SpGecloifiscastiaornys Audio recording mode In the DVCAM format, the sound is recorded in either 16bit (Fs48k) or 12bit (Fs32k) mode. Component signal A video signal consisting of a luminance signal (Y) and two chrominance signals (R-Y, B-Y). Condensation Condensation of moisture on the tape transport mechanisms of VCRs including the head drum. If moisture condenses on the head drum, the tape adheres to the drum and causes malfunction. Drop frame mode In NTSC format, the actual number of frames per second is approximately 29.97, while that for SMPTE time code is specified as 30. Drop frame mode is a mode in which time code is advanced in such a way that the difference in frame value between real time and time code is corrected. In this mode, two frames are skipped at the beginning of each minute, except for every tenth minute, so that the frame value for time code matches that for real time. See also "Non-drop frame mode." Drum See "Head drum." EE mode EE is an abbreviation of "Electric to Electric." Video and audio signals are supplied to the VCR's internal circuits, but not to the recording heads. Head drum A metal cylinder to which video heads are attached. During recording and playback, the drum rotates at high speeds in synchronization with the sync signal. Loading When being loaded, the tape is pulled out of the cassette case and threaded along the specified tape path and wrapped round the drum to be ready for recording or playback. Generally, this is done automatically when you place the cassette at the cassette entrance of the VCR. Also called threading. Non-drop frame mode A mode of advancing time code in such a way that the difference in frame value between real time and time code is neglected. Using this mode produces a difference of approximately 86 seconds per day between real time and time code, which may cause problems when editing programs in units of seconds using the number of frames as a reference. PCM audio PCM stands for "pulse code modulation." PCM audio means audio signals that have been processed by pulse code modulation. Each analog audio signal is converted into pulses that are generated in rapid succession, and each pulse is recorded as a digital signal having a value of 0 or 1. Search To locate a particular scene by running the tape in the fast forward or rewind mode while viewing the picture or time codes. Superimpose To put a set of characters onto a picture so that both can be seen at the same time. Threading See "Loading." Time code Signals recorded on the tape to supply information on tape position such as the hour, minute, second and frame, to assist in setting edit points or searching for particular scenes. This unit can cope with both DF (Drop Frame) and NDF (Non Drop Frame). On this unit, the time code is recorded sequently from "00:00:00:00," from the beginning of the tape. However, if there is a blank section on the tape, time code is reset and recorded from "00:00:00:00" again from the section just after the blank section. If the time codes are out of sequence, you may not be able to execute correct editing. Unloading When being unloaded, the tape is put into the cassette case from the tape path of the VCR. Generally, this is done automatically when you press the EJECT button. Also called unthreading. Unthreading See "Unloading." 12bit (Fs32k) mode In the DVCAM format, the 12bit (Fs32k) mode separates the audio area into 2 parts. You can record two kinds of audio, stereo 1 and stereo 2. 16bit (Fs48k) mode In the DVCAM format, the 16bit (Fs48k) mode uses the whole audio area to record one stereo track. You can get higher sound quality. Appendix 60 (GB) Appendix
