Abstract

PURPOSE: An automatic TV on/off system is provided to encode a signal controlling the TV to video/audio signals of a main carrier for transmission using an encoder, and to decode signals using a decoder internally or externally mounted on the TV, so as to provide functions of region discrimination, TV on/off. code changing, volume adjusting, and information provision, etc. CONSTITUTION: If a TV is not turned on, the TV is turned on. A channel of the TV is fixed to an emergency broadcasting channel. Contents on emergency are displayed or changed on a caption. A volume of the TV is adjusted to a volume initially selected by a user. Whether an emergency release start code is received is checked. If received, whether a region discrimination code, an individual/group code, and an emergency type code correspond to values initially inputted by the user is checked. If so, an emergency release end code is received is checked. If so, a general broadcasting mode, that is a TV state prior to the emergency broadcasting, is returned.

Description

TV automatic on / off system {.}

Conventionally, in order to turn on / off the remote TV, etc. from a broadcasting station, a radio wave other than the main carrier (MAIN CARRIER) is transmitted to operate a relay such as a TV to turn on / off the TV.

There were many problems in practical use due to the problem of antenna location adjustment and radio wave reception confirmation in basement of the blind spot.

This system

The video / audio signal of MAIN CARRIER of a broadcasting station is superimposed on an encoder and sent out by an encoder.

This system has a function to decode the signal with a decoder built-in / external to a TV / VCR, etc. to turn on / off the area, change the station number, adjust the volume, and provide information.

Other signals instead of audio or video signals

(As a signal used to control the TV with ancillary signal Ancillary DATA)

Detects the power of the TV and turns ON when the TV is ON, and turns ON when the TV is OFF.

Method to use as a signal to control the TV

Area code (e.g., postal code, line separator area code, etc.),

Individual / Group Code (e.g. Social Security Number, Public Official Number, etc.)

Method to control TV or provide discrimination information by selecting data by region or individual / group by using

The receiver inputs the required region code, emergency type code, and volume level into the decoder in advance to select and view the selected information.

Detect the ON / OFF status of the TV, turn the TV ON

The flow of disaster broadcasting data is as follows.

Normal broadcast mode refers to the TV status before the disaster warning broadcast. That is, the viewer is watching another channel or the TV is turned off.

The disaster broadcasting start inspection checks whether or not a disaster alarm has been issued in the following order. If the condition is satisfied, the system switches to the disaster broadcasting mode and maintains the current TV status if it is not satisfied.

Disaster Broadcasting ModeIs Do the following:

If the TV is not powered on, turn on the TV.

Fix the TV viewing channel to the disaster broadcasting channel.

Display or change alarm contents in subtitles.

Adjust the TV volume to the volume you initially selected.

The disaster broadcasting end inspection checks whether the disaster alarm has been released in the following order, and when the disaster alarm release condition is satisfied, it switches to the TV state (general broadcasting mode) before the disaster broadcasting.

In the simplest structure, the tuner selects only the channel that broadcasts the disaster, and performs the subtitle function normally. When the disaster code is received, the disaster broadcast is performed. If the TV is turned on, adjust the user's preset volume. If the TV is turned off, turn on the TV, adjust the user's preset volume, and notify them of the disaster.

The simplest structure, the lowest cost, and easy to implement

The user's satisfaction is lowered because the subtitle function is provided only to the disaster broadcasting channel.

In the design, the user selects the desired channel and adds the function to view the subtitles provided by the broadcasting channel.

It is relatively inexpensive due to its simple structure, and its implementation is easy. However, when the user is not watching the disaster broadcasting channel, it cannot notify the disaster alert.

By using two tuners, the user can select the desired channel to utilize the closed captioning function. The other channel is fixed to the channel that broadcasts the disaster, and when the disaster contents matching the user's input condition are received, the contents are subtitled. Users can be informed with If the disaster is received, but the TV is turned off, turn on the TV to notify the contents of the disaster, and when the user is watching another channel, switch to the disaster broadcasting channel to notify the contents of the disaster, and the disaster broadcasting ends. When it does, return to the original TV state.

It is efficient to inform the user of the disaster and provides the function of closed captioning, so the user's satisfaction with the system is very high, but two tuners are required, resulting in high system implementation costs.
