Caution on video signals ● If search images or video signals with a high level of jitter are input, images or sound may be distorted temporarily. Thus, input stable signals, e.g., those having gone through a TBC. ● A digital VCR requires that video signals for recording be delivered from a stable source. Video signals from an analog VCR must be run through a TBS or TBC. ● When a component output is executed for composite-input video, discoloration may occur on the left side of the screen. It is not a defect. Ⅵ Synchronization signal In order to enhance the level of edit precision, input synchronization signals to all the devices of the editing system during editing. For BR-DV6000, input external synchronization signals into the SYNC IN terminal. For external synchronization signals, use video signals of 1V (p-p) or lower (e.g., black burst signals). To edit DV signals, synchronization signal input is required. Types of synchronization signal: BR-DV6000 is operated based on one of the following 3 types of synchronization signal. • Synchronization signals produced by the syn- chronization signal generator inside the VCR (INT) • Video signals from the video signal input terminal (VIDEO) • Synchronization signals from the SYNC IN terminal (EXT) Selection of synchronization signals: Synchronization signals should be selected depending on whether external synchronization input (SYNC IN) or video input (VIDEO IN) exists or on the SYNC SELECT Menu settings. Synchronization signals are selected as shown in the following table. SYNC IN No Yes No Yes VIDEO IN No No Yes Yes Playback INT EXT INT EXT EXTERNAL❈ Record INT INT VIDEO VIDEO AUTO❈ Playback INT EXT VIDEO EXT Record INT INT VIDEO VIDEO ❈ The above can be selected with SYNC SELECT in the SYSTEM Menu screen. Memo ● During DV signal recording, the status of synchronization signals will be as shown below regardless of the SYNC SELECT menu settings. SYNC IN terminal signal Input No input Synchronization signals EXT DV ● Regardless of the setting of SYNC SELECT, when a tape recorded in PAL is played back, synchronization signals are as shown below. SYNC IN terminal PAL signal input NTSC signal input or No signal input Synchronization signals EXT INT Caution on synchronization signals ● For external synchronization signals, outputsignal phase adjustments cannot be performed. In addition, the sub carrier cannot be locked. ● Plugging and unplugging of external synchronization signals or video input signals during playback causes distortion of images and sound for about 5 seconds. 29
