In order to incorporate this principle there is a need for technological changes in the existing television. Therefore the circuitry of the known television is changed.
It is the primary object of invention to invent a television which incorporates satellite radio, terrestrial radio and data broadcasting.
It is another object of invention to invent a television which incorporates satellite radio, terrestrial radio and data which results in saving lots of money.
It is another object of invention to invent a television which incorporates satellite radio, terrestrial radio and data which incorporate novel technology.

The specialty of the invention is the incorporation of satellite radio, terrestrial radio and data, and the facility to switch ON/OFF the power supply which is given to the radio sections, video section and CRT filament section in a television.
The satellite radio is used to hear the different chaimels provided by the satellite radio stations . It is incorporate in a television to hear the excellent audio quality.
The terrestrial radio is used to hear the different channels provided by the terrestrial radio broadcasting. It is incorporate in a television to hear the audio.
The sound signals in a television are FM ( Frequency Modulated). The quality of the television sound is normally good when compared to radio and monotape recorders . But today the television has an excellent sound effect (i.e.) preference or adjustments of Bass, Treble, AVL ( Auto Volume Leveler ) and equalizer effects . The televisions are having more than one speaker . In addition, for excellent bass results , subwoofer for rich bass is also attached . The power of the audio output is about 40watts, 60 watts ,100 watts ,200 watts ,350 watts etc.,.. The television is having a stereo sound effect . Therefore the sound effect in a television is nearly equal to Hi-If (High Fidelity) music system . The above mentioned sound effects in a television are of excellent quality.
If the television is switched ON, the user can select either television or satellite radio or terrestrial radio or data (i.e.) depending on the preference of the user.

But the power supply which is given to the remote section and the sound section is always ON, when the television is switched ON and the user cannot switch OFF those sections.
The user can opt for
1) Operation of Television set or
2) Operation of Satellite radio or
3) Operation of Terrestrial radio or
4) Operation of Data, when the television set is switched ON.
1) If the user opts for the operation of Television, the satellite
radio, terrestrial radio and data does not function automatically ( the power
supply given to satellite radio, terrestrial radio and data is automatically
switched OFF).
When the user watching the video and hearing to audio of television, he can switch OFF the power supply given to the video section and the CRT filament section by pressing a key , named eg: 'video' and can listen to audio only. The power consumption upto 60% can be saved fiow the total consumption of power of the television set when the user presses the 'video' key which is used to switch OFF the video section. Also when the user can make use of the 'video' key and switch ON the video section to watch the video on the television screen.
2) If the user opts for the operation of Satellite radio, the television
does not function automatically ( the tuning voltage of the television tuner is
switched OFF by a switching and the I.F signal of the television tuner is cut off,
power supply given to terrestrial radio and data is cut off by a switching).

3) If the user opts for the operation of Terrestrial radio, the television, satellite radio and data does not function automatically ( the tuning voltage of the television tuner is switched OFF by a switching and the LF signal of the television tuner is cut off, power supply given to satellite radio and data is cut off by a switching).
4 ) If the user opts for the operation of Data, the television, satellite radio and terrestrial radio does not function automatically ( the tuning voltage of the television tuner is switched OFF by a switching and the LF signal of the television tuner is cut off and the sound section in the television are switched 'OFF automatically, power supply given to satellite radio and terrestrial radio is cut off by a switching, while the operation of data broadcasting the video section can be switched 'ON* or 'OFF' using the 'video' key).
The display of features of the satellite radio, terrestrial radio is achieved in a television set by adopting two possibilities either
a.) By displaying the features on the television screen or
b ) By displaying the features on the LCD screen.
a ) The features of the satellite radio or terrestrial radio can be displayed on the television screen. The power supply which is given to the video section and the CRT filament section is switched ON automatic at a time-When the features of the satellite radio or terrestrial radio are arranged to be displayed on the television screen, the switching circuit ( CTL 2 ) is not needed. The user can select the features of the satellite radio or terrestrial radio viz. frequency tuning, volume control etc.,. which are displayed on the television screen. After selecting the .features of the satellite radio or terrestrial radio, the user can switch OFF by pressing the key 'video' [ i.e. switching OFF the power supply which is given to the video section ( CTL 3) and the CRT filament

section ( CTL 4 ) ]. Now the user can listen to the satellite radio or terrestrial radio. If necessary, the user can again switch on the key Video' and select the features of the satellite radio or terrestrial radio and then switch OFF. Therefore the user can save the power supply nearly 60%. And the life of the components of the video section of the television set viz. LOT, IC's, Transistors, CRT etc.,. is maintained.
b ) The LCD can be fixed with the television set on top or bottom of the television screen. While operating the LCD, the tuning voltage of the television tuner is automatically 'OFF', the power supply which is given to the video section and the CRT filament section is automatically switched OFF by a switching circuit ( CTL 2 ) and also the user cannot operate the Video' key at the time of functioning of satellite and terrestrial radio. As the LCD is fixed to the television set, a switching circuit ( CTL 2 ) is needed separately to switch ON/OFF the operations of the video section and the CRT filament section at a time, and therefore the user can operate the Video' key at the time of functioning of data broadcasting. The remote section in the television set sends the signals to the LCD section for displaying the features of the satellite radio or terrestrial radio or data which is operated by using the key, named eg: Features. The power supply which is required for the operation of LCD section is obtained fiow the provisions given to the radio sections. The power supply of the radio sections can be arranged separately as shown in fig.(l) or can be obtained from the power supply of the sound section of the television set, when a transformer is properly designed with required Amperes for operating both the radio sections and sound section in the television set.
The CRT and the video section is switched ON/OFF simultaneously at a time by the switching circuit (CTL 2, CTL 3, CTL 4).

If the television is without a remote control facility, the user can select television or satellite radio or terrestrial radio or data using switches manually in the front side or any side of the television.
If the television has a remote control facility, the selection of television or satellite radio or terrestrial radio or data is operated by using the remote control and the facility to switch ON/OFF the power supply which is given to the video section and the CRT filament section by using the remote control.
