Detailed Description of the Preferred Embodiments Figure 1 shows a data-processing block diagram of dual process total-processing service function unit having a memory mapping program to store the date for prearranged watching, telephone directory, 2~ 62 birthday, wedding anniversary, and display characters on the screen at a desired time.
Screen control unit (7), syncronous signal generation circuit(6) and input-output control unit(2) are mutually connected through data address bus with central control unit (4) and operation memory (10-12). Said input-output control unit (2) is connected with micom (1) receiving the signal of a remote cont~oller (3) to exchange data signals ( RxD, RxC, TxD, RTS ) and also connected with signal generation circuit (6) to apply interrupt signal thereto.
Interrupt(INT) control signal of said central control unit(4) is gone through decoder(~) to common clip enable terminals (CE) of said operation memory (10-12).
Decorder (5) which transf~m coded signal lnto a correspondent control signal is connected to incentive signal generation (6), input-output control unit(2) and common enable terminal (CE) of screen control unit(7). Said central control unit (4), in case of having no designated signal from micom(1), receives a periodic signal from syncronous signal generation circuit (6) to periodically check said operation mermories (10-12) and outputs a reserved data to screen control unit(7) in accordance with an assigned address, thereby displaying the data stored in said operation memory (10-12), such as programed birthday, wedding anniversary, telephone diretory on the screen.
As shown in Figure 2,in the video band selection processing unit, clock terminal (CL), enable terminal (CE) and date terminal (D) of said micom (1) syncronized by a signal forwarded by a remote cont-roller (3) are connected through pull-up resistances (Rl-R3) supplied by the electric power (Vc) to D/A converting unit (17), transmitting by way of internal IM bus interface to 8 bite D/A converter (20).
Out terminal (Xout) and input-terminal (Xin) of said micom (1) are connected with oscillator (Z) and buffer (16) comprising of condensor ~C1-C4) resistance (R4-Rs) and transistor (Q1). Said Xout is arranged to convert through clock driver (19) of said D/A converting unit (17) to said 8 byte D/A converter (20). Each Xout of said D/A converter (17) is linked to resistances respectively ( R6-Rs, Rs-R11, R12-R14, R1s-R17, R1s-R20 ), further connected through low-pass filter unit (22) composing of condensors (Cs-C16) and coils (L1-Ls) to brightness terminal (B), contrast terminal (C), color terminal (Co), tint terminal (Ti), sharpness terminal (sh) respectiely, thereby selecting a color tone corresponding to the mood of televised program by video mode selection key on said remote controller (3).
As shown in Figure 3, the sound selection processing unit is composed to select a mean value of phonetic pressure for a proper sound corresponding to the contents of a televised program.
Audio signal of swing port (AD1, AD2) of said micom(1) is connected to audio signal switching IC circuit (2~), which is then linked to high-pass band (26), medium-pass band (27), low-pass band (28), medium to low pass band (29) of equalizing circuit (25) which is classified by the level of phonetic pressure, and the other end of said band (26-29) is applied by left and right phonetic signals (L1, R1), thereby selecting a sound appropriate to the atmosphere of TV program by audio mode selection key placed on the remote controller (3).
- ~ 20149t~2 The present invention according to above-described composition is operative as follows.
In operating a TV set, as the switch of a remote controller (3) is touched, a remote receiver of micom(1) converts received signals into digital ones which are readable by input-output control unit (2) and inputs them to input-output control unit (2).
Then said input-output control unit inputs interrupt signal (INT) into control processing unit (4) to check the programs stored in operation memory (10-12) through address bus.
In case of receiving no interrupt signal (INT) from input-output control unit (2), in accordance with a periodic signal (INT) generated from syncronous signal generation circuit (6), central processing unit (4) checks EEPROM (12) pursuant to the designated address to output the reserved data.
Supposing that a channel conversion signal is inputted from remote controller (3), central control unit (4) operates EEPROM as above explained, so that central control unit (4) converts the screen display according to said channel conversion signal input from remote controller (3).
