KR970050943A - Video tape recognition method and device by voice signal - Google Patents

Abstract

The present invention detects an audio signal of an initial predetermined section of a rented videotape and stores it in a memory, and when a new videotape is viewed, comparing the data stored in the memory with the audio signal of a corresponding section of a new videotape. It is an object of the present invention to provide a method and apparatus for recognizing a video tape using a voice signal to determine whether the tape is recognized by a user.

A method of the present invention for achieving the above object includes a VCR status searching process for searching whether a tape inserted in a deck is in a playback mode when a television receiver and a VCR are driven; When the tape inserted in the deck is in the playback mode, the audio signal is stored in the memory for a certain period after a predetermined time, and when a new tape is played, it is compared to the previously watched tape. Characterized in that made.

Claims (3)

A VCR status search process for searching whether the tape inserted in the deck is in the playback mode when the television receiver and the VCR are driven; When the tape inserted in the deck is in the playback mode, the audio signal is stored in the memory for a certain period after a predetermined time, and when a new tape is played, it is compared to the previously watched tape. A video tape recognition method using an audio signal, characterized in that made. 2. The method of claim 1, wherein the viewing decision process comprises: detecting a sound signal after a predetermined time period when the tape inserted into the deck is in a play mode; Comparing the detected voice signal with the stored voice signal to determine whether they match; Notifying the user of the previously watched tape when the detected voice signal and the stored voice signal are the same; And storing the voice signal for a predetermined period when the detected voice signal and the stored voice signal are not the same. A microprocessor which senses an input key for searching whether the tape inserted by the user through the remote controller is a previously watched tape and controls each part of the system of the VCR; A timer for counting a time set when selecting a play mode according to the control of the microprocessor; A voice signal detector for detecting a voice reproduction signal according to the control of the microprocessor which senses that the predetermined time has elapsed from the timer; An analog / digital converter converting the analog voice signal detected by the voice signal detector into a digital signal and outputting the digital signal to a microprocessor; A data recording / reading control section for recording and reading the audio data output from the analog / digital conversion section in accordance with a control signal from the microprocessor; A memory for storing or reading out audio data under the control of the data recording / reading control section; A data comparison section for comparing data obtained from the analog / digital conversion section with read data from the data recording / reading control section under the control of the microprocessor; A digital / analog converter for converting a digital control signal output from the microprocessor to an analog signal according to a comparison result of the data comparator; Recognizing a video tape by an audio signal comprising an OSD driver for reading out a corresponding character for display to a user from an OSD font ROM according to a control signal output from the digital / analog converter and outputting the corresponding character to an image signal processing system. Device. ※ Note: The disclosure is based on the initial application.
