A circuit 55, a front circuit 61 including a selection switch / warning indicator, etc., a back circuit 60 associated with the audio / video input / output jack, etc., a power supply circuit 62 of the system, and the like. Doing.

Further, when the deck units 51 to 53 are coupled to the copying apparatus main body 5 side, connection points including A, B, and C points are connected as shown in FIG. 3 so that the copying unit main body 5 and the deck units 51 to 53 are connected. When the external video signal for video copy / playback is connected to the audio input (AI) and the video input (VI), respectively, while the connection state between them is established, the tape copying operation is performed through the deck units 51 to 53. will be.

The purpose of the present invention is to facilitate the use of such a system by changing the position of OSD characters on the screen for the Vsial set during the playback / copy operation by the number of Vsial to Vsial lines. It is.

In particular, the present invention provides a video processor for reproducing / recording the video signal of the VSI system to implement the object of the above example, and the character data provided from the OSD character generator after being connected to the output of the video processor. An OSD processor which is synthesized and provided to the character information input / output selection unit, an OSD character generator connected to the OSD processor to generate the OSD character data, and information on the position of the character data generated by the OSD character generator It is characterized by the OSD character overlap prevention system during playback / recording by a plurality of VSI connections of a configuration including an up / down / left / right information register for providing an OSD character generator and a system microcomputer.

In more detail with reference to the accompanying drawings it will be understood that more specific features of the present invention.

13. Microcomputer 14. Character information input / output selection unit

15. OSD character generator 16. Up / down / left / right movement information register

That is, Figure 5 shows the main circuit block of the OSD D overlapping prevention system during playback / recording by the multiple VSI connection according to the present invention.

In this example, the video processing unit 11 which plays / records a video signal in the system, and the character data provided from the output of the video processing unit 11 and provided by the OSD character generator 15 together with the composite synchronization signal are combined with the video signal. An OSD processor 12, which is formed in the form of a data element and is provided to the character information input / output selection unit 14, is connected to the OSD processor 12, and generates an OSD character data. Up / down / left / right information registers 16 which provide the OSD character generator 15 with information on the position of the character data generated by the OSD character generator 15, and the microcomputer 13 of the system control. It consists of a configuration including the back.

The present invention of such a configuration is a character position A when the output of VSI1 is input to the VSI2 when the playback / copy operation is performed by connecting a plurality of VSIALs in line-to-line as shown in FIGS. 5 and 6. The OS character generator 15 inputs the A character information and registers the content in the up / down / left / right movement information register 16 so as to be located at.

In processing this A, an external signal or information inputted from the video processing unit 11 of the system is outputted and provided to the processed OSD processor 12, and the OSD processor 12 transmits an OSD clock and an OSD character generator. A video signal is formed using the character data provided from (15).

At this time, the OSD character generator 15 receives the movement information of the up / down / left / right movement information register 16 and provides the position information to the data transmitted to the OSD processor 12.

The OSD character generator 15 generates and outputs a character called VSI1 at position A, and this information is output through the OSD processor 12, which is output through the character information input / output selector 14. Will be printed on

If Vsial 2 and Vsial 3 are connected in series, the character position designates the data of the B position and performs the same operation as when Vsial 1 and Vsial 2 are connected. The character position of VSI 4, etc., designates the C position and operates to be output.

By doing so, it is programmed to move the character position at the time of connection connection such as Vialal 1 → Vialal 2 → Vialal 3 → Vialal 4, and it is possible to perform the above operation by connecting up to 5 units. will be.

On the other hand, the above operation is performed in the same procedure as in FIG. 6, where a plurality of VSIAL sets are connected in a line to check whether the playback mode or the recording (REC) mode is selected. SIAL 2 runs in the recording mode, and the screen output is input to V3.

At this time, the reproduction VP1 is registered in the A register, and the recording VP1 is registered in the B register.

After that, V2 is stored in the BB register and V3 is stored in the BB register, and the pass mode is stored in the CC register.

After selecting the character position, the contents of the A, B, C, and CC registers are respectively displayed on the TV receiver screen.

In the recording mode, the VSI 1 is the recording and the VSI 2 is passed, and the screen configuration is AA, BB to form a character register and output the character position selection to the AA, BB position.

The present invention is such that the set distinct OSD screens appearing in the screen company can be displayed at predetermined positions without overlapping each other in the process of reproducing / recording a plurality of VSIs through a connection of the Vsial to the Vsial line. The convenience of using the system can be secured well.
