Abstract

본 발명은 메모리 카드를 이용한 기록재생 시스템에 관한 것으로, 특히 단위 프로그램의 예약녹화시에 메모리 용량의 부족으로 인한 프로그램 데이타의 유실을 최소화한 메모리 카드를 이용한 예약녹화 방법에 관한 것이다.The present invention relates to a recording and reproducing system using a memory card, and more particularly, to a reservation recording method using a memory card which minimizes the loss of program data due to the lack of memory capacity during the reservation recording of a unit program.

상기와 같은 본 발명의 메모리 카드를 이용한 예약녹화 방법에서 연결녹화 방법은 사용자의 선택에 의한 녹화모드 신호가 입력되면 메모리 카드의 컨트롤 데이타 영역에서 녹화정보를 읽어내는 제1스텝과, 녹화시작 시간이 되면 설정된 메모리영역의 시작 어드레스 부터 A/V 신호를 기록하면서 메모리 영역의 잔량과 녹화 프로그램의 정보량을 비교하는 제2스텝과, 메모리 잔량이 부족하면 현재 할당된 메모리 영역의 끝지점까지 녹화를 수행하고, 비어 있는 다른 메모리 영역의 처음위치로 이동하여 연결녹화를 수행하는 제3스텝과, 상기 초기할당된 메모리와 재할당된 메모리의 연결정보를 컨트롤 데이타 영역에 기록하고, 재할당된 메모리 영역의 잔량과 녹화 프로그램의 정보량을 비교하여 설정된 프로그램의 종료 시점까지 녹화기능을 수행하는 제4스텝을 포함하여 이루어지고 스킵녹화 방법은 사용자의 선택에 의한 녹화모드 신호가 입력되면 녹화할 프로그램의 모드를 판단하는 제1스텝과, 녹화할 프로그램의 데이타량과 설정된 메모리 영역의 잔량을 비교하여 그에 따라 프로그램의 스킵(Skip)비율을 결정하는 제2스텝과, 결정된 데이타 스킵비율에 따라 오디오 데이타가 없는 부분또는 오디오 데이타가 있는 부분의 데이타를 프로그램모드에 따라 다르게 스킵하여 A/V 신호를 기록하는 제3스텝과, 설정된 프로그램의 녹화가 끝나면 현재의 어드레스를 해당 프로그램의 종료 어드레스로 지정하고 녹화동작을 정지하는 제4스텝으로 이루어진다.In the reservation recording method using the memory card of the present invention as described above, the connection recording method includes a first step of reading recording information from a control data area of a memory card when a recording mode signal is input by a user's selection, and a recording start time. When the A / V signal is recorded from the start address of the set memory area, the second step of comparing the remaining amount of the memory area with the amount of information of the recorded program is performed. A third step of performing a connection recording by moving to an initial position of another empty memory area, and recording connection information between the initial allocated memory and the reallocated memory in a control data area and remaining amount of the reallocated memory area; Compares the amount of information with the recorded program and executes the recording function until the end of the set program. The skip recording method includes four steps. When a recording mode signal selected by a user is input, a first step of determining a mode of a program to be recorded is compared with a data amount of a program to be recorded and a remaining amount of the set memory area. Accordingly, the second step of determining the skip ratio of the program and the data of the part without audio data or the part with audio data are skipped differently according to the program mode according to the determined data skip ratio to record the A / V signal. After the recording of the set program is completed, the third step is performed, and the current address is designated as the end address of the corresponding program, and the fourth step of stopping the recording operation.

Claims

In reservation recording using a memory card, a first step of reading recording information from a control data area of a memory card when a recording mode signal selected by a user is input, and A from the start address of the set memory area when the recording start time comes. The second step of comparing the remaining amount of the memory area with the amount of information of the recorded program while recording the / V signal; if the remaining amount of memory is insufficient, recording is performed to the end point of the currently allocated memory area, and the first position of the other empty memory area The third step of performing the connection recording and recording the connection information of the initial reallocated memory and the reallocated memory in the control data area, and compares the remaining amount of the reallocated memory area and the information amount of the recorded program And a fourth step of performing a recording function until the end of the program. Reservation recording method using a memory card.

According to claim 1, If the remaining amount of reallocated memory area is insufficient, the recording function is performed to the end point, and the recording is performed by connecting from the first position of another empty memory area, and the connection information between memories is stored in the internal control data area. A reservation recording method using a memory card, characterized by repeating the storing operation.

In the scheduled recording using a memory card, when a recording mode signal selected by a user is input, the first step of determining a mode of a program to be recorded is compared with the data amount of the program to be recorded and the remaining amount of the set memory area. A second step of determining a skip rate of a program; and a method of recording A / V signals by skipping data of a portion without audio data or a portion with audio data according to a program mode according to the determined data skip ratio. And a fourth step of designating the current address as the end address of the program when the recording of the set program is finished and stopping the recording operation.
