In the wireless access mode, the caller ID signal is decoded by an external caller ID receiving device with a wireless transmitting function, and then converted into a wireless remote control signal in a specific format and sent to a wireless remote control receiving circuit of the television for processing.

When the wired access method is adopted, the television has a telephone line jack, and the caller ID signal transmitted from the telephone line is decoded by the built-in receiving circuit of the television, and the television subtitle display control circuit is sent as a result.

Under the control of the caller ID data processing included in the TV remote control signal processing program, the subtitle display control circuit can display the caller number, call time and date, caller name, outgoing, confidentiality in characters and graphics anywhere on the screen. , Message, call waiting and other information, if necessary, it also allows operations such as storing, checking, and deleting incoming call information.

The external caller ID receiving device used by the TV set has the same modulation method and signal carrier of the transmitted signal as the TV remote control; the signal code contains signal heads and identification codes that characterize the characteristics of the caller ID signal. Television remote control signals are confusing.

The invention is simple and reasonable, so that the television can easily receive and display the caller information transmitted by the telephone system to the telephone terminal at a low cost, can display the caller number on the TV screen, and can play this to a greater extent. Convenience of telecommunication service functions ... If you do not want to answer the phone, you will not answer it. The children's phone will let the children answer, and the guest's phone will allow the guests to answer ... it feels calm and free.

Examples

As shown in Figure 2.1, the TV input signals (RF, AV) of the TV still maintain the original connection side The caller ID signal is connected to the TV wirelessly or wired. The TV remote control signal processing program includes a process for identifying and receiving caller ID data in a specific format. It can handle wired or wireless access to the TV. The caller ID information of the handset; the TV's subtitle display control circuit (0 SDC) turns the received caller ID information into subtitles and displays it on the TV screen together with the currently playing TV image.

As shown in Fig. 2.2, Fig. 2.4, Fig. 2.5, and Fig. 2.6, when the wireless access method is adopted, the television receives the caller ID signal encoded by a specific format from an external caller ID receiving device through a wireless remote control channel. Add the processing of caller ID signal to the remote control signal processing program (see Figure 2.4), which is responsible for decoding, converting, storing, retrieving, displaying and outputting the caller ID signal. If necessary, you can also check the recent caller ID information. The TV hardware does not need to be modified, as long as the existing TV remote signal processor program is added to the caller ID signal processing process: After receiving a valid signal to make a judgment, if it is a caller ID signal, Enter the corresponding caller ID processing process. If it is a normal remote control signal, the normal remote control signal processing is performed (see Figure 2.4). The external caller ID receiving and decoding device with wireless transmitting function, its telephone line interface circuit and decoder adopt the existing universal standard mature circuit, and the microprocessor can also have multiple options. It is required to complete the basic caller ID in addition to Function (LCD display, storage, search, delete, call back, etc.) In addition to controlling the wireless transmission interface, the caller ID content can be transmitted in a specific signal format (see Figure 2.5, Figure 2.6). The transmitted signal uses the same carrier wave as the TV remote control signal and is modulated in the same way, and its signal code contains a signal header and a feature identification code that characterizes the caller ID signal (see Figure 2.6).

As shown in Figure 2.3 and Figure 2.4, when the wired access method is used, the TV is directly connected to the telephone line, and the receiver has a receiving circuit for the caller ID signal (see Figure 2.3). The caller ID receiving and decoding circuit is placed in the TV. The telephone line interface circuit and the decoder adopt the existing universal standard mature circuit. The microprocessor can also have multiple options. It is required to complete the basic caller ID function in addition to It can also send the received caller ID content to the TV's subtitle display control circuit for output. Since the core of the subtitle control circuit of a television is usually a remote control receiving processor, it is also necessary to add a process of embedding the caller ID signal in the program of the remote control signal processor of the television (see Figure 2.4).

The devices and circuits used in the overall technical solution are standard devices and circuits that are widely used today-caller ID receiving and decoding circuits are quite mature, and even have monolithic integrated circuits (such as EMC of Taiwan Elan Electronics 7 8 8 1 1 etc.) and standard finished modules are provided. The remote control circuit and the caption display control circuit of the TV are also very mature and fixed; usually the remote control receiving processor of the TV is a part of the caption display control circuit. Since the TV can easily receive caller ID information, it is also easy to do this information. Further processing operations, such as storing, searching, deleting, and so on.

It can be seen that the patent solution provides a specific method for realizing the display of a calling number on a television at the lowest cost, and the method does not affect the TV picture quality at all. It is worth emphasizing that if the TV is used to display the calling number of a TV set by using a wireless access method, there is no need to change the existing TV line, nor will it increase its hardware cost. It is a shortcut to upgrade TV product functions.
