In practice, "IRIG Zeitcode" refers to an (typically IRIG-B) that carries absolute date and time—often used to synchronize audio recorders, video servers, and logging systems when traditional LTC or MTC isn’t suitable or when legacy RF/radio links are involved.
Here’s a clear, useful write-up on —explaining what it is, why it matters, and how to use it effectively.
This represents the date and time: 09 (day of the month), 12 (month), 31 (year, where 91 represents 1991 or 2091, depending on the context), 12 (hour), 00 (minute), 00 (second), and .000 (fractions of a second). irig zeitcode
The iRig Timecode is a revolutionary device designed by iRig, a renowned brand in the music and film production industry. It's a compact, portable, and user-friendly timecode generator that allows you to sync your audio and video tracks with ease. The iRig Timecode is specifically designed for use with iOS devices, such as iPhones and iPads, making it an ideal solution for filmmakers and musicians on the go.

In broadcast, IRIG-B unmodulated (DC level shift) is common because it can be distributed over balanced audio lines (XLR) without high-frequency carrier issues.
data speed [1, 13]: IRIG-B : The most popular format today, widely used in the electrical power industry [9, 10]. It features a pulse rate of 100 pulses per second, providing high-precision timing with sub-microsecond accuracy [9, 11]. IRIG-E: A slower format with 10 pulses per second, used when bandwidth or device capabilities are more limited [13]. IRIG-G: The "speed demon" of the family, providing 10,000 pulses per second for ultra-high-resolution needs. Modulated vs. Unmodulated How the signal is physically sent also matters [1]: Unmodulated (DCLS): A digital signal (Direct Current Level Shift) sent over short distances via copper wire or fiber optics. It’s simple and highly accurate [1, 10]. Modulated (AM): The data is "carried" on an analog sine wave (often 1000 Hz for IRIG-B). This allows the signal to be transmitted over longer distances or recorded onto standard audio equipment [1, 13]. Why Not Just Use NTP or PTP? You might wonder why we still use serial timecodes in the age of the internet. While Network Time Protocol (NTP) is great for computers, IRIG offers dedicated, hardware-level precision that is immune to network congestion and jitter [12]. It remains essential for: Power Substations: Synchronizing event recorders and protection relays. Aerospace: Tracking telemetry data from rockets and aircraft. Research Labs: Ensuring high-speed cameras and sensors capture data at the exact same instant. The Bottom Line IRIG timecodes are the unsung heroes of precision engineering. By providing a rugged, reliable, and standardized way to share time, they ensure that complex systems—from power grids to missile ranges—operate in perfect harmony.

| Feature | IRIG Zeitcode | SMPTE LTC | |--------|--------------|-----------| | | Fixed (e.g., 100 bps for B) | 80/29.97 to 30 fps (e.g., 2400 bps for 30 fps) | | Time type | Absolute (date + time of day) | Relative (time since midnight, no date) | | Dropout tolerance | High (slow bit rate, strong edges) | Lower (higher frequency) | | Common use | Remote/radio sync, logging, power plants, scientific | Video/audio post, editing, multi-track recording |
In der modernen Medienproduktion ist das Timing alles. Ob Sie ein komplexes Musikvideo drehen, ein Live-Konzert mit mehreren Kameras aufzeichnen oder Field-Recordings für das Sounddesign sammeln – die exakte Synchronisation zwischen Bild und Ton ist die Grundvoraussetzung für ein professionelles Ergebnis. Hier kommt der Begriff (oder Timecode) ins Spiel, und im mobilen Bereich haben sich die Produkte von IK Multimedia (iRig) als Brückenbauer zwischen analoger Audiowelt und digitaler Präzision etabliert. Was ist Zeitcode (Timecode) überhaupt?
IRIG Zeitcode is not something you’ll find in a home studio, but in specialized broadcast, industrial, or multi-day recording scenarios, it’s a bulletproof, long-distance, absolute time reference that SMPTE LTC cannot replace. If your work touches legacy German broadcast gear or telemetry systems, understanding IRIG-B will save you hours of head-scratching.
Wenn eine Kamera keinen dedizierten Timecode-Eingang besitzt, kann der Zeitcode als "hörbares" Signal (Linear Time Code - LTC) auf einer Audiospur aufgezeichnet werden.
