摘要： When a played scene of a VCR (sequential access recorder) (90) is overwritten or added to the play list derived from the cut edit of the video scenes already stored in a disk (random access recorder) (140) according to the first instruction of a user, a selector (96) switches the play output of the disk following the play list and said played scene of the VCR to provide it to a monitor (6A) so that the user can confirm the edit result during the recording in real time. If there is the second instruction (VIEW instruction) during the recording, it plays the same edit result of the disk (140) again based on the renewed temporary play list to provide it to the monitor (6A) without interrupting the recording. On this occasion, it approves the user to change the play speed and stops advancing the play if the user try to play beyond the recorded point. Then, the user can confirm the recorded video portion without waiting the completion of the recording and without interrupting the recording even during the recording from the external VCR.

摘要： A communication controlling apparatus comprising a transmission line error detecting circuit 30 which determines whether a transmission line error is detected or not in the data transmitted from its own node without immediately disabling a P-channel MOS transistor 20 or N-channel MOS transistor 21 as output gates when an error is detected in one of the transmission lines (BUS+line 11 or BUS-line 12), a sequence control circuit 31 which informs all the other nodes that the error is detected in its own node, and a selector 27 which determines whether the transmission line error detecting circuit 30 has detected or not the transmission line error in the transmit start (SOF) period and selects a differential comparator. The reliability of communication is improved when an error is detected in one of the transmission lines.