When a optional code from remote controller (3) is inputted to micom (1), said micom (1) converts it into a code ruled by central processing unit (4) and creates transmission clock RXCA (receive clock at sio)and its Xout transmits outgoing data RXDA by one byte to input-output control unit (2).
As a data from said micom (1) is inputted to input-ouput control unit (2), interrupt signal is generated to suspend the routine performed by central processing unit (4) and perform receive 20149~2 servlce .
In receiving from micom (1), RTS of input-output control unit(2) to perform service routine of receiving data pursuant to the generated RTS signal, creates receive clock TXCA at micom and receive incoming date TXCA by one byte.
Namely, when input-output control unit (2) has a data transmitted from micom (1), interrupt signal (INT) is automatically produced to receive a data from service routine of central processing unit (4).
At this moment, receive service notifies input-output control unit (2) that is read mode by 92nd address among I/O ports designat-ing input-output control unit and receives data by 90th address.
In transmittal, it notifies input-output control unit (2) that is write mode by 90th address and transmit data by said 90th address.
After such transmitted data is inputted to receiving buffer of said input-output control and all recorded, while syncronizing RXC~
or TXCA, central control unit (4) lets input-output control unit (2) produce RTS, forwarding low-level interrupt signal to micom(1).
In receiving a data from said micom(1), central control unit (4) decides whether to store on RAM or EEPROM of operation memory (10-12) the data recorded on buffer of said input-output control unit (2) and generates vector address to store it through date bus.
Data stored on said operation memory (10-12) through data bus is then inputted by enable signal (CE) of decoder (5) to screen control unit (7). Said central processing unit returns to the step prior to service routine and resumes the suspended rountine.
RAM of said operation memory (10-12), utilizing SRAM with 8 201~62 byte of COOO-DFFF alloted, is used to temporaily store the data readed from input-output control unit (2) or to arrange data by storing altering, deleting or newly entering the entire data EEPROM
of said operation memory (14) with 8K byte of FOOO-FFFF is used to permanently reserve the data to be stored.
When data transmitted through data bus is inputted to said screen control unit (7), the input-output part using AO-A3 address makes access to screen control unit (7).
For exanple, if port AD, H are assigned, port O of said screen control unit (7) is assigned on address line of A0, A1, thereby accessing video RAM (8) subordinate to said screen control unit (7) and having CSR, CSW made of A2-A7 and IQRD, RD & WR decide read or write mode to output R.G.B signal.
Said screen control unit (7) according to this invention, in bit map method, may use video RAM (8) up to 128K byte.
Screen control unit (7) constitutes an incencitive of R.G.B.
output by comparing vertical or horizontal signal, and switches TV signals by means of VS signal.
Said video RAM (8) allots 32K byte per each screen and regards it as one page. Page 0 is for read and write of data to be actually displayed, while page 1 is to store the style of charater received from central control unit (4) at the beginning of program.
Character or picture type of RGB signal is outputted through internal data bus by a code designating the color on page 0 to display the screen.
Flowchart in Figure 4 further describes the above process in more details.
As a data is inputted by remote control, said screen control - 2014~62 unit (7) makes YS signal high, cuts off the signal of screen control unit (7) to be outputted to a TV set, and initiates said central processing unit (4) and operation memory (10-12). It then sets the initial value of RAM of operation memory (11) and retrieves whether system is normal.
In case that the program is found abnormal, it cuts off the program, while if it is normal and any assigned program exists, it turns on the power of television and performs the next operation.
Namely, upon receiving remote control signal, central control unit~4) reads mode at RAM of operation memory (10-12), branches off register according to the mode value and turns on the main power.
Thereafter, central control unit (4) judges TV/AV mode, reserved watching mode, telephone directory memory mode, birthday or anniversary reservation mode.
If a selected mode is TV/AV mode, after completing the process shown in Figure 4 (D), it checks whether it is reserved and records the altered data entered from remote controller (3) or outputs the stored data.
Figure 4(E) (F) shows the procedure of altering and reserving the channel data stored on EEPROM of operation memory (12).
Numeric channel data includes data such as telephone number, birthday, anniversary depending on the mode selection.
