According to the closed-caption broadcasting method and apparatus, character information and control information are inputted, and a control code of 2 words and a character code of 2 words including a syllable character completion type code are produced. The control code is obtained by combining the control information with a mode control bit and a parity bit, and the character code is obtained by combining the character information with a mode control bit and a parity bit. A digital-modulated caption signal is produced by inputting the control code and the character code, and is coded on a scanning line which does not affect a television video signal to be transmitted.

Abstract: A closed-caption broadcasting and receiving method and apparatus. According to the closed-caption broadcasting method and apparatus, additional information is inputted and the input of word information is checked.

Thereafter, character information and control information of the selected information are inputted. A control code of 2 words is obtained by combining the control information with a mode control bit and a parity bit, and the character code of 2 words including a syllable character completion type code is obtained by combining the character information with a mode control bit and a parity bit. A digital-modulated caption signal is produced by inputting the control code and the character code, and is coded in a scanning line which does not affect a television video signal to be transmitted.

Abstract: A digital AGC circuit is provided which includes an A/D converter, an AGC gate pulse generator and a TOP voltage controller. The A/D converter converts a video signal clamped to a reference level into digital data having a voltage between a predetermined reference voltage and a TOP voltage. The AGC gate pulse generator generates an AGC gate pulse for detecting a pedestal level region of the video signal, according to vertical and horizontal synchronous signals. The TOP voltage controller controls the TOP voltage of the A/D converter on the basis of a sample value extracted from the output of the A/D converter and a sync tip value of a standard signal, while the AGC gate pulse generated by the AGC gate pulse generator is enabled. All circuits but the low pass filter are digital circuits, so a special analog AGC IC is not needed. AGC is performed by controlling the TOP voltage of the A/D converter, thereby accomplishing an accurate AGC.

Abstract: A video cassette recorder (VCR) is provided with an interface with a telephone jack and a telephone so as to function as an automatic telephone answering machine and as an telephone directory for dialing telephone numbers selected by a user from a list provided via an on-screen display. When an incoming call is received via the telephone jack, a controller determines if the telephone has not been answered within a predetermined amount of time. When the predetermined amount of time lapses without pickup, the VCR records a message from the incoming caller. The telephone number of the incoming caller is also recorded. In the telephone directory mode of operation, a user inputs commands via a key input to select a name and corresponding telephone number from an on-screen display of stored telephone number data and corresponding name data. A controller inside the VCR then causes the selected number to be automatically dialed.
