发明名称 REPRODUCING DEVICE WITH AUTOMATIC CHANGE-OVER BETWEEN TRICK-PLAY SPEEDS
摘要 In a reproducing device (1) for the reproduction of reproduction data (WD) recorded on a magnetic tape (2), having transport means (7) for the transport of the magnetic tape (2) with a normal-play speed (VNS, VNLS2, VNLS3, VNLS5, VNLS7, VNHS), a first trick-play speed (VT1) and at least a second trick-play speed (VT2, VT3), the normal-play speed (VNS, VNLS2, VNLS3, VNLS5, VNLS7, VNHS) corresponding to a recording speed during the recording of the reproduction data (WD) on the magnetic tape (2), and having reproducing means (13) for the reproduction of normal-play reproduction data (NPD1, NPD2, NPD3, NPD4, NPD5) recorded on the magnetic tape (2) during transport of the magnetic tape (2) with the normal-play speed (VN), of first trick-play reproduction data (TPD1, TPD6) recorded during transport of the magnetic tape (2) with the first trick-play speed (VT1), and of second trick-play reproduction data (TPD2, TPD3, TPD4, TPD5, TPD7) recorded during transport of the magnetic tape (2) with the second trick-play speed (VT2, VT3), test means (23) have been provided for testing whether during transport of the magnetic tape (2) with the first trick-play speed (VT1) valid first trick-play reproduction data (TPD1, TPD6) is reproduced, and the test means (23) are adapted to supply control information (SI) to the transport means (7) in the absence of reproduced valid first trick-play reproduction data (TPD1, TPD6) during a test interval (T), in order to cause a transport of the magnetic tape (2) with the second trick-play speed (VT2, VT3).