Accordingly, once the state of system is confirmed in the initial routine stage and a reserved data is retrieved, entered data is outputted through respective routine, as shown in Figures (E) (F) and displayed on CRT ( 15) through said screen control unit (7) and switching part (14).
- - 2Q14~62 For example, Figure 4(G) shows the program for displaying the data of birthday or anniversary. Once the appointed data is read from data address of EEPROM, the data is outputted at micom (1) through central control unit (4) and input-output control ur.it (2).
Accordingly, message data is displayed as many as the number of data by message key, micom(1) comes melody unit (1~) into action, and screen data is displayed on CRT(15) through said screen control unit (7) and switching part (14).
In case of having the displayed data on he screen without interruption, RAM of said operation memory ~11) is read as shown in Figure 4 (H).
According to above-described process, this invention provides multi-function such as reserved watching, memory and display of birthday, telephone number and anniversary. As shown in Figure 2, it also provides video selection processing to stress a specific color tone of screen by selecting as hard or soft the color corresponding to the mode of broadcast program (sports, news, drama, music, movies). Data program mode is divided into Standard, Dark, Brilliant, Soft and Manual, each of which has an appointed code with a specific amount of brightness, contrast, color, tint and sharpness to determine the color tone. Code decision is designated depending on the mode, based on the address installed within micom (1) .
Table 1 bright contrast color tint sharpness 201~96~ `
Standard 31 39 32 34 33 Dark 15 18 15 20 17 Brilliant 45 50 48 52 56 Soft 24 32 28 35 28 Manual x x x x x In the above table, X is an example of optionally designated step. When a news program is on television, stand type is selected by remote controller (3).
Then micom(1) receiving control signal, designates the output address of D/A converting unit (17) for control signal having above amount of brightness, contrast, color phase and packing as O, A0, A1, A2, A3 Table 2 ¦X¦X¦X~1¦0¦D5~D4¦D3¦D2lD1¦DOA3 A2¦Al~AO¦O¦
Once a output part is designated, said micom (1) designates output step of PWM signal. Supposing that brightness control signal level for standard mode is designated as middle level, 31th step among 64 steps in said micom(1), the data code "011111" is outputted through data terminal (D).
If contrast cortrol signal level is designated as 39th step, data code "100111" is outputted. If color control signal level and tint control signal level are designated as 32nd and 34th respectively, data code "100000" and "100010" are respectively outputted.
In such ways, individual step for dark, bright, soft and manual type is designated and the manul type is designed to adjust the features of color tone depending on the optional selection of watchers.
Above-selected mode data together wich control signal outputted through clock terminal (CL) and enable terminal (CE)of micom (1), is sequently entered through data terminal (D) into said D/A converting unit (17).
4.19MHZ of signal generated by oscillator (Z) is outputted at Xout of said micom (1) and then inputted to clock drive~19) of D/A
converting unit (17) through buffer (16).
Then said IM bus interface unit (18) of said D/A converting unit (17) applies a series of incoming step data into 8 bit converter(20).
Said 8 bit converter (20) oscillates an appointed step data to 4.19 MHZ of signal inputted through clock driver (19) and converts it into PWM signal.
Said converted PWM signal is outputted to each Xout. Namely 8 bit converter (20) of said D/A converting unit (17) converts the left side of output as a step designated by micom (1) among 64 steps into PWM and outputs it through buffer.
For example, assuming that bright contol signal level for standard type is assigned as step 31, byte data code "011111" is converted into PWM signal and outputted.
Thereafter, low-pass band filter unit (22) is filtering the PWM
signal from 8 bit D/A converter (17) to output pulsating current to be entered in croma signal unit (23).
Going through above process, while a designated step of contrast, 2014~62 -color, tint, sharpness for standard type is outputted, an amended signal is outputted onto the screen.
Depending on a watcher~s preference, the band of field signal to be displayed on the screen can be selected to show more realistic picture.
Sound selection processing is arranged to respond to the circumstance of broadcast program as shown in Figure 3.
