Description
The present application is based on Korean Patent Application No. 35288/1995 which is incorporated herein by reference for all purposes.
The present invention relates to a character display apparatus for an intelligence television. More specifically, the present invention relates to a character display apparatus which enables textual and/or other information from a communication service to be simultaneously displayed on the intelligence television with a broadcast signal.
An intelligence television includes an information processing system which is connected to a value added communication network (VAN) to enable it to receive communication data from the VAN. After receiving such information, the processing system outputs red, green, and blue (RGB) information signals which correspond to the communication data and outputs a related switching control signal. The television also contains RGB switches located inside the television receiver for switching between television RGB signals received via an antenna and the RGB information signals output from the information processing system. In particular, the RGB switches switch between the two types of RGB signals in accordance with the switching control signal output from the processing system.
Since communication information relating to various communication services (e.g. securities information, news, weather, and television programming information) can be transmitted via a VAN and viewed on an intelligence television, a viewer who is not skilled in computers can conveniently obtain the communication information. However, the intelligence television cannot display the communication information immediately after it is received and cannot display it while the viewer is watching a broadcast television program. Accordingly, an apparatus which enables a viewer to view the communication information while it is being received and/or view such information simultaneously with a broadcast television program is needed.
In order to overcome the above disadvantages, an object of the present invention is to provide a character display apparatus for an intelligence television in which characters can be displayed on the top or bottom of a screen and move from one side of the screen to the other side of the screen while a viewer is watching television.
In order to achieve the above object, a character display apparatus for an intelligence television which is capable of simultaneously displaying a television broadcast signal and a communication signal corresponding to communication service information supplied via a value added communication network is provided. In particular, the display apparatus comprises: an information processing system which receives said communication service information from said value added communication network and outputs a corresponding screen information signal and a switching control signal; signal switching means for selecting and switching between said screen information signal and said television broadcast signal based on said switching control signal and for outputting a corresponding selected signal; a display driver which inputs said selected signal, superimposes an on screen display signal onto said selected signal to produce a superimposed signal, and outputs said superimposed signal to a display; and a microcomputer which outputs an actuating signal to instruct said information processing system to receive said communication service information from said value added communication network and which outputs said on screen display signal to said display driver.
Accordingly, the viewer can view the communication service information while simultaneously watching television. Also, since the information may be displayed as a line of characters which successively moves across the screen, displaying the characters on a limited portion of the screen is possible.
The above objects and advantages of the present invention will become more apparent by describing in detail preferred embodiments thereof with reference to the attached drawings in which:
FIG. 1 illustrates a character display apparatus for an intelligence television in accordance with one embodiment of the present invention;
FIG. 2 illustrates a conventional on screen display (OSD) character display apparatus;
FIG. 3 is a flow chart showing an operation of the microprocessor and information processing system illustrated in FIG. 1; and
FIG. 4 illustrates an example of how communication information is displayed by the present invention.
The following description of the preferred embodiments discloses specific configuration and components. However, the preferred embodiments are merely examples of the present invention, and thus, the specific features described below are merely used to more easily describe such embodiments and to provide an overall understanding of the present invention. Accordingly, one skilled in the art will readily recognize that the present invention is not limited to the specific embodiments described below. Furthermore, the descriptions of various features and structures of the present invention which would be known to one skilled in the art are omitted for the sake of clarity and brevity.
FIG. 2 illustrates a conventional on screen display (OSD) character display apparatus. Specifically, the apparatus comprises a cathode ray tube (CRT) driver 200 which inputs an RGB television signal and an RGB OSD signal and which superimposes such signals to produce a superimposed signal. Subsequently, the superimposed signal is output to and displayed by a CRT 300. In general, the OSD characters represented by the OSD signal and the position at which the characters are to be displayed on the CRT 300 are determined by an OSD character generator that supplies the RGB OSD signal to the CRT driver 200. Furthermore, since the RGB OSD signal is selected before the RGB television signal is selected, the OSD characters are superposed on the RGB television signals and displayed on the CRT 300.
In the present invention, communication information is displayed on an intelligence television, and the characters corresponding to the information may be simultaneously displayed on the television with a television broadcast signal. For example, the characters may successively move from the right of the screen to the left of the screen as the television broadcast signal is displayed.
FIG. 1 illustrates a character display apparatus for an intelligence television in accordance with one embodiment of the present invention. As shown in the figure, the apparatus comprises a signal switching portion 100, a CRT driver 200, a CRT 300, a microcomputer 400, and an information processing system 500.
The processing system 500 is connected to a value added communication network (VAN) and receives communication information relating to a value added communication service. After receiving the information, the processing system 500 converts it into an RGB screen information signal and outputs the signal to the signal switching portion 100.
The signal switching portion 100 inputs the RGB screen information signal and an RGB television signal and selectively outputs one or both of the signals as a selected signal. For example, the switching portion may output only the RGB screen information signal, only the RGB television signal, or the RGB screen information signal superimposed upon the RGB television signal as the selected signal.
The CRT driver 200 inputs an OSD signal and the selected signal and superimposes the OSD signal upon the selected signal to produce a superimposed signal. Then, the driver 200 outputs the superimposed signal to the CRT 300 so that the signal can be displayed.
