Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a television system installed at terminals such as stock exchange stores, etc. that transmits stock price information from, for example, a stock exchange through a communication line of a public corporation. The present invention relates to an improvement in a display control method for receiving and demodulating stock prices in a stock price display device such as a stock price display device, and displaying the stock price as the current stock price.

(Conventional technology and its problems) In the stock price reporting line in the stock market information transmission system, information data is unilaterally sent from the stock exchange to terminals (stock stores, etc.) distributed throughout the country, and this data is not sent to the end. It is well known that images are processed by a device and generally displayed on a plurality of cathode ray tubes, display boards, etc. (hereinafter referred to as display devices). It is customary to display data for each stock issue on the display screen, such as opening price, high price, low price, current price, and change from the previous day. If the system is configured such that the last day's data for a stock (for which there is a stock) is sent with the stock code, and after that, only information about the stock whose stock price has been updated is sent, then the display and control The information data storage device (RAM) in the control section of the stock price reporting device consisting of the section stores all the data initially sent or the data of all the required stocks, and repeatedly sends this to the display using a control signal. it's shown. It is also well known that data is updated by rewriting the corresponding portion of RAM using the sent update data. Therefore, if there are many stocks for which you want to display stock price information on a terminal, multiple displays are required, and depending on the number of display lines, 16
(number of brands displayed: 512 to 256) to 4 (128 brands) are used. If the display screen is one screen, it is possible to read individual data from memory (RAM) using a keyboard or the like and display it individually, but it is difficult to quickly switch data for a large number of brands. The major drawback is that it cannot be displayed. For convenience, such a display method will be referred to as non-listability. In addition, a CRT display that uses a large number of displays has the ability to at least list the most desired brands, but it is not suitable for displaying data on any brand individually, and the display area occupies a large area. It is inevitable that it will be expensive.

(Object of the Invention) The present invention performs processing that incorporates the advantages of a display method having multiple display screens and a non-list display method, and is capable of displaying individual stock price information, as well as displaying a predetermined information book. The present invention provides a method for displaying stock price data at a glance by using a designated signal for simultaneously displaying stock data on a desired page.

(Structure of the invention) This will be explained in detail below.

The drawing is a diagram showing an example of the configuration of a stock price display device embodying the present invention. In this figure, 1 is a data communication line to which this stock price display device is connected as a terminal.
For example, a stock price information signal indicating the name of each stock and its stock price is sent sequentially at a speed of 1200 baud. Reference numeral 2 denotes a line input section, which includes a main distribution board, an indoor distribution board, a protector, etc., and signals are input to the control section 3 through these sections. The control unit 3 includes a demodulator,
It includes a communication control circuit, a television control circuit, etc., and after checking the received and demodulated stock price information in the communication control circuit, sends it to the television control circuit, temporary memory circuit (RAM) 4, etc. The television control circuit includes a character generation circuit and a video signal output circuit for displaying the brand name from the brand code.
The output is sent to the display (CRT) 6 and the stock price is displayed, but since these circuits are well known, their explanation will be omitted. 5 is a specified brand storage device such as a cassette or floppy disk (hereinafter referred to as memory); 7 is a keyboard that can generally be installed in multiple units to correspond to the number of CRTs 6; 8 is an information block whose contents are stored in the memory 5. There is no substance as it has been recorded in advance. Although 4 and 5 are shown outside the control unit 3 in the figure for convenience, they may actually be provided inside.

Next, the operation of each part will be explained.

The control unit 3 stores all the received stock price information in RAM 4 provided internally or externally, replaces the data for each brand when new data is sent, and stores the stock price information in RAM 4. The purpose of this invention is to display on the display 6 using a specified brand code, but the present invention is characterized by the method of specifying the brand. First, information book 8
For example, nine predetermined brands are displayed on one page of the display 6, for example, up to 32 brands.
A plurality of pages worth of stock designation codes are recorded in advance in the memory 5 as an information book 8.

Further, stock price information sent from the data line 1 is input to the RAM 4, and the latest information is read by successively updating the old information. That is, the RAM 4 includes two areas, an information book area and a stock price data area. The keyboard 7 is provided with various keys in addition to a numeric keypad, and when the operator presses these keys, various displays can be made through the control section 3.

After turning on the power, use the numeric keypad to specify a page in the information book 8 and then press the page key. Data for all stocks on the specified page, that is, stock price information including stock names, will be displayed on the display via the television control circuit in the control unit 3. In this way, shown in 6,
Data can be displayed for each page. Further, for example, when a request is made to display data for an arbitrary brand, if the brand is in the information book 8, the latest data will be displayed by specifying the page number. If the brand whose data is requested to be displayed is not included in the information book 8, it can be displayed from RAM 4 using the brand code.
It is also possible to move or delete the line displayed on any page of the information book 8 and enter data for any designated brand in its place. Note that in order to change the designated brands on a certain page of the information book 8, it is sufficient to change the contents recorded in the memory 5, and this can be done in advance using another device or this device, but the technology for doing so is not known. I'll omit it because it is.

(Effects of the Invention) As described above, the following practical effects can be obtained by implementing the present invention.

(1) Stock price inquiries and operations (displaying stock price data) are simplified, and stock information reference speed is increased. In other words, inquiries regarding stock price information, which changes from moment to moment, can be made quickly.

(2) Since the trading status of the stock being queried is automatically updated, there is no need to re-query.

(3) A list display is performed using the information book method,
Since multiple screens are not required, the display area is small and can be downsized.
