BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / playback system using a memory card. In particular, an existing recording event is provided by providing a user with information on an event (program unit of a data recording area: event) previously recorded at the time of insert recording. The present invention relates to a program editing control apparatus using a memory card and a method for insert recording without damage.

In a recording / reproducing system of a general video signal, insert recording is performed while a user does not recognize any information on an existing recorded event in an editing function such as changing or adding a recorded content.

Therefore, when insert recording is performed by the user to add or change contents, there is a problem in that the data of the events before and after the event cannot be protected at all and an accurate edit state cannot be expected.

The present invention has been made to solve the above-described problems of the video signal recording / reproducing system. The present invention searches for event information such as a unique number, a start address, and an end address recorded in an event information area of a memory card, and the user searches for the event information. SUMMARY OF THE INVENTION An object of the present invention is to provide a program editing control apparatus using a memory card and a method thereof in which a residual amount is recognized to protect data of an event before and after a corresponding event and an accurate editing function is performed.

A program editing control apparatus of a recording and reproducing system using a memory card of the present invention for achieving the above object is a recording and reproducing apparatus using a memory card that is recorded and edited in blocks of events in a program unit. Key input means for inputting a control signal related to input / output and a control signal related to insert recording, a memory card storing various data such as an image, a memory controller controlling input / output of the memory card, and a recording signal A recording signal processing means for processing data in a format and storing it in a memory card through the memory controller; and searching for a user by searching the start and end addresses of pre-recorded programs at the time of insert recording using the memory card by the key input. Including a control means for outputting a result It features.

The program editing control method using the memory card of the present invention is a method for editing and controlling a recording and reproducing apparatus using a memory card that is recorded and edited in a program unit block (EVENT). And a step of reading the recording start address of the selected insert event, searching for information such as the start and end addresses of the pre-recorded program, and outputting the retrieved program information.

Hereinafter, a program editing control apparatus and method using the memory card of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a program editing control apparatus using a memory card of the present invention, and FIG. 2 is a block diagram of a memory card during program editing in the recording / playback apparatus of the present invention, and FIG. 3 is a memory card of the present invention. A flowchart showing program editing control using.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / playback apparatus using a memory card in which recording information is managed in unit blocks (Event: program units) according to a user's start and end settings. An event address search unit 40 for searching for an end address, and an event residual calculator 38 for searching for a residual amount of the corresponding event based on the address value of the event address search unit 40 during an insert recording operation selected by a user. ), A warning message output control unit 39 for controlling the output of the external warning message when the minimum value detection signal is output from the event remaining amount calculation unit 38 to control the entire system, and the insert is selected by the user. A microcomputer 31 for controlling a search and an external warning function for data protection of a previous or subsequent event during a recording operation; A memory controller 33 for inputting / outputting data of the memory card 30 under the control of the microcomputer 31, a control signal for input / output of a user, and a control signal for insert recording are inputted to the microcomputer ( The key input means 32 input to 31 and the external recording data A / D converted by the ADC 37 are processed in a specific format and stored in the memory card 30 through the memory controller 33. A playback signal processing means section 36 for processing the playback data of the memory card 30 output through the memory controller 33 according to an external display format and outputting it to the DAC 35; 34).

In the recording and reproducing system using the memory card of the present invention configured as described above, as shown in FIG. 2, the insert event (in FIG. In the recording process of C), before the recording area of the new event (B in FIG. 2) starts, a warning message is output to the outside so that the user can recognize it and make accurate edits. Is input (301), the recording start point address of the selected insert event (A in FIG. 2) is read out (302).

Subsequently, it is determined whether the recording key signal is input (303). If only the recording key signal is input without input of the event setting key, recording starts from the read address (304) (this is not an insertion of a new event, but an existing event). Change or insertion).

If the event setting key signal is input in step 305, a new event is inserted, and thus, the address immediately before the current recording start address is reassigned to the end address of the existing event (A in FIG. 2) and the memory card 30 is reset. The data is stored in the event information recording area (306) (307).

Subsequently, recording recording is started to insert a new event (308).

The remaining amount of events of the inserted portion is calculated at the same time as the recording progress of the above steps 304 and 308 (309).

That is, the remaining memory amount from the current recording position to the start position of the next event already recorded is searched.

When the remaining amount of the event reaches the minimum threshold (310), a warning message is output to the outside to allow the user to recognize the fact (311).

If the user continues to input the recording key at the time of outputting the warning message (312), the recording is continued (ignoring the remaining memory amount of the currently inserted event (A in FIG. 2) (314).

When insert recording is performed until the next event (B in FIG. 2) and the recording stop key is input (315), the end address of the insert event and the start address of the existing event (remaining part of FIG. (316).

If the recording key is not input at the time of outputting the warning message in step 312, the operation after the recording progress is stopped until the start position of the next event (B in FIG. 2).

In step 312, if the recording area changes to the next event (continued to the next event in FIG. 2B) during the continuous recording by the continuous recording signal input, the reference address for event remaining amount calculation is reassigned to the end address of the changed event. .

The program editing control apparatus and method using the memory card of the present invention as described above manage contents to be stored in the memory card in units of events (program units), and information of each event (unique number, start address, end address) In the event information recording area of the memory card, a warning message is output to the outside so that the user recognizes the remaining memory amount by searching for each event information during insert recording.

Therefore, it is possible to effectively protect the data of the event before and after the event, and there is an effect that accurate editing is made.
