The Dcode SB-T Trilevel Syncbox Generator With 3D Time Code from Denecke reads, generates, and jams to all the standard frame rates including 23.976 for High Definition video. The outputs include time code and video sync in PAL and NTSC, as well as Trilevel for HD shoots. The Temperature Compensated Crystal Oscillator (TCXO) ensures low drift. High stability and ease of use make it useful for any high or standard definition shoot.
The Dcode SB-T generates all common SMPTE time code rates and video references in 1920 x 1080 (Sony) and 1280 x 720 (Panasonic) HD standards. Standard Definition (29.970 fps non-drop & drop frame) and PAL (25 fps) black burst or color bars are generated as well. Three LEDs indicate battery status, sync / internal run, and presence of external power.
Three AA batteries power the SB-T or it can be powered externally through a 4-pin Hirose or a 5-pin Lemo (sold separately). The amber LED indicates the battery status. If it is Off, it means the battery is good (assuming unit is On). If the LED flashes once per second, it means the battery is low, and if it flashes twice per second, it means the battery is dead. The batteries should be replaced as soon as possible when dead battery is indicated. External power is indicated when the red LED is on. When external power is removed, internal battery power change over is automatic and the red LED turns Off.
The sync LED (green) indicates whether the SB-T is in a Jamsync mode or in an Internal Run mode. The sync LED flashes once per second (at the start of the frame 00) when in Jamsync mode or if the SB-T has been running in Internal Run mode for 10 minutes. The SB-T features an automatic Jamsync capability which re-jams to any break in time code without the need to power down.
The jam occurs at the 00 frame so cross jamming of different rates can be accomplished. Internal Run mode is indicated by the sync LED strobing. When the SB-T is turned on without time code present at its input, it will generate its own time code / video reference starting at 00:58:30:00.
The TC frame rate and video reference are dependent upon the switch settings. Pressing the set button will increment the minutes, while holding down the set button will scroll the minutes. The minutes roll over into the hours, therefore enabling control of the hours and minutes. The time code rate rotary switch serves 2 functions. It selects a time code frame rate as well as a video reference. For example, position 4 selects 23.976 fps time code as well as a Trilevel sync video reference.
Note: The TC rate and mode switches are locked out to prevent accidental change of the settings and the unit must be powered down for different switch setting to take affect.
- Generates Trilevel Sync in all 1920 x 1080 and 1280 x 720 formats, composite PAL and NTSC, as well as all standard time code rates
- Cross jams regardless of incoming frame rates
- Jam from an external time code source or set it internally and use as a stand alone generator
- Continuously jams to new code so there is no need to power down the unit to re-jam
- Runs on 3 AA batteries or can be powered externally through a 4-pin Hirose plug and use the AA batteries as a backup when the camera is powered down
- 5-pin Lemo socket (sold separately) can be used instead of 4-pin Hirose
- Low and dead battery warning
