能を有している。The video recording/playback device with an automatic format conversion function of the present invention includes a format detecting means for automatically detecting which TV format is used for recording from a recorded tape playback signal, and a corresponding signal based on the detected and identified results. It has a format switching means for switching the processing, and an image format conversion function for sending out an output signal converted to a format compatible with the format of the connected television receiver.
次に本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

えられた信号で送り出される。One of the tapes 1 to 3 recorded in each of the TV formats of NTSC, PAL, and SECAM is set in the main body 4, and the input signal a obtained by playing back from the tape is sent to the signal processing function 5.
is transmitted to the method detection function and method switching function, and is outputted from the method detection function and method switching function 7. The system switching control signal C switches the signal processing function 5 and the image system converting function 6 to correspond to the signal system reproduced from the set tape. The signal output from the signal processing function 5 is connected to a television receiver 8, and is always sent out as a signal switched to a format compatible with the television receiver 8, no matter which format tape is set.

。Based on the running control signal, video synchronization signal, and color subcarrier signal included in the signal a obtained by reproducing from a tape recorded in each different method, the method detector and method switching function 7 determine the signal to be reproduced from the tape. It automatically determines which system it is, and uses the output system switching control signal C obtained as a result of the determination to switch the signal processing function 5 to support that system.
(25 lines) and PAL/SECAM (625 lines) are converted by an image format conversion function 6 into a video output signal 6 compatible with being sent to a television receiver and sent out.
