Title: Video recording/reproducing device
Inventor: KIJIMA MASAYUKI
IPC: H04N5/781
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To enable quick viewing and listening of an erroneous discriminating part by not performing a CM skip operation from an interrupting point till the detection of the next CM end signal when the fast-forward-reproducing of a CM part by a CM start signal is interrupted and a rewinding is performed and then a normal reproduction is performed. SOLUTION: If an operation changing request such as a request of stop, a request of rewind or the liek is transmitted from a key input device 16, the key input device 16 becomes a request receiving state. Then, the CM end signal from a CM positional information reading/writing circuit 17 is monitored, and if the CM end signal is not received, an operational request from the key input device 16 is received. Thus, a fast-forward operation by the CM start signal becomes forbidden state in changing the operation by the key input under CM- skipping, and the part which is fast-ford-reproduced by the CM start signal is rewound by manual, and in reproducing, the normal reproduction is continued without responding to the CM start signal. Then, the CM end signal is received from the CM position information reading/writing circuit 17, and the inhibition of the fast-forwarding operation is released.
