Hereinafter, an apparatus for displaying caller information of the present invention on a television will be described in detail with reference to the accompanying drawings.

The apparatus of the present invention is for receiving and displaying caller information provided by a telecommunication construction through a television, and is composed of a caller information input unit and a caller information display unit. The caller information input unit receives the caller information transmitted from the communication construction, extracts the contents, and transmits the extracted data, and the caller information display unit displays the caller information transmitted from the caller information input unit on the screen of the television. do. The method of displaying on the screen is performed by using an OSD function. In this case, the caller information is mixed with a signal of a VCR or a cable TV as an external input.

First, the caller information provided by the communication construction will be described with reference to FIG. 1. The caller information service is a service that sends the subscriber's subscriber number, subscriber's name, date, time, etc. to the receiver when the call comes in. Before the call, the caller sends the information between the first and second ringtones. Provide caller information while in a call.

In the pre-call ON-hook state, a ringing signal first rings and then FSK modulation carries a bundle of data. The data bundle contains message bytes, chunk bytes of total information, and checksum bytes for error detection. In the data bundle, data such as date, time, subscriber number, name, etc. are transmitted at the same time, and error state is determined by using checksum bytes. If there is no error, caller information is extracted and stored. The storage of caller information is stored in a memory device such as an EEP-ROM. Stored caller information is extracted and sent when necessary.

In the off-hook state during a call, referring to FIG. 2, when a call is received from the outside, the telecommunication construction company sends a CAS signal (440 Hz) signal first before transmitting the FSK (Caller ID Data: caller information) to alert the telephone caller. Notify me of a call. In addition, when the control unit recognizes the CAS signal and sends an ACK ("D" of DTMF), which indicates that data reception is possible, the caller ID DATA is sent as a ratio.

This signal can hurt the caller's ear or cause the external noise to be a transmission error during data transmission, so the MCU inside the receiver controls this to pause the call until all data reception is completed and receives the FSK signal for 500ms. If it fails to do so, it returns to the initial reception state and the response signal does not send data unless it sends an ACK signal.

The present invention basically includes all of the above functions, and further includes a wired / wireless data transmission interface for data transmission with the outside.
