmitted from a transmitter. A large number of different outputs so that they can be displayed significantly on screens and displays of various sizes, in which the number of symbols that can be displayed on one line as well as the number of lines that can be used are significantly different. It has the advantage of allowing it to be able to be sent to the device. This has the advantage that the communication information can be displayed in such a way that it is still easily readable and understandable for a user of the screen, which has only a small display capability.

The idea on which the invention is based is that each communication is provided with a control symbol whose meaning is explicitly or implicitly defined between the transmitter and the receiver. By means of these control symbols, the possible decompositions and shortenings are predetermined for the respective communication information, i.e. by elements which should appear on the output device, necessarily or optionally, i.e. depending on the capabilities of the output device. It is predetermined. The output device is pre-connected to the original output with an algorithm for breaking down the received text lines into possible partial representations. The different partial representations form a series of possible output line information. One of a number of possible output row formats is selected and output, depending on the algorithm present in the output device.

[0020]

BRIEF DESCRIPTION OF THE DRAWINGS The dependent claims describe advantageous forms and improvements of the communication information transmission method according to claim 1 or the communication information transmission device according to claim 5.

According to an advantageous embodiment, the control symbols are embedded in the symbols of the communication information, wherein the grouping of the component parts of the communication information between the two control symbols and the crossover of the control symbols are performed. it can. From this it follows that the method of the invention has a very wide area of use and (original)
This has the advantage that control symbols can be quickly and effectively assigned to the communication information before its transmission.

According to another advantageous embodiment, in order to determine the indicating format, all possible forms of the indicating format, which are possible by means of the arrangement of the control symbols, are determined and then the shape of the indicating format which is optimal for the respective indicating device Is selected. The shape of the pointing format can therefore be very well matched to the respective pointing matrix, i.e. a certain number of rows and columns provided on the pointing device for the display of symbols. This systematic determination of the optimal shape of the indicated communication information is only possible with the method according to the invention.

According to another advantageous embodiment, when the component part has to traverse the path in each case from the beginning to the end, the component part is obligatoryly indicated to the indicating device, and And / or optionally indicates the component part when the component part can traverse the path from the beginning to the end, and / or one or the other of the two component parts pass the path from the beginning to the end. When required, the two component parts are selectively indicated.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

FIG. 1 schematically shows the configuration of an embodiment of the apparatus used for the method of the present invention.

FIG. 1 shows a transmitter with the reference number 1,
2 indicates the receiving device, 3 indicates the processing unit, 4
Denotes a parser, 5 denotes an output device in the form of a row display and 6 denotes a memory.

The transmitter 1 sends communication information of a predetermined length to the receiving device as indicated by the arrow. This communication information includes control symbols, as described later. The receiving device 2 includes a processing unit 3 for receiving and processing communication information, a parsing system 4 for analyzing the communication information, and an output device 5 having an output line of a predetermined length. . This output device is used as a display for outputting communication information analyzed by the syntax analysis system 4. The memory 6 is advantageously provided for temporarily storing the communication information and the analysis results of the parsing system 4. Other components of the receiving device 2 are omitted to make FIG. 1 easier to understand.

The transmitter 1 and the receiving device 2 are divided in this embodiment into different devices, for example two GSM mobile telephones, one being the transmitter of the SMS short message and the other being this device. Receive and indicate SMS short messages.

In all the texts of the communication information to be transmitted,
Prior to transmission by the transmitter 1, certain additional information is added to control the output to the screen or display. These additional information are generally referred to below as control symbols. The communication information is then transmitted together with the control symbols and received at the receiving device 2 and read into the memory 6 as a digital symbol chain and the parsing system 4
, That is, interpreted sequentially by the analysis.

The control symbols divide the text line into individual sub-blocks or tokens. These consist of individual (partial) symbol chains. The output matrix of the indicating device 5 is finally indicated by a subset determined by the control symbols, i.e. the sub-amounts of the rows. It most advantageously has text symbols as large as the original communication information having the largest size. At that time, the control symbol is of course not displayed.

The following steps are performed to analyze the received communication information by means of the control symbols: (1) receiving the communication information containing the control symbols and storing the same in the memory 6;

(2) Analyze the text line analytically and break it down into component parts or "tokens" corresponding to the control symbols contained in the text line.

(3) The tokens are sequentially and branched and structured as a list. The list is stored in the memory 6. In that case, the entire possible path from the beginning to the end along the evaluation path of the line, such as arises from the interpretation of the control symbols, is determined by the pointing device 5 for the selection of the output line which is subsequently selected as optimal. Form the basis

A token may have the characteristic "mandatory" or "mandatory"("") when it must traverse the path from the beginning to the end of the line in each case. obligatorisch ”).

When a token can traverse the path from the beginning to the end of the line, but not necessarily, when traveling, the property "optional"("option
al ”).

Two tokens have the property "alternate" when one or the other has to follow a path from the beginning to the end.

The tokens can basically be interlaced with one another, as will be explained in more detail later.

(4) Select a path inside the device that is suitable for display in the existing screen geometry and assemble a line from the tokens passed on this path between the start and end.

(5) Output the text to the screen.

This process is repeated in the same way for each individual received text line. This is similar to the process that occurs when reading source text into a translation program for a programming language (compiler).

That is, the control symbols define a simple programming language for decomposition into transmitted text. It consists of two different parts.

In a first negotiation part, a set of symbols and control symbols for use are negotiated for the programming language. This negotiation part can be made explicitly or implicitly by the negotiation block of the advantageous method at the beginning of the communication information or the line. In the example described in more detail below, the implicit agreement is implemented using the symbol set ISO8859 / 2. In this part, specific binary values or symbols for the language elements of the programming language are also negotiated.