The microcomputer 400 generates and outputs an actuating signal to the information processing system 500 to command the processing system 500 to input communication information from the VAN. Also, the microcomputer 400 generates the OSD signal which is output to the CRT driver 200.
The operation of the character display apparatus will be described in more detail below. When the microcomputer 400 outputs the appropriate actuating signal, the information processing system 500 begins receiving communication information from the VAN, decoding the communication information, and outputting corresponding RGB screen information signals. Furthermore, the processing system 500 contains an information control unit 540 which comprises a CPU (not shown), a program read only memory (ROM) (not shown), a main controller (not shown), a digital-to-analog (D/A) converter (not own), a palette random access memory (RAM) (not shown), and a memory portion (not shown).
The CPU performs various control functions, transmission functions, and other data operations relating to the system 500. The program ROM stores programs which are necessary for the operation of the system 500 and stores various types of data which are utilized by the CPU. The main controller generates control signals which are used to control the overall operation of the system 500 and which are used to receive, display, and process the communication data. The D/A converter receives graphics data from the main controller, inputs RGB signals from the internal palette RAM, and converts the graphics data and RGB signals into analog signals. Furthermore, the memory portion reads and writes communication data under the control of the main controller.
The information processing system 500 also comprises a modulator-demodulator (MODEM) 530, a first in first out (FIFO) memory 520, and a display position setting portion 510. The MODEM 530 transmits data to or receives data from a host computer (not shown) via the VAN under the control of the main controller. The FIFO memory 520 successively stores the data input from the MODEM 530 and outputs such data in accordance with a reference clock signal.
Then, the display position setting portion 510 inputs the data from the FIFO memory 520, determines the position of the CRT 300 at which such data will be displayed, and outputs the data as an RGB screen information signal. In addition, the setting portion 510 outputs a corresponding switching control signal.
The signal switching portion 100 inputs the RGB television signal supplied by a source (e.g. a cable or an antenna) and the RGB screen information signal. Then, the switching portion 100 performs the switching operation on the two RGB signals based on the switching control signal output from the processing system 500. For example, the switching portion 100 may output only the RGB television signal or may output the RGB screen information signal superimposed upon the RGB television signal based on the switching control signal. Then, the resultant signal is output as the selected signal to the CRT driver 200.
The microcomputer 400 generates an OSD signal for displaying various information (e.g. the current volume setting, the currently tuned channel, and the current time) and outputs the OSD signal to the CRT driver 200. The driver 200 inputs the selected signal from the switching portion 100 and the OSD signal from the microcomputer 400 and superimposes the OSD signal on the selected signal to produce a superimposed signal. Then, the superimposed signal is transmitted to the CRT 300 in order to display it on the CRT 300.
FIG. 3 represents a flow chart which further describes the operation and interrelation of the microcomputer 400 and the information processing system 500. For example, one manner by which the communication information may displayed on the CRT 300 is if the viewer presses an information key on an input device (e.g. a remote control) (step S32). If the key has not been depressed (step S34), the microcomputer 400 maintains the apparatus in a television mode (step S36).
On the other hand, if the viewer has depressed the information key (step S34), the microcomputer 400 generates and outputs an actuation signal to instruct the processing system 500 to establish a connection to the VAN via the MODEM 530 (step S38). Consequently, the communication information is transmitted from the host computer to the information processing system 500 via the VAN and stored in the FIFO memory 520 as stored data (step S40).
The FIFO memory 520 successively transfers the stored data to an internal upper register based on the reference clock signal, and such data is successively output to the display position setting portion 510 (step S42). For example, if the communication information corresponds to textual information (e.g. a sentence), the textual information may be output to the display position setting portion beginning with the first character of the sentence.
In addition, the display position setting portion 510 inputs horizontal and vertical synchronization signals H-SYNC and V-SYNC and calculates the position at which the communication information is to be displayed on the CRT 300 based on such signals H-SYNC and V-SYNC. Then, the portion 510 outputs a signal to the switching portion 100 which relates to such position. For example, the position at which the information is to be displayed may be contained in the switching control signal output by the setting portion S-10. As a result, the communication information which is output to the signal switching portion 100 as an RGB screen information signal may be superimposed on the RGB television signal in accordance with the switching control signal. Consequently, the communication information may be displayed on a position of the CRT 300 which corresponds to the position at which the information is superposed on the RGB television signal.
One example of the manner in which the RGB screen information signal and the RGB television signal may be displayed on the CRT 300 is illustrated in FIG. 4. As shown in the figure, the RGB screen information signal corresponds to the phrase “TODAY HEAVY RAIN”, and such phrase sequentially scrolls from the right side of the CRT 300 to the left side of the CRT 300. Furthermore, the RGB screen information signal can be displayed simultaneously with the RGB television signal and can be displayed immediately after it has been received by the information processing system 500. As a result, a foreign movie and communication information which is transmitted via a VAN (e.g. news information which is displayed as written text) can be simultaneously displayed on the television without having to display a screen which is dedicated to displaying the communication information.
The previous description of the preferred embodiments is provided to enable a person skilled in the art to make or use the present invention. Moreover, various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without the use of inventive faculty. Therefore, the present invention is not intended to be limited to the embodiments described herein but is to be accorded the widest scope as defined by the claims.