As soon as audio program key on remote controller (3) is touched in ord~r, the micom (1) performs a main program pursuant to micro program sequence. Through its audio signal swing port (ADl) (AD2), it is changed into 4 kinds of signals ; high-high signal selecting low-pass band (28) of equalizing circuit (25), high-low signal selecting medium pass band (27), low-high signal selecting medium high pass band (29), low-low signal selecting high-pass band (26).
In accordance with a signal from the audio signal swing port (ADl) (AD2) of said micom (l), an audio signal of each frequency band fixed at equalizing circuit (25) is selected while being applied to relevant chip of audio signal switching IC circuit (24).
Explaining 4 kinds of signals at this stage by each step, when music is broadcasted such as in show program, once a watcher pushs the audio program key of the remote controller (3), a high-high signal selected by program performed by micom(l) is applied through the audio signal swing port (AD1) (AD2) into the audio signal switching IC circuit (24), which chip-selects so as to transmit a audio signal of the low-pass band (28) to left and right speakers (not shown in figure). By outputting an audio signal stressing low-pass band (28), music full of presence in the show program can be catched.
On the other band, at the same time of outputting a high-high signal through the audio signal swing port (AD1) (AD2) of the micom (1), DOS character corresponding to audio signal is outputted to display the charaters "music" on the screen.
If the TV program is changed into a movie, when the watcher pushes the audio program key once more, a high-high signal is outputted through the audio signal swing port (AD1) (AD2) and applied to said audio signal switching IC circuit (24).
Then the low-passe band (28) of audio signal added to music is stopped by the audio signal switching IC circuit (24) and converted into a medium pass band (27) of audio signal, thus providing a sound full of ambience suitable to the televised movie and displaying DOS "
movie" on the screen.
Supposing that a drama program is televised, once one presses the audio program key once more, totalling three times, the audio signal swing port (AD1) and (AD2) apply low signal and high signal respectively to audio switching IC circuit (24).
Upon receiving a low-high signal, said switching IC circuit (24) selects medium to high-pass band (29) of audio signal and forwards it to a speaker, at the same time supplying a sound appropriate to drama and displaying DOS "drama" on the screen.
Assuming that a news program is televised, if one presses again the audio program key of a remote controller (3) which was previously arranged for drama, the low-high signal is converted into a low-low signal at the audio signal swing port (AD1) (AD2) of micom (1) and applied to the audio switching IC circuit (24).
2014~62 , At the same time, high-pass band of audio signal applied to the switching IC circuit (24) is selected and outputted to a speaker.
And DOS video signal showing what audio signal is presently selected, namely "NEWS" is displayed through (R) (G) (Y) terminal on the screen of a television set.
A television set according to the present invention extends various service functions such as prearranged watching, telephone directory, memory of birthday and anniversary to display the recorded data on the screen on a designated date or previous day, thereby reminding the important dates to watchers.
In addition, in conformity with the contents of bradcost programs such as music, movie, drama, news, sport, a specific color features stressing a suitable color tone therefor can be remotely selected to show a realistic and vivid picture, with regards to a sound signal according with said screen signal according to the contents of broadcast program, a memory device which keeps the mean value of tone color frequency level, successively selects the output, to fit the mood of broadcast program, in order to attain the live and animated sound effeet.
Therefore, this invention is to produce a high-tech television with various service function and automatic selection of audio and video so as to catch the original image.

Audio signal of swing port (AD1, AD2) of said micom(1) is connected to audio signal switching IC circuit (2~), which is then linked to high-pass band (26), medium-pass band (27), low-pass band (28), medium to low pass band (29) of equalizing circuit (25) which is classified by the level of phonetic pressure, and the other end of said band (26-29) is applied by left and right phonetic signals (L1, R1), thereby selecting a sound appropriate to the atmosphere of TV program by audio mode selection key placed on the remote controller (3).
- ~ 20149t~2 The present invention according to above-described composition is operative as follows.
In operating a TV set, as the switch of a remote controller (3) is touched, a remote receiver of micom(1) converts received signals into digital ones which are readable by input-output control unit (2) and inputs them to input-output control unit (2).
