When a time code signal corresponding to an image signal, to which a format conversion changing the number of frames per second is executed, is transmitted, information indicating a frame position where image data is changed through the format conversion in the image signal is attached to the time code signal to be transmitted. Alternatively, information indicating a synchronous state between frame conversion cycles in the format conversion and time code progression is attached to the time code signal. In the foregoing manner, a relationship between the frame position and the time code can be accurately grasped. Further, a secondary conversion (inverse conversion) is accurately executed to the image signal by means of the time code signal.

Video signal format secondary-conversion method, time code signal transmission method, and time code transmitting apparatus

A video signal recording and reproduction device of this invention uses one of a plurality of terminals for receiving input of component video signal to also serve as a composite video signal input terminal, thereby reducing a number of the input terminals. This realizes a reduction in size of the device, yet maintains the device to be capable of receiving both inputs of component video signal and composite video signal. The video signal recording and reproduction device of this invention also uses one of a plurality of terminals for outputting component video signal to also serve as a composite video signal output terminal, thereby reducing a number of the output terminals. This realizes a further reduction in size of the device, yet maintains the device to be capable of providing both outputs of component video signal and composite video signal.

The present invention comprises the step of reading a check-receiving data included in a transmitted time code signal and using the read check-receiving data to generate a transmitting side checking data, and the step of attaching the transmitting side checking data to the transmitted time code signal, as a pre-processing step at the time of transmitting the time code signal. The present invention comprises the step of reading the check-receiving data from the received time code signal and using the read check-receiving data to generate a receiving side checking data, and the step of reading the transmitting side checking data from the received time code signal and comparing the read transmitting side checking data to the receiving side checking data, thereby verifying whether or not an error is generated in the received time code signal. In this way, an error can be detected in the time code signal, as a post-processing step after the time code signal is received.
