"System serving the handling and delivery of data"

045/0376

3 -

The invention relates to a system used for handling and delivering data.

In particular, the system according to the invention is such arranged that there would be an indefinite number of participants on a simple request with information supplied / without the interrogation of a central dispensing unit required and the arrangement more specialized with the delivery unit connected lines is necessary. The system according to the invention sets the subscriber in a position to have all the information you want, even if the central delivery unit is temporarily stopped.

All known systems for the transmission of information to a plurality of participants speak to one logical configuration that they connect together; i.e. there is always an automatic or manual actuatable dispensing unit to which the participants' questions lead.

The central delivery or storage units have a large amount of information and the subscriber

directly requests part of this information by requesting the central unit itself and then receives the answer.

Newer systems use the technology of continuous or cyclical transmission of all information, that they have, while the subscriber has a receiving device that is capable is to select only that part of the information that he needs by means of one through him and only known to him entered coding.

In the former case _7, when an immediate request from the subscriber is required, problems arise with regard to the speed and the ability of the central delivery unit with regard to the selection and transmission of each individual information requested from the subscriber. In the second case, in which the selection is made by the participant himself, the requested information is only received if the information is transmitted cyclically, so that the exact cycle must be awaited. In both cases, each time the central delivery unit fails, the participant is presented with the desired information.

contain.

The system according to the invention differs from the known systems in that the central Dispensing unit is able to directly provide the entire information available to the individual participant or To transmit a group of participants without a special request is required, since each participant or each subscriber group is provided with a local storage arrangement so that all required information can be received at any time, without any waiting, and even when the central unit is itself out of service.

In addition, the central unit is able at any moment to view all of the subscriber's devices Bringing information up to date by deleting the information that is no longer required and entering new information in order to be completely independent of the central dispensing unit to reach.

The invention is then based on a preferred

show the embodiment shown in the enclosed Drawing is shown, described.

The system consists of a central assembler 1 for storing and organizing the information an encoder 1a with different ways A, B, C, for example alpha-numeric key values, Teleprinters, recorder tapes, etc .; a transmission or buffer memory 2 is also specified in FIG the line by line all information is entered by the central unit 1; a transfer unit The purpose of 3 is to read all lines of the memory 2 and to send their content via a common line 4 transmitted, which connects all participants with each other and with the central unit 1. The reference characters 5 to 5n denote the subscriber devices. Each subscriber device has a local memory 5/1, which completely corresponds to the buffer memory 2 of the central unit 1. In the local storage there are 5/1 under the control of the transfer unit 3, all lines of information are stored in accordance with the memory. A local selector 5/2 is used to select all the information lines one after the other by direct reading from the local memory 5/1 depending on the

The inventive system has a local central unit for receiving and storing of information that is connected via a common line to a plurality of peripheral Teilnehxnergeräten t of which jedesmit its own memory unit is provided for receiving and storing all ,, information contained in the central memory . The subscriber's own memory unit is designed in such a way that it allows its use independently of the central unit 1, means being provided for bringing the information contained in the subscriber's own memory up to date.

according to the system ο

First of all, how that of an external one is executed
Source via the paths A, B, C incoming information can be entered into the memory 2.

Lots of information, such as a written one Text is divided into pages and lines.

Each page has a maximum number of lines depending on the display unit, for example one Television screen.

Each line of text has a maximum number of characters and spaces depending on the size of the display unit 5/3. The subscriber may wish to have an entire page rather than only one or more lines displayed, for example messages can comprise an entire page, for example as a list
of museums with their addresses, telephone numbers and
Opening hours. A timetable for transportation or a security on the stock exchange can only require one line, and the participant should be able to post his
special information on your own decision

that he wishes to receive from his own device and only this information from one Variety of information stored.

To make this possible, all sides and all are Referencing lines when they are entered into memory 2.

Each page is distinguished from the other pages by an alpha-numeric character. Every line is different separated from all other lines on the same page by an alphabetic character. The whole Information made up of the alpha-numeric characters of the lines, each with its own Identification code is specified, are stored in the memory 2 and are always ready for Transmission to the participants.

In order to bring the transit memory 2 up to date, new lines can be entered in it, which are previously provided with page and line encodings, and the character by character the earlier lines substitute.

After they have been saved, the lines are

Then, the arrangement and construction will be described of the device of the user ", through line 4, the connection is made with the memory unit 5/1, which means that the entire _# codified" and line by line and page by page in the memory 2 level information is transmitted from the central unit 1 to the memory of the subscribers, so that the operational lines of the central unit 1 are completely independent of the customers.

030045/0376

This is a characteristic feature that distinguishes the invention from the known systems where the central unit and the participants work simultaneously, with the result that the participants cannot work if the central unit 1 fails.

The subscriber's memory unit 5/1 is assigned a selector 5/2 which is controlled by the subscriber is entered by entering the coding of the page and / or the line he wishes to receive.

Behind the selector 5/2 a display device 5/3 and / or a further memory is connected to the further Use of the information taken from the memory 5/1 by the subscriber.

It is clear that the display of the information by the subscriber is in no way dependent on the operation the central unit 1 at the moment of the display.

The following are the characteristics of the system according to the invention.

First, the special type of input of the in-

formation in the memory 2 described.

All information is entered by an operator, by means of a known, alpha-numeric key table, not shown, which defined a Number of characters of each word group having lines transmits, which forms the information itself.

The operator has to take care that each line is provided with characters that represent the pages and the lines Show.

The continuous scanning of the input memory 2 interrupts itself in the event of a coincidence of the Page and line coding and opens the input path of the message on the selected line so that the operator can complete the message stored in the available space of the memory will. Other information was previously stored in the same space as the new information is replaced so that a new message is created.

The sequence in which the characters are stored

030045/0376

allows you to put them all in columns so that the first two (page and line) are always on the same column are present at the head of the message, which can take up the size of an entire line or not.

Once stored in the memory line by line, the message can be used at any moment for the Participants are displayed.

The following step is carried out automatically, cyclically or imperatively by the transmitter 3.

This consists of a scanning display unit that can display the contents of the entire memory by adding it delivers the entire contents to the memory 5/1 etc. through the line 4, which the subscribers for Are available so that the participants' memories are brought up to date line by line. Since the transmitter transmits each line specified by its own coding, it is not necessary to to set the lines in some natural progression, it is sufficient to mark each line with a side and a line coding.

Then it is shown how the participant can select information.

The participant has a memory 5/1 in which all of the lines transmitted by the transmitter 3 are contained as a column, and via a selector with an alpha-numeric key table 5/2, which has the task of providing the desired information starting from the page and line coding.

When the participant wishes to receive an entire page, he carries the character designating the page into the selector, and if it wishes to receive only one or more special lines, it executes the page coding and the coding of the desired line in the selector.

As stated earlier, the lines in memory can be arranged in any order, even in columns summarized, starting from the initial coding. The display device guides the display along the Column through, starting from the code characters, to first the page and desired line through the key table to locate.

03D0A5 / 0376

Reading is carried out column by column, starting from the code characters, so that is practical Waiting times, which would be necessary if the reading were to be carried out line by line, are avoided because of this reading all the lines takes a much longer time than just reading them the column.

This feature characterizes the invention and enables it to be reproduced in real time since the short time required to read the column, practically not noticed by the participant who thus has a sense of instantaneousness.

The invention is not limited to the embodiment shown, but can be modified within the scope of the inventive concept.