Then said input-output control unit inputs interrupt signal (INT) into control processing unit (4) to check the programs stored in operation memory (10-12) through address bus.
In case of receiving no interrupt signal (INT) from input-output control unit (2), in accordance with a periodic signal (INT) generated from syncronous signal generation circuit (6), central processing unit (4) checks EEPROM (12) pursuant to the designated address to output the reserved data.
Supposing that a channel conversion signal is inputted from remote controller (3), central control unit (4) operates EEPROM as above explained, so that central control unit (4) converts the screen display according to said channel conversion signal input from remote controller (3).
When a optional code from remote controller (3) is inputted to micom (1), said micom (1) converts it into a code ruled by central processing unit (4) and creates transmission clock RXCA (receive clock at sio)and its Xout transmits outgoing data RXDA by one byte to input-output control unit (2).
As a data from said micom (1) is inputted to input-ouput control unit (2), interrupt signal is generated to suspend the routine performed by central processing unit (4) and perform receive 20149~2 servlce .
In receiving from micom (1), RTS of input-output control unit(2) to perform service routine of receiving data pursuant to the generated RTS signal, creates receive clock TXCA at micom and receive incoming date TXCA by one byte.
Namely, when input-output control unit (2) has a data transmitted from micom (1), interrupt signal (INT) is automatically produced to receive a data from service routine of central processing unit (4).
At this moment, receive service notifies input-output control unit (2) that is read mode by 92nd address among I/O ports designat-ing input-output control unit and receives data by 90th address.
In transmittal, it notifies input-output control unit (2) that is write mode by 90th address and transmit data by said 90th address.
After such transmitted data is inputted to receiving buffer of said input-output control and all recorded, while syncronizing RXC~
or TXCA, central control unit (4) lets input-output control unit (2) produce RTS, forwarding low-level interrupt signal to micom(1).
In receiving a data from said micom(1), central control unit (4) decides whether to store on RAM or EEPROM of operation memory (10-12) the data recorded on buffer of said input-output control unit (2) and generates vector address to store it through date bus.
Data stored on said operation memory (10-12) through data bus is then inputted by enable signal (CE) of decoder (5) to screen control unit (7). Said central processing unit returns to the step prior to service routine and resumes the suspended rountine.
RAM of said operation memory (10-12), utilizing SRAM with 8 201~62 byte of COOO-DFFF alloted, is used to temporaily store the data readed from input-output control unit (2) or to arrange data by storing altering, deleting or newly entering the entire data EEPROM
of said operation memory (14) with 8K byte of FOOO-FFFF is used to permanently reserve the data to be stored.
When data transmitted through data bus is inputted to said screen control unit (7), the input-output part using AO-A3 address makes access to screen control unit (7).
For exanple, if port AD, H are assigned, port O of said screen control unit (7) is assigned on address line of A0, A1, thereby accessing video RAM (8) subordinate to said screen control unit (7) and having CSR, CSW made of A2-A7 and IQRD, RD & WR decide read or write mode to output R.G.B signal.
Said screen control unit (7) according to this invention, in bit map method, may use video RAM (8) up to 128K byte.
Screen control unit (7) constitutes an incencitive of R.G.B.
output by comparing vertical or horizontal signal, and switches TV signals by means of VS signal.
Said video RAM (8) allots 32K byte per each screen and regards it as one page. Page 0 is for read and write of data to be actually displayed, while page 1 is to store the style of charater received from central control unit (4) at the beginning of program.
Character or picture type of RGB signal is outputted through internal data bus by a code designating the color on page 0 to display the screen.
Flowchart in Figure 4 further describes the above process in more details.
As a data is inputted by remote control, said screen control - 2014~62 unit (7) makes YS signal high, cuts off the signal of screen control unit (7) to be outputted to a TV set, and initiates said central processing unit (4) and operation memory (10-12). It then sets the initial value of RAM of operation memory (11) and retrieves whether system is normal.
In case that the program is found abnormal, it cuts off the program, while if it is normal and any assigned program exists, it turns on the power of television and performs the next operation.
