Abstract

본 발명은 메모리 카드를 이용한 기록재생 시스템에 관한 것으로, 특히 A/V 신호의 기록영역과는 별도로 설정된 메모리카드의 기록영역에 타이틀에 관한 정보를 저장하고 이를 이용하여 사용자가 선택적으로 타이틀(Title)을 디스플레이 ON또는 OFF 할 수 있는 타이틀 편집기능을 갖는 기록재생장치 및 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording and reproducing system using a memory card. In particular, information on a title is stored in a recording area of a memory card set separately from the recording area of an A / V signal, and a user selectively uses a title. The present invention relates to a recording / playback apparatus and method having a title editing function that can display ON or OFF.

상기와 같은 본 발명의 메모리 카드를 이용한 기록재생 시스템은 A/V 기록영역과 별도의 타이틀 정보기록 영역을 갖고 사용자의 선택에 의한 타이틀의 시작 및 종료 어드레스와 고유번호 등을 저장 출력하는 메모리 카드와, 시스템 전체를 제어하고 Key 입력수단부를 통한 사용자의 선택신호에 의해 타이틀 설정 및 디스플레이 동작을 ON 또는 OFF 되도록 제어하는 제어수단부와, 상기 제어수단부의 제어에 의해 선택적으로 타이틀 신호를 발생하는 타이틀 발생수단부와, 디지탈 신호로 변환되어진 A/V 신호를 특정 포맷으로 처리하여 출력하는 기록신호 처리수단부와, 상기 기록신호 처리 수단부의 A/V 신호를 메모리 카드의 A/V 기록영역에 저장 출력하는 메모리 컨트롤러와, 상기 메모리 컨트롤러에서 출력되는 A/V 신호를 특정 포맷으로 처리하는 재생신호 처리수단부와, 상기 재생신호 처리수단부의 아나로그 변환되어진 A/V 신호와 상기 타이틀발생수단부의 타이틀 신호를 합성 처리하여 출력하는 영상신호 합성처리부를 포함하여 이루어진다.The recording and reproducing system using the memory card of the present invention as described above comprises a memory card having a title information recording area separate from the A / V recording area and storing and outputting a start and end address and a unique number of a title according to a user's selection; A control means for controlling the entire system and turning on or off a title setting and display operation by a user's selection signal through a key input means, and a title for generating a title signal selectively under the control of the control means. Storing and outputting an A / V signal in the A / V recording area of the memory card; and a recording signal processing means for processing the A / V signal converted into a digital signal in a specific format. And a reproduction signal for processing the A / V signal output from the memory controller in a specific format. Comprises a risu end and the video signal processing section and outputting the synthesized composite processing the reproduced signal processing means portion analogue conversion A / V signals and the titles of said signal means title been generated.

제1도는 본 발명의 메모리 카드를 이용한 기록재생 장치의 구성블럭도.1 is a block diagram of a recording and reproducing apparatus using the memory card of the present invention.

Claims

A recording and reproducing apparatus using a memory card, comprising: a memory card having a title information recording area separate from an A / V recording area and storing and outputting a start and end address and a unique number of a title according to a user's selection; A control means unit for controlling the title setting and display operation to be turned on or off by a user's selection signal through the key input means unit, a title generating means unit for selectively generating a title signal under the control of the control means unit; A recording signal processing means for processing and outputting the A / V signal converted into a digital signal in a specific format, a memory controller for storing and outputting the A / V signal in the A / V recording area of the memory card; A reproduction signal processing unit for processing the A / V signal output from the memory controller in a specific format; And a video signal synthesizing processing unit for synthesizing and outputting the analog-converted A / V signal of the reproduction signal processing unit and the title signal of the title generating unit.

In recording using a memory card, when a title mix mode signal of the user's selection is input during recording of an A / V signal, the current address is designated as the start address of the set title and stored in the title recording information area of the memory card. And a second step of designating the current address as the end address of the set title and storing it in the title information recording area of the memory card when the title mix mode end signal input by the user is input again. A recording and reproducing method having a title editing function.

In a playback operation using a memory card, if a title ON signal is selected by a user during playback of an A / V signal, the first step of reading information of the title in the title information recording area, and up to the start address of the title A second step of outputting the title when the reproduction operation is advanced; a third step of stopping the display of the title when a title OFF signal of the user's selection is input during display of the title; And a fourth step of turning off the title when the reproduction operation proceeds to the end address.
