Abstract

PURPOSE:To improve operability of the television set by reading out data stored in a memory circuit at the time of turning on a power source again, and setting a control state of various functions. CONSTITUTION:In the case of an input from a regular power source driving control input circuit 2, a power source driving circuit 3 becomes a driving state by a data processing circuit 8. Simultaneously, control data of the circuit 3, a voltage control circuit 4, a video control circuit 5, an audio control circuit 6, and an additional function control circuit 7 are read out of a memory circuit 9, the circuit becomes a state immediately before it becomes a non-driven state. Also, in the case a specific control instruction is inputted from the input circuit 2, the circuit 3 is driven by a rewritable data processing circuit 10, and simultaneously, the control data of the circuits 3, 4, 5, 6 and 7 are read out of a memory circuit 11. As a result, by a specific key input, the television set is set to a driving state from a non-driven state, and simultaneously, a control state of various functions can always be set to an arbitrary state set in advance by a user, and operability is improved.

2. Description of the Related Art A conventional apparatus stores video function control data and audio function control data which have been arbitrarily set in advance, and when the television receiver is normally driven, the video function control data or A method of setting the voice function control data to the arbitrary setting state is introduced in page 74 of the special issue of television technology, special issue, October 1988.

[0003]

In the above-mentioned prior art, there is no mention of the use of the various function control data arbitrarily set in advance when the television receiver changes from the non-driving state to the driving state. When the user turns on the television receiver, the various function control data are stored immediately before the power is cut off, and the user newly controls various functions such as the receiving channel, the volume, and the brightness of the screen. You have to set the data.

An object of the present invention is to drive a specific television receiver in which the various function control data desired by the user is constant (for example, the television receiver is changed from the non-driving state to the driving state for the first time every morning. In this case, the television receiver is switched from the non-driving state to the driving state by a specific key input, and at the same time, the control states of the above-mentioned various functions are always set by the user in advance instead of being stored in the state immediately before power-off It is to make it a state.

[0005]

In order to achieve the above object, a rewritable first memory circuit for storing control data of the above various functions immediately before power-off when a normal television receiver is driven. When the power is turned on again, the data stored in the first memory circuit is read, and the first data processing circuit for setting the control state of the various functions to the state immediately before the power is shut off When driven, when the specific television receiver is driven (when specific data is input from the input circuit), the power supply driving circuit is set to the driving state and simultaneously stored in the first memory circuit. Regardless of the stored data, read the data stored in the rewritable second memory circuit for the user to set the control data for the above various functions in advance. To, in which so as to drive the television receiver by the second data processing circuit for a state in which pre-user has arbitrarily set the control status of the various functions.

[0006]

When the specific television receiver is driven (for example, when the television receiver is switched from the non-driving state to the driving state for the first time every morning), the television receiver is driven from the non-driving state by the specific key input. At the same time, by setting the control states of the various functions by reading and setting the data stored in the second memory circuit, regardless of the data stored in the first memory circuit, It becomes possible for the user to set the state arbitrarily.