Namely, upon receiving remote control signal, central control unit~4) reads mode at RAM of operation memory (10-12), branches off register according to the mode value and turns on the main power.
Thereafter, central control unit (4) judges TV/AV mode, reserved watching mode, telephone directory memory mode, birthday or anniversary reservation mode.
If a selected mode is TV/AV mode, after completing the process shown in Figure 4 (D), it checks whether it is reserved and records the altered data entered from remote controller (3) or outputs the stored data.
Figure 4(E) (F) shows the procedure of altering and reserving the channel data stored on EEPROM of operation memory (12).
Numeric channel data includes data such as telephone number, birthday, anniversary depending on the mode selection.
Accordingly, once the state of system is confirmed in the initial routine stage and a reserved data is retrieved, entered data is outputted through respective routine, as shown in Figures (E) (F) and displayed on CRT ( 15) through said screen control unit (7) and switching part (14).
- - 2Q14~62 For example, Figure 4(G) shows the program for displaying the data of birthday or anniversary. Once the appointed data is read from data address of EEPROM, the data is outputted at micom (1) through central control unit (4) and input-output control ur.it (2).
Accordingly, message data is displayed as many as the number of data by message key, micom(1) comes melody unit (1~) into action, and screen data is displayed on CRT(15) through said screen control unit (7) and switching part (14).
In case of having the displayed data on he screen without interruption, RAM of said operation memory ~11) is read as shown in Figure 4 (H).
According to above-described process, this invention provides multi-function such as reserved watching, memory and display of birthday, telephone number and anniversary. As shown in Figure 2, it also provides video selection processing to stress a specific color tone of screen by selecting as hard or soft the color corresponding to the mode of broadcast program (sports, news, drama, music, movies). Data program mode is divided into Standard, Dark, Brilliant, Soft and Manual, each of which has an appointed code with a specific amount of brightness, contrast, color, tint and sharpness to determine the color tone. Code decision is designated depending on the mode, based on the address installed within micom (1) .
Table 1 bright contrast color tint sharpness 201~96~ `
Standard 31 39 32 34 33 Dark 15 18 15 20 17 Brilliant 45 50 48 52 56 Soft 24 32 28 35 28 Manual x x x x x In the above table, X is an example of optionally designated step. When a news program is on television, stand type is selected by remote controller (3).
Then micom(1) receiving control signal, designates the output address of D/A converting unit (17) for control signal having above amount of brightness, contrast, color phase and packing as O, A0, A1, A2, A3 Table 2 ¦X¦X¦X~1¦0¦D5~D4¦D3¦D2lD1¦DOA3 A2¦Al~AO¦O¦
Once a output part is designated, said micom (1) designates output step of PWM signal. Supposing that brightness control signal level for standard mode is designated as middle level, 31th step among 64 steps in said micom(1), the data code "011111" is outputted through data terminal (D).
If contrast cortrol signal level is designated as 39th step, data code "100111" is outputted. If color control signal level and tint control signal level are designated as 32nd and 34th respectively, data code "100000" and "100010" are respectively outputted.
In such ways, individual step for dark, bright, soft and manual type is designated and the manul type is designed to adjust the features of color tone depending on the optional selection of watchers.
Above-selected mode data together wich control signal outputted through clock terminal (CL) and enable terminal (CE)of micom (1), is sequently entered through data terminal (D) into said D/A converting unit (17).
4.19MHZ of signal generated by oscillator (Z) is outputted at Xout of said micom (1) and then inputted to clock drive~19) of D/A
converting unit (17) through buffer (16).
Then said IM bus interface unit (18) of said D/A converting unit (17) applies a series of incoming step data into 8 bit converter(20).
Said 8 bit converter (20) oscillates an appointed step data to 4.19 MHZ of signal inputted through clock driver (19) and converts it into PWM signal.
Said converted PWM signal is outputted to each Xout. Namely 8 bit converter (20) of said D/A converting unit (17) converts the left side of output as a step designated by micom (1) among 64 steps into PWM and outputs it through buffer.