The choices in the control symbols and their respective meanings are summarized in the following table:

[0044]

[Table 1]

In this case, for simplicity, the displayable
Individual symbols have been selected as control symbols. However, for example, “<opt>” and “<// o” as control symbols for the elements StartOption (start option) and EndOption (end option)
More than one symbol may be used for a language element, such as pt>". In addition, symbols that are not displayable for the language element (binary codes), such as Star
It can be arranged to use binary 02 (STX) as the tGroup element.

In the above implicit agreement, the transmitter 1 and the receiving device 2 know how the language elements are mapped to the control symbols. In an explicit agreement, the control symbols are sent to an output device before the actual start of the process and parameterize the parser 4 there. In a syntax that relies on HTML, such a negotiation block can send, for example, the following line of text:

[0047]

[Table 2]

For simplicity, the same control symbols were chosen as in the above example of the implicit agreement.

The agreement can also be variably filed in a separate area of the non-volatile parameter memory, for example, the memory 6 of the receiving device 2.

Thus, the programming language elements define the structure in the communication information which consists of individual component parts, usually a continuous symbol of the (original) communication information of the communication information. The component parts can be of different lengths. These component parts or token structures are advantageously generated for individual lines of the original communication information. The individual language elements mentioned above then have the following functions in addition to the data listed in the table: StartOption and E
The control symbol for ndOption defines the start or end of the optional token. Sta
The tokens from after the rtOption symbol to before the EndOption symbol are, for example: “[quick]”
Can be removed from a line of text.

StartGroup and EndGro
A control symbol for up defines a group of symbols as a token. StartGroup and En
The control symbols for dGroup should be alternately cycled,
OrOpera to define the token list branch
By tor, for example: "{Eins | Zwei}"
It is defined as (1 | 2). That is, if both are not enclosed by square brackets ([]), that is, if they are optional, 1 or 2 can be indicated.

By EscapeOperator,
The immediately following symbol is interpreted not as a control symbol, but as a symbol to be indicated, ie, "decreased value", for example: "$]", thereby indicating square brackets.

A possible output line is composed of various tokens arranged one after the other, each token having a defined length required for the indication. The token structure is inserted into the row by the transmitter's communication information compilation before transmission by the transmitter. Then before output, the token structure is evaluated so that the existing output width of each output line is used as best as possible by the included tokens.

Referring now to FIG. 1 and to FIG. 2 which schematically illustrates the division of the transmitted communication information based on the control symbols transmitted together according to the method of the invention, A description will be given based on an example of communication information from the traffic information system.

In this case, in the receiving device 2, here a car radio set up for this purpose, the parsing system 4 is provided with an evaluation algorithm as described above. The parser decomposes the received text lines or communication information into predetermined individual parts. The different parts then form a certain amount of possible output rows. One of the possible output lines is selected and output to the pointing device 5 by any algorithm present in the car radio.

For this purpose, it is assumed that communication information on the autobahn junction (Anschulus sstelle in FIG. 2) is output as text on the display 5 of the car radio, that is, on the "screen". The text set for transmission at transmitter 1 is as follows: "A42 / E52 Anshulussstelle 43 Frankfurt am
Main Friedberger Strasse "This text is 66 symbols long. Token formation by control symbols is a task that is performed automatically or manually at the transmitter 1 independently of the receiver 2.

At this time, the communication information in the transmitter 1 is given a control symbol as follows: "A42 [/ E52] [{AS | Anshulussstelle}"
{[43}] F [rankfurt] am Main] "This text is translated into a token structure as shown in Fig. 2 as communication information after reception by the parsing system 4. At this time, the token in Fig. 2 is used. The start and end of the tour and all alternatives in between are shown, each token being shown symbolically together with its length in a respective rectangular block T1 to T9.

All possible defined language elements are used in this token structure:
Imperative tokens (T1, T7) and optional tokens (T2-T6, T8, T9) that are also interlaced
Are OR'd in group formation or in group formation with OrOperator. The display of the control symbol as text is Escape
This is done by using an Operator.

In the indicating device 5, these token structures are used for indicating at least five symbols, namely T
It requires 1 and T7, and up to 44 symbols, ie, T1 through T7. The different results are as follows from the start node shown on the left at the beginning left of the row to the end node on the right at the end of the row, at the node points K1 to K5 of the row in the structure of FIG. It is caused by having various paths. Given the possible combinations of the individual alternatives, the following paths arise to analyze this structure:

[0060]

[Table 3]

The indicating device 5 having 16 symbols can indicate lines 1, 2, 3, and 7. Which of these rows is to be selected has to be determined in the receiving device 2 itself. In the rule "maximum use of digits in the instruction matrix", which can be called "simple", in this example Nr. 7 or "A42 Frankfur
t ”will be indicated.

The method according to the invention for transmitting communication information therefore allows an understandable output on an output device of any indication format, which can be used by the transmitter 1 for output. You do not need to know the number of columns in the instruction matrix. Even if not known, the communication information is displayed line by line so that they appear optimally readable to the reader.

Although the invention has been described with reference to the preferred embodiment, the invention is not restricted to this, but can be modified in various different ways.

The transmitter 1 and the receiving device 2 can be combined, for example, into one device, for example, an RDS / TMC car radio device in which the transmitter responds to a list of locations stored on the chip card. In that case, processing unit 3
Is an interface inside the device.

In particular, according to the principles described above, it is also possible to process special symbols of another symbol set or image information which is formed on the basis of pixels.

The method and the device according to the invention are particularly suitable when text is transmitted to an output device via an air interface, for example a GMS short message service, or when text lines are inserted into a data carrier in a terminal device. ing. Such an example would occur when a commonly available data CD, such as "Tele-Atlas", is inserted into a particular navigation system.
