Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus, and more particularly, to an apparatus for recording moving image signals reproduced from a plurality of recording media on a specific recording medium.

[Prior Art] In conventional off-line editing, for example, as shown in FIG. 2, images of necessary parts A, B, and C of work tapes 7, 8, and 9 are recorded by assembling, and necessary parts of work tape 10 are recorded. The offline master tape 11 is created by recording the image of D by insert. Read the time code from the created master tape.

[Problems to be Solved by the Invention] However, in the above-described conventional example, if the created offline master tape is not reproduced from the beginning to the end, the outline of the master tape cannot be known, and it takes much time.

An object of the present invention is to provide a magnetic recording / reproducing apparatus which has solved the above-mentioned problems.

[Means for Solving the Problems] The present invention is an apparatus for recording an image signal of a new program on a predetermined recording medium on which image signals of a plurality of programs reproduced from at least one recording medium are recorded. A memory for storing one screen image signal at a recording start point of each program extracted from the image signal of each program when the image signals of the plurality of programs are recorded on the predetermined recording medium; and Output means for combining and outputting the stored image signals of each screen;
Extracting means for extracting an image signal of one screen at the recording start point of the new program from the image signal of the new program; and, in the image signal stored in the memory, The image signal of one screen of the recording start point of the program whose recording start point is erased from the recording medium is erased from the memory, and the image signal of one screen according to the new program extracted by the extracting means is deleted. Means for writing an image signal to the memory.

According to the present invention, when recording a new program image signal on a predetermined recording medium on which a plurality of program image signals reproduced from at least one recording medium are recorded, the new program image signal is recorded. For a program whose recording start point is erased along with the recording of the program, an image signal of one screen at the recording start point of the program is erased from the memory, and one screen according to the new program extracted by the extracting means. Is written into the memory.

Embodiment FIG. 1 is a block diagram showing an embodiment of the present invention.
Reference numeral 1 denotes a VTR for reproducing a work tape. Reference numeral 2 denotes a VTR for preparing an offline master tape, which has a signal processing circuit 3, a timing control circuit 4, and a memory 5.

In the above configuration, the video signal of each work tape (for example, FIGS. 7, 8, and 9 in FIG. 2) reproduced by the VTR 1 is sent to the signal processing circuit 3 and recorded on the offline master tape 6. At that time, a write signal is generated from the timing control circuit 4 to the memory 5, and through the switch SW controlled by the circuit 4, the in-point at the time of assembling from the signal processing circuit 3 (for example, E, F in FIG. 2) , G) is written to the memory 5 as a still image (FIG. 3).

At the time of insertion of the work tape 10 shown in FIG. 2, the H image at the in point is written into the memory as shown in FIG. 4, and the F image written earlier is rewritten to the I image.

As described above, the in-point image and time code of each work tape are all written in the memory and stored.

After the creation of the offline master tape, an arbitrary address is designated from the timing control circuit 4, the information of the offline master tape written in the memory 5 is read out, and the information is displayed on the 12 monitors on a multi-screen or the like.
Thereby, the outline of the offline master tape can be grasped in a short time.

[Effect of the Invention] As described above, according to the present invention, at least one
Even when a new program image signal is recorded on a predetermined recording medium on which a plurality of program image signals reproduced from one recording medium are recorded, the recorded content of the edited recording medium is accurately read. You can figure out.