For example, assuming that bright contol signal level for standard type is assigned as step 31, byte data code "011111" is converted into PWM signal and outputted.
Thereafter, low-pass band filter unit (22) is filtering the PWM
signal from 8 bit D/A converter (17) to output pulsating current to be entered in croma signal unit (23).
Going through above process, while a designated step of contrast, 2014~62 -color, tint, sharpness for standard type is outputted, an amended signal is outputted onto the screen.
Depending on a watcher~s preference, the band of field signal to be displayed on the screen can be selected to show more realistic picture.
Sound selection processing is arranged to respond to the circumstance of broadcast program as shown in Figure 3.
As soon as audio program key on remote controller (3) is touched in ord~r, the micom (1) performs a main program pursuant to micro program sequence. Through its audio signal swing port (ADl) (AD2), it is changed into 4 kinds of signals ; high-high signal selecting low-pass band (28) of equalizing circuit (25), high-low signal selecting medium pass band (27), low-high signal selecting medium high pass band (29), low-low signal selecting high-pass band (26).
In accordance with a signal from the audio signal swing port (ADl) (AD2) of said micom (l), an audio signal of each frequency band fixed at equalizing circuit (25) is selected while being applied to relevant chip of audio signal switching IC circuit (24).
Explaining 4 kinds of signals at this stage by each step, when music is broadcasted such as in show program, once a watcher pushs the audio program key of the remote controller (3), a high-high signal selected by program performed by micom(l) is applied through the audio signal swing port (AD1) (AD2) into the audio signal switching IC circuit (24), which chip-selects so as to transmit a audio signal of the low-pass band (28) to left and right speakers (not shown in figure). By outputting an audio signal stressing low-pass band (28), music full of presence in the show program can be catched.
On the other band, at the same time of outputting a high-high signal through the audio signal swing port (AD1) (AD2) of the micom (1), DOS character corresponding to audio signal is outputted to display the charaters "music" on the screen.
If the TV program is changed into a movie, when the watcher pushes the audio program key once more, a high-high signal is outputted through the audio signal swing port (AD1) (AD2) and applied to said audio signal switching IC circuit (24).
Then the low-passe band (28) of audio signal added to music is stopped by the audio signal switching IC circuit (24) and converted into a medium pass band (27) of audio signal, thus providing a sound full of ambience suitable to the televised movie and displaying DOS "
movie" on the screen.
Supposing that a drama program is televised, once one presses the audio program key once more, totalling three times, the audio signal swing port (AD1) and (AD2) apply low signal and high signal respectively to audio switching IC circuit (24).
Upon receiving a low-high signal, said switching IC circuit (24) selects medium to high-pass band (29) of audio signal and forwards it to a speaker, at the same time supplying a sound appropriate to drama and displaying DOS "drama" on the screen.
Assuming that a news program is televised, if one presses again the audio program key of a remote controller (3) which was previously arranged for drama, the low-high signal is converted into a low-low signal at the audio signal swing port (AD1) (AD2) of micom (1) and applied to the audio switching IC circuit (24).
2014~62 , At the same time, high-pass band of audio signal applied to the switching IC circuit (24) is selected and outputted to a speaker.
And DOS video signal showing what audio signal is presently selected, namely "NEWS" is displayed through (R) (G) (Y) terminal on the screen of a television set.
A television set according to the present invention extends various service functions such as prearranged watching, telephone directory, memory of birthday and anniversary to display the recorded data on the screen on a designated date or previous day, thereby reminding the important dates to watchers.
In addition, in conformity with the contents of bradcost programs such as music, movie, drama, news, sport, a specific color features stressing a suitable color tone therefor can be remotely selected to show a realistic and vivid picture, with regards to a sound signal according with said screen signal according to the contents of broadcast program, a memory device which keeps the mean value of tone color frequency level, successively selects the output, to fit the mood of broadcast program, in order to attain the live and animated sound effeet.
Therefore, this invention is to produce a high-tech television with various service function and automatic selection of audio and video so as to catch the original image.
